I set up a dual boot of Ubuntu and Windows 7 on my lenovo u330 laptop a couple months ago and everything was working fine. That was till I found a problem with the wireless when switching from Ubuntu over to 7. I found that if I left the wireless off in Ubuntu and restart to 7, the wireless is completely disconnected in 7. Later I learned that if I enabled the wireless in Ubuntu and restart into 7, the wireless works fine.
Now, the major problem is that the Ubuntu 11.04 update completely screwed the Ubuntu installation. The graphics nor the internet worked after the update so basically I'm stuck with the wireless off in Windows 7. Also, I deleted the Ubuntu partition to possibly reinstall it but another problem is that I got the install from a friend (who isn't around). Someone told me that Ubuntu actually shuts down the wireless card at the hardware level.
Does anyone know a low level way of enabling the wireless adapter in Windows 7? ipconfig
gives me the "Media disconnected" message on all of the adapter connections. I have already tried reinstalling wireless drivers
as well and none of the Windows 7 troubleshooting apps help whatsoever.
