is wrong.
Switch your modem into the composition with comm ports, switch it from Dell to Generic, update the firmware - all that has nothing to do with OpenWrt though.
Then set it to QMI mode and follow the guidelines from https://openwrt.org/docs/guide-user/network/wan/wwan/ltedongle
There're other options available as well - MBIM instead of QMI, ModemManager as a proto, etc.

Hi,

ok, the modem is already in MBIM mode....

may you write a right configuration?

there are no information about MBIM mode....

tkns!

There're a few good guidelines in the document I linked, including this one:

Install the package luci-proto-qmi using Luci (System → Software ) and configure the modem using LuCi (Network → Interfaces ).

You will need to switch to QMI (as I advised you earlier) in order to use this package.

There may be useful information in this thread about mbim:

Yesss..... not so easy.... but YES!
