High T3 Time outs

[preston46]

Hub 5 with 1gig.

Whilst checking why my laptop wasn't showing as connected on the Hub 5 web page, I noticed that between 24-07-2024 02:45:43 - 24-07-2024 02:45:43 on the network logs I had over 1000 T3 timeouts on channels 2-3-4.

I rebooted my hub 9 days ago because of high uncorrected errors, Is there a problem with the hub 5?

Hi @preston46 

Welcome back to the community forums 

Sorry to hear of your concerns with your T3 timeouts. 

Checking the systems at our side we cannot see any issues in the area or with your hub specifications itself. Have you since rebooted and have the T3's grown quick or had any further issues with your connection?

Hi Carley_S

I disconnected the modem 3 hours ago, checked all the cables and turned is back on, Just checked on the hub web page and so far no upstream time outs.

Downstream is already showing all channels with Pre RS Errors in the 200's, ran a speed test and i am getting 950Mbps down and  105Mbps up.

I had an engineer out to check the modem not so long ago and he said their was noise on the line from somewhere. But didn't as far as I know take it any further.
