Intermittent Connection Loss Since Hub4 Firmware Update

[MCLS_2022]

Since the firmware update (solid green light for bridge mode)

I am getting constant modem resets, due to the new light system I can’t self de bug what is happening.

internet goes down, light flashes white, then goes to solid green then connection comes back

this is happened around 10-15 times today (previously this had happened but maybe 1-2 a week)

what the hell is going on since the firmware update?

Reset it one would hope VM test the firmware then taking the word of the one doing the firmware saying it will work.

Check with Area faults on 0800 561 0061 If you have a VM landline 150 this goes down to post code level.

[MCLS_2022]

No area faults when calling that number, but just received a text message saying there are planned works in the area for tomorrow so maybe it’s that

[MCLS_2022]

This has happened through the day maybe 30 times (sometimes it’s a yellow flashing light other times it’s a white flashing light) internet only drops for maybe a couple of mins then reconnects

Modem seems to be resetting itself constantly sometimes every couple of mins other times it may stay connected for 10mins before it resets again.

I wonder if it’s the heat as this started getting really bad from yesterday (modem is in a shaded part of the house and no where near sun light) was told on engineer can only come by the end of the week, but work from home so I’m pretty….. (insert expletive)

It's unlikely a firmware update has caused your Docsis levels to be poor, your line needs fixing.
