AT&T USB Modem Setting

For those who have a modem AT & T, sometimes often complicated by difficult setting modem. The main problem is difficult because the modem on the switching from software installation mode to modem mode. 

Here is the way : 

First install the first watcher generic software. This software is on CD which include when buying a modem AT & T. 

Connect the modem on USB. Continue to install the drivers as well as AT & T communication manager. 

Well now your modem is in software installation mode. To be able to use it to access the internet, you have to switch from software installation mode to modem mode. 

For the switch of the software installation mode to modem mode, open the start menu then all programs, locate and select Sierra Wireless TRU-Intall. 

After click the TRU-Install, will be out Notification "Device is in software installation mode. Would you like to switch the device into the modem mode? "Click ok. 

But if not successful. Modem did not want to switch from mode to modem software installation mode. How is the solution? The solution is to restart your computer. 

After the computer restarted, try to re-open the TRU-Install, When the devices already on the modem mode means the modem can already switched, if not, then restart your computer again. 

Next, we set the connection, we can choose to use the AirCard Watcher or AT & T communication manager. I choose AirCard Watcher.
Open the AirCard Watcher. Click option
Click profile 

Profile is usually already out according to the card is used, the example I use a card axis, but if not there create a new profile by clicking the new profile. 

After the profile axis is clicked, the option will exit the general axis, here we can fill the profile name, username, password, apn, etc.. 

If already, we make sure that the default profile is the axis that sorted, I click the profile, then the default profile select axis.

Click ok. We're back again in the AirCard Watcher, just click the connect ... and an internet connection is ready for use. 

Open mozilla firefox or something else is up to you, and enjoy your surfing..

Good luck ... ...
