Hello All,
A few days ago, I've noticed that my wireless has suddenly stopped working properly on my computer. It lasts a few hours, survives a few on/offs with the wireless switch (Fn + F2), but then it simply does not work when I turn on my wireless again. The wireless icon in the top right indicates that the wireless is disabled, and when I attempt to toggle Airplane Mode in the network manager in Settings, that message changes to "device not ready". In order to get it working again, I have to dual-boot back into Windows (where it isn't working there either when I boot it up), and disable/reenable the device driver in there using Device Manager. Not even a cold shutdown does it any good.
I am in the bad state right now, connected to my Ethernet for Internet. This is infeasible for me because my school does not have wired Internet virtually anywhere.
I should also note that I also installed Dansguardian and Squid 3 on my computer a few days ago and did not experience the problem before this. But I can't help but feel uneasy about the state of my laptop since I have to fiddle around with it in Windows as well to get it to work. And disconnecting Dansguardian and Squid did not restore my wireless Internet, as far as I can tell. I'll have to see what happens if I uninstall them.
Does anyone have any ideas? Thank you very much for your help.

EDIT: Bypassing the proxies and disabling DansGuardian and Squid allowed the wireless to work again (without booting into Windows) but as soon as I turn it off using the hardware switch, it won't turn back on again.
