Unworkably slow upload speed (Hub3 in modem mode)

[therealpitchy]

We have M200 broadband to our house with a new line installed back in late 2021. We had no end of issues with the Hub3 struggling with the number of wifi devices so switched the Hub into modem mode and installed an ASUS router to better handle the LAN.

We've been having increasing levels of poor performance on upload speed. Speed tests frequently come back with c130-150mbps download but 0.01-0.1mbps upload which means that video conferences can only be done if outbound video is off.

Having looked at other threads (apologies if the etiquette is to add to an existing thread), here's the Download and Upload specs from the router (192.168.100.1)

I set up a BQM...

How can we fix this? Rebooting the modem doesn't seem to do anything.

You almost certainly need a technician’s visit.

Check with Area faults on 0800 561 0061 If you have a VM landline 150 this goes down to post code level. You could also try the web page http://www.virginmedia.com/servicechecker although this only covers large outages.

VM will not dispatch any technicians while an area fault exists.

If no faults found:

Call Customer Services on 0345 454 1111/150 if you have a VM landline or wait two or three days for a VM staff member to get to your post.

Whilst waiting can you clear the error counts by doing this and see how quickly they return
_________________________________

Switch the Hub off and unplug it from the mains supply for five minutes. Whilst it's off, do a quick check that all of your coax cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Then switch the Hub back on and leave ~5 minutes

When all done, check back in the settings and ensure that the RS error counts and T3 errors have all reset to 0. Then check every hour or so to see if they start reappearing - they shouldn't. If they do (particularly the postRS and T3 ones) then as Tudor has set you do have a problem (noise) that only a Tech visit will sort.
