So I assume that the running system finds the modules, loads them and
also some firmware for them (perhaps even rtl8723defw.bin?), yes?

If so, then it's worth knowing what the installer found. The file on
your installed system /var/log/installer/hardware-summary has its
lsmod output in the third section, after lspci and usb-list.

If they're found, then /var/log/installer/syslog (considerably larger)
should show the module (the rtlNNNN one) being loaded, followed by the
firmware. If you saw no messages on the console, then it's perfectly
possible that the module and its firmware were found and loaded
successfully, but they just didn't make the wifi work, which would be
a completely different bug.

If you've time to spare, you could of course retry the installer
*without* the firmware on a stick, deliberately provoking the module
(if it gets loaded) to complain. These "forensic" observations would
narrow the scope of potential bugs.

Cheers,
David.
