US 3G (AT&T) Connection (Exchange) Woes

[johnpwu]

I just got a Diamond, put in my AT&T SIM, and let it automatically set up the connection for me. It set me up using wap.cingular. This delivers very fast internet, BUT, it won't stay connected to my exchange server for more than a few minutes (I have it set to sync as items arrive, and leave activesync always open on the phone). I tried doing a hard reset, then manually entering my settings (isp.cingular, ISPDA@CINGULARGPRS.COM, etc.) which works for exchange (it stays connected) , but when i run speed tests I end up only getting about 200k. Any ideas?

anyone with the DIamond on AT&T

Is there anyone else out there with a Diamond on AT&T using an exchange server connection? If so, would you mind sharing your data connection settings?

I am using the stock setup for AT&T. All I had to do was turn off the proxy server and it works fine.

do you use an exchange server connection? When you say you use the default setup, do you use wap.cingular or isp.cingular?

You shouldn't see either if you let auto setup configure the exchange server for you. The auto setup will check proxy server for you in the process. You should then be on MEdia net
(modem tab), with wireless.cingular appearing in the dimed box for name of the proxy server.

found the setting, I changed it and will report how it works. Thanks

(modem tab), with wireless.cingular appearing in the unchecked/dimed box.

the auto setup will turn the proxy for medianet on, since it's needed for it to send mms.
