Hi all,
I am having an issue with my broadband. Itermittently all devices will be disconnected with no internet and after a short while will reconnect. I have tried using the Hub 3 in both router and modem mode with another router both resulting in the same issue.
Downstream tab:
I restarted my hub around an hour ago to reset the error counts and seem to be getting a huge number of Pre/Post RS errors on some channels so is this potentially a signalling issue?

BQM looks good....you say a hour ago when you posted at 22:08 but your BQM does not show this only at past midnight was there a drop...
Are you using HomePlug - Network Via Mains ? is the BQM IP match your IP ?
What Is My IP Address - See Your Public Address - IPv4 & IPv6

Thanks for pointing that out. Looks like my public IP has updated at some point since I set the BQM up. Issue has been ongoing a month+ now.
I’ve updated the BQM so will let it run for a while.

Thanks for your post and reaching out to the Community Forums, Stan1231,
Sorry to hear that you have been having connections issues with your broadband. I've run some remote diagnostics and our systems show that you are currently being affected by a local area fault for SNR issues ref# F009743503 and we are working to get this sorted as quickly as possible. The current ETA fix time is 07 APR 2022 17:25. Apologies again for the inconvenience.
Cheers,
Corey C

Thanks for the response Corey.
Once the issue has been fixed I’ll keep an eye on it for a few weeks, cheers.

Hi,
We still appear to be having issues, looking at the BQM, that I provided above, you can see the huge spikes in latency/packet loss we’re still experiencing.

Hi @Carley_S
We still appear to be having issues, looking at the BQM, that I provided above, you can see the huge spikes in latency/packet loss we’re still experiencing. Getting quite fed up with it now, it’s making it extremely difficult to WFH.
