    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
    AC775Panther 200411081700.dmg**

    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.

    write "AT+CGDCONT=1,\34IP\34,\34APN\34\13"

    Replace the APN in the line above with the word proxy as below.

    write "AT+CGDCONT=1,\34IP\34,\34proxy\34\13"

    Close file.

    After editing and saving the script, It needs to be copied to /Library/Modem Scripts. In the folder /Applications/Utilities/AirCard7X0 you will find 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.

    Now open the System Preferences utility.

    Select Network.

    Under Location pulldown button, select Automatic
    Under Show pulldown button, select Network Port Configurations

    Now check the box next to PC Card Modem. Press Apply Now.

    Now go back to Show pulldown button and select PC Card Modem.

    Select the Modem tab. Under the Modem pulldown button, select the Sierra Wireless AirCard 7x0. Press Apply Now.

    Now select the PPP tab. Under Account Name, type in guest. Under Password, type in guest. Under Telephone Number, type in *99#
    Press Apply Now.

    You are now ready to connect.

    Press Dial Now...

    A new window labeled PC Card Modem will pop up. Press Connect. You will then see the progress of the dialup in the Status section of this window. At this point, you should be logged in.

    Be sure to read the Introduction and Normal Use section of the included AC775 for Panther Installation Guide.

    You might want to copy the acc775reload script to your dock since the card is no longer recognized after rebooting the computer. Alternatively, you can add this script to your Startup Items under the Accounts section of System Preferences.

    Under the PC Card Modem settings in Network, System Preferences,

    select the PPP tab, and change the following PPP Options...
    Turn off Prompt every x minutes to maintain connection
    Turn off Disconnect if idle for x minutes.
    Turn off Send PPP echo packets
    Turn off Use TCP header compression
    Turn on Use verbose logging

    next select the TCP/IP tab, and then the Configure
    Turn off Configure IPv6

    lastly, select the Modem tab,
    Turn off Wait for dial tone before dialing

    Press Apply Now to save changes.


    By the way, I found some hints for setting up the Sierra 775 in the following webpages:

    This is Ross Barkman's GPRS info page. You can find APN, userids, and passwords here for various networks.
