WLP Safety Information RF Exposure The WLP, an outdoor access point, is compliant with the requirements set forth in CFR 47 section 1.1307, addressing RF Exposure from radio frequency devices as defined in OET Bulletin 65. The outdoor access point antennas should be installed to provide a separation distance of at least 3 feet (1 meter) from humans. WLP Lightning Protector A lightning protector is required when the WLP unit is installed in an outdoor location and the Ethernet cable connects to an indoor network device. The purpose of the lightning protection is to protect people and equipment located indoors from lightning that might strike the WLP or its outdoor cables. Therefore, the lightning protector device should be installed indoors, as close as possible to the point where the cables enter the building. The lightning protector can also be installed outdoors, as long as the cables that go from the lightning protector to the indoors are well protected from lightning between the box and the building entrance. Verify that you have shared grounding. GO Networks offers a lightning protector that can be ordered separately.

Information de sécurité pour WLP Exposition aux fréquences RF Le point d’accès extérieur WLP est compatible avec la norme CFR 47 section 1.1307 concernant l’exposition aux appareils émetteurs de fréquences radio RF définis par le Bulletin 65 de l’OET. Les antennes doivent être installées à une distance minimum d’un mètre de personnes humaines. Paratonerre pour WLP Un paratonnerre est nécessaire lorsque le point d’accès WLP est installe à l’extérieur et lié à un network intérieur par un câble Ethernet. La fonction du paratonnerre est de protéger les personnes et équipement situés en intérieur des éclairs qui pourraient frapper le WLP ou son câble extérieur. Par conséquent, le paratonnerre doit être installé en intérieur le plus près possible du point où le câble de liaison pénètre le bâtiment. Le paratonnerre peut aussi être installé en extérieur à la condition que les câbles a l’intérieur du bâtiment soient protégés des éclairs entre le point d‘accès et l’entrée du bâtiment Vérifier que la prise de terre est partagée. GO Networks met a disposition à la vente un paratonnerre.

Performing a Site Survey 2. Assembling and Mounting 3. Mounting the WLP unit 4. Connecting the Antennas 5. Connecting the cables 6. Powering up the unit and configuring the software 7. Performing a Post-installation Testing Procedure to verify connectivity and operation Site Survey Most wireless LANs include many access points installed in various locations in an overlapping radio-cell pattern. It is important to carefully identify each access point’s position and the assignment of its radio channels. Therefore, a site survey becomes an essential first step before physically deploying the GO MBW WLP Pico Cellular Base Station solution. Installation of the access points requires a backhaul to interface the corporate network or Internet. This backhaul connection can be a mesh configuration, an Ethernet-wired connection, or a third-party solution. When using any method other then a wired connection, keep in mind the WLP has to have a good reception on its BH side so it will not limit the access-channel performance. Conclude the site survey with a detailed plan of the MBW system deployment. The system deployment plan should include WLP mounting points and the routes for the power and backhaul cables. Note: When mounting the WLP on a pole (or wall mount), the pole should be able to support four times the weight of the WLP, as well as the wind loading created by the WLP. Since the mounting structure itself is a potential source of interference, the cell should be mounted with at least 4 feet of clearance between the antennas and the mounting structure.

Following is a diagram explaining how the Ethernet cable should be assembled prior to connecting it to the WLP unit: Figure 10: Ethernet Cable Connector Power Connection The WLP unit can be connected to an AC power source by one of several methods. It can be connected directly to a power source or by using an adapter to connect to the streetlight photocell (photo-control). The WLP unit can support input voltage of 100 to 240 VAC (50 to 60 Hz). Note: Connect the grounding cable before connecting any other cables. When removing the WLP, the grounding cable should be the last cable removed. Noter: Connecter la prise de terre 10 AWG avant de connecter tout autre câble. Pendant la désinstallation du WLP, la prise de terre doit être le dernier câble retiré. To connect the AC power to the WLP via the streetlight photocell: 1. Check the input voltage to the streetlight photocell. The voltage must be between 100 to 240 VAC. If yes, continue with this procedure. Otherwise, use a different method for the power connection. 2. Remove the streetlight photocell. Turn the photocell counterclockwise and lift the photocell out of the socket. 3. Insert the Auxiliary Power Adapter in the socket of the photocell. Note that one prong is larger than the other two. Align the larger prong on the adapter with the larger slot in the socket. Insert the Auxiliary Power Adapter into the socket and rotate the adapter clockwise.

Power Up and Software Configuration The WLP unit is normally mounted on a streetlight (pole or wall) where it is inconvenient to configure. Therefore, it is recommended that wireless communication be established to the unit prior to installation, so that the unit can later be configured and monitored from the ground. To verify communications when installing the WLP unit, the Mesh-Gateways must be installed and powered up first. The LEDs on the WLP unit indicate the status of communications between the WLP unit and the network. See Table 6 for more information on the LED indicators. The ACT LED on the Mesh-Gateway should be checked to verify that wired communications have been established. The BH LED on the Mesh-Gateway should be checked to verify that wireless communications have been established. When powering up a Mesh-Node, the BH LED should be lit to verify that the WLP unit’s wireless communication is connected. WLP boot time is about 2.5 minutes. The BH LED indicator will light up after the boot is completed. LED Function PWR Green – There is power to the unit. Unlit – There is no power to the unit. STAT Green – The operational status of the WLP unit is normal. Red – The WLP unit is in a failure state. Unlit – There is no power to the unit. ACT Green – When the LED is on, there is a communication connection. When the LED is flashing, traffic is flowing though the WLP unit. Unlit – There is no communication connection. BH Green – On a Mesh-Gateway, the mesh functionality is activated. On a Mesh-Node, the WLP is connected to the mesh. Unlit – On a Mesh-Gateway, the mesh functionality is not activated or no Ethernet link is available. On a Mesh-Node, the WLP is not configured or failed to connect to the mesh.

Configuring the WLP Following is a brief overview of the main CLI commands that are used to configure the WLP. A configuration example follows the detailed list of configuration commands. These and other CLI commands are detailed in the GO MBW CLI Reference Guide. Connect and Access the WLP Initial configuration of the WLP is done using a serial cable. A standard RS232-interface DB-9 cable is connected to the COM port of a laptop or a PC to the WLP unit’s console port. For more information regarding the serial cable, see Appendix B, Wiring Specifications. Once the WLP IP address is configured, the rest of the configuration can be done using Telnet via the network. Figure 12: Connect and Access the WLP Notebook PC Consol Port: Consol Port: RS232 WLPRS232
- Page 21 of 38 - All contents are Copyright © 2006 GO Networks, Inc. All rights reserved. Once the cable is connected, you can then operate a terminal program, such as HyperTerminal. The PC port should be configured as follows:  Baud rate = 9600  Data bits = 8  Parity = none  Stop bits = 1  Flow control = None Note: New laptops may not include an RS-232 serial port. If a serial port is not available, you may use a USB to serial converter. To use HyperTerminal: From the Start menu: 1. Select All Programs > Accessories > Communications > HyperTerminal. 2. Define a new connection. 3. Right-click and select Properties. Set or verify the above values. 4. Click OK. Figure 13: HyperTerminal Configuration 5. Establish the connection between the WLP and the laptop (or PC). 6. Log in using the predefined “super” user (user: super; password: super). The user name determines the authorization level and determines whether the operator can view configuration and operation parameters, or implement changes. A new user and password name should be added.
- Page 22 of 38 - All contents are Copyright © 2006 GO Networks, Inc. All rights reserved. However, the default name and password can be used for the initial configuration. The default system prompt is set to go. Configuring the Management Connectivity Configuring the management connectivity involves setting the device IP address, IP mask, management VLAN and default gateway. These procedures are detailed in the following sections. Assigning management IP and VLAN Define the static IP address, subnet mask and the management VLAN on the same network through which you connect to the WLP. You can use the CLI command: configure ip vlan {<vlan number> | none} {<address ipaddress> [<mask ipaddress>] | dhcp} The default IP address is 192.168.0.10 with no VLAN tagging. Example: To assign a management IP and VLAN, where: Management IP Address = 192.168.30.102 Management IP Subnet Mask = 255.255.255.0 VLAN ID = 0 with no VLAN tagging specify: configure ip vlan none 192.168.30.102 255.255.255.0 If the IP address is to be obtained from a DHCP server, the management IP address and subnet mask is not specified. Example: To define that the management IP is to be obtained from a DHCP server, where: VLAN ID = 100 specify: configure ip vlan 100 dhcp
- Page 23 of 38 - All contents are Copyright © 2006 GO Networks, Inc. All rights reserved. Default Gateway Define the default gateway by using the Configure mode (consult with your network administrator). You can use the CLI command: configure ip default-gateway {<ip ipaddress> | disable} Example: To define the default gateway, where: Default Gateway IP Address = 192.168.30.254 specify: configure ip default-gateway 192.168.30.254 Note: If you are using DHCP client on the first gateway, you do not need to configure the default gateway. Configuring the Device Prompt By default the device prompt is set to “go”. However, configuring a unique device prompt is very useful for the operator. A unique device name allows the operator to quickly identify to what device he is logged in. The WLP prompt can be defined using the following CLI command: hostname set <prompt string> Configuring the Radio Settings Setting the Radio Frequency The Radio interface frequency is configured by using the following CLI command: configure interface {Dot11Radio | BHRadio} <interface number> channel <channel number> Setting the Radio Data Rates By default, the 802.11b/g channel is defined for use in a mixed mode. You can select a rate per channel for one of two states: g or mixed (a combination of g and b). The following CLI command syntax is used: configure interface Dot11Radio <interface number> mode {g | mixed}
- Page 24 of 38 - All contents are Copyright © 2006 GO Networks, Inc. All rights reserved. Setting the Radio Sensitivity The range and capacity of the WLP device is highly dependent upon its RX sensitivity. RX sensitivity is measured in dBm. A large negative number (as example -101dBm) is considered high sensitivity, while a smaller number (as example -90dBm) is considered low sensitivity. A high sensitivity will result in an increased range along with higher susceptibility to noise/interference. The higher noise susceptibility will result in lower throughputs. A low sensitivity will result in a reduced range with lower susceptibility to noise. The lower noise susceptibility will result in higher throughputs. Clearly, when setting the device sensitivity the user has to compromise range verses capacity. The amount of noise in the system can be monitored by the Viewer or by the following CLI command: show interface wifi-load-ratio Figure 14 displays a printout of the wifi-load-radio command. In this example on the Dot11Radio the air is currently occupied at 15% of the time. Out of these 15%, 1% was used to transmit WLAN packets and 8% of the time was used to receive packets. Note that packets are received from all WLAN devices at your current frequency. Therefore, a large amount of the RX air time might be taken by neighboring networks. The remaining 6% (i.e. 15-8-1=6) is the amount of air time occupied by non-WLAN signals. These 6% are what we call noise. go> show interface wifi-load-ratio ------------------------------------------------------------------------------- |Interface Name |Clear Count Ratio |Rx Frame Count |Tx Frame Count |--------------------|--------------------|--------------------|--------------- |Dot11Radio0 |15 |8 |1 |....................|....................|....................|............... |BHRadio0 |12 |9 |3 ------------------------------------------------------------------------------- go> Figure 14: WiFi Load Printout By default, the 802.11b/g channel is set to automatically adjust the interface sensitivity to the noise level in the air. Noise levels of up to 15% are considered normal. If the amount of noise exceeded this level, you should consider changing a channel or lowering the sensitivity.
- Page 25 of 38 - All contents are Copyright © 2006 GO Networks, Inc. All rights reserved. The following CLI command sets the sensitivity level to automatic: configure interface Dot11Radio <interface number> sensitivity auto The current sensitivity level can be monitored using: show interface wifi-stats The sensitivity could also be set manually to support local optimization by an operator. The sensitivity level can be set from –101dBm to –77dBm. The following CLI command sets a static sensitivity level: configure interface Dot11Radio <interface number> sensitivity <level number> Setting the Radio Reception Level The Radio can be configured to reject clients that are below a defined signal level. By default, the Radio Reception Level is set to -103dBm. This results with all clients being accepted, as -103dBm is higher than the maximum sensitivity. The reception level can be set from –103dBm to -50dBm. Setting the reception level can be done using the following CLI command: configure interface Dot11Radio <interface number> reception-level <level number> Access Radio WDS Configuration The Access radio can be configured to support access and/or WDS services. To use the WDS protocol or enable the mesh over the access radio, the Access radio service must be set to support backhaul, or mixed services. By default, the Access radio service is set to support both services. To configure the services supported using the following CLI command: configure interface Dot11Radio <interface number> service {access | backhaul | both} Configuring Multiple SSIDs The SSID is a unique identifier that wireless networking devices use to establish and maintain wireless connectivity. Multiple access points on a network or sub-network can use the same SSID. Configuring the same SSID across multiple APs will enable the users to roam between them seamlessly. SSID names are case sensitive and can contain up to 32 alphanumeric characters. The WLP unit can support up to 16 SSIDs. Each radio interface must be configured with a minimum of one SSID that is defined as a BSSID. Each SSID has its unique privacy configuration and unique VLAN ID. VLAN-ID 0 represents no VLAN tag.
- Page 26 of 38 - All contents are Copyright © 2006 GO Networks, Inc. All rights reserved. Each SSID can be defined as either a Broadcast SSID (BSSID) or a hidden one. Passive scanning clients will not detect a hidden SSID, since it doesn’t transmit any beacon frames. Configuring multiple BSSIDs on the same interface is known as creating a Virtual Access Point. A Virtual Access Point is a logical entity that exists within a physical access point. When a single Physical AP supports multiple Virtual APs, each Virtual AP appears to stations to be an independent Physical AP, even though only a single Physical AP is present. Note: SSIDs, VLANs, and encryption schemes are mapped together on a one-to-one-to-one basis. One SSID can be mapped to one VLAN, and one VLAN can be mapped to one encryption scheme. Define the SSID parameters. This configuration stage is common to SSID to be used as primary (broadcast) or hidden. In the following example, three SSID’s are defined as GO-WLP1, GO-WLP2, and GO-HIDDEN, each with its own VLAN-ID, and no privacy. go> /configure ssid 1 name GO-WLP1 vlan 0 privacy-method none type bssid go> /configure ssid 2 name GO-WLP2 vlan 100 privacy-method none type bssid go> /configure ssid 3 name GO-HIDDEN vlan 200 privacy-method none type hidden The next step in the configuration is to attach the defined SSIDs to the interface: go> /configure interface dot11Radio 0 ssid add 1 go> /configure interface dot11Radio 0 ssid add 2 go> /configure interface dot11Radio 0 ssid add 3 Deleting an SSID To delete an SSID, the SSID must first be removed from the interface. After the SSID is removed, then the SSID can be deleted. The following example demonstrates the deletion of SSID 3 from interface dot11Radio 0. To remove an SSID from the interface: go> configure interface dot11Radio 0 ssid remove 3 To delete an SSID: go> configure ssid 3 remove Configuring the Mesh Network The WLP mesh network is based upon WDS (Wireless Distribution System) protocol. WDS is used to support wireless backhauling and meshing between WLP and CPE units. WDS supports backhauling over both the 2.4 GHz access radio and the 5 GHz backhaul radio.
- Page 27 of 38 - All contents are Copyright © 2006 GO Networks, Inc. All rights reserved. The mesh topology is based on a tree structure as illustrated in Figure 15. At the top of each tree is a WLP unit that is functioning as a Mesh-Gateway, which is connected to the backbone network through its wired port. All other WLP units in the tree are functioning as Mesh-Nodes. Each Mesh-Node is wirelessly connected to a WLP unit creating a backhaul mesh that leads to a Mesh-Gateway. The WMG and third party CPEs connect at the bottom of the tree. The clients communicate with the WLP units on the access radio. Mesh-Node Mesh-Node DomainDomainMesh-Node Mesh-Gateway ClientClientClient ClientClient Mesh-Gateway WMGClient Figure 15: WDS Mesh Network Mesh network routing is automatic, therefore when more then one route exists, the WLP will route the traffic using the best route. In a similar way, the mesh will recover from a fault by selecting an alternate route when required.
- Page 28 of 38 - All contents are Copyright © 2006 GO Networks, Inc. All rights reserved. The Mesh-Gateway is the only WLP unit connected to the wired LAN. All other WLP units are Mesh-Nodes and they depend on the WDS mesh network for backhaul connectivity. A Mesh-Node determines various routes to the Mesh-Gateway and selects the route with the best connectivity. If you want to limit the automatic route selection made by the mesh, you can manually restrict the selection by defining and implementing a mesh filter list. Configuring a mesh network, all Mesh-Gateways must be assigned a channel. Mesh-Gateways that are close to each other should be assigned a different channel to minimize interference. Mesh-Nodes scan all available channels and select the channel that offers the best connectivity to the mesh network. For more information on assigning a channel, see Configuring the Radio Settings. It is important to note that the number and quality of hops will determine the network performance. In most cases, the physical deployment of the devices is the limiting factor in route selection. By default, the unit is configured as a Mesh-Node, were the BHRadio interface is defined to participate in the mesh network. Mesh Mode Configuration All WLP units connected to the wired Ethernet must be configured as a Mesh-Gateway. To configure the WLP use the following CLI command: configure mesh mode {gateway | node} and specify: configure mesh mode gateway All WLP units that operate as a Mesh-Node are not connected to a wired Ethernet. They are connected to the network with a wireless connection though other WLP or WLS devices. To set the mesh mode accordingly, specify the following CLI command: configure mesh mode node Mesh Network Name All WLP units connected to the same mesh network must be configured with the same network name (ID). Configuring different networks names may be used to create a number of independent networks. By default the network ID is configured as “wds-public”. To set the network ID use the following CLI command: configure mesh network-id <network-id>
- Page 29 of 38 - All contents are Copyright © 2006 GO Networks, Inc. All rights reserved. Example: To define a network ID, where: Network ID = MyMeshNetwork specify: configure mesh network-id MyMeshNetwork Radio Interface Mesh Configuration The user must configure one radio interface on each WLP to participate in the mesh network. By default, the BHRadio interface is defined to participate in the mesh network. Only one interface on each WLP can be defined to participate at one time. All devices in the mesh network must use the same type of interface to communicate with each other. To configure an interface to participate in the Mesh use the following CLI command: configure mesh interface {Dot11Radio | BHRadio} 0 enable Note: To enable the Dot11Radio interface to participate in the mesh network, the service type must be properly configured for the interface. For more information, see Access Radio WDS Configuration. Mesh Security Configuring the Mesh privacy can protect the connections in the mesh network. All the WLP units in the network must be configured with the identical network name and privacy settings. The mesh network can use either WEP or AES encryption protocols. Mesh security is configured or removed by using one of the following CLI commands: configure mesh privacy none configure mesh privacy wep key {40 | 104} <key hex> configure mesh privacy AES passphrase <passphrase string> Example 1: To define the WEP security, where: WEP Key Length = 40 bit WEP Key = 11:22:33:44:55 specify: configure mesh privacy wep key 40 11:22:33:44:55 Example 2: To define the AES security, where:
- Page 30 of 38 - All contents are Copyright © 2006 GO Networks, Inc. All rights reserved. AES Passphrase String = secretkey specify: configure mesh privacy AES passphrase secretkey Displaying Mesh Configuration To display the current mesh configuration of the WLP, use the following CLI command: show mesh params The mesh configuration displays the mesh timeout, mesh interface, mesh security settings and whether the unit has been defined as a Mesh-Gateway or Mesh-Node. Displaying Mesh Routing The mesh routing table contains the routing entry for the current next hop to get access to the Mesh-Gateway. It also displays all the alternative next hop routing entries. To display the current mesh routing table for the WLP, use the following CLI command: show mesh route Configuring WDS CPE connection The WDS protocol can be used to connect with CPE devices. To configure the WDS connection manually, use the following CLI command: configure interface {Dot11Radio | BHRadio} <interface number> wds-peer {add | remove} <address macaddress> The MAC address is the MAC address of the CPE unit. Note: Caution should be used when configuring the WDS connection manually. Improper configuration can result with network loops. Example: To connect to a CPE device manually, where: Radio Interface = BHRadio CPE MAC Address = 00:14:06:11:00:00 specify: configure interface BHRadio 0 wds-peer add 00:14:06:11:00:00

Configuring Authentication Types In the most common 802.1X WLAN environments, the WLP units defer to the Radius server to authenticate users and to support particular EAP authentication types. The Radius server handles these functions, and provides crucial authentication and data-protection capabilities according to the requirements of the EAP authentication type in use. The Radius client runs on the WLP device and sends authentication requests to a central Radius server, which contains all user authentication and network service access information. The Radius server is normally a multi-user system running Radius server software (such as developed by Microsoft or other software vendors). The wireless client device and Radius server on the wired LAN use 802.1x and EAP to perform mutual authentication through the WLP. 1. The Radius server sends an authentication challenge to the client. 2. The client uses a one-way encryption of the user-supplied password to generate a response to the challenge and sends that response to the Radius server. 3. The Radius server receives the encryption response from the client and compares the response to the information stored in its database. When the Radius server authenticates the client, the process repeats in reverse, and the client authenticates the Radius server. Configuring the Radius Client in the WLP Your WLP must be configured to support the Radius server communication. At a minimum, you must identify the Radius server software and define the method lists for Radius authentication. Alternatively, you can define method lists for Radius authorization and accounting. Identifying the Radius Server WLP-to-Radius server communication involves several components: • IP address • Authentication destination port • Accounting destination port • Key string You should identify the Radius security server’s IP address and specific UDP port numbers. The combination of the IP address and the UDP port number creates a unique identifier. A Radius server and the access point use a shared secret text (key) string to encrypt passwords and exchange responses.
- Page 32 of 38 - All contents are Copyright © 2006 GO Networks, Inc. All rights reserved. The Radius client in the WLP can be configured by using the following command: configure radius-server {primary | secondary} {authentication | accounting} <port 1 – 65535> host <ip address> key <secret 5 – 64 string> enable Configuring Privacy Methods The privacy (encryption) scheme is configured per ESSID. Using WPA Key Management WiFi Protected Access (WPA) is a standards-based, interoperable security enhancement that strongly increases the level of data protection and access control for existing and future wireless LAN systems. It is derived from and will be forward-compatible with the upcoming IEEE 802.11i standard. It includes two new data-confidentiality protocols (TKIP and AES-CCMP). WPA leverages TKIP and AES-CCMP (Temporal Key Integrity Protocol and Cipher Block Chaining Message Authentication Code Protocol) for data protection and 802.1X for authenticated key management. WPA1 and WPA2 offer a high level of assurance for end users and network administrators that their data will remain private and that access to their networks will be restricted to authorized users. WPA key management supports two mutually exclusive management types: • WPA-Extensible-Authentication-Protocol (WPA-EAP): Using WPA-EAP key management, the client and the authentication server authenticate each other using an EAP authentication method, and the client and server generate a Pairwise Master Key (PMK). • WPA-Pre-shared key (WPA-PSK): Using WPA, the server generates the PMK dynamically and passes it to the WLP. Using WPA-PSK, however, you configure a pre-shared key on both the client and the WLP, and that pre-shared key is used as the PMK. The WPA key management in the WLP can be configured using the following commands: configure privacy wpa { <ssid integer(1-16)> [ passphrase <passphrase string(8-63)> ] [ key-mngmnt { eap | psk } ] configure privacy wpa gtk-interval <interval integer(30-42949672)> configure privacy wpa data-encryption { tkip | aes } configure privacy wpa protocol { wpa1 | wpa2 | wpa2only } configure privacy wpa preauthentication { enable | disable }
- Page 33 of 38 - All contents are Copyright © 2006 GO Networks, Inc. All rights reserved. For example, configuring SSID 1 with a pass phrase of 12345678: /configure privacy wpa 1 key-mngmnt psk passphrase 12345678 /configure privacy wpa protocol wpa1 /configure privacy wpa data-encryption tkip /configure privacy wpa gtk-interval 72000 /configure privacy wpa preauthentication disable Saving the Configuration Once you have modified the existing configuration file, save the file for future use. To do this, issue the following CLI command: copy running-configure startup-configure WLP Configuration Example The following example assumes that you are configuring a WLP from its default configuration using the serial port. If the WLP device is configured from the Ethernet, Dot11Radio or BHRadio, issuing any one of the following commands could disconnect the user: • Changing the IP address • Changing the SSID or WDS configuration ##### configure management ip #### go> /configure ip vlan none 192.168.30.102 255.255.255.0 go> /configure ip default-gateway 192.168.30.254 #### remove default bssid configuration #### go> /configure interface Dot11Radio 0 ssid remove 1 go> /configure ssid 1 remove #### configure a new bssid #### go> /configure ssid 1 name MY-SSID vlan 0 privacy-method none type bssid go> /configure interface Dot11Radio 0 ssid add 1 #### mesh gateway configuration #### go> /configure mesh mode gateway go> /configure mesh network-id MyMeshNet go> /configure mesh privacy AES passprash MyMeshKey #### set channels and enable the radios ### go> /configure interface Dot11Radio 0 channel 1 go> /configure interface Dot11radio 0 enable go> /configure interface BHRadio 0 channel 157 go> /configure interface BHRadio 0 enable #### save configuration #### go> /copy running-config startup-config

A software upgrade can be performed by connecting to the Ethernet port or over the air connected through the access or BH radios. When a software upgrade is performed, a new image is copied to the WLP Flash (ROM memory). The Flash holds two software images. Therefore, when a new image is uploaded, the running image is not overridden. If, for any reason, the software upgrade fails, the WLP can continue to function with its current image. Obtaining a New Software Image New software images can be downloaded from the GO Networks FTP site using the following connection information: ftp://versions:ver2go@ftp.gonetworks.com Username: versions Password: ver2go The software images are under the WLS directory. Note that the images are named WLS, as WLS and WLP devices are loaded with the same software image. TFTP Software Upgrade To upgrade software using TFTP, the user has to prepare a TFTP server with the new software image. A freeware TFTP server such as PumpKIN can be downloaded from the Internet and installed on the technician’s PC. To upgrade the software via TFTP use the following command: import image from tftp <ip address> <filename>
