[Solved] Unable to get 4G connection on pc engine APU3a4

[unam]

Hello,

I'm actually running OPNsense 17.1.4 on a pcengine APU3A4.

I choose this device for its 4G/LTE advantages.

To get 4G/LTE working fine, I bought a SierraWireless MC7304 card and tried to get it owrking with a Free Mobile and Bouygues sim card unsuccessfull.

I followed this documentation : https://docs.opnsense.org/manual/how-tos/cellular.html and did exactly the same as specified inside, especially the device number specified here : https://docs.opnsense.org/manual/mobile_wan.html (uaUx.2).

Here are parts of logs from point to point logs :

Code: [Select]

Apr 27 12:09:30 ppp: [wan_link0] Link: reconnection attempt 49 in 4 seconds

I do not know *bsd systems very well and where to find specifics logs.

- Where could I find debug informations ?
- Can I turn on debug on lte connectivity or anything else ?

Thanks for your help and answers.

Cheers,

Ok, I found an answer here : https://forum.pfsense.org/index.php?topic=86064.150

- As mentionned, I had to add &F0E1Q0 +CMEE=2 in front of Iinit string text box
- I also had to delete PIN code from SIM card, then after a reboot, connectivity seems ok !
