Rubbish connection stability

mcr007
On our wavelength

For the last week or so my connection is utter RUBBISH.

I get regular cut outs where audio on Zoom calls etc. goes silent.The issues affects LAN and Wifi - there have been no changes in my house.

My power levels do seem to have dropped in the router page.

This is making working from home IMPOSSIBLE and having a real impact on my ability to do my job.

As a backup I now have Vodafone broadband, which whilst only ~75mbps is much more stable. The virgin 1gbps I am paying for is becoming worthless and I am close to just cancelling.

Status page says no faults on broadband in my area.

Any last ideas before I cancel?

As well as trying the “check service,” Area status webpage" (link at top right of this forum), also try the “free & automated” Service Status number - 0800 561 0061 - which usually gives the most up to date info. and tells you of more local issues down to postcode level.

If nothing shows on there post up the hub stats as per...
______________________________________________-

In your browser’s URL box type in http://192.168.0.1  (or http://192.168.100.1 - if in modem mode) and hit return. On the first page up [there should be no need to login if you have done so before [on the New Hub4 I think you do] click on the “router status” icon/text at bottom-middle of first page up and then copy/paste as “Formatted Text” (not images) 3 FULL sets of data onto here – 2 pages from the Downstream, 2 from the Upstream, & the Network Logs page. Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you (you may need to click the "submit" button again.

Also, in the meantime... If you haven’t already, set up a free and secure “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph” (as per instructions on the TB website) when it starts to develop.

The hub stats look ok to me - Hang tight for VM Forum staff!

The log shows T3 timeouts which can cause disconnects from the CMTS - SOmething is clearly wrong!

Please do set up the BQM as @JBrennand suggests - it will really help to diagnose and prove there are isues!

Hello mcr007

Thanks for your post 

I have had a look at the signal levels from here and its showing a slight issue with your upstream power levels

Which will need an engineer to come out 

If you can check the purple envelope top right of your screen that would be great 
Regards

Can you clarify "slight issue"? Too weak? Too strong?

Hi @mcr007,

 

The power levels would be out of the specifications we'd expect therefore a technician would be required to correct these. 

 

I can see you have responded to Gareth's PM. As he is out of the office this weekend, I will PM you now so we can get the visit arranged.
