Only one problem, the router might not support bridge mode. It's possible by the time they invite me, it will, or I'll be able to get just a modem.
I don't care if it's double NAT. I don't open ports, thanks to paranoia.
The speed might decrease, and the latency might increase. The upload speed will still smoke Comcast's 5 Mbps.
In 90 days of T-Mobile internet, I won't switch to Comcast's low income internet. I don't want to give Comcast anything. Not even $10 or whatever it is. Their low income internet might have no data cap.
You know how much money T-Mobile will make once you can signup without an invitation? Lots of money. You just need a T-Mobile signal, and you have no data limit for $50 a month. Oh, and you can actually upload stuff without waiting as long. T-Mobile will be adding a lot of capacity when that happens. Comcast will probably lobby to get a law passed that says wireless carriers can't provide internet, or will have to pay tax or something.
Comcast will find a way to screw everybody. If they can't get a law passed, then they'll just charge T-Mobile a huge amount of money to use their pipes.
So, some of the internet won't be accessible, or will be really slow.
