Re: Massive latency spikes and speed drops

You have a few Post RS Errors.

Can you reboot the Hub to see if they clear.

Also two of your upstream channels are at max power of 5.1 (51 in real terms) - keep an eye on them.

The power levels on your upstream channels are quite high, mine as a comparison:

The power levels are a decimal point out due to a software/firmware bug so yours are 51/49.5 (I've manually corrected mine above).

Re: Massive latency spikes and speed drops

I noticed the BQM issue as well and enabled the setting on my router which should fix it. Do I need to make a new graph or should it update and be ok?

It looks like it's just starting to come through so leave it as is.

Re: Massive latency spikes and speed drops

The graph will update, you don't need to touch it.

I would advise leaving it running while you are with VM so that you have instant evidence of that side of your Hub.

Re: Massive latency spikes and speed drops

I can see that your BQM is starting to mature but seems to have some spikes.

https://www.thinkbroadband.com/broadband/monitoring/quality/share/5ec73a640e087dde50152883a4e828f1cf...

Have you checked the 'Check Service Status' at the top of the page ?

If nothing is showing try phoning 0800 561 0061, this will tell you of more local issues that may not be affecting the area. Be aware that it isn't a manned line.

Re: Massive latency spikes and speed drops

I just did a service check on here and called the number and everything seems to be fine, no faults. Is it possible my line may need fixing?

Re: Massive latency spikes and speed drops

Post the red block on the BQM it looks awful.

You need to contact VM to report your problem using ...

Text service on 07533051809

150 from Virgin landline.

0345 454 1111 from any other UK  phone.

Or you can wait on here for one of the VM Staff to pick up the thread but this may take a few days.
