My machine is Dell Precision 3480 with Intel AX211 WiFi adapter that Ubuntu cannot recognize. I have been following instructions from closely similar situations I found but still no luck. What I have done so far is:
- Fresh install Ubuntu 24.04 (manual install of iwlwifi suggested from similar issues)
- Fresh install Ubuntu 20.04 (applied some fixes from similar issues)
- Fresh install Ubuntu 20.04 then upgrade to 24.04
- Install all suggested backport iwlwifi firmware
- Configure BIOS, turned off secure boot, etc...
I did also have similar dmesg logs from this discusion: No hope for AX211 wifi working on ubuntu 20.04?
My kernel version by the way is 6.8.0-60-generic.
Edit:
Result of some commands clearly shows the WiFi adapter
command
lspci -nnk|grep -iA3 net; dkms status; mokutil --sb; sudo dmesg|grep iwl
