I have literally no idea what is causing the problems, but whenever I boot up, aero and my wireless connection keep crashing for the first 10-15 minutes or so.
After boot up and the desktop comes into view I can see the small white bars icon on the taskbar that indicates that I'm connected to the net, and that windows 7 aero is on (glass effect etc), but around 10 seconds afterwards the theme reverts to windows 7 basic and my wireless icon has a red cross on it.
Right clicking the wireless icon and diagnosing the problem brings up 'windows wireless service is not running on this computer' and that the diagnosis has solved the problem. After another few seconds it disconnects again, and I have to repeat the diagnosis several times to get it to 'stick'. Aero eventually returns to normal on its own after around 15 minutes.
It's very intermittent but persistent; I thought the problem had gone after 2 days of it not happening, but today it came back
