I run into a well-known problem that was actually already widely discussed on the web. However, I unfortunately could not solve the problem yet.
I recently replaced the Wifi network adapter into a new one, Intel(R) Wi-Fi 6 AX210 160MHz, in a Dell Rugged 5414 laptop, several years old.
I'm still fairly new to Linux/Ubuntu and appreciate any assistance.
root@laptop-02# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.1 LTS
Release: 22.04
Codename: jammy
The network adapter was correctly recognized by the system:
root@laptop-02# lspci -knn | grep Net -A3
01:00.0 Network controller [0280]: Intel Corporation Wi-Fi 6 AX210/AX211/AX411 160MHz [8086:2725] (rev 1a)
Subsystem: Intel Corporation Wi-Fi 6 AX210 160MHz [8086:0024]
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi
However, the system shows the WLAN function as switched off. Wireless networks are not displayed. The function is greyed out in Ubuntu.
root@laptop-02# sudo iwconfig
lo no wireless extensions.
enp0s31f6 no wireless extensions.
enx10050197f9a6 no wireless extensions.
wwan0 no wireless extensions.
wlp1s0 no wireless extensions.
The first errors are displayed here:
- reporting RF_KILL (radio disabled)
- Direct firmware load for iwlwifi-ty-a0-gf-a0-73.ucode failed with error -2

The driver seems to be ready, but it still need to get the firmware for the chip, that doesn't work:
root@laptop-02# sudo dkms install backport-iwlwifi/8400
Kernel preparation unnecessary for this kernel. Skipping...
Building module:
cleaning build area...
'make' -j4 KLIB=/lib/modules/5.15.0-46-generic...(bad exit status: 2)
ERROR (dkms apport): binary package for backport-iwlwifi: 8400 not found
Error! Bad return status for module build on kernel: 5.15.0-46-generic (x86_64)

I downloaded drivers from here: https://www.intel.de/content/www/de/de/support/articles/000005511/wireless.html
I mainly followed this post in the procedure (answer 3): Ubuntu 20.04 LTS driver Intel Wi-Fi 6E AX210 160MHz
Many thanks to everybody for any support. Please keep in mind, I'm still a beginner with Linux ;)
