I have a WRT54GS router and a PC connected via a cable. My other PC is connected with a Wireless-G PCI card. I don't have a problem with the cable-connected PC but the other with the wireless card kicks out constantly. The PC with the card is less than 25 feet away, just a couple of walls and no windows or doors. I've updated the drivers, the firmware but the signal strength never goes above low. I've tried searching the forums but when I get 1400 results, I thought it would just be better to post and see if someone can point me in the right direction.
