I found a post with a similar issue for Intel(R) Dual Band Wireless AC 8260 chip set, but cannot follow the recommended steps for Ubuntu 20.04: Intel wireless 8260 - unclaimed network

It suggests compiling the driver for a different pci.id: (IWL_PCI_DEVICE(0x24F3, 0x1130, iwl8260_2ac_cfg)

Now make defconfig-iwlwifi > fails with: Generating local configuration database from kernel ...Kernel version parse failed!

Which driver do I need to use/modify for Ubuntu 20.04?

Diagnostics:

  • It seems to be working: Kernel driver in use: iwlwifi Are there any clues here? rfkill list all or: dmesg | grep wlp
