Windows 7 - Very unstable internet

I have been using Windows 7 for some time and right from the start I have been having problems with my internet connection. I am using a wireless LAN 11g PCI card from Level one. When I connect to my home network it often says "Unidentified network", then sometimes when I have connected to it, it just says "No internet access" and then when I sometimes haev internet access via the network it is very slow and othen it also f***s up again and says "No internet access" and very very few times it works fine...
What should I do?

In advance, thank you

Same problem here, just wait till someone finds a fix or MS gives a solution.

Hmm, it sucks pretty hard...

I have learned that as long as my drivers are up to date I no longer have any problems. As well may not be the same for everyone but i downloaded a TCP optimizer
SpeedGuide.net :: TCP Optimizer / Downloads. It increased my speed quite a bit. hope this helps you all out some.
