Operating system. From our experience Windows XP is reliable, but the latest service packs must have been installed.
Wireless hardware. If you’ve previously connected to a wireless network; it indicates that your hardware works. Our initial experience has shown that some users firmly believe that their PCs have suitable wireless hardware installed – until they find that no connection is possible. To check, go to: Control Panel -> System -> Hardware tab -> Device Manager button -> select Network Adapters from list -> select the appropriate wireless device -> Right click for sub-menu -> select Properties. The dialogue box should show "This device is working properly".
IP address. If you’ve used your PC on another wireless network, particularly a home-based one, your system may be set to a ‘fixed’ IP address. Make sure your system setting for TCP/IP is the Windows XP default ie to ‘Obtain IP address automatically’. To check, go to Control panel -> Network Connections -> select Wireless Network Connection -> right click for sub-menu -> select Properties -> Under the General tab, highlight Internet Protocol (TCP/IP) [which should be ticked] - click on Properties box -> under the General tab it should have "Obtain IP address automatically" selected. NB If an IP address is displayed it should be 192.168.11.x where x is a number between 1 and 7. If it isn't, it won't work!
Disable file sharing. Bearing in mind that the service is an ‘open’ network, you are advised to disable any file sharing options on your computer for the security of your own data.
Personal Firewall. Occasionally, making a connection may be prevented by some personal Firewall software. It may be necessary to disable it temporarily. (If you can’t make a connection, there is no risk!)
Glitch! There might be a bug/glitch/gremlin (technical terms!)
Firstly, if you sure your settings are OK, you can detect a signal and have entered the security information but it won’t connect, try re-starting your PC. It’s been known to solve the problem.
Or use the Wireless 'Repair' facility. Go to Control panel -> Network Connections -> select Wireless Network Connection -> double click or right click to get sub menu -> select Repair and let the system do what it can!
Other steps to consider are the Network Connection Wizard and/or the Network Connection trouble-shooter.
ISP status. While unlikely, at least for prolonged periods, the Broadband line and/or the Eclipse server may be down. Status can be checked by calling Eclipse on 0845 1224 111
