Latency spikes - low quality MS teams calls

Hi

I'm working from home and getting fed up with the latency when doing MS teams calls for work. I'm using a high spec laptop connected via ethernet to the network and I can't get thru calls without audio and video loss happening every 10 or so minutes. Sometimes it's fine but other times it gets tough to understand people and asking people to constantly repeat themselves. Very annoying.

I managed to capture an example using azure latency check and you can see latency is usually 40ms or so but then spikes to 600ms for 5sec or more....

IMG-20201102-WA0002.jpgdecided to run simultaneous ping to four points (from left to right): my gateway , the first VM network IP I found doing a tracert, an intermediate VM network point, lastly a server I use for work.

Usual story that packets to my router is working fast, but the ping spikes on the VM network. One example here below:

IMG-20201106-WA0003.jpg

In other examples the first VM point (2nd screen from left) can also spike. Never my internal network.

I've restarted the router, checked the coax is securely connected and nothing has changed recently with my setup.

Using M200 service.

Is this normal and expected for consumer grade internet services? Is anyone else having these issues?

Thanks

Re: Latency spikes - low quality MS teams calls

Can you set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you should post the link straight away.

Post a 'Live Link' to your BQM on here.

Instructions for posting BQM Link

Under your BQM graph are two links in red.

Click the lower link (Share Live Graph) then click generate.

Copy the text in the Direct Link box, beware, there may be more text than you can see.

On here click the Link icon (2 links chain to the left of the camera icon)

In the URL box paste the link you copied and in the ‘text to display’ box write My BQM then click OK - you can post the link straight away.

Re: Latency spikes - low quality MS teams calls

Can you please

Type 192.168.0.1 (192.168.100.1 in Modem mode) into your browser URL bar and press enter. 

Hub 2 & 3 When the page appears DO NOT LOG IN but click ‘Check Router Status’.

Hub 4 When the page appears LOG IN then click ‘Check Router Status’.

Copy and paste the contents of the Downstream, Upstream, Configuration and Network Log tabs onto here, if you get a yellow / straw box warning click the Post button again. Use one post for each tab if you wish.

Please do not use screen grabs.

A Guru will be along soon to decipher the info.

Re: Latency spikes - low quality MS teams calls

What speeds do you get at >> speedtest.net << with a direct connection using a Cat 5E or better cable between the Hub in Router Mode and a 1Gbs capable Pc/Mac/Chromebook and no other devices connected ?

Speedtest.com

Ping 12ms

Down 206.22 Mbps

Up 21.04 Mbps

Although these speedtest results are generally ok when I have attempted these before.
