Network Instability in Marvel Rivals

Hello I am experiencing Network instability where my ping regularly jumps from 30-50ms to 100ms+. I have ran the Network Diagnostics in the game and got all connection error from my device -->Router-->ISP Gateway--> Game Server

On Window the game run completely normal with no ping spike

I have tried  modifying the iwlwifi.conf
options iwlwifi power_save=0
options iwlwifi bt_coex_active=0
options iwlwifi swcrypto=1

update my linux-firmware

I also tried different Proton including and GE Proton latest version.
My launch option is: gamemoderun %command%  -PS0CompileMode=1

Re: Network Instability in Marvel Rivals

Hi! Is it possible that you can plug an ethernet cable into your device? This would be a good first test, as it will determine if the issues are stemming from your hardware, or your software. I've personally never experienced this on Marvel Rivals, and I couldn't find any other examples of this happening on the internet, so this is really interesting!

Let me know if you can or can't do this. Totally fine ether way. (see what i did there? i'll see myself out.)

I don't use ethernet cable but I don't see how this would work since on Windows the game work completely fine even without ethernet cable.
Thank you for the reply tho!

I am sorry but you might be right about using an ethernet cable. I will check this out and also i see your pun lol.

Yes, I'm not suggesting using the ethernet cable as a permanent fix - just as a troubleshooting step to get us going in the right direction faster.

Re: Network Instability in Marvel Rivals

Awesome - so now we know the issue is somewhere in the WiFi drivers for Linux. Let’s get some basic information first.

First of all, I would like to see the output from

$ lspci -k

This will confirm that you’re using the correct firmware for you WiFi device.

Next, what WiFi manager are you using? NetworkManager? iwd? Something else?
A common WiFi error is having multiple WiFi managers running at the same time, so I just want to make sure this isn’t the case with you.

Is the ping more often 100+ or normal on WiFi?

Also, do you notice that when you are using the computer, your WiFi “randomly” disconnects for a few seconds?

Let me know,
J

Yes I use NetworkManager , iwctl . The ping is spike up to 100+ yes when I use the computer my Wifi doesn't randomly disconnects

Re: Network Instability in Marvel Rivals

Alright - a few things wrong here. First of all, this line

libkmod: ERROR: kmod_config_parse: /etc/modprobe.d/iwlwifi.conf line 2: ignoring bad line starting with 'option'
00:01.0 PCI bridge: Intel Corporation 12th Gen Core Processor PCI Express x16 Controller #1 (rev 02)

tells us that your iwlwifi.conf file is syntactically incorrect. First, let's backup the file by changing the extension so it is no longer included.

# mv /etc/modprobe.d/iwlwifi.conf /etc/modprobe.d/iwlwifi.conf.bak 

Our next issue is that you are using iwd with NetworkManager. This is a problem if you aren't specific in your configuration. NetworkManager's default supplicant is wpa_supplicant. However, when you have iwd enabled & running (like you suggest by saying that you use iwctl), iwd and wpa_supplicant are "fighting" over the control of the wifi. This can cause latency, sudden disconnections, and more.

There are a few ways to fix this:

1. Remove NetworkManager and use iwd and iwctl to manage your wireless networks.
2. Remove iwd and use NetworkManager with wpa_supplicant to manage your wireless networks.
3. (what I use) Keep both installed, use NetworkManager as a frontend and iwd as a supplicant, because iwd is newer and has better integrations with the kernel.

To do number three, add

[device]
wifi.backend = iwd

to

 /etc/NetworkManager/NetworkManager.conf 

then stop NetworkManager with

# systemctl stop NetworkManager 

stop & disable wpa_supplicant with

# systemctl disable --now wpa_supplicant 

stop & disable iwd with

# systemctl disable --now iwd 

and start and enable NetworkManager with

# systemctl enable --now NetworkManager 

To decide which one you want, read the Arch Wiki! It's super great. Some helpful articles:
https://wiki.archlinux.org/title/NetworkManager
https://wiki.archlinux.org/title/Networ … Fi_backend
https://wiki.archlinux.org/title/Iwd
https://wiki.archlinux.org/title/Network_configuration

After doing all of this and deciding on the correct network management option, reboot your computer and let me know how everything works!

Good luck,
J

Please use [ code ] [ /code ] tags for program output , see https://bbs.archlinux.org/help.php#bbcode

A common WiFi error is having multiple WiFi managers running at the same time, so I just want to make sure this isn’t the case with you.

That is a very common network configuration error.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky
