WiFi inestable después de la actualización 17.10

17

Mi conexión wifi es muy inestable después de la actualización 17.10 (desde 17.04). Estoy experimentando desconexiones frecuentes (cada 10 ~ 15 minutos), una simple reconexión al SSID resuelve el problema.

El modelo de tarjeta es:

sudo lshw -class network

########## wireless info END ############

Edit: The solution provided by Zsolt Rizsányi works, alternatively I choose to change my WiFi card by an Intel 8265 which have a better range and a better support of the 5G frequency.

@DavidFoerster Thanks for pointing this out, I've edited the question with the result.

The system log indicates that the wireless connection was dissociated from the access point deliberately. I don't have a specific recommendation aside from various driver module options suggested in answers to other questions about the unstable connections with the same WiFi module. See askubuntu.com/….
David Foerster
Yes like I said I have to disconnect / reconnect every 10 minutes.

Have the same issue on an Asus UX303LA laptop. It's a clean install but ran 17.04 as well previously without any problems.

I had the same issue and found a Debian bug report that also has a solution. See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=879184

The solution is simple: install updated firmware from firmware repository provided by Qualcomm.

Detailed steps:

  1. Download https://github.com/kvalo/ath10k-firmware/blob/master/QCA6174/hw3.0/board-2.bin and overwrite /lib/firmware/ath10k/QCA6174/hw3.0/board-2.bin with the downloaded file.

  2. Download https://github.com/kvalo/ath10k-firmware/blob/master/QCA6174/hw3.0/4.4.1/firmware-6.bin_WLAN.RM.4.4.1-00065-QCARMSWP-1 and overwrite /lib/firmware/ath10k/QCA6174/hw3.0/firmware-6.bin.

  3. Restart

This solution worked for me. The only problem is the UI can show "?" for the connection for a few minutes even if the connection is working fine.
Fritzy
For point 2., which is the final name of that file: firmware-6.bin_WLAN.RM.4.4.1-00065-QCARMSWP-1 or firmware-6.bin?
ROMANIA_engineer
firmware-6.bin (there is already a file with that name, you need to overwrite it)

This also happens now that Ubuntu 16.04 has the 4.13 kernel and linux-firmware 1.157.14.

Guys, those of you who are affected, please report that you're also affected here: bugs.launchpad.net/bugs/1743279

This bug has been reported on launchpad: https://bugs.launchpad.net/bugs/1743279 If you're affected, please tell them in the bug report so they can fix the bug ASAP.

The firmware-6.bin file needs to be updated. Ubuntu currently ships version WLAN.RM.4.4-00022-QCARMSWPZ-2 and the fix for this issue was released in version WLAN.RM.4.4.1-00051-QCARMSWP-1, which means you need some version later than the latter for the card to work properly on >4.12 kernels.

As of today, this bug can be fixed by simply replacing the board-2.bin (not actually required but recommended) and firmware-6.bin files with what's currently in the upstream repository for linux-firmware, or by grabbing the firmware-6.bin from kvalo's repository for the proper version.

You can grab the correct version from kvalo's repository, which is guaranteed to always work (if you don't require the new board-2.bin as well).

These commands below will automate the replacement of the files:

$ sudo wget https://github.com/kvalo/ath10k-firmware/raw/master/QCA6174/hw3.0/4.4.1/firmware-6.bin_WLAN.RM.4.4.1-00051-QCARMSWP-1 -O /lib/firmware/ath10k/QCA6174/hw3.0/firmware-6.bin

Alternatively, you can grab the files from the current state of linux-firmware These commands below will automate the replacement of the files from what's upstream (notice these commands might work now but there's no guarantee they will work in the future because the repository's contents can change, although they will hardly ever break things like this).

$ sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/ath10k/QCA6174/hw3.0/board-2.bin -O /lib/firmware/ath10k/QCA6174/hw3.0/board-2.bin
$ sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/ath10k/QCA6174/hw3.0/firmware-6.bin -O /lib/firmware/ath10k/QCA6174/hw3.0/firmware-6.bin

Then reboot.

I have this card in my laptop but don't use it. Still +1 for your research improving the overall environment in case I use it some day.

@WinEunuuchs2Unix thanks. If you happen to be affected by it someday please report it in the bug report I've linked here.

I subscribed to the bug report and recorded as being affected as I have noticed WiFi reconnecting from time to time on Kernel 4.14. But as I mentioned I'm teethered to the good old blue wire.

Veo que la corrección de errores se ha introducido en las propuestas 16.04 y 17.10 . ¿Es hora de actualizar esta respuesta?

Sí lo hará Tenga en cuenta que este error se corrigió en la versión 1.157.16 o el paquete en Xenial y 1.169.3 en Artful.

EDITAR: La solución correcta para esto es instalar los controladores manualmente y no cambiar su configuración wifi en su red. Al menos hasta que se incluyan controladores más nuevos en ubuntu.

Un cambio en mis enrutadores wifi solucionó esto, no estoy seguro de si los AP o el kernel / controladores de Linux tienen la culpa aquí.

On OpenWrt/LEDA, option wpa_group_rekey '0'

Needs to be added to the wireless "wifi-iface" configs. There is no option within the web config interface.

ACTUALIZACIÓN: configuré esto en 3600 y el mismo problema ocurrió nuevamente, supongo que no se está negociando entre el cliente y WAP. Todavía es probablemente un error de Linux / controlador. Establecí esto en 3600 en lugar de 0, ya que es teóricamente más seguro pero no funciona, supongo que cero significa que no regenera una clave.

Este es un error conocido que se ha corregido en sentido ascendente, pero también abrí un informe de error en el Launchpad: bugs.launchpad.net/bugs/1743279 , contribuya allí informando que también está afectado.

Estaba con el mismo problema. Aquí cómo resuelvo el problema: https://ubuntuforums.org/showthread.php?t=2261225

Vaya a la configuración de seguridad de su módem wifi.

Si el período de actualización de clave de grupo WPA / WPA2 es cero o está deshabilitado, debe cambiarlo.

Establezca el período de actualización de clave de grupo WPA / WPA2 en 86400 como se muestra en la captura de pantalla.

Guarde su configuración y reinicie su módem / enrutador.

De hecho, pero prefiero que el controlador maneje la actualización de la clave de grupo correctamente.

No es posible cambiar esta configuración en los aeropuertos de apple express :(
