WE1326 MC7354 cannot connect to Modem

Post by jeonjin.lee »

Hi,
I have Installed Goldenorb 4-10-2019 build following tutorial on this site.
I am using AT&T simcard activated. But I haven't been able to make WE1326 work yet.
Here is my WE1326 setting.

Code: Select all

System
Hostname	ROOter

Architecture	MediaTek MT7621 ver:1 eco:3
Firmware Version	GoldenOrb_2019-04-10 ( OpenWrt 18.06.1 )

Re: WE1326 MC7354 cannot connect to Modem

It appears the GoldenOrb is detecting and communicating the MC7354 as it should--which is a good thing.

Assuming the U.FL pigtail connectors are properly installed on the correct modem antenna ports (MAIN and AUX) my bet is on the SIM Card, its activation or lack of usable service or bands, or the SIM Card adapter if one is used.

There are several AT Commands for checking the SIM Card. See this TUTORIAL.

If it is detecting the SIM Card, run the follow AT Commands and lets see what carrier firmware and version the modem is using:

Code: Select all

at!entercnd="A710"
at!gobiimpref?
Also, run this command and post the results:

Code: Select all

AT!GSTATUS?

Thank you Jim!
After reading your other post, I found that my MC7354 was set to "QMI" instead of "MBIM"
I didn't know different Sierra modems has different AT commands to change composition mode.

Code: Select all

AT!entercnd="A710"
AT!UDUSBCOMP=?

OK
Then AT!UDUSBCOMP=8 and reboot modem made it work. Thank you,
