Telstra Sierra 4G wireless dongle not working with El Capitan
I use a Telstra Sierra 4G wireless dongle with my Mac Air/El Capitan 10.11.4 beta. The dongle stopped connecting last week; still fine on a PC. Telstra told me "not their problem" and to contact Apple. Any suggestions as to where I can find a software patch or other workaround? Thanks
MacBook Air, OS X El Capitan (10.11.3)
