As deloptes said, this is not related: the "missing firmware" notice
means that the operating system has detected a hardware (ath10k, that's
the WiFi) which could use some firmware (but perhaps works fine without).

The firmware itself is non-free, that's why it is in a separate package.
I think deloptes already said how to find/install it.

I don't know. There are others around here with more experience in
that than me.
