drivers - direct firmware load for iwlwifi-7265D.ucode failed with error -2 - Ask Ubuntu


i trying fix wifi in intel nuc. have intel(r) dual band wireless ac 7265, rev=0x210. driver trying load 'iwlwifi-7265d-24.ucode` according dmesg, fails error -2 (see below).

system information:

$ uname -a linux britt-desktop 4.8.0-27-generic #29-ubuntu smp thu oct 20 21:03:13 utc 2016 x86_64 x86_64 x86_64 gnu/linux  $ dmesg | grep 7265d [   14.578598] iwlwifi 0000:02:00.0: direct firmware load iwlwifi-7265d-24.ucode failed error -2 [   14.578612] iwlwifi 0000:02:00.0: direct firmware load iwlwifi-7265d-23.ucode failed error -2    $ modinfo iwlwifi | grep iwlwifi filename:       /lib/modules/4.8.0-27-generic/kernel/drivers/net/wireless/intel/iwlwifi/iwlwifi.ko firmware:       iwlwifi-7265d-24.ucode

any idea how correct firmware load? thank you

edit:

i found copy of iwlwifi-7265d-24.ucode , moved /lib/firmware. errors gone, wifi performance still low (~1/10th other older machines on network getting).

edit:

i have asus rt-ac68w wireless router , using 5ghz band. after changed wireless mode n/ac mixed (it on auto), download speeds went >100mbps. i'll keep eye on it, may have fixed it. , using firmware iwlwifi-7265d-22.ucode 24 , 23 not in directories. 

sudo wget https://github.com/openelec/iwlwifi-firmware/raw/master/firmware/iwlwifi-7265d-22.ucode
