I wondered if someone could help, I am tearing my hair out with this one. My Mum had wireless router with Tiscali as her ISP. The router packed up and they sent a new one. It installs and works as advertised. However: My laptop (Windows 7) can access the network & internet wirelessly, my work Laptop (Windows XP) can access both no problem, but my mum's laptop will only get a local connection and it continues no matter what I try to say unidentified network. I have tried the usual turn on / off etc... but no luck. Has anyone any ideas?
I should have said " delete the old profile from your mothers PC for the old router " In XPscan for new routers , on left hand side of page look for Manage wireless networks , find old profile and delete , same for Vista , but in Network and Sharing Centre .
If you go into the "Network and Sharing Center", where it shows Unidentified Network is there a link at the right to Customize? If so click that and see if you can set it as a Private or Public network as appropriate.
There does seem to be a nasty bug in Vista's networking where it will allow Local but not Internet access. Microsoft have acknowledged that there is an issue but appear not to have provided a solution.
However, working through the instructions in this page click here might help, but it does involve editing the registry.
