Constant T3/T4 Timeouts and Disconnects – Virgin Hub 6

Question

Hi all,I'm hoping someone can help me or point me in the right direction.For the past few weeks, I've been experiencing frequent disconnections on my Virgin Media broadband using a Hub 6.Initially it was happening twice a day (for over 8 months now), but in the last weeks it has escalated to disconnecting every few minutes.What I've Done So Far:Rebooted the hub multiple times, replaced the coaxial cable from wall to modem, confirmed all connections are tight and corrosion-free, my Hub been replaced by the ISP after talking with support.Had a technician that told me he need to open a call to the network team but the support didn't find such call, they set me a new technician to arrive but the only time for visit is two weeks and i'm working from home 100% and cant work atm :(no other ISP offer service in my area in Dublin...Is there anything i can do? as far as i can tell the issue is noise on the line, but support wont let me talk with anyone in the network team.&nbsp;Thanks!Modem Log Errors - These are recurring in the logs:T3 timeouts: "No Ranging Response received",&nbsp; T4 timeouts: "No Unicast Maintenance opportunities received", "Received Response to Broadcast Maintenance Request, but no Unicast Maintenance opportunities", "ToD request sent – No response"The logs flood with these events during and before disconnections.DOCSIS 3.0 Downstream Channels:| Ch | Freq (Hz) &nbsp;

I'd certainly agree that this is an upstream problem.&nbsp;

Difficult for anyone here to offer advice as this is the UK forum and we don't use the Hub 6.&nbsp; There isn't much noise showing on your figures, but that would be normal shortly after a reset. Too many T2s though. What does it look like after a few days?&nbsp;

Ash_101 · Answer

Since i didn't managed to get any help from the tech support here i hopes the forums (even if UK) could help me confirm that this is network issue on the ISP side...

After few days upstream T3 and T4 timeouts are in the dozens or even hundreds, dozens downstream 3.0 post RS errors and the downstream 3.1 have hundreds of millions corrected errors.

I don't blame you for reaching out, it sounds like your tech support is no better than ours.

A Hub exchange sounds like a good first step, if you can get one, but this does sound like an external network issue. Have you checked whether your neighbours have similar problems?

Ash_101 · Answer

Support already sent me a new hub, but unfortunately, it didn’t resolve the issue. I also know for certain that one of my neighbors is experiencing similar problems — I’ve seen a technician at their property several times recently.

My best guess is that this is due to upstream noise or interference at the cabinet, node, or CMTS. It’s been a while since I last worked with broadband infrastructure, so I was hoping someone here might have a tip or insight I’ve overlooked.

Looks like it’s time to call support again... :)
