Not good. You have hundreds of post RS errors and are missing two upstream channels. 

Check for local issues on 0800 561 0061 and failing that try a 30 second pinhole reset of the hub with no ethernet connection and ensure that all cables and connections are tight and secure and not kinked or damaged.

Sorry i seemed to miss the other two upstream channels whilst copying and pasting.

Below is them all.

Those are fine.

Those Pre RS Errors Post RS Errors, could you reboot your modem to see what those values drop down to.

[MacmillaN]

I rebooted modem and left it running for a few hours before posting these logs.

Those look okay now. 

[Martin_N]

Hi MacmillaN,

Thank you for your post. I'm very sorry for the issues you've had with your broadband. 

I have taken a look on our system and I am unable to see anything that could be causing this. 

Can you confirm if you're continuing to have issues with this?
