Correction: I have the same display issue, but WiFi IS working on Dell Precision 5520, Unbuntu 20.04.
My apologies, there was an unrelated DHCP issue, but this display problem got me going down the wrong path to fix it. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ubuntu-drivers-common in Ubuntu. https://bugs.launchpad.net/bugs/1859308 Title: software-properties-gtk erroneously reports that certain Intel wireless adapter cards are not working Status in ubuntu-drivers-common package in Ubuntu: Confirmed Status in ubuntu-drivers-common source package in Groovy: Confirmed Bug description: On Ubuntu 20.04 (development branch), as of today, Additional Drivers (software-properties-gtk 0.98.6) reports that the device "Intel Corporation: Wireless-AC 9260" is not working, and suggests using a manually installed driver (cf. screenshot). However the device is working correctly: * lsmod | grep iwlwifi, lspci -v, lshw, dmesg | grep iwlwifi all show that its driver iwlwifi is in use * ls /lib/firmware/*9260* show that the appropriate firmware files are present And I am indeed writing this bug report connected to an ac (5 GHz) wifi network, where I can verify a ~130-160 Mbps download speed, so software-properties-gtk shouldn't report the device as not working and suggest manually installing a driver. Not sure why it says so?
