Sorry for not replying as had a few probs
Thanks to everyone who tried to help
Anyway I rang o2 up to complain and they say there is nothing they can do because when they set the snr to 15 then i get no disconnections
They told me to put the o2 box back on and leave it running at 15snr
As you can see from stats it has been running for 13 hours and shows no disconnections however routerstats shows the following spikes 4 times today but still showing 13 hours connected
