How to claim Ethernet

Question

Ethernet and WiFi are being shown as unclaimed while running

What is the exact response to the terminal command: sudo modprobe r8169 Welcome to Ask Ubuntu. — chili555, Feb 21 '18 at 22:01
sudo modprobe r8169 [sudo] password for gumby: libkmod: ERROR ../libkmod/libkmod-config.c:656 kmod_config_parse: /etc/modprobe.d/iwlwifi.conf line 1: ignoring bad line starting with 'option' modprobe: FATAL: Module r8169 not found in directory /lib/modules/4.13.0-32-generic — A.Lfisher, Feb 21 '18 at 22:19
If you interrupt the boot process and, at the GRUB menu, select an earlier kernel version than -32, does the ethernet work? Also, please show us: cat /etc/modprobe.d/iwlwifi.conf — chili555, Feb 21 '18 at 22:33
will try the boot. the cat /etc/modprobe.d/iwlwifi.conf -- option iwlwifi 11n_disable=1 — A.Lfisher, Feb 21 '18 at 22:35

First of all, we see this:

/etc/modprobe.d/iwlwifi.conf line 1: ignoring bad line starting with 'option'

The file now reads:

option iwlwifi 11n_disable=1

The file was erroneously overwritten. It should read:

# /etc/modprobe.d/iwlwifi.conf
# iwlwifi will dyamically load either iwldvm or iwlmvm depending on the
# microcode file installed on the system.  When removing iwlwifi, first
# remove the iwl?vm module and then iwlwifi.
remove iwlwifi \
(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
&& /sbin/modprobe -r mac80211
options iwlwifi 11n_disable=1

Please restore the deleted content and then be certain the term is options with an s.

Next, as you found, when you boot into an earlier kernel version, the ethernet and, I assume, wireless, works as expected. Let's try to reinstall the -32 version.

sudo apt install --reinstall linux-image-4.13.0-32-generic 
sudo apt install --reinstall linux-headers-4.13.0-32-generic

Reboot. Is everything working correctly now?

sorry but back to the same no Ethernet but wireless is no longer showing unclaimed – A.Lfisher Feb 22 '18 at 01:16
When I open Wicd Network Manager it reads No wireless networks found – A.Lfisher Feb 22 '18 at 01:35
Is it blocked by the hardware switch? rfkill list all Any clues in the log? dmesg | grep iwl What does this report? sudo modprobe r8169 – chili555 Feb 22 '18 at 01:42
@chili555 Do you know why we need to downgrade the linux kernel for this to work? I have 5.3, for example, so I don't know if it would be feasible for me to downgrade (https://askubuntu.com/questions/1277732/getting-make-build-essential-and-ethernet-drivers-installed-on-ubuntu-18-04-ma) – ComputerScientist Sep 26 '20 at 21:59
@ComputerScientist I am not certain that it is still necessary. Please start a new question and we'll investigate. – chili555 Sep 27 '20 at 00:07
