AT&T Sierra Aircard 775 working on Mac OS X
AT&T Sierra Wireless Aircard 775 working on Mac OS X Panther using Sierra Wireless Driver
I have finally been able to get my AT&T Wireless Sierra 775 card working on my Powerbook 17.
Prior to starting, it might be worth testing the card on a windows platform using the Communicator Manager software.
First, download the driver from the Sierra Wireless website,
In the left hand margin, under Support & Download, click on the Aircard 775 tab.
Then click on the Search Knowledge Base link.
Next select the Guide to Sierra Wireless AirCard 775 for Mac OS X Panther.
At the bottom of this page, download the driver named
This includes the following files,
775.pkg, ac775reload, Panther User Guide for AC775.pdf, Panther User Guide for AC775.doc
Copy these files to your desktop.
These directions are modified and generally follow those given in the Panther User Guide for AC775.
You will need the Access point name, or "apn", userid, password, and number to dial.
For ATTwireless EDGE network,
The apn is proxy
The userid is guest
The password is guest
The number to dial is *99#
If you have Cingular or T-mobile, please refer to the webpage below.
Launch the AC775Panther package by clicking on its icon.
Insert AC775 card in slot. The status of the card will be displayed as in Figure 10 of the Panther User Guide for AC775.doc
Navigate your way to /Applications/Utilities/AirCard7X0 and click on the “Sierra Wireless AirCard 7X0” file to open it.
In the file Sierra Wireless AirCard 7x0 file, use the find command and search for APN. This will find the following line.
Replace the APN in the line above with the word proxy as below.
After editing and saving the script, It needs to be copied to /Library/Modem Scripts. In the folder /Applications/Utilities/AirCard7X0 you will find CopyScript.app.sitx. Launch that and Stuffit will place CopyScript in the same folder.
Launch CopyScript and you will be shown the dialog in Figure 15 as seen in the instructions. Press OK and your modified script with the
correct apn will be copied to where it can be used by Networking.
At this point, the computer still does not recognize the card by displaying the PC Card Modem as an option in the Network Port configurations as seen in Figure 11.
Copy the ac775reload script from the desktop to the folder
Leave a copy of this file on your desktop.
Launch the acw775reload script.
Alternatively, you can use the acc775reload.scpt file. In this case, a window labeled ac775reload.scpt will then open under the Script Editor. Press the Run button. The script will then run in the Terminal window.
You will be asked for the computer password. Type the password in Terminal window.
The result is as follows.
