XFINITY hotspot + VPN
I have had no luck getting Encrypt.me (formerly Cloak) to work on Xfinity's hotspots. In fact, it's been blocked on all of the networks I've tried in the past few months. Maybe it still works at places like Starbucks, but I usually don't bother trying because I won't be there very long. On the other hand, at conferences and off-site meetings, VPNs are useless.
I'm thinking of cancelling my subscription as VPNs seem to be useless for public but authenticated wifi now.
