Hey everyone,

I’m having some issues with my Wi-Fi connection. When there’s a load from another process, my Steam connection (Steam chat) gets disconnected frequently. I’ve read some articles online, and I believe there’s a setting to address this; however, I couldn’t find it in Fedora 40. I’ve already disabled Wi-Fi power saving by adding the following to /etc/NetworkManager/conf.d/wifi-powersave-off.conf

[connection]
wifi.powersave = 2

My card is

49:00.0 Network controller: Intel Corporation Wi-Fi 6E(802.11ax) AX210/AX1675* 2x2 [Typhoon Peak] (rev 1a)

But that didn’t work.

Thanks!

I don’t know how to disable Intel Killer wifi bandwith control, but in order to confirm that such NetworkManager configuration works, use this command

iw dev wlp0s20f3 get power_save

(Where wlp0s20f3 is the device name).

It says

Power save: off

Also I’ve realized my qdisc strategy is noqueue

$ tc -s qdisc show dev wlp73s0
qdisc noqueue 0: root refcnt 2 
 Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) 
 backlog 0b 0p requeues 0

I saw some people suggests that to set it pfifo_fast

However, I don’t know how I can set it. Actually I don’t know which one is better.
