Funny coincidence. I've just spent the last hour on the phone with Comcast support asking them to disable the "xfinitywifi" my router is broadcasting and when it was all over decided to unwind and read some NH... And see this!

For anyone who needs to, call "1-855-845-6834" and ask them to disable the "xfinitywifi" hotspot on your router.

This will save you the 4 transfers, giving your info many times, and listening to the upgrade options you don't care about. It may also save you from the $70 support they'll try to charge you (should you choose to agree), and possibly one redirect to a number that no-longer exists (all of which I just went through).
