ATT Beam 340u


Recommended Posts

.The AC340U is a LTE USB modem for AT&T and works as a regular modem, meaning it does not offer routing capability nor does it support NAT (Network Address Translation) nor have a Web UI. Its default mode is to support Auto Connect in the firmware, as well as has Identity Morphing to support native Windows 8 MBIM (mobile broadband interface model). Linux does not work with this Windows 8 MBIM Identity Morphing feature, so you need to turn it off for using the device in Linux.

MBIM has been disabled and I installed the Gobi-Net and Gobi-Serial drivers for Linux to use the aircard. Now I would like to use the aircard on my pineapple. Could I get pointed in the write direction for this? I've searched the forums but failed to find a decent answer on how togo about this.
