Glitches with Zoom

gjc26 — Wed, 20 Apr 2022 17:18:07 GMT

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?

Hi @gjc26,

Are these glitches happening on a device that is connected to the router wired or wireless, if it is wireless have you tried running a speed test from the device to see what speed you are actually getting at the device, and are you able to try it from a device connected wired to see if it is any better.

Hi gjc26

I'm sorry to hear this.

I'm unable to connect to your router, which router are you using make and and model?

Thanks

Debbie

@Debbie-TalkTalk

It's a Netgear D7800; I wanted to check that I had the settings listed above correct in that to rule out any specific issues. The TalkTalk user guide on router setup doesn't cover all of the nuances above (e.g. for the VPI and VCI, for which I've seen other recommended settings etc.)

@Skynet_TX

I've tried both wired and wireless; the speed at the device is good (using TalkTalks speedtest through your support page), around 95-100% of the speed that both TT and my router are reporting.

It's literally just during Zoom calls, which are probably more sensitive to any drop outs etc. as it's a livestream. It's not obvious when doing anything else.

Hi gjc26

Have you tried your TalkTalk router just to see how the connection compares?

Thanks

Hi @Debbie-TalkTalk

Before I rip everything out, is it possible for you to confirm the appropriate router settings, just as if that fixes it, that would be my preferred route?

Many thanks in advance.

Hi gjc26

Have you had a look at this help page? Set up a non-TalkTalk router - TalkTalk Help & Support

Hi @Debbie-TalkTalk I have, but it doesn't cover all the facets of the settings I listed (e.g. VCI and VPI settings are only listed under non-fibre not fibre, and I'm seeing conflicting recommendations on those in this community).

Morning,

@KeithFrench - Is this something that you could provide advice on please?

Thanks

Sorry @Anonymous no I can't advise on the router settings, but if this is only affecting Zoom, is all other internet activity OK. It was asked before @gjc26, what happens when you put a TalkTalk router back on? What sort of device is Zoom running on, has there been any sort of updates on that device before these problems started?

Re: Glitches with Zoom

gjc26 — Fri, 22 Apr 2022 11:14:26 GMT

@KeithFrench it's only visibly affecting Zoom, but that's the only live-streaming I tend to use so my assumption that the kind of minor glitches I'm seeing would be less likely to have noticeable impact on other activities as they will buffer etc. My other assumption is that any settings that are off, however minor, would be more likely to affect this sort of activity.

I may try the TT router, but note e.g. that it's not had security updates in the firmware for about a year etc., so am cautious; my understanding is it also potentially gives TT employees access to my network info that I'd prefer to restrict other than for troubleshooting so I'd like to know how to switch that off (e.g. UPNP is something I'd definitely want to switch off). Happy to switch things on temporarily during troubleshooting, it's just leaving things on and potentially open.

Regarding the device, it's a new laptop; I had the same issues on my previous one (same setup, earlier model) and that was part of the reason I did a refresh, but it didn't fix the Zoom issue. All software on all my equipment is up to date (and issues have continued through successive updates).

Hi gjc26,

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

gjc26 — Fri, 22 Apr 2022 12:29:14 GMT

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).

OK thanks, are you using a VPN?

I am not.

Re: Glitches with Zoom

KeithFrench — Fri, 22 Apr 2022 13:51:30 GMT

What make/model of TalkTalk router do you have?

Re: Glitches with Zoom

gjc26 — Fri, 22 Apr 2022 14:11:08 GMT

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

Re: Glitches with Zoom

KeithFrench — Fri, 22 Apr 2022 14:14:03 GMT

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?

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