I live in Los Angeles, and I'm experiencing very odd connect problems.

I have both a Cingular Laptop connect card, and a Cingular 8525.
Mostly i'm on edge, sometimes 3g/hsdpa. From anywhere in the world i
can ping 66.102.136.161 except on my cingular network. Sometimes it
works and most of the time it doesn't. It seems I can't access
anything on the 66.102.128.0/20.

From what i can tell of traceroutes, its not making it past cingular's
filters or firewall.


Is that the only IP you can't ping? Or can you not ping/traceroute in
general? I myself use T-Mobile's EDGE service in Chicago, and can ping but
cannot traceroute out in any functional way.
