Critical(3) StartedUnicast MaintenanceRanging -No Response received Every 10 Mins!!

Hi

I've had previous posts on this issue but with no means of resolution

The Problem

My modem resets itself up to 30 times a day!
Trying to MMO or Work from home is practically impossible
I'm losing the will to live

What I've done to try and resolve the problem / ruled out

Bought a brand new Router
Contacted Virgin Technical Support at least 10 times
Had Virgin fit a brand new 256 Modem
Had a dimmer fitted
Tried a direct connection from modem to PC
Tried 3 different PCs
Used my PC on 3 different networks
Tried using a direct coaxle connection from wall to Modem
Used different combinations of cable lengths, splitters and dimmers to try the modem with the following Download Power levels:
+2-5
+4-7
+9-13
+13-15

I have tried all of these things. But the reason in my opinion is:
My CMTS trying to upgrade my modem!

The following log appears in my modem log at intervals of as short as every 7 minutes every single day:

My friend has a virgin broadband connection 6 miles away with no problems what so ever. I looked at his log and the last time he had this message was over 2 years ago! I could live with that no problem!

I have an engineer coming to look tomorrow. What do I tell him!!!!!

please please help (I'm even writing this in notepad in case my connection goes again!!)

FYI. It is no coincidence that every single time I lose my connection, the UNICAST maintenance has started which I can see in my event log (down to the very second!) including this second in fact. It's doing it again as we speak!
