Hi

I was with UNO for years using various modems and the ZyXEL VMG1312-B10A, as a router and in modem only mode, and never had random PPP drops, but no longer with them so can't say if I would be seeing the same as you now.  However this was a thing at PlusNet many years ago when they put some of us on LLU, and turns out it was a configuration issue with their gateways and eventually it was fixed at their end.

Have you got a Thinkbroadband BQM set up, is there lots of packet loss or slow responses that could point to an issue with the line?  If that chart is all okay then interference on the line at the xDSL level isn't your issue, and most lines in the UK will likely test positive for some interference, its the nature of the beast.

So if sync remains stable, error rates are in normal range, BQM shows no packet loss or other issues, then the problem is most likely at UNOs side (or kit en-route) under the assumption you've swapped your kit and ruled it out. If it started recently then does that coincide with any configuration changes or firmware updates UNO made to their kit, of course you may not have that level of information or it could be changes made elsewhere on Openreach's kit.

If UNO have no other customers they can see with the same issue in their logs then I would think it must be some kit sat in between somewhere and likely other people are affected with other ISPs, unless you can all get together, as a lone person trying to get it resolved, it could be a long battle.  Swapping ISPs may resolve the issue, or it may continue, if it continues you will be starting again with a new ISP to get it resolved.  Good luck, let us know how it goes.

Regards

Phil

See my post on TBB for graphs and BQM. https://forums.thinkbroadband.com/general/t/4657726-re-line-drops-under-load-random.html

Phil I cant see any problems on the graphs around the drop times. It is random, I setup hourly testing of 1gb file and it would drop every 4 hours but OR said hammering the line would affect their monitoring so have changed it to d/l a file every 4 hours and random tests when I am on the PC. The is some PL around the drop times but that could be the actual disconnect itself on BQM.

Can you confirm if it's a port swap on the same card or different card?

AFAIK its a different card.

The is some PL around the drop times but that could be the actual disconnect itself on BQM.

Can see the packet loss but hard to know from that chart if the packet loss comes first which then causes PPP to drop, or PPP drops then you get the packet loss.  It's unusual that noise on the line would cause enough errors to cause PPP to drop but doesn't cause the modem to resync, plus your errors logged are negligible.

Seems like this is an issue higher up the stack and not related to the physical connection.

One test you could try is putting the router in modem only mode then creating a PPPoE connection via a PC directly connected and try the downloads and see if that drops the connection still.  This basically rules out anything your end including anything else on the network/Wi-Fi given you've already tried different modems/routers.

Good luck.

Regards

Phil

Got my ZyXel VMG-1312-B10D today and it works well with a 3 dongle. It was Zen branded so after I cleared the ROM I was able to upgrade the firmware to the latest. I'm not 'allowed' to put it on my line because OR and Uno are monitoring DSL and also I want my 3db SNR back.

Still getting disconnections under load. One thing I have noticed in my router log is below

2020-09-10 03:40:59 [6] PPP: ppp1 rcvd [LCP TermReq id=0xe5]
2020-09-10 03:40:59 [3] PPP: ppp1 LCP down
2020-09-10 03:40:59 [4] PPP: ppp1 LCP down
2020-09-10 03:40:59 [6] PPP: ppp1 sent [LCP TermAck id=0xe5]
2020-09-10 03:40:59 [6] PPP: ppp1 rcvd [LCP TermReq id=0x1]
2020-09-10 03:40:59 [6] PPP: ppp1 sent [LCP TermAck id=0x1]

Which looks like the server requested a termination of the session because of 0xe5 if only I know what that reason code was.

Just had a DLM re-sync. Interleave from 4 DS to 8.

The answer isn't always switch to AAISP.

This.

I maybe jumping the gun, but as of 23:14 11.09.20 it appears fixed. Dont ask me what has changed other than sessions stay up and PPP echo packets appear to be getting through.

Still waiting for 3db using a TP-Link router which seems stable. But I plan to re-instate the ZyXel VMG-1312-B10A when I have 3db back.

A question in the BB properties of the Zyxel, which is best for stability Auto Connect, Connect on Demand or Manual connect? What is yours set at?

Changed router back to the ZyXel VMG-1312-B10A as it has higher sync and lower errors than the TP-Link WD9970.

Just discovered that the 1312-B10A has DOS protection. Wondered why my speedtester was dropping pings as it works outbound as well as inbound. Now disabled.

Uno Session History has no data now, backend problems apparently or to stop me looking at it.  :lol:

2020-09-10 03:40:59 [6] PPP: ppp1 rcvd [LCP TermReq id=0xe5]
2020-09-10 03:40:59 [3] PPP: ppp1 LCP down
2020-09-10 03:40:59 [4] PPP: ppp1 LCP down
2020-09-10 03:40:59 [6] PPP: ppp1 sent [LCP TermAck id=0xe5]
2020-09-10 03:40:59 [6] PPP: ppp1 rcvd [LCP TermReq id=0x1]
2020-09-10 03:40:59 [6] PPP: ppp1 sent [LCP TermAck id=0x1]

Which looks like the server requested a termination of the session because of 0xe5 if only I know what that reason code was.

http://pptpclient.sourceforge.net/howto-diagnosis.phtml#lcp_term_authentication

For the 0xe5 bit, I had to wander over to CCP

https://sourceforge.net/p/pptpclient/mailman/message/19160901/

rcvd [CCP TermReq id=0xe5]
CCP terminated by peer
sent [CCP TermAck id=0xe5]
Compression disabled by peer

Someone else is welcome to correct me, but this reads like a compression issue between the ISP and yourself.
