Get the info for your card -lspci | grep -i network- share what model card you have. Or, look up the card online to see if it's dual band capable (dual band means it also supports 5Ghz)

@GeorgeUdosen it is - but that was simply a small typo thanks to me typing fast on a phone without autocorrect :P

You can check the channels that your wireless card supports with the terminal command:
sudo iwlist chan
Please note that setting your regulatory domain may affect the usable channels. In case yours is unset, here is the procedure:
Check yours:
sudo iw reg get
If you get 00, that is a one-size-maybe-fits-all setting. Find yours here: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Then set it temporarily:
sudo iw reg set IS
Of course, substitute your country code if not Iceland. Set it permanently:
sudo nano /etc/default/crda
Change the last line to read:
REGDOMAIN=IS
Proofread carefully, save and close the text editor.
Now check again:
sudo iwlist chan
