Initially wireless did not work - it would find wireless and would start connecting, but it would just keep prompting for the password and never connected.

I found this proposed fix on LinuxMint.com which installs an older version of the microcode (firmware) for my device.

That seems to have disabled any wireless capability. rfkill list all shows nothing and there is no wireless option in my 'taskbar'.

I'm a Linux newbie so bear with me, and let me know if I can add any command outputs that might help you help me resolve this issue! :)

I suggest you try this:

sudo su
mv /lib/firmware/iwlwifi-1000-5.ucode.backup /lib/firmware/iwlwifi-1000-5.ucode
echo "options iwlwifi 11n_disable=1 bt_coex_active=N" > /etc/modprobe.d/iwlwifi.conf
exit

Reboot and tell us if your wireless is working as expected.

Thanks for your suggestion. This restored wireless capability but the problem persists the same as before. I'm going to have a look at the link in the other comment and get some hardware details for you guys in a sec. –  Megh Jan 3 '13 at 16:20
    
I just can't sift through 14k+ lines to try to decipher what's wrong. How about a pastebin of: cat /var/log/syslog | grep etwork | tail -n30 taken just after you tried and failed to connect. dmesg doesn't show anything wrong for iwlwifi or its dependencies which is why I'd like to turn to Network Manager. Is your router set to WPA and WPA2 mixed mode? Many drivers prefer WPA2 only and not mixed mode. –  chili555 Jan 3 '13 at 16:54
    
I'm sorry! I have no idea how those logs are read anyway. pastebin.com/AtzXHWHM here you go –  Megh Jan 3 '13 at 17:00
