A few days back I started having trouble accessing the internet on my TV with my ROKU system. Not sure what did, but somehow creating a new network connection. Both TVs connected by ROKU work fine, as does AP computers. The 2 client computers downstairs will run the internet for a little bit, then disconnect. Then they reconnect and disconnect. We're connecting to the right network and giving the proper password when asked, but this won't go away. AP has WXP. One of the clients has Windows XP and the other client has Ubuntu.
