I am running Linux Mint 12 (32-Bit). If my wireless is on by default, it works fine though it says in the sysmonitor applet that it's only at 51% when it used to be around 97%. If wireless is off and I turn it on using network manager, Linux instantly does a hard freeze - no ctrl+alt+del, Alt+F2.....nothing- I have googled it for about 3 days now and found nothing. Ran fsck and says all is fine...did full fsck..same thing. Did badsector scan....didn't solve anything. Wirless works 100% in my Windows 7 partition. Here are the results of my lspci and lsmod
