I have had a wireless network set up for about 3 yrs now. I use the WRT54G (firmware v1.41.2) with no encryption. I have a wired desktop and a wireless laptop that i have been using and it has been working well. I got a new laptop yesterday, dell latitude, XP with builtin wireless card. Everytime i try to connect the dell to the wireless network, it brings the network down. I have to restart the router and can connect to the internet with the desktop and the old laptop. The new Dell continues to bring the network down. Any suggestions on how i can fix this.
