  • 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)

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
