Anyway my problem started around 6.00pm tonight.
The modem kept rebooting itself after connecting for about 15-30 seconds. After much testing it was only after it authenticated and was actually online.
(It seems apparently, that the modem was going into an overload)
The long and short of it is that I just happened to notice in the modem error log before it rebooted, and this line was repeated every few seconds.

A DOS attack.
I changed my IP from the members area and all is fixed (via a wireless connection). At least for the moment.
I looked up the IP details and this is what I got:
