After reading many contributions about the support of the Killer wifi card of the Dell XPS 15 9500 with the 5.10/5.11 kernels, I decided to install Ubuntu 21.04 Hirsute which provides the 5.11 kernel by default.
Everything on the laptop is working fine, great!
But not the wifi card 🙁
- lspci shows the wifi card
- lsmod shows the various ath11k modules loaded
- ifconfig or ip show only the lo interface
What is missing on this installation to recognize the wifi card?
