so I have roadrunner cable modem running through linksys wrt54gv2.2 and from that have my pc and 3 xboxes each with an xbox live account running through it. Things have been going good for almost a year now, and all of a sudded, we are all experiencing horrible lag resulting in slow, studdering games as well as booting from games occasionally. Now, it doesnt matter if I have the computer, all cable boxes, and only one xbox running, we still have the same problem, so I doubt it is a problem with bandwidth. I called xboxlive and they said it is a problem with my router they think and that I may have to download new software updates for it. I have tried this, but I have NO CLUE what to look for or HOW IN THE WORLD to install and set up these programs. Please, someone, help me. For the love of halo2, I beg you, help solve my problem. I promise I will let you win next game!
