signal available, an error message stating Error 668 caused the connection to terminate. I tried the usual problem solving of removing the aircard and reinserting it, restarting the ATT connection manager, and restarting my laptop. Nothing worked, and it continued to produce the Error 668 message. As I would rather squeeze turnip juice than call AT&T Wireless for any technical support issues, I tried A few Google searches which netted some promising results. While I am not sure exactly what fixed my problem, it is now working again without any hardware replacement. Feel https://forums.att.com/t5/Data-Messaging-Features-Internet/Error-668-or-Invalid-APN/td-p/1726911 free to try the methods below. Reinstall the Firmware If you have a different model or Mac OS, you can start at the Sierra Support website Otherwise, visit the 881 AirCard Support Downloads page for Windows Download and run the firmware application, while keeping your aircard plugged into the PCMCIA slot. Some people mentioned that installing the Connection watcher utility from the support downloads page may also help with http://www.mattsilverman.com/2008/08/error-668-sierra-881-wireless-aircard-att-3g.html this issue, but I did not need to use it. After reinstalling the firmware, I attempted to connect again but still received the same error 668 code. I then moved to this next little workaround. Install New ATT Connection Profile Using wap.cingular This is what I think finally fixed my problem, but it did not work without first reinstalling the firmware. 1. Edit connection profiles in ATT Wireless Connection Utility 2. Click the "Add" button on the profile manager window, then select "AT&T" and hit next.3. Change isp.cingular to wap.cingular, and leave all the other input boxes as is. My result looked like this: 4. Hit next, make sure both radio buttons are select to "Obtain IP Address Automatically" and hit next again.5. Give your new profile a name, I used AT&T (2). I changed the connection options window to "Automatic" from the default manual, and that seemed to work for me. 6. Hit Finish, close out of the profile manager, select the connections drop down window in the AT&T connection utility, and then select the new AT&T (2) connection profile that we just created. Hope this was some help to you. Please post in the comments if this did or did not work

Surprise, surprise! I'm having technical difficulties. Discussion in 'Electronic Connection' started by Scarecrow03, Mar 15, 2009.

I have the Sierra Wireless 881 USB Connect device through AT&T. The problem I'm having is that whenever I open up AT&T Communication Manager to connect, the software won't communication manager go past the "Acquiring Data Service" portion of the normal start up procedures. I get an error message telling me that this is due to high traffic or low signal. I looked at my event log and have found two different errors that occurred sometime on the 13th. The first one is "Error 651: The modem (or other connecting device) has t communication manager reported a problem." The other error is "Error 668: The connection was terminated." I've been all over Google and AT&T's website searching for definitions of these errors, but can't come up with anything. My Google search listed several different message boards with advice from those boards' members saying to try downloading a different software called 3G Watcher. One poster on one of those forums said it was the absolute cure-all for him/her. So I tried to follow the links provided, but get a timeout error message from Firefox. I've tried going to Sierra Wireless' site and get the same timeout message. Can anyone help me out?
