Unable to connect using mobile router

[mbacon]

Hi folks,

Not sure if anyone can help, since this is a pretty esoteric setup, but figured it was worth asking.

I have a WE826-T2 LTE router, which has a Quectel EP06-A modem, with custom firmware ROOter (based on OpenWRT) and I am unable to connect to cellular data. The router gets an IP address, and shows that it's sending packets, but won't receive anything. As far as I can tell, the modem supports the correct bands. The SIM works in another device, and another SIM (Rogers) works in this device.

On startup, the modem appears to load an MBN profile for "Telus-Commercial", and despite settings otherwise the APN defaults to sp.koodo.com. I change this to sp.mb.com using AT+CGDCONT=1,"IPV4V6","sp.mb.com", but that doesn't help. I've tried enabling roaming (AT+QCFG="roamservice",2). I've also tried isp.mb.com.

Any ideas appreciated!

Thanks,

Matthew

Figured I would follow up on this.  It was in fact an APN problem.

I flashed the original firmware from the router and managed to get the connection working.  However, that firmware was pretty outdated, and feature poor.  I also tried again in OpenWRT with wasn't successful (I think I must have been missing a package).

I did eventually get ROOter working as well.  I had noticed that the APN seemed "sticky", it would revert any time I made a change in the UI.  One thought was that it was getting imported via an MBN profile, but even with MBN deactivated I would still get the Koodo APN.  The way I eventually fixed this was by editing two config files (/etc/config/modem and /etc/config/interfaces), updated the APN there, then restarted the interface.  This works, I'm getting decent speeds, but it does not persist through a reboot.  I've reached out to the ROOter community but they are currently stumped.  I might just write a script to update the config files and restart the interface after startup.

There are a few places I can set the APN, and I've tried all of them (including doing so directly on the modem using AT commands).

I agree that it's just a matter of finding the right settings, but I'm thinking I might want to reach out to the ROOter and/or OpenWRT community.

I checked, the router should work, but just you need to figure out the setup 

Can you do this?

1. Enter APN Info: Choose "Manual" APN and enter sp.mb.com.
2. Save and Apply: Save the changes and apply them.

I read somewhere that isp.mb.com was the mobile hotspot APN.  I've tried both.

Other options I can set in ROOter include authentication protocol (none/PAP/CHAP), username/password, PIN, PDP type (IP, IPV4V6, etc).

I've tried most combinations of those settings, and various AT commands as well.  I'll mention that I was able to send an SMS message through the router interface and receive it on another device.

Make sure it is set to IPv4

APN should be sp.mb.com, not ISP.mb.com

What other APn settings it can set?

I've tried disabling the MBN profile:

AT+QMBNCFG="AutoSel",0
AT+QMBNCFG="Deactivate"

Still nothing.
