If it rains, and water gets into the broadband infrastructure, cabinets, cables underground or overground, disrupting your broadband signal, that’s a broadband fault.
Qualitatively different from rain affecting terrestrial TV reception.
Also, either problem would likely affect other channels, not just one.
The point being made here is that it is difficult to think of a possible single cause for the disruption of both terrestrial aerial reception and broadband reception, as they are such different things. Unless your house has a serious water leak of course, e.g. a leaky roof; and I think you would have noticed that.
This is getting worse.Yesterday i noticed a change in the EPG,the letters EE appeared in the top left hand corner & the whole thing was so slow it was painful,if i selected an program it eventually moved to it & the item was now coloured.I gave up on it & went to my TV tuner which worked fine.This morning i switched on i eventually got an incomplete EPG tried to select a channel & couldn't,couldn't get to settings,i was going to reset the box,then the EPG what there was of it disappeared completely.I tried switching the box off ,it went through thr loading process & then nothing,just a blank screen.
Yesterday i managed to get to the prime app,it started,then disappeared & reverted to the the chat at the end of the ITV football.
Sounds like you've been sent another duff box. There have also been a few reports of the software update to EE branding killing a few older boxes. I think you need to get on the phone again for another replacement.
I switcded on again,managed to somehow get to settings & reset the box,it's going through the guide set up at the moment,will get back when it's finished & i've checked if it works.
UPDATE.
Reset the box twice yesterday checked software,on latest .The epg loaded ok this morning,raining heavily here,bbc 1 & 2 unwatchable but seem ok in HD.itv seem ok.
Regarding Darrens info regarding TNT sports being from my broadband connection,i left it on ,all seemed ok but then the picture started freezing & restarting.,iplayer seems ok.
Only have a couple of recordings on this box but they play ok,no breaking up.BBC1 & 2 ,also unwatchable through my TV tuner,it has it's own aerial connection,not connected from an aerial out from the youview box.Will see how things go over the weekend.
An update.
Haven't got around to contacting BT again about the box,other issues to deal with at the moment.I've reset the box ,must be 5 to 6 times now.
I tried watching the football last night & the picture would freeze & come back on again.I tried something using the discovery plus app,It's available through my TV apps,not on the youview box apps..I don't normally watch discovery but i was playing around a few days ago & noticed a sport thing,i clicked it & the arsenal match was there,i clicked it & was offered ,start from beginning or live,i clicked live & there it was ,no freezing or sound loss.I'm assuming that it was all coming from TNT sports.(Broardband),same commentary team etc.So why would the picture through the youview box freeze but the discovery app be ok,no issues.
I'll check it out again ,other matches tonight & Thursday,if it works i suppose it's a work around for now.
Apart from the two sets of hardware being completely different, the delivery methods of the streams is also different. It would be worth trying the iPlayer app on the BT box to see if there are issues there.
Without trawling back through this & your original thread, are you using a BT Hub & connected to it directly?
