This Appendix covers the most likely problems and their solutions.

Overview

This chapter covers some common problems that may be encountered while using the Broadband Router and some possible solutions to them. If you follow the suggested steps and the Broadband Router still does not function properly, contact your dealer for further advice.

General Problems

Problem 1: Can’t connect to the Broadband Router to configure it.

Solution 1: Check the following:

•The Broadband Router is properly installed, LAN connections are OK, and it is powered ON.

•Ensure that your PC and the Broadband Router are on the same network segment. (If you don't have a router, this must be the case.)

•Ensure that your PC is using an IP Address within the range 192.168.0.2 to 192.168.0.254 and thus compatible with the Broadband Router's default IP Address of 192.168.0.1.

Also, the Network Mask should be set to 255.255.255.0 to match the Broadband Router.

In Windows, you can check these settings by using Control Panel- Network to check the Properties for the TCP/IP protocol.
