Every time I start my laptop, I can't access the internet and get a "limited access" warning on my wireless network.
The "troubleshoot problems" option fixes the problem (usually by resetting the network adapter), but it's not a permanent solution, because as soon as I restart the laptop, it's the same story all over again.
I have a desktop (Windows 7) connected through ethernet and another desktop (XP Home) also connected over wifi, both working just fine.
