sooo, i seem to get massive lag whenever my roommate jumps on the internet. when he gets on the computer i go down to about 2 bars, when hes on his ps3 i go down to one bar. it pisses me off that it cuts me out and not him. my xbox is located in my room and the router is located in the kitchen literally 15 feet from me with a wall between us. ive tried connecting directly to the router and it still stays the same. any solutions? also i do the test on the network settings and i have full strength. it only appears to lag in game. it never did this at my previous house and the router was located further away and condtantly had 4 people on the internet all day.
