Packet loss and upload channel 32 qam

Up to speed

Hi,

This evening I seem to be experiencing latency and packet loss. One of the hub upload channels is also on 32 qam:

My Broadband Ping - SH3_modem_mode

(Large red spike is hub restart)

 

Please can somebody take a look at this?

Thanks,

Andrew.

Hi Andrew,

My BQM is almost identical to yours around the sametime  period you began having the issues. I didn't suffer any latency, packet loss or connection issues.

I'm in the Teesside area (in case it's a localised issue that's being picked up on the BQM)

I'm not sure if the actual BQM's are showing correct readings, or if it's a glitch.

The hourly spikes in my BQM is the hub 5 exchanging data with https://samknows.com/realspeed/ 

I did reboot my hub around 10pm which was picked up on the BQM.

Hi Dave,

I must admit that it does seem remarkably similar. However, I am based in the West Midlands so unless there is a widespread issue possibly it is coincidence?

Hi again Andrew,

I've checked a few more forum posts with BQM's and they are all showing the same snapshot between around and 8 and 10pm so the BQM's were glitching and not showing our true connection details during that time period.

Go around and check all your connections and tighten them all, especailly the white coaxial cables and any isolators etc.

The from the Router Status page copy/paste 3 FULL sets of data onto here – from the Downstream, Upstream, & Network Logs pages so the tech guru's can have a closer look at your stats. You might see an error message when posting the network logs, just ignore that and press Post again and they should go through.

I had the exact same on my graph, it has started looking like that again from about 1pm today I am in Essex.

I have had a few errors pop up as well

Edit

Thats odd, when I checked 10 minutes ago 6 and 10 were on 3 errors

I've just taken a check and I appear to have an identical BQM:

My Broadband Ping - SH3_modem_mode

Are we to take it that this is a nationwide issue affecting VM (something amiss high up in there network architecture) or is it an issue with the BQM provider thinkbroadband?

I would assume it's VM related:

SNAP!

lol its so nice to see its identical through different users, when I see heavy blue when basically idling and red at top I go into full panic mode lol

 

Service checks say all is ok though

I have same, it must be BQM issue (West Midlands)
