I've been having dropouts similar to what I've seen in other posts but wanted to make my own for visibility, they occur a good 10 or so times a day at fairly random intervals for a couple of minutes in each instance, been going on for weeks now. We had a hub replacement, followed by an engineer visit (changed the attenuator) then another engineer (same again, removed the previous attenuator) and now whenever I call they tell me they can't see any problem. I had one operator try to convince me it was because I was using a long ethernet cable (20m... it's hardly a seafloor cable), despite the fact that all my wired and WiFi devices disconnect at the same time, then I had another operator tell me they were going to send something to my hub within the next 24 hours that should stabilise the connection, whether he was just lying to get me off the phone or whether he really did that and it just hasn't worked I don't know but that was over 24 hours ago now so I gave it the time I was told to and it's had no effect whatsoever.
I'll post my logs below in case they're helpful at all. I really don't want to leave VM as we get a much faster connection than we would on a copper line, I'm on 350 where we'd get max 80 on the any of the other providers that're on the openreach network, but at least then I'd potentially have a stable line (I work for Openreach so I'd even be able to fix my own faults that way)...
An engineer came yesterday and showed us that one of our downstream frequencies looked bad and replacing our isolator seemed to bring it into line, however overnight it's had more of the same, I don't have any TV box so I'm afraid it's nothing to do with that BATCH007.
