the modem and pc are on ground/mainlevel of house - this is where the WRT54G will be located (above ground). I also have pc in the basement I want to purchase the WUSB54G for the basement. I have heard that cement and brick lower the signal strength. Does anyone have this kind of setup? I am hoping that I will be able to get the wireless signal and not have to go wire and run CAT5. If I do not get the signal - are there any products I should buy? Any suggestion before I purchase the WUSB54G?
