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:

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.
