Follow the instructions for LTE modems.  A 5G modem is pretty much the
same wrt drivers and basic management.  At least for Qualcomm based
modems on a USB bus.  Have no experience with anything else.  The Intel
and Huawei modems are competely unknown to me, and most likely
unsupported for the forseeable future.  And I'm also blank on the magic
of Qualcomms PCIe interface. Qualcomm did work on a driver, but it's
been a long time since I saw any update on that.  I guess no one cares
enough.  SuperSpeed USB is fine for most users for now.

Anyway, several X55 based modems are already supported out of the box in
OpenWrt master.  There is no need to reinvent the wheel if you are using
one of those.

You may obviously decide to implement your own alternative solutions,
like using some vendor software. But that will limit the user community
severely. At least until the solution attracts more users.  And
community support depends on users, which I believe is something you
should consider since you have ended up in this forum.  You are unlikely
to find anyone here who have any experience with your particular vendor
software version.

Personally, I am happy to give advice about anything regardless of
experience.  But the quality of that advice is probably a tiny bit
better when it is based on something I've tried myself.  Or maybe not?
Is probably bad in any case.
