MAC OS El Capitan issues with AT&T Aircard 340U

Good Afternoon, I use my MAC for business and this morning after upgrading to the MAC OS El Capitan latest release I am no longer able to use my Aircard 340U. It just keeps restarting the Aircard with the ATT logo and does not offer the connection or launch the software control center. Can anybody help? I do not want to revert my OS if I don't have too. Thank you to anyone that can help.

        Hi DarrenM -

         

        I have the same problem as the original poster.  I downloaded the recommended driver, but there is no change for me.  The Airbeam device restarts constantly and the AT&T All Access application indicates, "Modem Unplugged".  When I looked into the contents of the .pkg file, it seems it is from May, 2015, a good five months before El Capitan.

         

        Is there a manual uninstall process for these drivers in order to "clean" out potential left over old drivers and install this updated driver?  Is there another version to be released soon?  This is pretty much garbage that a month after release, I cannot use a product which my company is paying a monthly service fee to a wireless provider.

         

        For anyone else that stumbles upon this thread, is this firmware working for you on 10.11.x?
