Just reading this somewhat interesting article...

Author is having a problem with his adsl line, and is speaking
with a US company called verizon.

What actually happened here? It sounds like he was moved from one
access concentraitor to another. If possible, I hope its something 
that Telstra would be able to do for us in the event of a PP -lockup ;)

Bah. I would like to more about this router. I have not heard of that
happening with an AC.

Yes, but should a client-set MTU setting really affect the Access Concetraitor 
in this way?
