I assume it's the upside-down "Y" thing (formerly) made by Cisco?

They have had a number of issues.

At one point, they cross-checked the address with the GPS coordinates, and if the GPS coordinates weren't within 1/4 or so of the address, they would refuse to connect. I thought they fixed this, but really don't know. Addresses in our area are very haphazard, and the "location" of the street address is often off by more than a mile (I think our street address is almost 2 miles off the mark).

If you are NATting in the SM, there are some issues WRT address resolution.

Older Canopy firmware (prior to 13.4) either breaks (or doesn't break) packets on boundaries that are "acceptable" to the AT&T femtocell.

We have had the best luck by putting the SM in bridge mode.

They also take a horrendous amount time to "sync up" with the network (sometimes hours). Make sure they are close to a window so they can obtain a GPS fix.

Did AT&T make some change to their microcells? We have customers callin in alot with their microcells no longer working. I initially thought it was because we moved some customers to some IP space we borrowed from our upstream. But we have had a couple that didnt change and one that actually is triple NAT.

We dont support these things at all, we just make sure their on a public and tell them to call AT&T to recommend a compatible router and provide configuration instruction so its not a support issue im concerned about, just curious if others are seeing this.

We did change from static routing to OSPF, but I cant imagine that would have had any impact since the customers are still traversing the same path
