I got poor signal when I tried using the wireless USB adapter I got with the router so in the end I installed a LAN card and that works a treat, the LAN line is fast so I'm happy, my two laptops hardly ever loose the signal and their on wireless and in the next room, yet the adapter thats plugged into my tower did and thats like 3ft from the router it just don't ad up, I can only assume that its down to the brand of wireless adapter or the firmware needs updating but as I don't use it now I'm not going to bother.
