The MAC address of my NTL 250 cable modem is XX:XX:XX:XX:XX:XX.
Admin Edit (Chris T): It is unsafe to publish this information on a public website.
I understand that it is the service tech. who should escalate this but of course as the problem is very intermittent it typically never happens when a tech is present on site...
As I said in the (admittedly rather long and rambling) initial post I actually had a visit from the senior area tech who checked things out (it was all working at the time), and told me it was not a problem at my end. He then went off to check things out from the network side. He rang back 2 days later and spoke to my wife and gave some story about this being due to traffic shaping, but frankly there are many things that don't check out on that front (wrong time of day, we never reach the TF cutin limits, service stops rather than going slowly, etc.). Of course there is no way to reach this guy again since no one will admit to having any way to get a message to him or a 'phone number for the engineering dept. (apparently they are always contacted by telepathy or something it seems...)
What I was hoping for is that the network guys could monitor my MAC address for a few days until the problem had occurred a few times and then see hat the trace showed. Seems that is not something anyone wants to do...
Sigh
