So an update. We switched over. It was the most painless experience I have ever had with this company. They canceled the post paid service, and set us up with the NOW internet and the gateway. Got the gateway in bridge mode, it was right on the front page after logging in. My mom choose to put this under my name, so I was able to use my current Comcast account and everything. Very easy.
What told I can start and stop service when ever I needed. I also would never have to return the gateway. To be honest this is a downgrade in service, but we had 100/20 last year or the year before, so not really an issue.
