My laptop has been happily connected to the internet for the past year via a Sitecom wireless router and Railink 2250 Wireless card. The other day though it dropped the signal and I haven't been able to get it back. While this has often temporarily happened before, usually if i click on 'repair connection' it restores no problem, or if I put the laptop on standby it will reconnect when i switch it on again. However, none of these tricks have worked this time and I know the wirless signal is fine from the router because i brought along my g/f's laptop yesterday and it connected to the wirless signal without any problem. Just to note that my laptop is not picking up any signal whatsoever and no network is listed when i 'Refresh network list'. Can anyone offer any advice?
