First time post. Basically after an wifi firmware update my laptop doesn't have WiFi anymore.
When I go to "Software & Updates" >> "Additional Drivers" it says device is not working with two options (which before i remember having about 4 options for this device) -"Do not use device" which is enabled -"Using oem-wifi-intel-iwlwifi-lp1757035-4.4-dkms driver in DKMS format wrapped by dkms-helper...(open source) When I try to select this it fails.
Dell precision 5520 Ubuntu 16.04 intel 8265/8275
Verified iwlwifi-8265-XX.ucode is located in /lib/firmware
rfkill list all > no soft or hard blocks on wifi, but soft block on bluetooth.
iwconfig > lo no wireless extensions
Please let me know what other information you need. Thanks!
