Awesome… this blog post worked and solved my problem. 1st I updated the firmware from Sierra wireless, then updated the connection settings. Problem resolved. Thanks much for saving me previous time.

I’m using Windows 7 64-bit beta 1.

Thanks dude! Worked great. I did hit the same issue as Ranada/#19 in that the ATT Connection manager won’t let me type in wap.cingular. My fix was to uninstall ATT Connection manager and download the generic 3G Watcher program from sierrawireless.com and it lets you enter that and works like a charm.

Do you know what profile works for t-mobile or boost mobile?

The link to download the firmware was not working so I skipped that step. I followed the rest of the instructions and the card worked great when I tried it the first time. I’m using the card right now while posting this comment.
Thanks for you help.

It happened to me too. I found it only remove all data in Access Point Name field and leave it in blank. It works for me now.

Tried your fix, but when I type in wap.cingular and click next it tells me to choose a different APN. It wont let me use that one. What now?
