Terrible Microsoft Teams

[JamesRoseUK]

Hi,

I'm a new VM customer and my connection in Microsoft Teams is awful. every other second cuts out on the audio front. This happens on multiple devices and I've already had a good read through the various posts that have already been made around this.

I have a Hub 4 and a M350 connection.

I've started a Broadband Quality Monitor on thinkbroadband already (based on previous posts) and have also run the "network diagnostic tool" in the Hub 4's configuration pages. It comes back with errors on telephone line and wifi, however it does not go in to detail and simply displays a exclamation mark.

I also have these logs:

Cable Modem StatusItem Status CommentsChannel Overview Downstream Upstream

Cable Modem Status	Online	DOCSIS 3.1
Primary downstream channel	Locked	SC-QAM
DOCSIS 3.0 channels	31	4
DOCSIS 3.1 channels	1	0

 

Ok... so what is next? Currently the service is unusable for work meetings, which is probably going to be it's main use day to day. eeeek.

Thanks so much to whoever replies!

Hi @JamesRoseUK 

Your downstream power levels are too high.

Was this a tech install or self installation?

Do you have an attenuator connected? If so it will look something like the image below.

[JamesRoseUK]

Hi Dave,

Was a self install. I don't have one of those devices connected, however the previous owners left some cables which looks to me like the had broadband and tv as the contain a splitter and two of those devices on each cable.

Do I need to use it?

Thanks

[newapollo]

Hi again James, 

Will wait for one of the more knowledgable broadband gurus' to pick this up.

To be honest I would use ethernet where possible, especially for work.

Also suggest checking all of your cabling, internal and external is finger tight, especially the white coaxial, and make sure there are no kinks in the cables.

The splitter may be the problem.  Ooh since previous people also used VM I would check that there's no staples in the cabling as lot fasten them with staples and clip the wires.

EDIT - Don't forget to post your BQM, but make sure you erase yuor ip address if it's showing on the BQM

[JamesRoseUK]

Thanks Dave,

Should note that the splitter cabling is not being used and I'm just going from the wall box to the Hub with the provided push on cable.

James

[JamesRoseUK]

As I wait for a guru to reply, should I test by putting on one of the left behind attenuators?
