I just moved a computer for a friend from one room to another as they replaced it with a new one. That said the old one in the other room has no internet source. They want to use it in the other room. What would be the best way to get internet to that computer? It will be 20' or so from the router. It is not line of site but it is pretty close overall. I have not had to look for anything like this before so I am kind of out of the loop. Thanks.
