Every time I play online on my Xbox I get a lag spike that lasts about 10-15 seconds which I timed the occurrence off and it seems to happen every 25-40 minutes so it's happening quite often it's becoming a problem as I like to play competitive as well.
After the engineer came last week, roughly about five minutes in to a game on my Xbox it lagged it didn't quite the same, but now it seems much worse, more sporadic, it lasts for longer and is happening a lot more often. The engineer explained how the original fitter of our virgin router and and TiVo box didn't do a very good job with the installation either. In reply to the question of which router we have it is the hub 3 I believe.
