Started Unicast Maintenance Ranging - No Response received

Hi,

 

I am getting periodic disconnects in the Glasgow area.  The superhub router/modem logs are full of the following type of errors each time the connection goes down:-

I have had an engineer out and he replaced a splitter and some cable but the problem persists.  Are there any known issues in this area or is this a site specific issue?

 

regards,

Gavin
