Model: New Dell XPS 15 7590
OS Version: Ubuntu 19.04
Kernel Version: 5.0.25/5.1.21 (I've tried all below on both versions, neither resolves the issue)
The Problem:
Ubuntu does not detect a Wi-Fi card attached to the computer, seemingly because of driver issues. lspci
says that the Network Controller is an Intel Corporation Device 2723 (rev 1a)
, and lshw -c network
confirms that it is an Intel Corporation device that is marked UNCLAIMED
, implying a driver issue of some kind. rfkill
shows a working Bluetooth device, but doesn't list anything for Wi-Fi.
Interestingly, the Dell website says the card is a Killer Wi-Fi 6 AX1650 (2x2), and it functions well on the Windows install in this machine (after installing appropriate Killer drivers).
Attempted Fixes:
I've scoured the internet for hours. What I've tried:
- Upgrading to Kernel version 5.1 (Problem Persisted)
- Upgrading to 5.2 (Persisted, later uninstalled 5.2)
- Forcing reinstall of
linux-modules-extra-$(uname -r)
, which errored out on all kernel versions. On 5.0, it fails to installbroadcom-sta-dkms
, as the module, for some reason, tries to initialize installation for kernel version 5.2.8, despite uninstallation of 5.2. On 5.1 and 5.2,apt
can't find the package. - Purging
bcmw-kernel-source
and installingubuntu-restricted-extras
. Fails for the samebroadcom-sta-dkms
issues as above. - Everything else I've come across so far. Nothing has worked, and I am officially lost.
Any ideas? Is this Wi-Fi card just incompatible with current Linux?
