Ubuntu Wifi sigue reconectándose incluso después de reconfigurar el enrutador

Tengo instalado ubuntu 20.04 y, para una conexión Wifi específica (la que tengo en mi casa), tengo el siguiente problema: el wifi se desconecta y se vuelve a conectar después de un tiempo (probablemente cada 3 o 5 minutos).

Aquí esta lo que hice:

  1. Cambié la configuración de la ruta para que sea la siguiente:

Esto no sucede en ninguna otra conexión wifi y mis dispositivos Windows y Android funcionan perfectamente en la misma red Wifi. ¿Hay alguna configuración que deba hacer para que mi Ubuntu funcione en mi wifi?

Respuesta1

Según el resultado tail -f /var/log/syslogy el cambio de la configuración del enrutador, supuse que la configuración de WiFi no se ha cambiado correctamente en Network Manager. La solución a este problema es sencilla simplemente:

  1. apertura nm-connection-editoren la terminal
  2. Seleccionar y eliminar la conexión WiFi
  3. Conéctate al mismo WiFi desde el principio

Respuesta2

kanzzmm2la respuesta es correcta.

Agregaría solo un paso: reiniciar NetworkManager. Sólo después de este paso mi red vuelve a la estabilidad.

Estoy usando 20.04.5 LTS con una configuración MESH.
