SR804N Cable Modem User Manual 4.1 PC Network Configuration and Login PC Network Configuration Each network interface on the PC should either be configured with a statically defined IP address and DNS address, or be instructed to automatically obtain an IP address using the network DHCP server. SR804N provides a DHCP server on its LAN and it is recommended to configure your LAN to automatically obtain its IP address and DNS server IP address. The configuration principle is identical but should be carried out differently on each operating system. The following displays the TCP/IP Properties dialog box on Windows XP. SR804N Cable Modem User Manual Figure 1 IP and DNS configuration TCP/IP configuration steps for Windows XP are as follows: Step1 Choose Start > Control Panel > Network Connections. Step2 Right-click the Ethernet connection icon and choose Properties. Step3 On the General tab, select the Internet Protocol (TCP/IP) component and click Properties. Step4 The Internet Protocol (TCP/IP) Properties window appears. Step5 Select the Obtain an IP address automatically radio button. SR804N Cable Modem User Manual Step6 Step7 4.2 Select the Obtain DNS server address automatically radio button. Click OK to save the settings. Logging In to the SR804N Cable Modem To log in to the SR804Ncable modem, do as follows: Step1 Open a Web browser on your computer. Step2 Enter http://192.168.100.1 (the default IP address of the SR804Ncable modem) in the address bar. The login page appears. Step3 Enter the user name and the password. The default Username is admin and the Password is admin. Step4 Click OK to log in to the Web page. Otherwise, please click Cancel to exit the login page. Figure 2 Login page After logging in to the SR804N cable modem, you can query, configure, and modify all the settings, and diagnose the system. SR804N Cable Modem User Manual Web-Based Management This chapter describes how to use Web-based management of the Cable Modem, which allows you to configure and control all of cable modem residential gateway features and system parameters in a user-friendly GUI. 5.1 Status Choose Status, and the submenus of Status are shown as below. Figure 3 Submenus of Status 5.1.1 Software Choose Status > Software , and the following page appears. 10 SR804N Cable Modem User Manual Figure 4 Software page This page displays information about the hardware version, software version, MAC address, cable modem IP address, serial number, system “up” time, and network registration status. 5.1.2 Connection Choose Status > Connection and the following page appears. Figure 5 Connection information This page displays information about the RF upstream and downstream channels, including downstream channel frequencies, upstream channel IDs, and upstream and downstream signal power and modulation. 11 SR804N Cable Modem User Manual This page also displays IP lease information, including the current IP address of the cable modem, the duration of both leases, the expiration time of both leases, and the current system time from the DOCSIS timeserver. The information on this page can be refreshed at any time by clicking your web browser‟s Refresh button. 5.1.3 Security Choose Status > Connection and the following page appears. Figure 6 Security configuration To restore factory defaults, select the Yes radio button and click Apply. This will cause the device to reset. The factory default password is “Broadcom” and is case sensitive. Note that you can also change the security password from this page by entering a new password in both the New Password and Re-Enter New Password fields, and the current password in the Current User ID Password field. Clicking Apply will change the password. You do NOT have to restore factory defaults to change the password. 5.1.4 Diagnostics Choose Status > Diagnostics and the following page appears. 12 SR804N Cable Modem User Manual Figure 7 Diagnostic information Two utilities are provided for troubleshooting network connectivity: Ping and Traceroute. Ping allows you to check connectivity between the CMRG and devices on the LAN. Traceroute allows you to map the network path from the CMRG to a public host. Selecting Traceroute from the drop-down Utility list will present alternate controls for the traceroute utility: To run either utility, make any changes to the default parameters and select Start Test to begin. The window will automatically be refreshed as the results are displayed in the Results table. 5.1.5 Event Log Choose Status > Event Log to display the following page. 13 SR804N Cable Modem User Manual Figure 8 Event Log information This page displays the contents of the SNMP event log. 5.2 Basic Choose Basic and the submenus of Basic are shown as below. Figure 9 Submenus of basic 5.2.1 Setup Choose Basic > Setup , and the following page appears. 14 SR804N Cable Modem User Manual Figure 10 Setup configuration Enter the information from the Required Information section as indicated: 1.If your ISP uses DHCP, select “DHCP” for the WAN Connection Type, and enter Host Name and Domain name if required. OR If your ISP uses static IP addressing, select “Static IP” for the WAN Connection Type, and enter the information provided by your ISP for Static IP Address, Static IP Mask, Default Gateway, Primary DNS, and Secondary DNS. 2.Enter a unicast MAC address in the Spoofed MAC Address field. Your ISP may require this to be your PC‟s MAC address. If not, you can simply supply the WAN side MAC address of the router as your CPE and leave the spoofed MAC address entry set to all 0‟s, since there will be no spoofing required. 3.Select the Apply button. This will reset the CMRG. At this point, the CMRG is configured for basic use. To connect to the Internet, you must do the following: 1.Power up the CMRG and wait for it to register with the CMTS and obtain an Internet-routable IP address 2.Get an IP lease from the internal DHCP server for each PC attached to the CMRG. 15 SR804N Cable Modem User Manual Note that communication on the LAN will work regardless of whether the WAN connection provided by the cable modem is up. However, you will not be able to access the Internet until the WAN connection is enabled and has an IP address. Some configurations settings are retrieved only once from non-volatile storage when the CMRG first powers up. One such setting is changing the Static WAN IP address parameters. Any changes to these settings will force the CMRG to reset so that the new configuration can be read from non-volatile storage. When this mandatory reset is required, the web interface will notify as follows: Figure 11 Reload page Simply wait for the modem to reboot and click on the “RELOAD” link to re-enter the web interface where you made your last change. Most configuration items may be changed on the fly without a reboot. 5.2.2 DHCP Choose Basic > DHCP, and the following page appears. 16 SR804N Cable Modem User Manual Figure 12 DHCP configuration This page allows configuration and status of the optional internal DHCP server for the LAN. If you have your own DHCP server servicing the LAN side (or choose to “hardcode” all of your PC‟s IP addresses), you can disable the internal DHCP server by selecting the No radio button. If you do this, make sure the IP address assigned to the CMRG is on the same subnet as the external DHCP server (the subnet mask is always 255.255.255.0), or you won‟t be able to access the CMRG from the LAN. The IP address of the CMRG can be set from the Basic Setup page. You can also set the starting IP address for IP leases available to the LAN, and change the number of PCs supported on the LAN. In the case above, addresses 192.168.0.2 through 192.168.0.9 can be used as hard-coded IP addresses with no fear of IP address conflict with the DHCP pool. Configured WINS server addresses can also be passed to CPEs behind the CMRG via DHCP. 5.2.3 DHCPv6 Choose Basic > DHCPv6 , and the following page appears. 17 SR804N Cable Modem User Manual Figure 13 DHCPv6 configuration This page allows configuration of the internal DhcpV6 server for the LAN. When modifying the System Delegated Prefix, set the System Delegated Prefix first, and press Apply so that the system can calculate its LAN Delegated Prefix. 5.2.4 LAN IPv6 Choose Basic > LAN IPv6 , and the following page appears. Figure 14 LAN IPv6 information This page displays information related to IPv6 on the LAN. 5.2.5 DDNS Choose Basic > DDNS , and the following page appears. 18 SR804N Cable Modem User Manual Figure 15 DDNS setup This page is used to configure DDNS. Dynamic DNS (DDNS) allows a dynamic IP address to be aliased to a static, pre-defined host name so that the host can be easily contacted by other hosts on the internet even if its IP address changes. The CMRG supports a dynamic DNS client compatible with the Dynamic DNS service (http://www.dyndns.com/). To activate the DDNS client: 1. Go to the DynDNS website and create an account for the Dynamic DNS service. You will create a username and password, and be asked to choose a host name for your server, and the dynamic DNS domain to which your host will be assigned. You will also be asked for your host‟s current IP address. This is the WAN IP address that has been assigned to your CMRG during provisioning. (See WAN IP Address on the Basic / Setup web page.) 2. Enter your account information on the Basic / DDNS web page, enable the service by selecting www.DynDNS.org from the DDNS Service drop-down list, and click Apply. 3. The DDNS client will notify the DDNS service whenever the WAN IP address changes so that your chosen host name will be resolved properly by inquiring hosts. The current status of the service is shown at the bottom of the DDNS web page. 5.2.6 Backup Choose Basic > Backup and the following page appears. 19 SR804N Cable Modem User Manual Figure 16 Backup In this page, you can save the current CMRG configuration settings to a local PC. You can then later restore these settings if you need restore a particular configuration, or to recover from changes you may have made that have had an undesirable effect. To backup the current configuration, click Backup and follow the prompts. To restore a previous configuration, click Browse and use the navigation window to locate the file. (Usually GatewaySettings.bin, unless you rename it before saving.) Once the file has been located, click Restore to restore the settings. Note that once the settings are restored, the device will reboot. 20 SR804N Cable Modem User Manual 5.3 Advanced Choose Advanced and the submenus of Advanced are shown as below. Figure 17 Submenus of advanced 5.3.1 Options Choose Advanced > Options to display the following page. 21 SR804N Cable Modem User Manual Figure 18 Advanced options This page allows you to configure the accessible features. To enable a feature, click the appropriate check box until it is “checked”. When you are satisfied with your selections, click on the Apply button. These features can be modified on the fly without a system reset. “WAN Blocking” prevents the CMRG or the PCs behind it from being visible to the WAN. For instance, pings to the CMRG‟s WAN IP address or the PCs behind it are not returned. Therefore, it will be more difficult for hacker to discover your WAN IP address to begin an attack on your private LAN. “IpSec” and “PPTP” (Point-to-Point Tunneling Protocol) pass-through modes enable these protocols to be used through the CMRG such that a VPN device (or software) may communicate properly with the WAN. “ Remote Configuration Management” allows the CMRG to be administered (configured) from the WAN via surfing to the WAN IP address on port 8080 of the CMRG from anywhere on the Internet (e.g. at the browser URL window enter http://WanIPAddress:8080/ to access the CMRG remotely). 22 SR804N Cable Modem User Manual “Multicast Enable” allows multicast specific traffic (denoted by a multicast specific address) to be passed to and from the PC‟s on the private network behind the CMRG. “UPnP Enable” enables the UPnP agent in the CMRG. If you are running a CPE application that requires UPnP, check this box. 5.3.2 IP Filtering Choose Advanced > IP Filtering to display the following page. Figure 19 IP Filtering configuration This page allows you to configure the CMRG to prevent local PCs from getting access to the WAN by specifying those IP addresses that should be filtered. By entering starting and ending IP address ranges, you can configure which local PCs are denied access to the WAN. Note that you only need to enter the LSB (Least-significant byte) of the IP address; the upper bytes of the IP address are set automatically from the CMRG IP address. To activate the IP address filter, you must also check the “enable” box and click apply. The enable box allows you to store filter settings commonly used but not have them active. 5.3.3 MAC Filtering Choose Advanced > MAC Filtering to display the following page. 23 SR804N Cable Modem User Manual Figure 20 MAC filtering configuration This page is used to prevent PCs from sending outgoing TCP/UDP traffic to the WAN via their MAC address This is useful for the fact that the MAC address of a specific NIC card never changes, unlike its IP address which can be assigned via DHCP server or hard-coded to various addresses over time. 5.3.4 Port Filtering Choose Advanced > Port Filtering to display the following page. 24 SR804N Cable Modem User Manual Figure 21 Port Filtering configuration This page is used to prevent PCs from sending outgoing TCP/UDP traffic to the WAN on specific IP port numbers. By specifying a starting and ending port range, you may determine what TCP/UDP traffic is allowed out to the WAN on a per-port basis. Note the specified port ranges are blocked for ALL PCs and this setting is not IP address or MAC address specific. For instance, if you would like to block all PCs on the private LAN from accessing HTTP sites (or “web surfing”), you would set the “Start Port” to 80, the “End Port” to 80, the “Protocol” to TCP, check the “Enabled” box, and click Apply. 5.3.5 Forwarding Choose Advanced > Forwarding to display the following page. Figure 22 Forwarding This allows for incoming requests on specific port numbers to reach web servers, FTP servers, mail servers, etc. so they can be accessible from the public internet. A table of commonly used port numbers is also provided. Forwarding allows you to run a publicly accessible server on the LAN by specifying the mapping of TCP/UDP ports to a local PC To specify a mapping, you must enter the range of port numbers that should be forwarded locally, and the IP address to which traffic to those ports should be sent. If only a single port specification is desired, enter the same port number in the “start” and “end” locations for that IP address. A table of commonly used Port numbers is supplied on the page for convenience. 25 SR804N Cable Modem User Manual If both external and Local/internal port numbers are present, the Local port number is a mandatory field and the external port number is optional. If the external port number is used, the RG will perform a translation from external port number to internal port number. 5.3.6 Port Triggers Choose Advanced > Port Triggers to display the following page. Figure 23 Port Triggers Port Triggers are similar to Port Forwarding except that they are not static ports held open all the time. When the CMRG detects outgoing data on a specific IP port number set in the “Trigger Range”, the resulting ports set in the “Target Range” are opened for incoming (or sometimes referred to as bi-directional ports) data. If no outgoing traffic is detected on the “Trigger Range” ports for 10 minutes, the “Target Range” ports will close. This is a safer method for opening specific ports for special applications (e.g. video conferencing programs, interactive gaming, file transfer in chat programs, etc.) because they are dynamically triggered and not held open constantly or erroneously left open via the router administrator and exposed for potential hackers to discover. 5.3.7 DMZ Host Choose Advanced > DMZ Host to display the following page. 26 SR804N Cable Modem User Manual Figure 24 DMZ Host setup DMZ (De-militarized Zone) hosting (also commonly referred to as “Exposed Host”) allows you to specify the “default” recipient of WAN traffic that NAT is unable to translate to a known local PC. This can also be described as a computer or small sub-network that sits between the trusted internal private LAN, and the untrusted public Internet. You may configure one PC to be the DMZ host. This setting is generally used for PC‟s using “problem” applications that use random port numbers and do not function correctly with specific port triggers or port forwarding setups mentioned earlier. If a specific PC is set as a DMZ Host, remember to set this back to “0” when finished with the needed application, since this PC will be effectively exposed to the public Internet, though still protected from Denial of Service (DoS) attacks via the Firewall. 5.3.8 RIP Setup Choose Advanced > RIP Setup to display the following page. 27 SR804N Cable Modem User Manual Figure 25 RIP Setup RIP (Router Information Protocol) is used in WAN networks to identify and use the best known and quickest route to given destination addresses to help reduce network congestion and delays. NOTE: RIP messaging will only be sent upstream when running in Static IP Addressing mode on the Basic – Setup page. You must enable Static IP Addressing and the set the Wan IP network information! RIP is normally a function that is tightly controlled via the ISP. RIP Authentication Keys and IDs are normally held as secret information from the end user to prevent unauthorized RIP settings. RIP is a protocol that requires negotiation from both sides of the network (i.e. CMRG and CMTS). The ISP would normally set this up because of their knowledge of their CMTS settings to match the configuration in the CMRG. To enable the CMRG to perform RIP, do the following (this example uses BRCMV2 as the RIP Authentication Key and 1 as the Key ID): 1.) To turn on RIP MD5 Authentication, check the “Enable” box. 2.) To specify a RIP MD5 Authentication Key String, type “BRCMV2” for this example. key name = a string value to match CMTS key name value 3.) To specify a RIP MD5 Auth Key ID, type “1” key number = a number to match the CMTS key number value 4.) To change the RIP annoucement interval, type in a number in seconds.reporting interval by default = 30 seconds 5.) To specify a RIP unicast destination IP address, enter the IP address and subnet mask. To enable the CMTS for RIPv2 with MD-5 authentication (Cisco uBR example shown below): 1.) The following steps go through configuring RIPv2 for a Cisco CMTS. The network number used in this configuration will vary from network to network so use the network number that matches your set-up. 7223#configure terminal 7223(config)#key chain ubr 7223(config-keychain)#key 1 28 SR804N Cable Modem User Manual 7223(config-keychain-key)#key-str BRCMV2 7223(config-keychain-key)#exit 7223(config-keychain)#exit 7223(config)#router rip 7223(config-router)#ver 2 7223(config-router)#no validate-update 7223(config-router)#passive-interface cable 2/0 7223(config-router)#network 10.0.0.0 7223(config-router)#exit 7223(config)#inter cable 2/0 7223(config-if)#ip rip receive ver 2 7223(config-if)#ip rip authentication mode md5 7223(config-if)#ip rip authentication key-chain ubr 7223(config-if)#exit 7223(config)#exit In this example, we have named the key chain „ubr‟. This was chosen arbitrarily. You can use any name you like as long as you specify the correct name when specifying which key chain to use for RIPv2 authentication. 2.) The next step is enable RIP debugging to ensure that the CMTS is receiving and authenticating messages from the residential gateway. 7223#debug ip rip RIP protocol debugging is on 7223#term mon The CMTS is now configured to accept RIPv2 messages. If the CMRG is registered on the CMTS, you should see messages that are similar to the message below: 00:28:41: RIP: received packet with MD5 authentication 00:28:41: RIP: received v2 update from 10.24.81.148 on Cable2/0 00:28:41: 10.24.81.0/24 via 10.24.81.148 in 1 hops The CMRG has broadcast that is connected to the network 10.24.81.0/24 through the interface 10.24.81.148. This information is not very useful to the CMTS because it already knows that the network 10.24.81.0/24 is connected directly to one of its interfaces (Cable2/0). It ignores this message and doesn‟t add any information to the IP routing table. Here is the IP routing table after the CMTS has received RIPv2 messages: 7223#sh ip route 29 SR804N Cable Modem User Manual Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area * - candidate default, U - per-user static route, o - ODR P - periodic downloaded static route Gateway of last resort is 10.24.95.17 to network 0.0.0.0 10.0.0.0/8 is variably subnetted, 3 subnets, 2 masks 10.24.80.0/24 is directly connected, Cable2/0 10.24.81.0/24 is directly connected, Cable2/0 10.24.95.16/28 is directly connected, FastEthernet0/0 S* 0.0.0.0/0 [1/0] via 10.24.95.17 In the example above, the CMRG was set up to send RIPv2 messages to the CMTS. The CMTS was also set up to receive these messages. 5.4 Firewall Choose Firewall and the submenus of Firewall are shown as below. Figure 26 submenus of Firewall 5.4.1 Basic Choose Firewall > Basic to display the following page. This page is used to block or exclusively allow different types of data through the CMRG from the WAN to the LAN. 30 SR804N Cable Modem User Manual Figure 27 Basic configuration The “low” setting does not block any services/ports, however it does protect against invalid packets and well known attacks. The “medium” setting will cause the firewall to drop a packet unless it is on a specific port of allowed services, The allowed services are listed on the same page. The “high” setting is similar to “medium”, but allows access to even fewer services. The “off” setting allows all traffic to pass. Block Fragmented IP packets prevents all fragmented IP packets from passing through the firewall. Port Scan Detection detects and blocks port scan activity originating on both the LAN and WAN. IP Flood Detection detects and blocks packet floods originating on both the LAN and WAN. The Apply button must be clicked in order to activate any of the checkbox items. All of these settings can be activated on-the-fly without a CMRG reboot. 5.4.2 Local Log Choose Firewall > Local Log to display the following page. 31 SR804N Cable Modem User Manual Figure 28 Local Log The Local Log can send firewall attack reports out in two different ways.

The MAC address of the wireless interface is displayed at the top of the page. Wireless: Allows the wireless interface to be enabled and disabled. Country: Restricts the channel set based on the selected country‟s regulatory requirements. Output Power: Control the range of the AP by adjusting the radio output power. 802.11 Band: Select the radio operates in the 2.4 GHz band. 802.11 n-mode: Switch this to Off to force the AP to operate in 802.11g mode. 802.11 N Support Required: If the 802.11 N support required field is set to “on”, then only .n capable stations are allowed to associate with the CM. If it‟s set to “off” then b/g/n are all allowed. Bandwidth: 802.11b/g channels are only 20 MHz wide, but 802.11n channels may be 40 MHz wide. There are some backward compatibility issues with 40 MHz channels though. These issues are more likely to be encountered in the 2.4 GHz band where legacy (802.11b/g) devices may be operating using 20 MHz channels. Sideband for Control Channel (40 MHz only): Whether the 20 MHz control channel uses the upper or lower half of the 40 MHz channel. Changes to this setting may change the control channel setting. For example (in the 2.4 GHz band), if the upper 20 MHz is selected as the sideband for the control channel, then the lowest control channel available would be channel 5 to allow the lower 20 MHz for data. Control Channel: Selects the control channel for AP operation. The list of available channels depends on the selected country as presented in Table 1. Next to the drop-down list box, the current channel number is displayed. Table 1. Allowed Channels by Country: 39 SR804N Cable Modem User Manual Country First Channel Last Channel USA 11 Worldwide, China, Europe 13 Japan, Thailand, All Channels 14 Israel Jordan 10 13 Regulatory Mode: Selects either 802.11d or 802.11h modes of operation. These are amendments to the 802.11 specifications for solving interference issues with other transmission systems such as satellite or radar, and also transmission requirements in different parts of the world. TPC Mitigation (dB): Transmit Power Control mitigation factor in dB. Transmit Power Control is used to automatically reduce the transmission power when other networks are within range. This setting is only used when the Regulatory Mode is set to 802.11h. OBSS Coexistence: Enable/Disable Overlapping BSS Coexisistence. OBSS coexistence refers to the ability of the AP to support 20 MHz devices within 40 MHz channels. It also allows the AP to better deal with nearby 20 MHz devices that are interfering with part of its 40 MHz channel. STBC Tx: STBC :Space Time Block Code. Switch to on will obtain the full antenna gain. Scan Wireless AP’s: Force the Modems Access Point to scan for other AP‟s within receive range.

Network Name (SSID): Sets the Network Name (also known as SSID) of the primary network. This is a 1-32 ASCII character string. Closed Network: The Network Name is not broadcast by the AP in a Closed Network. Therefore, only clients who already know the network name will be able to connect. WPA: Wi-Fi Protected Access is a slightly older and less secure algorithm for securing a wireless network. This is the Enterprise variant that requires configuration of a RADIUS server. 41 SR804N Cable Modem User Manual WPA-PSK: The Pre-Shared Key mode of the WPA algorithm which does not require use of a RADIUS server. This is also known as WPA Personal. WPA and WPA-PSK cannot be used at the same time. WPA2: An advanced form of WPA that is more secure. This is the Enterprise mode of WPA2 which requires the use of a RADIUS server. WPA2 and WPA may be used at the same time to provide backward compatibility with devices that do not support WPA2. WPA2-PSK: The Pre-Shared Key mode of WPA2, also known as WPA2 Personal. WPA2 and WPA2-PSK cannot be used at the same time. WPA2-PSK and WPA-PSK may be used at the same time to provide backward compatibility with devices that do not support WPA2. WPA/WPA2 Encryption: When using any of the WPA authentication schemes, AES, or TKIP + AES encryption modes can be set. AES provides the strongest encryption, while TKIP provides strong encryption with improved backward compatibility. The TKIP + AES mode allows both TKIP and AES-capable clients to connect. WPA Pre-Shared Key: Sets the WPA Pre-Shared Key (PSK). This is an 8-63 ASCII character string, or a 64-digit hex number. Enabled when the Network Authentication method is WPA-PSK or WPA2-PSK. RADIUS Server: Sets the IP address of the RADIUS server to use for client authentication. The RADIUS server may be on either the public network (WAN) or private network (LAN). This is only for WPA or WPA2 (Enterprise) modes. RADIUS Port: Sets the UDP port number of the RADIUS server. The default is 1812. RADIUS Key: Sets the shared secret for the RADIUS connection. The key is a 0 to 255 character ASCII string. Group Key Rotation Interval: The rotation interval in seconds indicating how often transmission keys should be rotated. Set to zero to disable periodic rekeying. WPA/WPA2 Re-auth Interval: 42 SR804N Cable Modem User Manual This value indicates how often a station using Enterprise security needs to contact the RADIUS server. WEP Encryption: Sets the WEP encryption mode. Both 64-bit and 128-bit WEP encryption modes are supported. When running Shared Key or 802.1x authentication, WEP encryption must be enabled. WEP encryption cannot be used at the same time as WPA or WPA2. Network Key 1 thru Network Key 4: When WEP encryption is enabled, sets the static WEP keys. Enter 5 ASCII characters or 10 hexadecimal digits for a 64-bit key. Enter 13 ASCII characters or 26 hexadecimal digits for a 128-bit key. Current Network Key: When WEP encryption is enabled, selects the encryption (transmit) key. PassPhrase: Sets the text to use for WEP key generation. Generate WEP Keys: When WEP encryption is enabled, this action button converts the passphrase entered to a set of WEP keys. Remember to click the Apply button to save the keys. Automatic Security Configuration Wi-Fi Protected Setup (WPS); WPS is the standard method to achieve the same goal as Broadcom‟s SES.

Most of the configuration points on the guest network page are identical to those on the Primary Network page. A few extras are explained below. DHCP Server: Enables the DHCP server to gives out leases to guest network clients from the specified lease pool. If the DHCP server is disabled, guest network STAs need to be assigned static IP addresses. IP Address: This specifies the gateway IP relayed to guest clients in DHCP lease offers. Subnet Mask: This specifies the subnet mask for the guest network. Lease Pool Start: 44 SR804N Cable Modem User Manual This specifies the starting IP address for the guest network lease pool. Lease Pool End: This specifies the ending IP address for the guest network lease pool. Lease Time: This specifies the lease time for the guest network lease pool, once the CMRG completes WAN provisioning. 5.7.4 Advanced Choose Wireless > Advanced to display the following page. Figure 43 Advanced setting This page allows you to configure advanced wireless settings. 54g™ Mode: Sets the network mode. Choices are 54g Auto, 54g Performance, 54g LRS, and 802.11b Only. 54g Auto accepts 54g, 802.11g, and 802.11b clients, but optimizes performance based on the type of clients connected. 54g Performance accepts only 54g™ clients and provides the highest throughout; nearby 802.11b networks may have degraded performance. 54g LRS interoperates with the widest variety of 54g™, 802.11g, and 802.11b clients. 80211b.accepts only 802.11b clients. 54g™ Protection: 45 SR804N Cable Modem User Manual In Auto mode the AP will use RTS/CTS protection to improve 802.11g performance in mixed 802.11g + 802.11b networks. Turn protection Off to maximize 802.11g throughput under most conditions. Xpress Technology: Enable Broadcom proprietary method of block frame acknowledgement for 802.11g frames. This feature may improve throughput, but may cause problems. Afterburner Technology This feature removes the need for the acknowledgement of data frames. It may improve throughput, but may cause problems. 802.11n Protection: Similar to 54g protection except it applies to 802.11n devices. Basic Rate Set: Determines which rates are advertised as “basic” rates. Default uses the driver defaults. Sets all available rates as basic rates. Multicast Rate: This is the rate at which you send out multicast packets to stations. Multicast packets are not acknowledged. NPHY Rate: Choose 802.11n rate to be applied to all unicast packets. Legacy Rate: “N” mode must be off on the “radio” webpage for this control to be active. When active the user can force the rate in which the AP will operate. Beacon Interval: Sets the beacon interval in milliseconds for the AP. The default is 100, which is fine for nearly all applications. DTIM Interval: Sets the wakeup interval for clients in power-save mode. When a client is running in power save mode, lower values provide higher performance but result in decreased client battery life, while higher values provide lower performance but result in increased client battery life. Fragmentation Threshold: Sets the fragmentation threshold. Packets exceeding this threshold will be fragmented into packets no larger than the threshold before packet transmission. RTS Threshold: 46 SR804N Cable Modem User Manual Sets the RTS threshold. Packets exceeding this threshold will cause the AP to perform an RTS/CTS exchange to reserve the wireless medium before packet transmission. 5.7.5 Access Control Choose Wireless > Access Control to display the following page.
