  1. While the EM7430 works with my kext. (I guess the product ID needs to be adjusted still). The EM7455 seems not. What I did:

     

    Wrote the kext for DW5811e / EM7411 according to the correct PID & VID attached above. Which after it appears on WANN section (location id show xxxxxxxx / 0 as others also have in their screen). Then with the correct APN the error shows:

    So I updated the firmware and all config settings using LIVE UBUNTU CD 18.04 with:

    His autoscript is perfect for updating FW, configuring the whole card according to our needs & sets the PID/VID to generic to bypass any vendor locks.

     

    Whilst I updated the kext to reflect all MC/EM7455 cards PID/VID (Lenovo / DELL / Generic). Still the error "Network Connection ... " shows. Please also see the location difference:

    NOTE the firmware: SWI9X30C_02.08.02.00 r5428 CARMD-EV-FRMWR2 2016/01/06 20:38:53

    While at!priid? shows the updated firmware:

    SWI9X30C_02.33.03.00_00_00_GENRIC

    So I manually check the connection using COM port:

    screen /dev/tty.wwan 115200

    screen /dev/tty.wwan 115200

    Which after I'm able to manually connect using at commands. Any ideas where to look? Perhaps it is the interface mapping?

    				<key>InterfaceMapping</key>
    				<dict>
    					<key>0</key>
    					<dict>
    						<key>name</key>
    						<string>wwanDM</string>
    					</dict>
    					<key>2</key>
    					<dict>
    						<key>name</key>
    						<string>wwanGPS</string>
    					</dict>
    					<key>3</key>
    					<dict>
    						<key>name</key>
    						<string>wwan</string>
    					</dict>
    				</dict>
