Why isn't iwl linux-friendly? I bought a Dell Inspiron 13 this summer
with Windows and installed Ubuntu 19.04

$ lspci -vs 0000:00:14.3
00:14.3 Network controller: Intel Corporation Device 9df0 (rev 30)
Subsystem: Intel Corporation Device 4234
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at a11a4000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi

"iwlwifi" was installed when I installed the system and is available from "main"
