Sou novo no Ubuntu e uso UP BOARD com Ubuntu 16.04 instalado.
Eu instalo o iwlwifi de acordo com isto:https://github.com/HappyZ/iw_intel8260_localization/wiki/Enable-802.11mc-FTM-on-Intel-8260
Durante a instalação, após "sudo make -j4", recebi muitos "symbolmap: 00000001: invalid section".
bem assim :
symbolmap: 00000001: invalid section
CC [M] /lib/firmware/backport-iwlwifi/net/mac80211/aes_gcm.o
symbolmap: 00000001: invalid section

CC [M] /lib/firmware/backport-iwlwifi/net/mac80211/aes_gmac.o
symbolmap: 00000001: invalid section
Não sei se é um erro ou uma situação normal.
Depois de " sudo make install ", obtive
$ sudo make install
INSTALL /lib/firmware/backport-iwlwifi/compat/compat.ko
At main.c:160:
- SSL error:02001002:system library:fopen:No such file or directory: bss_file.c:175
- SSL error:2006D080:BIO routines:BIO_new_file:no such file: bss_file.c:178
sign-file: certs/signing_key.pem: No such file or directory
Mas de acordo com o guia, está tudo bem.
Quando eu reinicio, eu tenho
$ cat /var/log/syslog | grep -a iwlwifi

Quando passo pelo resto do tutorial, tudo aparece direito, exceto que o resultado final é diferente do esperado.
Isto mostra
Target: 38:de:ad:27:d0:e9, status: 4, rtt: 0 psec, distance: 0 cm
mas não
status: 0
o que significa que falhei. Segundo o autor, refiz essas etapas, mas ainda assim falhei.
Por favor, o que posso fazer?
Pesquisei tópicos relacionados e tentei algumas soluções.
De acordo comNão é possível detectar o driver sem fio Intel AC Wireless 9560 [registros incluídos], Eu fiz:
sudo apt update
sudo apt upgrade
E depois de reiniciar, consegui isso:
$ dmesg | grep iwl

Parece que não funciona.
Além disso, após a atualização, meus arquivos de firmware incluem:
iwlwifi-8000C-34.ucode
iwlwifi-8000C-36.ucode
