I'm having problems with a new (6 weeks old) Vista laptop on my wireless nertwork.
The network works OK with XP machines and with a new Linux eeepc.
The vista laptop works fine for news, email and bit torrents. I can ping the internet. Web access is intermittent and keeps dropping out. For example I can ping my adsl router but not access it in firefox or IE using its IP address.
I just tried accessing a bank using https rather than http. I got an error message that the security cert was invalid for
I've turned off the windows firewall and I am using Avast as a virus scanner.
Any thoughts appreciated.
