MAC address does not show up on the telco's ARP table caches |

Hi,
I am using as ISP that uses the telephone/DSL network from the local
telco to provide their clients with broadband/DSL access (they do
provide a better/marginally cheaper service).
The thing is that I am repeatedly (and way too often) kicked off the
net in ways that even my ISP tech suppost considers to be "very
strange"
I know I am connected to the Net because if I run ethereal setting my
card on promiscuos mode (I am connecting to the Net directly), I can
see the whole traffic of what is going on on my domain. I must be a
heck of a guesser to make up an ethereal ethernet traffic log.
They have told me things like:
._ your MAC address does not show on the telco's cache.
._ your MAC does temporarily show on their ARP table cache
sometimes(?!), but as an imcomplete address
._ their ARP tables also show lots of different MAC addresses assigned
to you that are actually not yours
Also my ISP has a procedure to refresh your NIC's MAC addresses that I
have used to no avail. I have even tried using dirrent NICs on X86
boxes and even a Mac.
What could be the 'technical' reasons why this could be happening?
Thanks
