Alex,  A USB Wireless 5.0GHz adapter is the quickest and easiest route. You could purchase a card to install inside the unit. The adapter inside probable has 2 wires   Rick
I have 2 laptops (Inspiron 1525 and 1545) and was wondering if I can connect to my Dual Band 5GHZ router with this?  I don't see the SSID in my wireless area on my computer.  Are my laptops compatible with a 5GHZ connection?  If not, is there an adapter for it, how much is it, and it is easy to do?
