Wireless router potential problem!!?

Just follow your providers instructions or the instructions on the loading disc. Your sons computer will need its own dongle or similar ( basically the receiver). It is possible you will get problems, but mine were put right by putting the router in ociation mode whilst loading the extra computer.. This becomes clearer as you try to load it. This comes from experience as my computer is on the ground floor and my husbands is on the first. Good luck.
