As an IT professional with what I'd consider heavy and experienced usage, over the last 6 weeks I have started receiving regular disconnects varying between every 6 hours - 24 hours. Since Plusnet support seem to be overloaded, giving here a try for advice/assistance.
I'm idly wondering if Plusnet/BT are purposefully cycling something every few hours due to Covid-19 usage patterns?
Reliable for: 4 months without incidents.
Router replaced since fault manifested: yes, occurs with old and new router (including cable/power). Now utilising Plusnet One. Previously: Draytek 2860
Any internal wiring/property changes: no
Any internal wiring downstream from master: no
Any devices connected/phones connected: none - don't use POTS
Master socket used.
DSL splitter faceplate used, replacement already tried.
POTS line still has signal during outage.

Sounds similar to what I'm seeing, and someone else I noticed on Twitter. The timings feel too inconsistent to be a deliberate cycling, but something's definitely broken.
These were my router logs (Asus):

Hi @, sorry to hear you're having broadband issues.
I've had a check of the connection and there definitely seems to be something out of place somewhere as we can see the disconnections from this end, although our tests aren't picking up exactly what's causing the issue so we will have to do some troubleshooting to start ruling things out.
I'd recommend starting with basic checks here
And if that doesn't help the next thing would be to rule your internal wiring out by plugging the connection into your test socket which is under the faceplate of your master socket and seeing if the drops stop. This rules out internal wiring, face plates and extension sockets as being the cause. How to locate the test socket and set your connection into it can be found here
If the problem still persists from here we will go down the route of raising a fault, please click here and let us know once you've done the checks and raised the fault so we can progress it for you.

Thanks. You've clearly not read any of my original post, as being an IT professional, all your "basic checks" have already been performed. As has "And if that doesn't help the next thing would be to rule your internal wiring out by plugging the connection into your test socket which is under the faceplate of your master socket and seeing if the drops stop. This rules out internal wiring, face plates and extension sockets as being the cause. How to locate the test socket and set your connection into it can be found".
I'm testing a theory of my own, if still required, I'll raise a case.

Did you find a solution? I'm currently in the same boat, and despite the PN techs confidence that he had fixed the problem, he 100% has not.
Thanks.

Nope, I wasn't convinced forcing a different DHCP lease address was going to make any difference. Whilst the speed is good, I still get disconnects which range from once every 48h to once every 5 days. This shouldn't happen on xDSL.
Plusnet are either:
1. not technically knowledgeable enough to do anything (other than follow their basic script).
2. don't give a **** enough to do anything about it. Or just plain lazy.
xDSL connections should NOT reset periodically or have any form of drop outs unless there is something wrong - I've come across xDSL connections which have been up for months without incident at customer premises. They've not even been bothered enough to send an OR engineer to check outside cabling or replace the cable pairs. Since OpenReach split from BT, one of the repeated consumer problems is getting the ISP to even ENGAGE with OpenReach since they can't comprehend anything more than "well the computer says the line tests OK".
Terrible customer service (despite Plusnet=BT). Nobody is interested.
North Tyneside area is one of the first getting 'full fibre' so hopefully I can dump Plus.net soon as FFTP will at least provide higher levels of diagnostics to customer premises rather than just being 'fobbed off' constantly. Or back to Virgin. At least that way I get a stable reliable connection (unfortunately at double the cost).

I should also add, since then I've also replaced the router with a completely different make/model, and again replaced all cabling into the master socket, and new routers still show the same disconnect issues. Wi-Fi strength has improved however :).

Please stop shouting its rude and against forum rules apparently.
As to your issue Routers can reset/reboot if there internal memory becomes full (logs etc), although not every 4 hours usually I have found 30 days or so.
Have you logged a fault ticket? asking for GEA test etc. Its really the best way to get your issue resolved. faults.plus.net
if necessary it could then be escalated after the initial investigation from the fault ticket.

@BigBadBoss I cannot identify a drop in your connection for over 3 days, I'll attach your GEA test here now.

It's been reported at least 2/3 times now, and never goes anywhere, with the same "computer says connected" and fault closed. While this is a domestic connection with no QoS, even being synced for a month would be an improvement. It's annoyingly intermittent.
I take what you're saying about buffer overload, but I fear this unlikely after 4 different routers, including different manufacturers based on different architecture, with the same result. Those of us managing IT in industry would also probably be aware of it was, supporting our hundreds of users who now WFH due to Covid-19.
Again, sync time appears to mismatch remote testing, as I can see that the last successfully sync of the latest router was:

I think one disconnection every 2 to 5 days is not enough to be considered a fault. Yes you might find some xDSL connections that stay connected for months, but an occasional disconnection is quite normal and to be expected really. So there seems to be no fault and therefore nothing to fix here.
