If it's an ADSL service then there should be an Ethernet port on the modem/router and assuming your mum's PC has an Ethernet port you should be able to access the internet immediately - no SP required.

BUT, for security reasons, an immediate ugrade is recommended - just make sure system restore is turned on.

I'd send you a PM... If it helps, I'm on the Central Coast (NSW).
