This issue has followed me over the years, every once in a while I resolved it, but I never found the one solution.
Most of the times, the issue is a missing wireless firmware, in the current instance b43/ucode16_mimo.fw.
I usually create the install drive with dd if=./debian.iso of=/dev/sdb
.
Now in the past, I've tried to find the firmware file and copy it onto a USB flash drive. The first issues were:
- I couldn't find the exact, required file (e.g. b43/ucode16_mimo.fw). I believe that this included the missing firmware file once, but didn't work this time.
- The install medium is read-only, so I used a second USB drive, where I don't know if it's accepted or not.
- I have no clue where to place the files on the USB drive.. is it in
/
,/firmware/
,/lib/firmware
or somewhere entirely else?
Lately I failed there and wasn't able to add the firmware during the setup, that's where I found the images with firmware included, which felt like a holy savior at this point.
But that didn't change a thing, I was prompted with the same error about missing firmware again.
TL;DR and my question:
How do I correctly add missing firmware during a Debian setup and where do I find the suggested firmware files?
