Excuse my ignorance here but:

I have just purchased a new Laptop ( Dell XPS M1330 ) which arrives
next week, and am now looking for a broadband wireless ISP to be able
to access the internet. Am currently considering the 3 broadband
wireless 3gb for $29 option from 3.

I am about to move house and there may not be internet access in my
new house.
Will I be able to get online with just the modem that the isp will
provide, or do I need to purchase a wireless router and find somewhere
with an internet connection already established?

I hope i haven't confused anyone here? I live in Brisbane .
