No Ranging Response received - T3 time-out

Hi there,

We are having persistent issues with high latency and high jitter which are affecting our home network

The network logs show T3 time-out. I restarted the Hub 3.0 since the last once at 9am.

We've had this issue previously and it was fixed when an engineer visited the box in the street. We have on-curb parking in our street and unfortunately for us the network box is INSIDE a parking space and it has been hit and knocked over several times. 

Please advise if the Network Status stats and logs look good and if we can get an engineer to look at the box in the street.
