This is likely the same problem everyone else is having with AT&T right now. All router, many plans.

One proposed workaround is using a VPN with a port other than 80 and 443.

Also, this likely only affects people that have hit 22GB of usage in the current billing cycle.

Good luck to us all!

Any chance we can mark this again as unsolved? The VPN is a workaround, not a resolution. It may be sufficient for the OP but the problem is very much still there.

Thanks!
