LTE - Modem Works But Cannot Ping

[tom]

@derrick0799 Do you have WiFi connected? If so, try disabling it with ifconfig wlan0 down and seeing if you can then ping.

Also, can I see the output of route -n?

Same for you @vmassague something to try.

@derrick0799 Looks like APN is setting correctly so that's good

@tom after disabling wlan0,
/ # ping 8.8.8.8
connect: Network is unreachable

/ # route -n

@derrick0799 What does ifconfig show?

@derrick0799 Is that the output after running voxl-modem-start.sh?

[tom]

At that point, you should be seeing something similar to:

wwan0     Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

@tom I think my problem was that the wifi was connected when I ran the voxl-modem-start.sh
Now that I am connect with adb everything started working when I re-ran voxl-modem-start.sh. It is pinging as it should.

Thanks @Tom

@derrick0799 Great to hear!

[vmassague]

Problem solved for me too! I think it was also the wlan0 being up. Thanks a lot for the support @tom

[tom]

@vmassague Awesome!
