Yes but doesnt work
Not on dual boot. only endeavouros
fastboot is off ?
Maybe try some more options for the WiFi card in /etc/modprobe.d/iwlwifi.conf
options iwlwifi 11n_disable=1 swcrypto=0 bt_coex_active=0 power_save=0
options iwlmvm power_scheme=1
options iwlwifi d0i3_disable=1
options iwlwifi uapsd_disable=1
options iwlwifi lar_disable=1
This would be the next thing to try, imho.

The Intel 3165 uses the same firmware as the 7265
You can check what it shows.
sudo dmesg | grep firmware
Edit: As @anon11595408 suggested you may want to try the lts kernel.
