@Anonymous at around 9pm last night something else happened and the dropped packets disappeared!   I tested and the SSL problem could no longer be recreated, and neither so far this morning..   Speed upload test also radically improved. It's the firs time I've seen burst to 0.7mbs in weeks!   I just wonder what's caused it and expect it's going to come back...     ... View more

@Anonymous thanks for the analysis.    About the level of errors - I'm wondering two things: What's the 'normal' error rate for my line? It's 1400m of copper to the exchange What might have changed since end of November when this started happening.. you said Xmas lights well it's not us that has them on 24/7 but some people nearby do.. I would doubt an underground cable would be susceptible... ... View more

@Anonymous I managed to rig my old windows phone on the dnz so that I could do a think broadband ping test. At around 10pm last night I removed the tp link router so the only access to internet is via the hub one 5g WiFi channel so the resulting overnight profile is a quiet line test.    During the time the tp link was disconnected I did a couple of tests one at about 2230 and another about 0730 Sunday morning. Immediately with only one device (plus the win phone on dnz) I see high latency. In both tests I created the SSL errors in chrome, although it was much worse on Sunday at 730.   I'm a bit baffled as what the sudden step improvement is at 4am on Sunday.   Looks to me like congestion in the exchange or Plusnet @willcutforth if it can't even handle a single device during quiet hours! ...

  @Anonymous - also I wanted to say that I don't believe the data sent and received stats. The line test took place just over an hour ago and I'm supposed to have downloaded 9.4 GB of data and sent 1.2 GB - considering the line speeds I have its very unlikely. I don't think I'd be able to upload much more then a few 100 MB in an hour.. ... View more

My neighbour briefly used 4g modem before giving up and switching to Starlink 2. 4g is unreliable here. I wanted to add about the strange nature of outages we had last week. Whereas normally the hub one would sense disconnection and automatically reconnect in this case we would lose access but the hub stay connected. When I tried the draytek router same problem, but it was solved by switching from ARP detect to Ping for WAN connection detection. I set Draytek to ping Google server 8.8.8.8. This worked and when the connection went down it reconnected automatically. It suggested to me that problems were occurring the other side of the Plusnet gateway? I assume ARP detect is pinging the gateway automatically? ... View more

It's baffling yes. But the actual upload speed has rarely if ever been near 1mb. Since around 25th November it's radically deteriorated and for a time it averaged 0.1 mbs. The only time I've observed respectable upload speeds is for a short time on Friday morning 1st December. This was about an hour before the second Openreach visit. Briefly got about 0.8 mbs. I use the broadband for work up until this started I was able to share my screen on Teams without problems now it's virtually impossible... ... View more

Hi PlanetX   I tried the following: disconnected the hub one from the tp-link. hub one wifi is already disabled connected our home HP laptop to the router via ethernet (needed dell USB C dock) did some tests - as expected the internet is more responsive being the only device - however it didn't take long browsing in Chrome to hit the ERR_SSL_BAD_RECORD_MAC_ALERT error (John Lewis website is a good candidate - especially if you login to your account). I did several think broadband speed tests - I've attached a sample - they are all similar - down 10-14 mbs and up around 0.2-0.4. I attempted to run the bufferbloat test - I tried about 6 or 7 times and it either won't run at all or never gets past the initial Unloaded latency test (I waited around 5 minutes in one test at the Download stage but it just stops. I also have a screenshot attached with F12 console as I see some errors. I attempted running this test using Firefox and Chrome. I disabled ad blockers etc in FF. Sometimes the think broadband speed test also hangs at the upload stage. I'm assuming its a problem with my upload latency possibly. ... View more

Only hesitation is that testing using the Draytek coincided with my line profile down speed dropping from 16mbs to 11mbs. I decided that the Plusnet one hub did as good a job if not better ... View more

Thanks - what you say makes sense.    It doesn't fully explain why I got the SSL errors when I connected to Plusnet hub  direct to the router in my tests last week (since I disconnected everything to do that). But that was using my work laptop - so the work laptop might possibly congest the network due to any number of maintenance agents that our IT dep't impose on us.   I'm going to do a test with everything disconnected and using the home HP laptop via ethernet - I just realized I can do this even though I don't have a ethernet to usb c adapter because I can use my work dell dock.   You mentioned the using TP  Link + bridge mode + QoS - well the Draytec 2760n is capable but I thought bridge mode PPPoE only suitable for VDSL and not ADSL2+?    https://www.draytek.co.uk/support/guides/kb-router-as-dsl-modem ...

That BQM and the high upload/download data ratio looks like it supports my hypothesis, that excessive upload latency is causing packet loss, causing packet re-transmission, causing connection to collapse, and potentially the frequent packet loss is breaking the SSL handshake protocol, that manifests in the errors you see.   If your bufferbloat test "Upload Active Latency" is greater than +30ms, then somehow you are going to need to implement QoS,  to prioritise and regulate the rate of traffic being sent from your network before it hits your modem.   What would make it deteriorate to this extent in the last 2 weeks? Line fault or something else? The TP-Link router is a recent thing - I only added this because the second Openreach engineer recommended getting rid of Powerline converters. Hub one had been working reasonably well for the last 20 months and before that John Lewis broadband was OK. ... View more

You seem to have a data hungry network.

Thanks Dan, yes I had assumed that, BUT I've checked and the TP-Link does have QoS when used in 'router' mode rather than 'Wireless Access Point" mode. If the resulting bufferbloat is a disastrous "F",  my suggestion would be use the TP-Link as a router (with QoS enabled), and come up with a better solution for a modem,  either by bridging the DrayTek, or suggesting getting an eBay  Vigor 130, or a Billion 7800 or 8800 of some description that can be bridged. I'm using TP-Link in Access Point Mode. ... View more

On a WIRED connection, AND for a couple of minutes when NOBODY is actively using your broadband, can you post a screenshot of the "BUFFERBLOAT GRADE", "LATENCY" and "SPEED" results you get from this test - https://www.waveform.com/tools/bufferbloat  On ADSL2+, you should be able to achieve a "B" or better   Thanks - I will try that later - what I want is a time when no-one is using the broadband and also when I observe the errors or slowness. Generally I'd just like to comment - I'm not getting hung up on analyzing why/if there might be a problem with my Plusnet hub to TP Link access point setup - when I test I will eliminate the TP Link and go straight into the router via ethernet - if the fault disappears then happy to look into suggestions. ...

What firmware does the DrayTek Vigor 2760 have installed ? Its got the latest firmware available but not its end of life so no firmware past late 2022. 3.8.9.6 BT The reason I'm not using it now it as suspected it was causing instability (or not improving things)   I'm thinking that this modem/router does support 'bridge' mode (i.e. the routing features are bypassed), and from the kit you have to hand is probably the best candidate to be configured as a simple modem, with a view to using that in place of your Hub 1, and use the TP-Link as your router+WiFi TP-Link is configured as Access Point - according to all documentation this setup should work with any modem/router.   I suspect the likely reason for your various SSL errors will be "Double NAT" caused by having two routers wired in series. I disagree: same issues plugging straight into the Plusnet hub (or whatever modem / router I use) if I disconnect the TP lInk. same errors if I switch back to Plusnet wifi and use it as supplied (or if I connect direct to ethernet - given I can only do this with Dell Laptop). same errors connected directly to draytek, bt or sagecom 2704 router.    ...
