Hi there I have a problem. I use a tp-link wr340g wifi router. I can connect to it with my nokia phone, laptop and have no problem at all there (it uses window 7). But when I want to connect to the same router from my pc using a wifi usb adapter it sort of connects, but its very slow (to the point it takes it several min to open google) and it frequently disconnects (evry few minutes) and cant find the network. although its well within range.(running window 7 on the pc as well and the usb adapter works I tried it with a diferent pc) Thanks I advnce.
