 Posted: Tue Jul 19, 2022 1:39 pm Post subject: [Solved] WIFI disconnects every 15 seconds |
 |
|
Hi, guys.
Need help with wifi TL-WN722N USB dongle.
This device works fine on old machine with (reletively) old kernel-5.15.26. As well it works fine under Windows10.
But I can't use it on new machine with kernel-5.18.2.
Under 5.18.2 device works only for 15 secs or so. It disconnects after 15 seconds and stays disconnected for about next 15 seconds. And then it rescans available networks, finds my SSID and connects to it. And works for another 15 seconds. And so on, endless loop. Ping to 8.8.8.8 is slow - from 200ms up to 600 ms, packet loss is about 50%, download speed is low 20Mbits (50 MBits on old machine)
This is the portion of wpa_supplicant output which appears on every reconnection:
| Code: | RTM_NEWLINK: operstate=1 ifi_flags=0x11043 ([UP][RUNNING][LOWER_UP])

I tried to build 5.18.2 kernel upon the old 5.15.26 .config (using make oldconfig), to make sure I didn't miss any wifi-related option when configured 5.18.2 kernel, but it doesn't help.
I cannot downgrade kernel to 5.15.26 due to my video.
Any ideas on how to fix this problem?

I'm guessing you have conflicting network management. Network Manager and something else.
What is the output of /sbin/rc-update?

I have no network manager installed, and never had before.
rc-update
Before starting wlan0 I stopping eth0 to prevent any collision. On exit (Ctrl+C) wlan0 going down and eth0 starts again.
| Code: | #!/bin/bash
/etc/init.d/net.eth0 stop
ifconfig -v wlan0 up
ifconfig wlan0 192.168.1.77
ip route add default via 192.168.1.1 dev wlan0
wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant-109.conf -dd
ifconfig -v wlan0 down
/etc/init.d/net.eth0 start |
Some additional info: I tried to install 5.18.2 kernel on old machine, which works fine with my wifi under 5.15.26 kernel and got the same behaviour - disconnection every 15 seconds.
So it's seems for me as a kernel issue.

5.18.2 is quite old also (we are at 5.18.12 at the moment) ... If you need a recent kernel because of your video, I would like to know if the problem is existent under 5.15.52 (gentoo stable), or 5.15.55 (newest version of 5.15-series at the moment) also ? If you have the same problem with a newer 5.15-kernel I dont think its a kernel problem. Maybe you should try 5.18.12 also ... |

Have you compared what is different between the two kernel configurations?

Yes, I did, they are identical.
@pietinger
I just installed the last available 5.15 branch sources - 5.15.52 kernel, and built it upon 5.18.2 config. Just copied .config from 5.18.2 and put it into 5.15.52 directory and ran make oldconfig. Rebooted and wifi works, no interrupts. OK, average ping is 120 ms, not a 50 ms, but it works and doesn't disconnect every 15 seconds.
Software is the same, hardware is the same, the only difference is kernel. Even kernel config is the same.
As for me it seems like a kernel issue.

Good information. So, 5.15 looks like clean. Now I would like to ask what is with 5.18.12 ? Maybe there have been some patches between 5.18.2 and 5.18.12 which solve the problem ...
(pls do the same update as you did: copying .config and starting "make oldconfig" (NOT "make olddefconfig"))
If 5.18.12 have the same problem I would say it is a kernel problem; if not I would say it was a problem with version .2 |

I have no 5.18.12 sources. Only 5.18.8 and 5.18.10.
5.18.8 I already tried - doesn't work.
Will try 5.18.10.

OK, tried 5.18.10 - doesn't work.
What I found: old branch 5.15.* has an option 88EU_AP_MODE, tho it isn't set:
| Code: | # cat .config |grep 88EU_AP_MODE
# CONFIG_88EU_AP_MODE is not set |
this option related to my wifi module - r8188eu
new branche kernels 5.18.* lacks of 88EU_AP_MODE symbol at all. And since it disabled at 5.15.* I think it doesn't a problem

Blind_Sniper,
Look in you dmesg for the disconnects.
What is the reason code?

@NeddySeagoon,
no any changes in dmesg. Neither on disconnection, nor on reconnection. Nothing.

Two months later...
Tried latest available 5.19.9 kernel. Still wifi doesn't work.
Should I file a bug?

Blind_Sniper,
Its probably not a bug. If it were, it would already be filed and maybe fixed.
You would be unlikely to be first. A little like the Fermi paradox.
Pastebin the output of with your normal collection of USB devices connected.
That will allow us to check for USB root hub over current conditions. It will provide the Vendor and Device IDs so we can check your kernel too.
Pastebin youer kernel .config file.
Pastebin dmesg, after the interface has cycled a few times.
Read the comments in /etc/rc.conf above | Code: | | #rc_depend_strict="YES" |
Then uncomment it and set it to "NO"
Configure the /etc/conf.d/net file to be able to start wifi and add the symlink to /etc/init.d/. There is no need to add it to any runlevel.
Now OpenRC knows about wifi and will be happy to keep network dependent services up if either interface is up.

It's a lsusb -vvv output: https://pastebin.com/8r03FzdY
And kernel config: https://pastebin.com/2MpFmDtL
As you suggested, I uncommented
| Code: | | rc_depend_strict="NO" |
Added wlan configuration to /etc/conf.d/net:
| Code: | config_eth0="192.168.1.5 netmask 255.255.255.0 brd 192.168.1.255"
routes_eth0="default via 192.168.1.1"
config_wlan0="192.168.1.77 netmask 255.255.255.0 brd 192.168.1.255"
routes_wlan0="default via 192.168.1.1"
modules="wpa_supplicant"
wpa_supplicant_wlan0="-Dwext" |
Created /etc/init.d/net.wlan0 link to net.lo and rebooted. After reboot I stopped eth0 to prevent any possible interferes from eth0 and started /etc/init.d/net.wlan0
| Code: | # /etc/init.d/net.wlan0 start
* Bringing up interface wlan0
* Caching network module dependencies
* Starting wpa_supplicant on wlan0 ...
Successfully initialized wpa_supplicant
rfkill: Cannot get wiphy information

ioctl[SIOCSIWENCODEEXT]: Invalid argument [ ok ]
* Starting wpa_cli on wlan0 ... [ ok ]
* Backgrounding ... ...
* WARNING: net.wlan0 has started, but is inactive |
Still the same behavior: Internet works 15 seconds, then stops working for next 15 seconds and appears for next 15 seconds again. And so on.
When internet disappears wlan0 doesn't stop, it still up, just no internet. And no any changes in dmesg.
It's the few last lines of dmesg:

I still think it's a kernel issue. When booted into the same system with old kernel, wifi works fine.

Found alternative driver (8188eu.ko) here: https://github.com/lwfinger/rtl8188eu
Works good, no any interrupts for a last 30 minutes.
Will see how long it will work

Maybe you should wait a little bit with 5.18 and 5.19-rc
