issue is fixed.
As reported here: http://askubuntu.com/questions/132894/h ... -not-found
, there's a bug(?) in Ubuntu 12, which Mint 13 is based off, where ndiswrapper is not registered(?) as a module (whatever that is). One suggested solution was to install ndiswrapper-dkms, which I did by manually downloading it from here: http://packages.ubuntu.com/precise/all/ ... s/download
and then double-clicking the file to install it (yay for gui installation!!)... and then typing 'sudo modprobe ndiswrapper' in the terminal.
Now: wlan0 comes up, but I can't connect to a network... that is [WPA2-PSK] security enabled. I can connect to and have internet access with a non-secured network, but when trying with my actual network, it gets stuck on the "Requesting a wireless network address for [my network's name]" - "gets stuck" meaning it tries for a few seconds then gives up then restarts the process ("Configuring [blah blah], then "Requesting a wireless network [blah blah]"). Since this is a totally separate issue, I'll either make a new thread in a day or so after I try to solve the problem on my own, or if anyone wants to go ahead and offer help in this thread that'd be perfectly fine by me.
