Modem came yesterday, plugged it in, gave VM a call to register MAC address - which involved the girl having to call me back after 5minutes because they had a new system in place ... - but after about 5mins it did start to work, the registration page wouldn't come up for me, but i think it was cus it was connecting through my router, so plugged it in directly and it works a treat

No more cut-outs hehe.
FYI, its the Ambit 256 model
