We3926 / WE826-T2 Cell Settings

Does anyone know what dial mode is on thsi 4g router. I can not get it to connect to lte network on tmobile or att

The choices I have are
PPP
Gobinet
QMI

Seems like a nice router just need it to connect via lte.

WE826: Usually with Quectel EC-25. Use PPP (3g) for it.

Should be what protocols could be used by the modem installed in this router?

Read the spec for the modem, for the popular mPCIe modems you will probably see QMI and/or MBIM there. Both are supported by OpenWrt. With EC25 use QMI. Do not use PPP. I suggest to use this OpenWrt-based firmware, especially if you want to avoid manual modem configuration.

I agree with AndrewZ you should use the firmware he recommended Rooter. I own this router and it is very easy to set up and use if you don't want to do anything fancy.

As with all things Linux seemingly, fancy is complicated.

I find this to be an invaluable resource for this router. The forum answers a lot of questions.
