Hi there,
I used to have a hub 3 that would regularly disconnect and was impressed that for the first week my new hub 5 would be online 24/7. It was a miracle.
Now about 2 weeks later I am plagued with packet loss and random high latency every few seconds, see image attached.
I had a technician come round who had no idea how to test my internet other than speedtest on his phone. It was honestly embarassing, he didn't know what BQM was or even what I was doing when pinging google.
Please help.
Thanks,
Jon

Could you post your HUB stats?

Thanks for the reply, unfortunately when I try and access my hub stats I get the below error:

Upstream power levels look low, unless you are in a FTTP area?

Thanks for the reply. I think I'm in an FTTP area. I'm more concerned with not being able to access my downstream logs and have seen a couple of other posts about downstream issues with the hub 5.
I did ask the engineer to check my power levels when he came but he never did.

Can someone kindly review my message and book me in a technician as if I phone again the technician is going to be the same guy who uses his mobile to speedtest and confirm that my internet is ok.
Thanks

If you are not a FTTP customer then those upstream power levels are too low. You can tell if you are FTTP customer if you have a VM power plug that takes a coax cable usually going to a white box. I do not mean a power plug for your VM hub or TV box.
