Use a Qwest Actiontec model w/ Embarq service?

Greetings.

I have a 3-4 year old Qwest Actiontec wireless modem (Model GT701-WG) that I'd like to use as my main router, but I don't have Qwest service anymore -- now using Embarq/CenturyLink. Does anyone know if this is possible? I figured I could just download an updated driver from the Actiontec website, but since the modem itself is labeled 'Qwest', I wasn't sure if the cross-polination of wireless companies would work.

Thanks for any help!
