Hi, my VM connection keeps dropping out intermittently, I've run the diagnostics which shows service is fine in the area, and all it does is reboot my router.

I've rebooted my router and hard-reset it with the pin, but issue still present.

Called up customer services, who told me to reset the router, then do a hard-reset. Then said they will call me back next week to see on the issue? 

Is there any team that could actually sort this out, rather than just a services of reboots and resets, and waiting around for days on end?

Let's have a look:

Can you post your Hub status and logs?
Someone should be spot if there is a problem
Navigate to http://192.168.0.1 (or http://192.168.100.1 - if in modem mode)
Don't log in!
Click on 'router status'
Copy/paste the data from each of the tabs as text into a 'REPLY' as opposed to 'QUICK REPLY'. The forum software will remove the MAC addresses for you (you will likely need to click the 'post' button again).

Also, set up a 'Broadband Quality Monitor'. This will monitor the state of your connection and record any network dropouts etc - You can do this at ThinkBroadband (https://www.thinkbroadband.com/broadband/monitoring/quality)
Give it a while to gather data and then click 'Share Live graph' and paste the 'Direct Link' into the forum!

Your upstream power is too high!

VM would need to book a tech visit to sort this out!

[Singh619]

Hi thanks for the quick reply. how do I get them to get an engineer to sort it out? I've tried the phone number multiple times and they just keep saying theres no faults and to restart my router with a pin in the back for a hard-reset.

[jbrennand]

A VM person will respond here in a day or two. The Up powers are high and there are some PostRS errors and T3's too - so while waiting can you do this.
______________________________________________
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. Also check that the internal wiring is ok with no kinking or chaffing, check that all looks good with the outside cabling and wall box (no “staples, etc.,) piercing the cables.. 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's have all reset to 0. See if the Up power levels are still high too. Then check every hour or so to see if the errors start reappearing - they shouldn't. If they do (particularly the postRS ones) you have a problem (noise) that only a Tech visit will sort - and adjust the Up power levels

I can see that starting to build - Including the drop out at the very beginning!

And what are the Hub stats showing now after the 5' switch off yesterday?
