Hello All Don't want to bore you much with this issue but tried solving it with Linksys support but they take ages to answer and have to go through everything from zero everytime i lose contact with them. - I have WRT54G V5 with firmware 1.00.6 connects to ADSL Sagem modem - 1 PC with Sitecom network adapter running on WIN XP Pro connect to Router through Wifi - 1 vaio laptop with builtin Intel wifi network running on WIN Home connect to Router though wifi The problem occures when I have my pc connected to the router. When I try to connect my laptop to the router the whole network disconnects and it connects back automatically. So I am confused why my router disconnects the whole network when i try to connect my laptop to it. The connection goes back to normal when both PC and Laptop reconnect to the network. I'll be glad to provide more info about the situation, but maybe someone could fill me up on why this is happening. I have tried manual DHCP and automatic and still the same problem.
