Connecting PC to the internet.
I am looking to move my pc upstairs into my office. The current issue however is that my pc is connected directly to the modem, with a ethernet cable. The way it is set up, it would be impossible for the ethernet cable to reach all the way into the my office. I was thinking connection via wifi, but really am not sure how to do that. Would I just need to install a network card into the pc? Any help would be greatly appreciated.
