Unfortunately multiple times during the day the internet connection to my router drops (running in modem mode with a Netgear Nighthawk router). 

Here's my network log:

Power levels are not out of spec.. Upstream maybe a little high downstream maybe a little low.

I can see the odd loss of sync and T3 timeout!

VM will want to test it out - to do this, you'll need the hub in router mode.

Hello acarpe81

If you can please put the Hub into router mode and let us know 

That way we can check a few things from here 

Gareth_L

Thanks Gareth. I've just switched it back over to router mode. Kind regards

Thanks acarpe81

Will have a look right away 

Gareth_L

Hi acarpe81

I have had a look and the Downstream has flagged up an one upstream level is out of range 

It is going to need an engineer to come out

I will need to send you a private message to pass security to arrange this 
If you can check the purple envelope top right of your screen that would be great 
Regards

Are we okay calling on the number ending 0965 

Gareth_L

No, that number not used. Details sent via PM. Many thanks
