Glitches with Zoom

[gjc26]

Hi

So I've been having glitches with Zoom.

OpenReach came in and tweaked things, which brought my connection speed up from about 55mbps to just under 80mbps, but the drop outs and "your internet connection is unstable" issues persist.

I prefer to use my own router, it's a Netgear.

I wonder if there's a setup issue, here are the current settings:

Select Country: UK

Select Internet Service Provider: TalkTalk

Transfer Mode: VDSL (PTM)

DSL Mode: VDSL 2

Multiplexing Method: LLC-BASED

VPI: 8

VCI: 35

Use VLANID: 101

Priority(0~7): 0

MTU: 1500

IGMP Proxying [not disabled]

Support British Telecom (BT) IGMP Proxying [doesn't matter if enabled or disabled still glitches]

Disable SIP ALG [doesn't matter if enabled or disabled still glitches]

I think these are the key ones.

Are these correct, and any more suggestions?

Hello,

What speeds were you seeing with your other router? We can re-check the connection stats tomorrow to see if DLM has made any changes to the speed. In regards to the clock issue, are you resetting or just re-booting the router?

Thanks

[gjc26]

So after restarting these are my stats according to the router DSL information:

The Max figures are not far off what my Netgear was reporting, but my actuals seem lower as I've reported. Should these improve?

Upstream line rate (kbit/s): 20000

Downstream line rate (kbit/s): 63682

Maximum upstream rate (kbit/s): 22689

Maximum downstream rate (kbit/s): 77576

Upstream noise safety coefficient (dB): 7.2

Downstream noise safety coefficient (dB): 6.0

Line standard: Vdsl2_ANNEX_B

Upstream line attenuation (dB): 2.0

Downstream line attenuation (dB): 6.7

Upstream output power (dBm): 4.0

Downstream output power (dBm): 13.0

I've also noted in the logs that whenever I switch off, the clock reverts to 1981-01-01 00:00:00 (it eventually gets around to acquiring the correct time from the internet). Is this normal as most devices have some sort of battery backup to retain clock info?

Hi,

Thanks for the update. Sometimes it can take service centre 24hrs to update if the router has been reset. Please let us know how the connection compares.

Thanks

Hi

Thanks for this. The router was slow to the point of non-responsiveness this morning in respect of its interface (the internet still seemed to be on). Tried various things to resolve, ended up resetting and reinstating my changes (in particular password and ssid changes, turning off UPNP and WPS, turning on band steering) and it seems better now. Not sure if it was a symptom of the kernel panic thing.

I've now also turned on airtime fairness and restricted 2.4G to 20mhz.

Talktalk are still not recognising my router on the service page, so I may try turning off for a period again, but can probably only manage about 45 mins, not sure if that's enough.

If you have switched between models of router then did you leave over 30 minutes between switching the old router off, and the new router on ?. If not it would be worth switching your router off for over 30 minutes, this will ensure it creates a new session in the street cabinet when you switch it back on. Without doing this your current router will probably have connected to the session that was originally created by your old router, this can mean the new router will not give you the best performance, because it will be running with connection parameters that relate to a different type of router.

Edit : Doh !, just read your reply again and see that you have done this already, but might be worth trying again, maybe leave it off a bit longer.

[gjc26]

I should also add that the service status page is still saying it can't identify my router, but again that may resolve overnight.

Hi, thanks for looking into this.

I've not had as many calls today, but my Zoom seems better in terms of glitches.

What I have noted is that the quality of incoming images on the calls has decreased notably (didn't have the chance to ask anyone about the quality of my image). I'm guessing that this is because of the 20%+ drop in speed I've seen since changing over to the TT Router from the Netgear. I've tried switching things around (e.g. moving the router closer to the outlet, different DSL cable (yours was slower than mine), wireless and wired) but it's not helped.

I was seeing just shy of 80mbps download and 20mpbs upload on the Netgear, with speed tests of about 65-70mbps and 19-21mbps. Now it's about 62mbps download and 19.5mbps upload, with speed tests of about 56-58mbps and 16-17mbps. And it feels slower too in general use.

Is this something that's likely to improve over the next few days? I did turn off the router for about 35 mins earlier to reset it, but that didn't seem to help.

I won't be going back to the Netgear as the glitches were annoying and disruptive, but the drop in speed with the TT router is frustrating, particularly after Openreach just came in and fixed everything up infrastructure-wise.

The current firmware version for the Huawei is 1.05. We only currently upgrade to 1.06 if there's a specific issue that we know 1.06 will resolve

Chris

[gjc26]

Hi. Does the new firmware include security updates? 

[Chris-TalkTalk]

Hi gjc26,

Could you try the Zoom calls with the current firmware version and let us know how you get on

Chris

[gjc26]

Hi @Chris-TalkTalk @Michelle-TalkTalk @Debbie-TalkTalk I've done the switch out.

Is someone able to update my firmware?

2 observations; the service status page is (still) saying it can't identify my router, and my internet speed's down about 20% (both reported and tested). Are these both symptoms of the router bedding-in?

[gjc26]

Hi. I will, but it will be early next week as I won't have time today. Thanks for the help so far.

[KeithFrench]

V1.06 is the current firmware, if it isn't running that I can get TalkTalk to upgrade it for you. Please can you try this Huawei router temporarily, that way it will prove if it is your Netgear router or setup that might be the issue or if it is something else entirely?

[gjc26]

It's a Huawei Black Hub, but I'm not using it currently.

[KeithFrench]

What make/model of TalkTalk router do you have?

[gjc26]

I am not.

[Chris-TalkTalk]

OK thanks, are you using a VPN?

Chris

[gjc26]

No other issues; so we can stream Netflix / Disney UHD / HDR etc. (but I think they buffer, so tiny glitches wouldn't matter there I guess vs live-streaming).

[Chris-TalkTalk]

Hi gjc26,

Do you have any problems with music or video streaming services such as Spotify, iplayer, youtube etc?

Chris

[gjc26]

PS thank all for all the input so far.
