MG7540 Cable Modem User Manual 7 4 PC Network Configuration and Login 4.1 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. MG7540 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 7.

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 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
MG7540 Cable Modem User Manual 32 7223#term mon The CMTS is now configured to accept RIPv2 messages. If the CM/RG 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 CM/RG 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).

MG7540 Cable Modem User Manual 37 WPS Enable/Disable: WPS stands for Wi-Fi Protected Setup. WPS provides two methods to automatically distribute wireless keys to clients that support this feature, described below. For the record, as of July, 2015, Apple devices did not support WPS. WPS Client PIN Method: On your client device, run a utility to generate a WPS PIN. Copy the PIN that the client generates and enter it here, then press the Save button. Once this process is complete, your cable modem/router will display the results, or it will time out after about two minutes. Note that this method will change the default SSID and key for your network. 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. 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. Encryption: Select the desired encryption protocol for your network. The default is TKIP+AES. RADIUS: Disable WPA-PSK / WPA2-PSK and Enable WPA / WPA2 to un-gray out RADIUS settings.

MG7540 Cable Modem User Manual 43 OBSS Coexistence: OBSS coexistence refers to the ability of your device to support 20 MHz clients within 40 MHz channels. It also allows your device to reduce interference from nearby 20 MHz devices that are interfering with part of your device's 40 MHz channel. Hide SSID (Closed Network): When this feature is enabled, the SSID is not broadcast. Therefore, only devices that already know the SSID will be able to connect. Mode Required: Select None, HT or ERP, where HT and ERP refer to High Throughput and Extended Rate PHY, respectively. These settings determine how your network interacts with older (802.11b/g) and newer (802.11n) wireless clients. Most users will leave this at the default setting of None. Isolate Client: When this feature is enabled, wireless clients are isolated from your wired network and from each other. They can only access the Internet, but not any servers or other devices on your network. 54g™ Mode: Sets the network mode for legacy 802.11g & 802.11b networks. To un-gray out this selection, under the 2.4GHz tab in WPS_RADIUS_WEP, Disable 802.11n Mode. Choices are 54g Auto, 54g only, 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. 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.
MG7540 Cable Modem User Manual 44 802.11n Protection: 802.11n Protection protects legacy 802.11b&g devices that are within range of your cable modem/router. This feature is enabled (Auto) by default. In some environments with no legacy devices, you may improve performance by disabling this feature. 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: 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.

MG7540 Cable Modem User Manual 46 Figure 33 WMM configuration This page allows you to configure WiFi Multi-Media (WMM). WMM is an implementation of Quality of Service (Qos) which is defined by the IEEE standard 802.11e. WMM Support: Sets WMM support. Choices are Auto, On, or Off. If enabled (Auto or On), the WME Information Element is included in beacon frame. No-Acknowledgement: Sets No-Acknowledgement support. Choices are On or Off. When enabled, acknowledgments for data are not transmitted. Power Save Support: Sets Power Save support. Choices are On or Off. When Power Save is enabled, the AP queues packets for STAs that are in power-save mode. Queued packets are transmitted when the STA notifies AP that it has left power-save mode. EDCA AP Parameters: Specifies the transmit parameters for traffic transmitted from the AP to the STA for the four Access Categories: Best Effort (AC_BE), Background (AC_BK), Video (AC_VI), and Voice (AC_VO). Transmit parameters include Contention Window (CWmin and CWmax), Arbitration Inter Frame Spacing Number (AIFSN), and Transmit Opportunity Limit (TXOP Limit). There are also two AP-specific settings: Admission Control and Discard Oldest First. Admission control specifies if admission control is enforced for the Access Categories. Discard Oldest First specifies the discard policy for the queues. On discards the oldest first; Off discards the newest first. EDCA STA Parameters: Specifies the transmit parameters for traffic transmitted from the STA to the AP for the four Access Categories: Best Effort (AC_BE), Background (AC_BK), Video (AC_VI), and Voice (AC_VO). Transmit parameters include Contention Window (CWmin and CWmax), Arbitration Inter Frame Spacing Number (AIFSN), and Transmit Opportunity Limit (TXOP Limit).
