Occasional Dropouts
I am having an issue where my internet will completely disconnect for a few minutes before coming back on. It's not a Wi-Fi issue, this happens on ethernet as well.
Here is the quality monitor for today for example: https://www.thinkbroadband.com/broad...02-06-2020.png My router diagnostics seem fine when the internet is working but I cannot connect to the hub when the internet goes down! The only time I can connect is when it starts working again at which point I don't see anything wrong? Network Log: Network Log Time Priority Description 02/06/2020 11:57:28 Warning! RCS Partial Service; 02/06/2020 11:57:28 critical SYNC Timing Synchronization failure - Loss of Sync; 02/06/2020 11:47:35 Warning! RCS Partial Service; 02/06/2020 11:47:35 critical SYNC Timing Synchronization failure - Loss of Sync; 02/06/2020 10:42:40 Warning! RCS Partial Service; 02/06/2020 10:42:40 critical SYNC Timing Synchronization failure - Loss of Sync; Downstream (as time of writing) Spoiler:
Any insights/advice before I phone VM? I want to be as prepared as possible (and I have restarted the router multiple times) |
Re: Occasional Dropouts
Something is terribly wrong and I amazed your connection is working at all. You have got hundreds of thousands of post rs errors on every channel. I don't know whether that is indicative of a fault on VM's end or yours. If it is happening on VMs end everyone is fooked. Tne SNR on the downstream channel is ok, what are your power levels like on the upstream?
Without seeing your upstream power levels I am going to take a stab in the dark and say that there is noise on the line which is causing the shub to ramp up the upstream power and when it is getting too high the shub is resetting itself to try again which is why you are losing your connection for a few mins. I think a tap point change is in order and will improve your downstream power levels as well. |

Re: Occasional Dropouts
Too low. Upstream power is the shub's responsibility but I don't know whether a new shub will fix it or whether your tap point needs moving in the cabinet (or both). You can do one of two things. Normally I would want to get a tech out to see what he thinks and you have got the peace of mind the problem will be resolved. He can give you a new shub or move the tap point. The problem is that in the current climate I don't know what tech visits are like, if they are still doing them and how long a delay there is going to be if they are operating at reduced staffing levels. If they tell you it is going to be 2-3 weeks and you feel the intermittent disruption is intolerable, I would ask for a new shub to be sent out. It will be next day delivery and you can hook it up in a few mins and you'll know instantly whether the problem is fixed or not. If it isn't then you can revert to the tech visit for further investigation.

Re: Occasional Dropouts
Phoned VM and they want me to do a router reset before anything else - said downstream was fine - so I am going to do that tonight as connected to a VPN right now. I hate having to phone VM for this stuff.

I loved Occasional Dropouts, I got their 3rd album.

Setup a Think broadband graph, let's see how bad that looks. Also log into the hub and reset those errors to 0 so we can see how quickly they climb. |

If you do not have a FPA fitted then you would need a Engineer to visit to fix this .. not sure if the upstream settings are ok though :( BTW, a FPA looks like this: https://www.cableforum.uk/images/local/2020/06/1.jpg |

So unsurprisingly the factory reset didn't work. ---------- Post added at 22:23 ---------- Previous post was at 22:22 ---------- Quote:

Re: Occasional Dropouts
still seeing red, doubt it fared well overnight

Re: Occasional Dropouts
Stick a post on the VM forums then you don't need to phone up, may take a week for a response though.

Re: Occasional Dropouts
Everytime I get though they don't seem to care about that broadband monitor showing dropped packets and say the status on the modern is fine.

Nah didn't have anything fitted.
Look at what happened after 2pm! https://www.thinkbroadband.com/broad...03-06-2020.png |
