@nekrosoft13 - wireless never works that way. I have excellent dual-band (simultaneous) 802.11n router at home, but still prefer cable. Cable is faster and much more reliable for transfers of 100GB+ of data.
That 7Gbps will be reachable only under special laboratory conditions (ie. never at home), and devices will have to be within something like 30 inches from each other (ie. within one room).
Nothing beats good old cable.
Forget wireless, get cable instead!
