    I am currently dual booting between Ubuntu 10.10, and Windows Vista SP2. Wireless works fine in both these OSes, but when I quit Ubuntu and load Windows, 70% of the time my wireless stops working.

    ie, it does not detect any wireless networks nearby, althought there are tons of them.

    Restarting the wireless device doesnt help, I have to restart my computer at least 4 times for wireless to start working again.

    Any suggestions?

    I've encountered nearly the same problems with a wired LAN switching between Windows 7 and Ubuntu 10.10. As best we can figure out, the LAN chipset appears to be saving some config info -- which is apparently different in Ubuntu than it is in Windows. Yeah, I know that can't be true -- but it's the only thing that explains the problem.

    In my case, I have to do the following when switching back to Win7 from Ubuntu:
    1) Disconnect the wired cable from the router, wait a few seconds, plug it back in
    2) Launch the Realtek Lan Diagnostic tool in Win7 -- the diags will fail
    3) Wait a couple of minutes, run the tool again -- the diags will pass

    If I don't do this, when I boot back into Ubuntu, networking won't work.

    But, running the diags in Win7 seems to "fix" the networking for both Win7 and Ubuntu.

    Go figure!!
