Melton Mowbray Area.
For the past few days at around 1am-2am my TV/Internet die completely, could be for minutes, hours, random times but around this time everything goes to heck.
Basically it starts with my TVs picture breaking up and freezing, as im browsing online at the time I'm not paying much attention to my modems stats, then as my internet dies, my tv dies too.
I noticed that during that time I have ZERO download or Upload channels, seen it change to 1 download channel briefly before losing connection.
Well anyway the stats. I know my downstream is high, but I still get the full 6 or so mb/s download speed(Full 50mb) when dowloading..

Oddly enough, connection works PERFECTLY during the day, just at night for 2 days now it goes dead between 1-2am..
Sorry I dont have much in the way of stats, reseting the modem and stuff when this problem occurs can do that, but the event log I posted for the past 2 days should prove something anyway..
I'm on XXL broadband.
From staring at the stats during this time, I noticed my modem kept trying to reconnect to the network going through different frequencys but couldnt lock, kinda like it was knocked off the network somehow and was trying to get back on.
