You may have misunderstood me: the mifi router is for sure ok. The problem is the AT&T service. The
consumer service gives you an internal IP number, meaning it can't be reachable using port forwarding
from the outside (this problem is called "double NAT"). You will find several negative stories on AT&T if
you search this forum, also concerning the same problem for their U-verse service. Apparently you can
get a true, routable external IP number by paying a lot more money for a business account.
Anyway, you are welcome to buy it and see if it works. Just warning you
