I am new to Ubuntu and after I installed Ubuntu on my PC, I am experiencing a terribly slow WiFi connection (but faster on Windows). I tried to disable the 802.11n and the Intel driver card but it gives me the following error (running sudo modprobe -r iwlwifi):

rmmod: ERROR: missing module name.
modprobe: FATAL: Error running remove command for iwlwifi

I also tried following this answer but lspci -nn | grep 0280 returns nothing on my Terminal.

When running lspci -knn | grep -i net it returns:

00:19.0 Ethernet controller [0200]: Intel Corporation 82567LM-3 
Gigabit Network Connection [8086:10de] (rev 02)
Subsystem: Dell 82567LM-3 Gigabit Network Connection [1028:027f]

Any help would be appreciated. Thank you so much!

  • lspci -knn | grep -i net command don't shown wireless interface, try to find your hardware type by other way. – PRIHLOP Jan 10 '19 at 21:18

  • Try the next command lspci -knn | grep -i Wireless And try also command without grep, only lspci -knn and find someting with words network and wireless – PRIHLOP Jan 10 '19 at 21:30

For those coming across this still, check your kernel version with uname -a. If the version is 5.1 or greater, it should support your hardware without needing the iwlwifi driver.

Remove the iwlwifi driver (cautiously if you don't have an ethernet backup):

  1. apt search ilwwifi. You should see something like:
Sorting... Done
Full Text Search... Done
backport-iwlwifi-dkms/focal,focal 8324-0ubuntu1 all iwlwifi driver backport in DKMS format

oem-wifi-iwlwifi-mainline-5.1rc1-dkms/now 6 amd64 [residual-config] (none)
  1. Remove each that is installed on your machine. For example apt remove backport-iwlwifi-dkms oem-wifi-iwlwifi-mainline-5.1rc1-dkms
  2. Reboot if needed.
