There is chance that your sim card is not working.

In cm data command it shows it connected.
root@swi-mdm9x28-wp:~# cm data

can you try other sim card and operator?

Hi jyijyi,
Its working for me.

Thanks :slight_smile:

sir , my data connection is not stable,
It is connecting to internet but it automatically dissconnects .the time difference varies it is not same. Some time only 2 minutes other time 5 or 6 minutes ,
i am connecting by below command

root@swi-mdm9x28-wp:~# cm radio
Power: ON
Current Network Operator: airtel
Current RAT: LTE network (LE_MRC_RAT_LTE)
Status: Registered, home network (LE_MRC_REG_HOME)

i have not running any extra apps i have generated .ubdate file from below source code for yellow board through leaf manager “GitHub - mangOH/mangOH: Primary mangOH git repository”
where should i look into

11

Is this caused by your .update file?

If just with official firmware, will it have this problem?

12

sir i have updated firware from below link “Modem firmware ( Generic)”
https://source.sierrawireless.com/resources/airprime/software/wp76xx/wp76xx-firmware-release-16,-d-,3-components/#sthash.bhACNisj.QD6WbLMH.dpbs

and i have generated my own yocto image by 16.3 source file

13

You did not answer the question …

Is this caused by your .update file or your yocto image?

If just with official firmware, will it have this problem?

14

sir i have not tested with it sir,i don’t know about which firmware you are saying

15

Which module are you using?

16

i am using wp7608 module

17

Then you can test with r16.3 and r13.1 to get more clue

18

should i use generic fiemware only or other type i should try

19

You can use the generic one of r13.1 first

20

yes sir , it is working fine know

sir it is working in r13.1. not in 16.3
