Well i have had these problems for ages now, but im not too sure when they started, Im always playing with 1 bar, no more. And it has nothing to do with the servers because it is always only me who has this problem, i am always 1 second behind.. for example if i shoot a guy 5 times, on the kill cam it will only show 1 bullet, and because of the inaccuracy it will probaly never hit.
The point is i have tried other games such as Halo Reach and Modern Warfare 2 and i can connect fine, my router is fine as well, i have done everything to try and get rid of this problem, i have port forwarded, set host to local only, flushed dns, tried with an ethernet cable, reset router and stuff to defaults and still nothing has solved this problem.. also when i go onto test connection it always fails and it says "Could connect to xbox live but not to internet please connect through modem" and i dont get why because i can still play online.
The reason is why i am so eager to get it working again is because i am currently making a montage, im not some sort of cod addict.
Please someone enlighten me.. and help me fix this problem!
also don't mean to be harsh here but please don't post obvious things that i have obviously tried such as "turn router on and off" etc..
