I am trying to connect my laptop to my brother's wireless network and am having a few difficulties. The laptop is a Sony Vaio TX2XP running Windows XP and I frequently connect to other networks without a problem. My brother's network is WEP encrypted and he is running a Playstation 3 (wired) and a desktop PC (wireless) with no problems on an AOL broadband connection.
When I first set up the connection it connected fine for one day, then changed to limited or no connectivity status and now the laptop won't connect at all. When I bring up the screen to show available wireless networks all of our neighbour's protected networks are showing up but not my brother's.
