First of all never had this problem before between these two computers for one year.... Ok, both computers have WinXP Pro. My cable modem is the new Linksys cable modem and my router is the Linksys BEFSR41 (latest Firmware). What happens is when both computers are logged onto Unreal Tournament Servers, or TacOps, my ping goes from 80 to like 400 on both computers. All I have to do is turn one off and the ping goes back to normal. Once again I have never had this problem before. Just all of a sudden this started happening after using the XP tweak guide(Part 2) on TWEAKTOWNS website. Please help and if you need more info just LMK..... Thanks
