Wireless .
N; Bought one rather expensive dlink adapter wireless N technology, tried every driver on dlink's site; anyway shipped it back to dlink: they are sending me a replacement(did not ask for any sales receit, just told level 3 tech that I bought it 6 wks ago made up serial #)
I will let you know how that works when I receive it back this coming week.
(of course I don't think I have wireless N networks in my vicinity)
The alfi is for 54Mbps
All of the internal wifi cards that came installed even with Sony vaios diid not even come close to the external usb w antenna jack on card(not built in antenna)
You probably should look for a wireless n adapter with an external jack for a external indoor/ or outdoor antenna on the wireless card.
If you go to Staples store, buy it there(try it out, save invoice and original packaging); if you like it, return it to the Staples store for a full refund(no questions asked)
Then you buy the same product on ebay for 40 or 60% less then the price in Staples. You follow?
Good Luck.
