Refer to Chapter 4 for information on how to run the wizard. LAN Settings Unit Configuration The LAN Settings menu provides the following options: Figure 32 Unit Configuration Screen LAN Settings 49 The LAN Settings screen is used to specify the LAN IP address of your Router, and to configure the DHCP server. 1 Select Unit Configuration and then specify the Router IP Address and Subnet Mask in the LAN Settings section. The default IP address of the Router is 192.168.1.1. 2 If you want to use the Router as a DHCP Server, check the Enable check box. 3 Clicking Auto Range will automatically choose the largest available range of addresses for your network. Alternatively, you can change the address range by changing the last digit(s) of the IP Pool Start Address, or the IP Pool End Address, or both. 4 If you use 3Com NBX telephones, enter the IP address of the NBX call processor at 3Com NBX Call Processor. 5 Check all of your settings, and then click Apply. The DHCP server will give out addresses to both wired and wireless clients. Static DHCP Assignment Figure 33 Static DHCP Assignment Screen DHCP Clients List Click on the DHCP Client Tab to display a list of all the DHCP clients in your network. 50 CHAPTER 5: ROUTER CONFIGURATION Wireless Settings The Wireless Settings menu provides options described in the following sections. To improve the security of your wireless network, 3 Com recommends that you: 1.Change the SSID from its default value 2.Enable Encryption 3.Enable Connection Control LAN Settings 51 Configuration Figure 34 Configuration Screen Enable Wireless Networking Use this check box to enable or disable the wireless secion of your LAN. When disabled, no wireless PCs can gain access to either the internet or other PCs on your Wired or Wireless LAN through this Router. Channel Selection Select a number from the drip-down list to specify which Channel the Router will transmit and receive on. If another access point or Router nearby is using the same Channel as you, there will be a reduction in the performance of your network. If this seems to be the case, you should select a different channel number. Usually the Wireless computers will scan to find the correct channel, but if they don't you must configure them to use the same Channel number as the Router. Choose the Clear Channel Select option to automatically choose the clearest channel. The Router will check for the clearest channel whenever it is rebooted, powered up, and when the Clear Channel Select option is first applied. Valid channels are country dependent. 52 CHAPTER 5: ROUTER CONFIGURATION Service Area Name/SSID This allows you to name your Wireless network. The Service Area Name/SSID field will accept any alphanumeric string and has a maximum length of 32 characters. Your Wireless computers must be configured with exactly the same name or you will not establish a connection. The Service Area Name may also be referred to as "ESSID" depending on your networking vendor. By default the Router uses the name "3Com". 3Com recommends that you change the default name. In order that your wireless computers can connect to the Router, you must: Use Infrastructure Mode not Ad hoc Mode Have the same Service Area Name as the Router. Have the same Channel number as the Router. Use the same encryption type and keys as the Router. Ensure that the PC is included in the aouthorized Wireless PCs list if Connection Control is enabled. Enable Broadcase SSID Disable this feature after you have installed your wireless network to improve the security of your network. When the check box is checked, the Router will broadcast the Service Area Name/SSID of your wireless network, whick reduces the security of your Router as it allows any wireless client to see your wireless LAN. If you have a wireless client that can detect all the available SSIDs in your area, your client will not list the Router SSID unless this feature is enabled. THe clients will still be able to connect, provided that they are supplied with the SSID. 3Com recommends that you install your wireless network with this feature enabled and than disable it once you have set up the Router and wireless clients. SSID If required, enter a name that you want to use to uniquely identify the device at the SSID prompt. LAN Settings 53 Encryption When setting up wireless networks, it is important to remember that with encryption disabled, anyone with a Wireless PC can eavesdrop on your network. 3Com recommends that you get the network working with encryption disabled first and then enable it as the last step. This will simplify setting up your network. You can configure wireless security such as WEP or WPA encryption on this screen. Note: it is recommended that you use WPA encryption over WEP if your wireless clients support WPA All of the wireless clients must use the same security settings in order to connecdt to the router. WPA -- Wi-Fi Protected Access (WPA) is a 256 bit encryption method with keys that change over time. WEP -- Wireless Equivalent Privacy (WEP) is a 64 bit or 128 bit encryption method with user configurable fixed keys. WPA provides a higher level of security, provided by its longer key and dynamic changes made to the key over time. 3Com recommends that you use WPA with any clients which support it. If you enable encryption on the Router, you must reconfigure your wireless PCs to use exactly the same Encryption Type and Keys otherwise the devices will not understand each other. The encryption methods used by the Router secure data transmitted through wireless communications between the Router and its wireless clients. Enabling encryption has no security effect on data transmitted through wired (Ethernet) connections or through your connections to the Internet. 54 CHAPTER 5: ROUTER CONFIGURATION WEP To enable WEP, select WEP from the Security Mode. Encryption: Choose from 64 bits or 128 bits Passphrase:You can enter a passphrase and click on the Generate button and the router will automatically generate four WEP keys for you. WEP Key1-4:Manaually assign a passphrase for each key. If you selected 64 bits encryption, enter 10 HEX characters (0-F) for each key. If you selected 128 bits encrtpyion,enter 26 HEX characters (0-F) for each key. TX Key:Select a key to be the active key. Click Save to save the setting
