RCS Partial Service and Lost MDD timeout errors

[steverosetti]

Hi

Having issues over the last week with the Hub rebooting and loss of internet.

This is causing a lot of frustration as my wife works from home.

Can anyone take a look and let me know how to solve these problems.

Hi

All seems stable at the moment, but I feel as though we are just waiting for it to start playing up again.

Speed seems to be ok as well (approx 380mb down / 37mb up) 

Here is the latest Router Status info.
