Intel WiFi - Unbearably slow and unstable internet connection

Issues & Assistance Networking Support

Hello,

I’ve used garuda linux dr460nized for a couple months now and i’ve always had problems staying connected to the internet, when it is connected it tends to be extremely slow and laggy. I’ve tried every fix i saw here as well as on the arch linux forum, with nothing seeming to work despite speed tests usually returning with 50-60MBPS, and never seeing this problem before i switched to garuda linux.

Here’s my inxi:

Fix it.

LAN or WLAN?
Please post comand and output from terminal.

ip a

Seems WLAN Problem :slight_smile:

Hi there @jackassington.

I have never seen such a messed up network inxi output with so many different components listed. Please clarify exactly which WiFi adapter you wish to get working. Remove all other network devices other than that one specific device you wish to use from your system.

You have 3 different WiFi devices listed in your inxi output. Two of the devices listed are intel:

Device-1: Intel Wi-Fi 6 AX200 driver: iwlwifi v: kernel modules: wl

Device-2: Intel Wi-Fi 5 Wireless-AC 9x6x [Thunder Peak] driver: iwlwifi
v: kernel modules: wl

Another USB WiFi device is listed in your inxi is a railink/Mediatek WiFi adapter:

Device-4: NetGear A6210 driver: mt76x2u type: USB rev: 2.1 speed: 480 Mb/s

We need to know exactly which device is the only WiFi adapter you intend to use.

Your system has been installed for a while now, and unfortunately we have no way of knowing exactly what changes you’ve made since you first installed. The only way for us to know how your system performs without any modifications is from a live environment.

Please boot from your Garuda install disk with only one WiFi device connected to your computer.

Does your WiFi work properly in the live environment?

From the live boot environment run the following commands and post the output given while using the live boot disk:

inxi -n

lsmod | sort

Save the command input and output to a file, then post the results of those commands on the forum.

On your system installed to metal:

Be sure you only have one WiFi device attached, then remove any other WiFi drivers you’ve explicitly installed.

The WL driver is showing up in your inxi output and it definitely should not be loaded. You have a lengthy list of network components, but none of them are Broadcom WiFi adapters. Uninstall any WL driver package that is intended for broadcom WiFi adapters from your Garuda installation.

Also uninstall any Mediatek WiFi drivers, if you have any installed on your system.

I also see that you have disabled IPv6 in your kernel parameters. Please reenable IPv6.

Until we get some clarification it will be very difficult to know what is happening with your system.

Please answer any questions I’ve asked, and post the command input/outputs obtained from the live environment.

I will attempt to help you, but without the information I’ve requested it will be an uphill battle.

First off, i’m using the Intel Wi-Fi 5 Wireless-AC 9x6x, and i have removed the others like you suggested.

It definitely works better in the live environment so i would say it does. Here are the command outputs:

I have also uninstalled the WL driver package, and i don’t think i’ve installed any mediatek drivers but i could be wrong. IPv6 is reenabled as well.

A few suggestions:

A recurrent bug with Intel WiFi adapters sometimes results in very slow speeds. This can on some models be corrected by using ethtool to disable TSO.

Before we go much further you should delete any iwlwifi driver options file in /etc/modprobe.d so we know that all options are set to the default.

Have you tried alternate kernels, if so which ones? Be sure to test at least the linux-lts and linux-mainline kernels.

You should also test older versions of the Intel iwlwifi firmware, see:

Important Note

In the commands below your adapter designation will likely need to be altered. The current adapter designation in the below commands is wlp2s0. Run inxi -n to find your adapter’s current designation. It may be wlp3s0 or wlp4s0 or possibly another alphanumeric combination starting with wlp. Be sure to substitute wlp3s0 (or whatever else your adapter is identified as), in place of wlp2s0 in any of the commands below.

There are numerous iwlwifi driver options that often help improve performance with Intel wifi adapters.You can test alternate iwlwifi driver options on the fly via rmmodding & modprobing the iwlwifi driver.

If your Intel wifi connectivity is impaired, you can test alternate iwlwifi driver options by selectively running each of the following commands:

Execute the first command below, and then test if your connection is restored and remains stable afterwards.

bash -c "nmcli networking off; sudo systemctl stop NetworkManager; sudo ip link set wlp2s0 down; sleep 1; sudo lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs sudo rmmod; sleep 3; sudo modprobe iwlwifi 11n_disable=1; sleep 1; sudo ip link set wlp2s0 up; sleep 1; sudo systemctl start NetworkManager; nmcli networking on; sleep 1; nmcli r wifi off; sleep 1; nmcli r wifi on"

If executing the first command didn’t help, then run the second command below. Test if your connection is restored and remains stable after running the next command.

bash -c "nmcli networking off; sudo systemctl stop NetworkManager; sudo ip link set wlp2s0 down; sleep 1; sudo lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs sudo rmmod; sleep 3; sudo modprobe iwlwifi 11n_disable=8; sleep 1; sudo ip link set wlp2s0 up; sleep 1; sudo systemctl start NetworkManager; nmcli networking on; sleep 1; nmcli r wifi off; sleep 1; nmcli r wifi on"

If executing the second command didn’t help, then run the following command below. Test if your connection is restored and remains stable after running the final command below.

bash -c "nmcli networking off; sudo systemctl stop NetworkManager; sudo ip link set wlp2s0 down; sleep 1; sudo lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs sudo rmmod; sleep 3; sudo modprobe iwlwifi 11n_disable=8 bt_coex_active=0; sleep 1; sudo ip link set wlp2s0 up; sleep 1; sudo systemctl start NetworkManager; nmcli networking on; sleep 1; nmcli r wifi off; sleep 1; nmcli r wifi on"

The iwlwifi driver option modifications implemented with the above commands will only remain in effect during the current session. Rebooting will nullify changes that executing any of the above commands instituted. If the driver options I suggested above improve your wifi’s performance, then an ilwifi driver configuration file will need to be createdd in /etc/modprobe.d for the changes to be made persistent.

If any of the temporary modprobe commands you tested earlier correct your connectivity issue, then follow the instructions below to create a lasting fix.

The following commands below will auto-generate the required /etc/modprobe.d/iwlwifi.conf Intel wifi driver configuation file.

If during testing the first command improved your connectivity, then execute the following in the terminal:

echo "options iwlwifi 11n_disable=1 " | sudo tee /etc/modprobe.d/iwlwifi.conf

If during testing the second command improved your connectivity, then execute the following in the terminal:

echo "options iwlwifi 11n_disable=8 " | sudo tee /etc/modprobe.d/iwlwifi.conf

If during testing the third command improved your connectivity, then execute the following in the terminal:

echo "options iwlwifi 11n_disable=8 bt_coex_active=0 " | sudo tee /etc/modprobe.d/iwlwifi.conf

You can also try further modifying your Intel wifi’s power saving options by adding extra parameters to the /etc/modprobe.d/iwlwifi.conf file.

Run the following command(s) to add experimental power saving options to the Intel wifi configuration file that sometimes improve reliability:

echo -e "options iwlwifi power_save=0\noptions iwlmvm power_scheme=1" | sudo tee -a /etc/modprobe.d/iwlwifi.conf

If the above command does not improve your wifi performance significantly, then run the following command to again ammend /etc/modprobe.d/iwlwificonf to add further power saving options:

echo 'options iwlwifi power_save=0 d0i3_disable=0 uapsd_disable=0' | sudo tee -a /etc/modprobe.d/iwlwifi.conf

Reboot after creatiing or making any changes to the /etc/modprobe.d/iwlwifi.conf Intel wifi configuration file, then test for improvements.

Glad to see those suggestions helped.

Could you please clarify for other Intel wifi users exactly which suggestion(s) helped.

This first command worked perfectly along with disabling TCP, thank you!!
