We have our first mangoh yellow successfully connected it to Octave and updated the firmware. We have built an image from the mangoh github repo and installed it. We have built the helloworld samples from the tutorials and installed those. Sometime in the process, however, we lost the connection to Octave such that it no longer connects. I have tried reverting back to mangOH-yellow-wp77xx\_0.7.0-octave.spk and that doesn’t fix it. When I run ‘legato version’ I get:

19.11.3-1-g8c030edad\_7a604bcf1664f91cfbfb7013e7cda281

but it is strange that my helloWorld app is still there. I must not completely understand where apps live compared the spk image that I’ve been installing.

When I run ifconfig, the rmnet0 is not claiming an ip address:  
rmnet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

The output of ‘cm radio’ seems ok:

root@swi-mdm9x28-wp:~# cm radio status  
Power: ON  
Current Network Operator: Sierra Wireless  
Current RAT: LTE network (LE\_MRC\_RAT\_LTE)  
Status: Registered to a roaming network (LE\_MRC\_REG\_ROAMING)  
Signal: Very strong signal strength (5)  
PS: Packet Switched Registered, home network (LE\_MRC\_REG\_HOME)

Here is more:  
root@swi-mdm9x28-wp:~# cm data  
Index: 1  
APN: iot.swir  
PDP Type: IPV4V6  
Connected: no

Tried running ‘cm data connect’ and this is what I get:  
root@swi-mdm9x28-wp:~# cm data connect  
Setting up profile 1  
Connecting … ok  
Checking if device ‘rmnet\_data0’ is up … ok  
Routing inet … ok  
Updating /etc/resolv.conf … ok  
Testing connection … failed

How do I get my mangoh yellow back to auto connecting?
