*EDIT* - I will keep this thread open for anyone experiencing the same issues I had, mine are now resolved. Read threads for any solutions and see if that helps you -
The past 3 days I have experienced extreme amounts of lag, I know it's not my internet because we have 2 computers and a laptop in the house that work fine without any disconnections. Up to level 61 playing Gears Of War 3 online, I have had absolutely no issues. So I find myself rather confused when all of a sudden I can't find a single game where I am unable to move in a straight line for more than 3 seconds or shoot someone without the delay of my bullets hitting them. I am constantly rubberbanding and teleporting all over the place, it is quite literally unplayable. Sometimes I will join a game and think, 'oh that round went smoothly' then when the next round loads im back to the same problems and unable to complete a full online match. For the past 3 days I've been hoping it might sort itself out and I actually thought it may have been my xbox 360 wireless adaptor (which is now broken). But after using a spare we have which is in perfect condition, that doesn't solve the problem either. I am lost with what to do, I have tried everything! I have cleaned my disc, installed it to hard drive, re-configured my network and restarted my router countless times. I have seen similar posts on this posted a while ago, so I was hoping there is a solution by now or at least someone professional from Epic Games support can help? I live in the UK and both player-hosted/dedicated servers makes no difference to the lag I suffer. If this doesn't change then I will never be able to play Gears Of War 3 online again.. (its that bad!) PLEASE HELP ME.
