There are many threads like this one but hell I learnt nothing from any of them. Hopefully this can be clean and straightforward and be a refference for others with the same problem.
I think my problem is common with W7.
I don't know what set's it off, but even loading up firefox will sometimes be enough, so it is not only high loads it suffers under. My internet cuts out however the diagnose and repair does fix it EVERY time by restarting the adaptor. Every time I turn on my PC I have to do this diagnose/repair before anything so my net works. It loads up already broken.
I did not have this problem with Vista beforehand. Other computers still on Vista, on the same network are not having problems. This is directly related to the instalation of W7.
I have a Belkin Wireless N USB adaptor. F5D8053 v3
I have run the msinfo32 and most of the info under network adaptor is "not available" Start>run>msinfo32

There is no yellow mark on device manager, and it is correctly identified. I did use the drivers from the website only a few hours ago after fresh instal of W7.
Much help would be appreceated, I had to 'fix' the internet 4 times just writing this short post!
Maybe I did the drivers wrong by the look of the config :S But an adaptor reset is all windows does to fix it! Even a shortcut to just doing this would give me a lot of ease, as it would save me having to sit through the whole diagnose/repair process each and every time!
