Sisters wireless card on the laptop only gave about 16Mbs when the minute before I could do the full wack.
Try what I say here and replace the wireless card in the wifes computer. Wireless G was ok for sister when quality 4.5mbs broadband from orange, rubbish and sure the line lengt should have done more. Not that far from downtown exchange.

Phone connected at 72Mbs so that is normal so I think the HH3 will do both ok at the same time but wife machine will never do the good infinity speed.
Wirless card are cheap enough on ebay if you have that.
What I did in readyness for sister at her house. Same size and make of card, like on the other posting just the better n one.
What I think but no expert, bound to be proven wrong!.
Still phone downloads normal speed when computer is forced to g standard so thing router will do both at same time but rubbish G card, a no i think by my experiments with what I have.
