Re: Wi-Fi network connection keeps disconecting every 5~9 seconds [SOLVED]

There's

wrz 28 16:33:21 archlinux kernel: wlan0: deauthenticated from a6:83:93:ac:34:eb (Reason: 7=CLASS3_FRAME_FROM_NONASSOC_STA)
wrz 28 16:37:18 archlinux kernel: wlan0: deauthenticated from a6:83:93:ac:34:eb (Reason: 7=CLASS3_FRAME_FROM_NONASSOC_STA)

but nothing suggests a problem at a 5s-9s frequency.

ping to google keep running … i download something from steam … download is going low (but no 0, this is propably "softening")  and going up again

get only 3 communication like this:

Looks like a repeater.

So first, we need to figure what the problem actually is.
1. get steam out of the equation, does the linode speedtest stall when you're downloading the 1GB testfile?
2. do you have access to another AP (not a phone hotspot)?

I connect to the same wi-fi with different computers (and system Windows, when i have installed on my computer) and they dont have the same issue as I have.

3. so do you have access to another host that you can use as peer in the same LAN (even if both are connected to the phone hotspot) for a LAN iperf test?

Answer:

no, it can go like download speed to 12kb/s  on my phone, but its still downloading but i can crearly see that download speed is going down in this moment on the console of $ ./abbs net speed.

Answer:

Not now. But maybe i could go to my friend and test something.

Answer:

I will try, i have windows on different computer but there is iperf on windows. When i try/finish this task, i will edit this post.

EDIT:

Every time console show nothing. When i use ctrl + c on widows then something is showing up.

Something is not rigth.

$ iperf -s

NOTHING HAPPEND, WHEN I CTRL+C ON WINDOWS:

i used ctrl +c couple times on windows but last result is for me scary.
When i try connect first time i have error. (and maybe second time, i dont remember).

Re: Wi-Fi network connection keeps disconecting every 5~9 seconds [SOLVED]

I've no experience w/ iperf on windows, idk what it would or not print and I assume ctrl+c doesn't work in regular cmd.exe (might in powershell?) but it also looks likey you're running iperf2 (on linux) against iperf3.exe (on windows) - which won't work. iperf3 isn't compatible w/ iperf2

Re: Wi-Fi network connection keeps disconecting every 5~9 seconds [SOLVED]

So it's not steam, the throughput collapses every 15s or so.
Assuming it's not power saving because you've disabled all of that:
Can you connect the phone on 5GHz? Do you use any bluetooth devices on the system?

I can, but problem is the same.

With 5Ghz router (smartphone) and sudo iw dev wlan0 set power_save off

[janusz@archlinux ~]$ sudo iw dev wlan0 set power_save off

Re: Wi-Fi network connection keeps disconecting every 5~9 seconds [SOLVED]

Is it the same phone or a different one?
(Also notice that RX and TX have swapped performance here)

Do you use any bluetooth devices on the system?

In doubt, try to rfkill the bluetooth device (though it won't interfere on 5GHz…)

Last thing: don't use NM, try to connect w/ wifi-manager from netctl (or wpa_supplicant manually)
NMs scanning and MAC juggling habits might get into the way here - somehow…

Re: Wi-Fi network connection keeps disconecting every 5~9 seconds [SOLVED]

Change to netctl from NetworkManager.
Change dns conf to google servers. (NetworkManager create somethong that's doesnt work)

iperf Done.
[janusz@archlinux ~]$

First try without sudo iw dev wlan0 set power_save off.

The same.

Second try with sudo iw dev wlan0 set power_save off.

I almost get it. In the end something terrible happend. But maybe now i need some limits? Maybe its overloaded or heat now? Change some parameters?

Edit:

Maybe good idea is to come back to windows, get proporties of driver and do this in arch? It can be done? Or im crazy man.

Edit2:

I never turn on bluetooth on this computer. I never use it. On my phone too.

I will install windows, get transmit bitrates of wlan0, go back to arch, and modify by:

iw wlan0 set bitrates legacy-2.4 12 18 24
iw wlan0 set bitrates legacy-2.4 6 12 24
iw dev wlan0 set bitrates mcs-5 4
iw dev wlan0 set bitrates mcs-2.4 10

No idea what your though process is, but that will generally not work.
You could instead test the behavior
1. with some live distro (eg. grml or so)
2. against a different router/AP.

What exactly do you mean by that?

When i was trying to install linux first time, i choose Debian. When i try to install debian with live image, i was having 2 issues: no working keyboard and no wifi. Later I read that keyboard works in newer versions of kernel. Then I install arch. And wifi also starts working. Propably because of newer kernel.

Later I will go to friend and test here connection.

Meanwhile i install windows and evrything sems to be working good: https://pastebin.com/km7vUxas

Now i will install arch again.

Re: Wi-Fi network connection keeps disconecting every 5~9 seconds [SOLVED]

What is the output of

sudo dmesg | grep wlan

also try adding:

network={
        ssid="yourSSID"
        psk="yourpassword"
        mode=0
        key_mgmt=WPA-PSK
        ieee80211n=1
        disable_ht40=1
}

in /etc/wpa_supplicant/wpa_supplicant.conf and restart wpa_supplicant
and see if it fixes your problem :)

Re: Wi-Fi network connection keeps disconecting every 5~9 seconds [SOLVED]

http://0x0.st/XgNm.txt
https://linux-hardware.org/?id=pci:10ec-b852-17aa-4853

The critical values would be

        ieee80211n=1
        disable_ht40=1

@janusz-bit, to try this you'll have to stop networkmanager and connect w/ wpa_supplicant manually, https://wiki.archlinux.org/title/Wpa_supplicant#Manual

Re: Wi-Fi network connection keeps disconecting every 5~9 seconds [SOLVED]

Thanks, it worked.

When i reinstall my arch linux I install netctl and my internet was working better but still was unstable.

Then I edit profiles in "/etc/netctl/" and I added "WPAOptions='ieee80211n=1 disable_ht40=1'".
It works. I test my connection using iperf3 and connection is stable. Downloading something from internet now works smoothly.

Thank you for your help @spicemonke and @seth.
