Hello again,

About the AT debug information, what means :
"RRC State: DISCONNECTED "

How can I fix that please ?

Hello,

First of all, thank you to the "LTE team" for the time give by amazing 4G router passionates and professionals .

Today I try to finalize the connection with the WE826 associate to MC7700, with GodenOrb we826-GO2019-03-10 version.

Something strange happened when I was trying to adjust ...

Hello,

Finally after checked, the EM7455 is badly detected under a xubuntu system, that confirm that the card should worked. The computer is an old atom which was working under XP with a M2 Pcie adaptor.

Hello again,

sfx2000 precised me on another forum :

Hi,

I integrated the 4G card EM7455 before flash the system OpenWRT in a WE826 16M router.

4G cards pecifications :

Several people use that configuration on wirelessjoint.com, so I guess that should be possible.
The good exercise at this step, because we're at the third page of a "Rrutl" post, is maybe a better formulation for a new post title ?

For test the material, I tried to plug a Huawei E3276S-150 LTE (4G) USB Modem but the system isn't recognize neither the Key specifications on Modem/debug information.

So I guess I've to try to find the process to flash the card EM7455 after flash the WE826-T with Sierra ubuntu programs ?

Understood Jim.

If we fix the glitch and if you're agree for this post I'll done an equivalent tutorial at :

Hello jmattivi,

Unless if I mistaken, you don't precised if you change the power supply from "12V 1A" to "12V 2A" ? Because I guess the Sierra EM7565 has an equivalent power consumption than the Sierra EM7455.
