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:

Intel wireless 8260 - unclaimed network should have the answer to this problem, but if it doesn't tell me and I will check.

  • I tried following https://askubuntu.com/questions/693109/intel-wireless-8260-unclaimed-network, but failed.

    What do I need to do instead of: Please download this file to your desktop: https://www.kernel.org/pub/linux/kernel/projects/backports/2015/09/23/backports-20150923.tar.gz if using a lter version of Ubuntu. I'm on 20.04.

  • make clean results in: Generating local configuration database from kernel ...Kernel version parse failed! – Arnulf RUpp Jul 10 '20 at 13:13
  • https://help.ubuntu.com/stable/ubuntu-help/net-wireless-troubleshooting-initial-check.html.en could be a helpful link but also check that the wireless switch is in the on position. – nochintator Jul 10 '20 at 18:23
