Plusnet Modem loses network sync / Disconnects when on MS Teams Calls

random8237493 — Tue, 01 Mar 2022 16:20:32 GMT

Hi,

I've a recurring problem whereby my Plusnet VDSL2 router will drop the broadband connection when using MS Teams in conference calls. Flashing lights and the broadband symbol on. It might recover on its own but it seems faster to power cycle as that gets it going again after the usual wait for it to resync. We can watch Netflix all night without issues or download operating system updates etc.

It can lose sync at other times but it's pretty rare. In a teams call it happens every few hours. Hard to pin down as I don't do these calls every day etc. My BT router from a previous contract also had the same issue so it's not a Plusnet only issue. Every piece of hardware after the openreach socket has been replaced at some point and it still does it.

Any ideas what this could be and how to stop it?

Hiya @random8237493,

I'm really sorry for the drops in connection you are experiencing and for the frustrations this must be causing.

I have checked your connection and there are far more drops than what I would expect for your line. I'd like to establish which drops are from the zoom calls to help me determine the best step forward.

Can you have a look on the image below and get back to me advising which ones relate to the calls.

Thanks for coming back to me with this.

1/3 between 9-10, 15-16 - that's probably Teams
24/2 & 25/2 between 9-10 that would be Teams

23/2 - 4-9 that happened on its own while sleeping and didn't resume until I restarted the router.

The many disconnects between 23 and now could in part be a consequence of me trying to eliminate different configurations that could be causing the issue. I would not expect anything in the LAN side to be capable of causing the DSL session to disconnect but it just feels as if the connection is being used heavily when it goes down - but that could also be that's when I am most likely to notice a small outage.

In your stats are you able to pull back to a longer time period and see period of sustained connectivity? I wondering if it might relate to the amount of rainfall?

Hi @random8237493

Are you using a Plus Net Hub One?

If so, try looking through the log file looking at the time of a know failure during a Teams call, there may be an indication on why the Hub One is dropping it's connection.

http://192.168.1.254 - navigate from the landing page (Home) Troubleshooting > Event Log (you will need to admin password which found on the Hub One)

The default view for the Event Log is 'All'.

Looking at the time of a failure, look under All, might be a few pages to go through. You can ignore IN and OUT BLOCK messages as these are normal firewall events. A quick view of the category System, Boot and WAN might have a hint on what is happening, might be quicker.

WAN will detail times the DSL connection goes DOWN and UP

Be interesting if you find the text Boot reason: watchdog reset (cause: 0xn) where n is 0 1 2 or 3

HTH

A view of the Help desk TAB would also be helpful.

EDIT are you using wireless or a wired connection. Wired would be more reliable.

Team calls use Upstream bandwidth as well unlike Netflix and Updates which are downstream only (mainly)

Have you tried reducing the teams resolution

Dan.

Hi Dan,

I redacted, out of paranoia, some of the MAC addresses but hopefully I didn't damage the information contained.

The DSL connection seems to go down on its own at 04:13 ( I wasn't around to cause that in person). There's a Mac mini disconnecting at 02:16 - about 2 hrs before the PPP LCP termination

That Mac mini got an IP from the plus net router. it shouldn't be configured to connect to that (or any WIFI) SSID so I will correct that. This same Mac features in the next disconnect, also about 2 hours before, see the 2nd log pasted further below

04:13:37, 01 Mar.	(411237.890000) PTM over DSL is down after 1897 minutes uptime

02:15:44, 01 Mar.	ath00: STA 4c:20:b8:XX:XX:XX IEEE 802.11: Client disassociated

Here in the following log, in a teams call - the 15:27 restart is after a power button press to bring back the service as fast as possible while in call perhaps the power was cut before the router started to log a reconnect attempt? In this event The Miniserver has had a registration fail at 2hours (?) before I rebooted.

04:16:00, 01 Mar. - the mini server is not so obviously indicated but it's about the same minute of the hour.

plus net DHCP lease duration is set to 1 day.

Re: Plusnet Modem loses network sync / Disconnects when on MS Teams Calls

Should I be concerned about this?

12:26:19, 02 Mar.	BLOCKED 3 more packets (because of Remote administration)

In this log the 15:27 1 Mar reconnect is after a reboot where I toggled power when the blue light went out in my teams call.

09:05 - I don't know about that termination request.

I can see some of the reconnected are about 2 hours after a Mac MINISERVER tries to get an IP address - potentially that machine is bridging because it has a wired connection to the real internal LAN 192.168.0.X (double nat via UBNT USG device). I'll disable WIFi on that device.

random8237493 — Wed, 02 Mar 2022 14:58:04 GMT

Smaller log also deleted. There's no boot reason given. Not least because the most certain disconnect yesterday was rebooted because I powered the plusnet router off and on.

It looks as though the disconnect is about 2 hours after a WIFI device connects and that device also has an interface on a network that is nat'd off the plus net LAN network (192.168.0.X off 192.168.1.X) but that could be coincidence.

my topology is Plusnet router in default config, connected to a single device - Unify UBNT USG in gateway config without PPPOA. All other devices should be after that.

Re: Plusnet Modem loses network sync / Disconnects when on MS Teams Calls

Dan_the_Van — Wed, 02 Mar 2022 15:35:19 GMT

I will admit being confused by your setup.

Is it

LAN port from the Hub One (192.168.1.254) connected to a WAN port of Unify UBNT USG (192.168.1.?) with all devices connected to this with IP address on range 192.168.1.0 network?

This is double NAT and can cause issues see https://kb.netgear.com/30186/What-is-double-NAT-and-why-is-it-bad

or something else?

Have you connected the teams device to the Hub One only wired or wifi to see if the error occurs.

The event logs file have been released 🙂

PPPoE is up - Down Rate=48985Kbps, Up Rate=15933Kbps; SNR Margin Down=3.1dB, Up=5.9dB

Looking at the log file, I see an number of device connecting on 5 GHz wireless and ubnt IP: 192.168.1.156 connecting

Have you turned 2.4 GHz wireless off as I don't see it starting?

You have a number of

09:05:07, 01 Mar. (428728.160000) PPP LCP Send Termination Request [User request]

User request is usually the Hub One as it lost it connections upstream or something upstream has told the Hub One to terminate the connection. LCP is Link Control Protocol

Disconnects overnight can be as a result of maintenance as in most cases can be disconnected.

Have you checked the phone for noise dial 17070 take option 2 with a corded phone, there should not be any noise. When I have random disconnects I have listened to the phone line during the disconnect event and have heard noise. Intermittent faults are not quick to resolve.

I would suggest connecting the Hub One to the test phone socket found behind the master socket faceplate.

Gandalf — Wed, 02 Mar 2022 17:03:29 GMT

Hi there,

I'm really sorry to see your connection's dropping, and thanks for the detail.

I wouldn't be concerned about the blocked packets as that's likely just your router's firewall doing its job.

I've attached below a graph from around the last 30 days showing your connection:

I've also tested your line today and the diagnostics are showing "line issue detected" so in addition to trying the above steps Dan's suggested, I think it's worth arranging an Openreach engineer visit to take a closer look.

Would you be able to reply to the ticket I've created on your account Here with when you'll be available for a visit? If you can post back once you've responded, I'll make sure we book the engineer as soon as we can.

2.4Ghz is off - too crowded

5Hz has been on but it's off again now. I don't think it's material to the issue.

the LCP is interesting - the USG is just a client device - it has no special privs and should no more be able to request a disconnect than any other lan/wifi client - e.g. they'd need the credentials for the router config? The USG has a PPPOA option but it's not enabled.

I haven't had any teams calls today and haven't lost connection.

Re: Plusnet Modem loses network sync / Disconnects when on MS Teams Calls

Dan_the_Van — Wed, 02 Mar 2022 17:12:13 GMT

2.4 GHz being off was an observation, anyway @Gandalf has detected an issue so I'd progress with the ticket that he has raised.

Hope Openreach find the issue quickly.

Dan.
