Intermittent broadband for several months!

[kan-izh]

Since I've joined in ~June, I have unstable connection. It seems works kind of ok, but during the day I have few seconds connection drops. It sounds as not a big deal, but affects me significantly especially when I am on a video call or similar.

I've had 5 or so engineer visits already, they have replaced all possible connectors and wires in the house. but it seems does not help. For couple few months I have permanent "issues in your postcode affecting your services", I've called technical support several times, they usually promise fix by tomorrow or so but there is no any progress in the fixing the issue. I have BQM installed:

Still not fixed, just had another ~30 seconds gap. This is very disappointing experience. Could you please suspend the billing until the issue is fully resolved?

We understand your frustration kan-izh, from checking your connection and equipment there does appear to be some power level issues on your downstream channels, with some errors on your upstream channel. Disconnections wise we can see one late on Friday around 9.50pm which is what you have referred to in your post but none since.

Have you noticed any improvement since that time?

Oh, thanks. It looks very promising so far. For about a week I have not experienced any issues.
Hopefully it's finally resolved for good, I'll keep an eye on it.

I think it's intermittent again. Noticed few interrupts today and I see two T3 timeouts...

Thank you for keeping us updated kan-izh.

I have taken a look on our side and it does indicate an engineer visit may help improve the issue. 

I will private message you now to confirm your details.
