Advanced Configuration Routing Overview • If you don't have other Routers or Gateways on your LAN, you can ignore the "Routing" page completely. • If the UniGateway EH-2101W is only acting as a Gateway for the local LAN segment, ignore the "Routing" page even if your LAN has other Routers. • If your LAN has a standard Router (e.g. Cisco) on your LAN, and the UniGateway EH2101W is to act as a Gateway for all LAN segments, enable RIP (Routing Information Protocol) and ignore the Static Routing table.
Figure 43: Routing Screen Data - Routing Screen RIP Enable RIP Check this to enable the RIP (Routing Information Protocol) feature of the UniGateway EH-2101W.

Appendix A Troubleshooting A This Appendix covers the most likely problems and their solutions. Overview This chapter covers some common problems that may be encountered while using the UniGateway EH-2101W and some possible solutions to them. If you follow the suggested steps and the UniGateway EH-2101W still does not function properly, contact your dealer for further advice. General Problems Problem 1: Can't connect to the UniGateway EH-2101W to configure it.
Problem 2: Some applications do not run properly when using the UniGateway. Solution 2: The UniGateway EH-2101W processes the data passing through it, so it is not transparent. Use the Special Applications feature to allow the use of Internet applications which do not function correctly. If this does solve the problem you can use the DMZ function. This should work with almost every application, but: • It is a security risk, since the firewall is disabled. • Only one (1) PC can use this feature.
Appendix A - Troubleshooting Printing Problem 1: When I tried to install the Printing software for Peer-to-Peer printing, I received an error message and the installation was aborted.. Solution 1: This may be caused by an existing installation of the printer port software. Before attempting another installation: • Remove the existing installation • Restart your PC To remove an existing printer port installation: 1. Open Start - Settings - Control Panel - Add/Remove Programs 2.
7. Click the Add Port button. On the resulting screen, select Other, then Shared Port, as the port to add, as shown below. 8. Click OK to see the Print Port Configuration screen, as shown below.
Appendix A - Troubleshooting 9. Click the Browse Device button, select the desired Broadband Wireless Gateway, and click OK. 10. Click OK to return to the Printers folders, and right-click on the Printer. Ensure that the Work off-line option is NOT checked. The Printer should no longer be grayed out, and is ready for use. Problem 3: On my Macintosh, I can't find the printer connected to the UniGateway EH-2101W..
Dial-in Access Problem 1: Remote PC can't connect to the UniGateway EH-2101W. Solution 1: Check the settings on the UniGateway EH-2101W • Dial-in is Enabled. • User has been created, and has Dial-in permission. • Call-back settings are correct for this user. • Modem settings are correct. • Both the UniGateway EH-2101W and the remote PC are using the same settings for the login authentication (PAP, CHAP, MSCHAP). Check the Modem • Modem is properly connected and powered on.
Appendix A - Troubleshooting Server is Disabled. In this situation, the DHCP Server must still allocate an IP Address to the Dial-in user. To set this IP Address: 1. Connect to the UniGateway EH-2101W 2. On the LAN screen, locate the DHCP Server section, and set both the Start IP Address and the Finish IP Address to the IP Address you wish to be assigned to the Dial-in user. 3. Save these settings.
Appendix B About Wireless LANs B This Appendix provides some background information about using Wireless LANs (WLANs). Modes Wireless LANs can work in either of two (2) modes: • Ad-hoc • Infrastructure Ad-hoc Mode Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Stations (e.g. notebook PCs with wireless cards) communicate directly with each other. Infrastructure Mode In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations (e.g.
Appendix B - About Wireless LANs Channels The Wireless Channel sets the radio frequency used for communication. • Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference.
C Appendix C AT Commands AT Commands This Appendix details the "AT" commands used by modems and ISDN TAs. This information is provided to assist users who are using the UniGateway EH-2101W's serial (RS232 port). It is not relevant to Cable or DSL modems connected to the WAN (Ethernet) port. Required Settings For the UniGateway EH-2101W to use the Serial Port correctly, the modem or ISDN TA must be set as follows.
