How Soon To Use TWC Wifi Hot Spots?

If I switch to TWC(Standard), from Earthlink, will I have access to TWC Wifi right away?

I'm out of town, and find TWC Wifi available regularly. I was going to order Standard Internet when back home, but if I can get access to Wifi right away, would put the order in now. Or do you have to pick up, and install hardware before having access. Any help is appreciated.
