Micro Cell fails to activate


Micro Cell fails to activate

I have an interesting issue with the microcell. ATT has not been much help. I have the cell connected to my network and my network device config is as correct as I know to make it. Activation fails, just sits with the singal bars light flashing. So I use network packet analyzer and watch as I restart the cell. After GPS lock, the cell tries to contact on port 443. This I expected as it was indicated as an early step in the process by some posts I read. However, the attempt to connect to this IP address times out. There is no reply from The cell will retry this address and, which is apparently shutdown as I get an ICMP for that indicating it is blocked on purpose. A tracert of shows the route going into series of att servers and finally to and then the tracert times out.


Now it seems if this connection is not made, activiation cannot proceed. ATT ignores this and runs me through all kinds of other stuff before telling me my connection speed is too low and that is why it fails. Really?


ATT did confirm that is the correct IP but thats about all I got out of them.


Any ideas on why I am not getting any further than the failed connect to

I'm out of town with limited access but like I said, the MicroCell is a dumb device in that the four ports and the other router conflicts listed in my Guide must be met. Any other alteration or addresses used will probably not work. The MicroCell needs to create its own secure VPN to the AT&T mobility servers and with as simple of a connection as possible. Either directly to the modem or router. If the 3G light is blinking green, then connection has not been made which could be due to one of the mandatory conditions not being met, line quality conditions, etc.
