i am using the BEFW11S4 router, Firmware Version: 1.52.02 (the latest). WinXP. There are four computers connecting to the network. My problem is that MSN sign in and out constantly(sign in for a couple of mins, then sign itself out). Also, sometimes when I browse the websites, it goes smoothly for a while and maybe after a couple of mins, it gets really slow or no connectivity. Then after a min or 2, it's working fine again... and the cycle goes on. One of the solution for myself is to put my IP as the DMZ IP. However, I can only put 1 IP address for DMZ, everyone on the network uses MSN also. I tried connect my comp to the internet directly without any problems. What setting on the router/PC should I alter to stop my MSN signing in and out every couple of mins?
