Hub4 latency issues.

Hey, so since updating to superhub4 I have had same latency issues over and over again.

Have been told there are issues on my line, then that they've been fixed and every time I spend an hour on hold to speak to someone they promise it's getting fixed.

Any avenues I can explore?

Re: Hub4 latency issues.

setting up a BQM would be better.

Also post the Network, Upstream and Downstream logs from the hubs admin pages back here as text

Re: Hub4 latency issues.

Your downstream power levels are just over the high threshold limit.

You'll need an engineer to put it right.

Re: Hub4 latency issues.

There is a great deal of noise on the signal and poor signal/noise ratio on all channels. Certainly needs an engineer visit to fix this and the levels up and down.

Re: Hub4 latency issues.

Hi @matt4321234,

 

Welcome to our Community Forums and thanks for posting. 

 

I am sorry to hear that you are having issues with the service. 

 

I can see currently there is an area congestion that is impacting you. The Fault Reference Number is F008848785 and the estimated time of fix 11 MAY 2021 17:00.

 

We are planning to undertake some upgrades to support the increased demand for our services in your area. When completed, any slow broadband speeds and buffering on TiVo apps you may be experiencing (particularly at peak times) will be resolved.

 

Apologies for any inconvenience caused.
