Tengo una nueva tablet Thomson Teo 13.3 Android 11 (empecé desde los valores predeterminados de fábrica, es nuevo ). He creado una nueva red Wi-Fi en mi router NETGEAR WAX202, llamémosla SSID "MiRed2", y he hecho que esta tablet se conecte a ella. Da vueltas en "obtener dirección IP" por un tiempo; y luego dice "Guardado" y eso es todo lo que muestra.

Tengo 5 dispositivos en mi red doméstica conectados al mismo router y funcionan sin problemas, aunque están conectados a una red Wi-Fi diferente. Para probar, hice que mi smartphone Samsung con LineageOS 17 se conectara a esta "MiRed2" - sin problema alguno. Así que no es el router, me imagino.

He encontrado que Android 11 introdujo algunos cambios que pueden romper la conectividad de red WiFi. Algunos de los artículos que leí:

Conexión de dispositivos Android 11+ a SSID WPA/WPA2/WPA3/Enterprise

Desde la mejora de seguridad de Android 11 lanzada en diciembre de 2020, esto ha cambiado y, como resultado, no se puede omitir la validación del certificado.

PSA: Android 11 ya no te dejará conectarte de forma insegura a redes WiFi empresariales

El problema con el que se encontrarán muchos usuarios tras actualizar a Android 11* es que se ha eliminado la opción "No validar" del desplegable "Certificado CA"

Aunque probablemente eso no se aplique a mí, porque no utilizo una red de empresa.

Con el tiempo también encontré:

Problemas de conexión Wi-Fi con el Xiaomi Mi A2

había activado WPA junto con WPA2 en el AP. También confirmaron que no era algo que pudiera haber hecho yo mismo, ya que no hay ninguna opción relevante en la parte "de cara al usuario" del panel de configuración. ...

... lo que a su vez lleva a wpa_supplicant a ignorar el hecho de que hay una etiqueta MBO/OCE (que está, por supuesto, todavía presente) a pesar de que el AP no soporta PMF como se informa en el RSN IE, y sólo utiliza el WPA IE para elegir los cifrados necesarios

No entiendo ni la mitad de lo que se dice aquí, pero he probado a desactivar las frecuencias duales en la red WiFi, y a añadir tanto WPA como WPA2 - y por supuesto, esto tampoco ha funcionado.

De todos modos, he intentado obtener un logcat durante los intentos de conexión, cuando la red WiFi está en este estado:

Intenté buscar sólo lo relevante:

No consigo entender los registros anteriores. No son más que un galimatías para un usuario final que intenta depurar su problema.

Así que, ¿alguien tiene una idea acerca de lo que está mal aquí - y lo que debo hacer para conseguir la conexión WiFi con esta tablet en este router y el trabajo de red?

En primer lugar, encontré https://f-droid.org/packages/com.vrem.wifianalyzer/ - obviamente, tuvo que instalarse a través de adb install a través de USB, ya que no tenía WiFi.

Pero este programa mostró, que todo lo que este dispositivo puede ver, son redes en el rango de 2,4 GHz. Así que configuré mi red sólo en 5 GHz, y de repente era invisible para la tablet.

Entonces pensé que debía mirar más de cerca las especificaciones de la tablet. Por supuesto, no hay especificaciones de la tablet para encontrar fácilmente.

Afortunadamente, por fin he encontrado algo que parece más o menos razonable:

https://mobilespecs.net/tablet/THOMSON/Thomson_TEO_13P_T13P2BK32V2_32_GB_13.3_T13P2BK32V3.html

Modelo de procesador: A133

Familia de procesadores: Allwinner

Estándares Wi-Fi: 802.11b, 802.11g, Wi-Fi 4 (802.11n)

El mejor estándar Wi-Fi: Wi-Fi 4 (802.11n)

Por desgracia (aunque era de esperar), no se menciona qué chipset WiFi se utiliza; he encontrado esto: https://www.cnx-software.com/2020/10/31/allwinner-a133-tablet-processor-pairs-with-xr829-or-aw859a-wifi-bluetooth-chip/

la empresa también combina el procesador A133 con sus propios chips inalámbricos, ya sea el chip XR829 WiFI 4 y Bluetooth 4.2, o el chip AW859A WiFi 5 802.11ac de doble banda y Bluetooth 5.

Así que creo que este dispositivo tiene un chipset WiFi XR829. Pero no importa eso.

Si miro https://www.rfwireless-world.com/Terminology/difference-between-wifi-6-and-wifi-5.html - mencionan que WiFi 3 "admite bandas de frecuencia de 2,4 GHz y 5 GHz", pero no hay ninguna mención de este tipo para WiFi 4. Por lo tanto, no puedo decir realmente, si WiFi 4 en principio soporta 5 GHz - pero basado en lo que la aplicación anterior informó, supuse que este chip WiFi no puede manejar 5 GHz.

Por lo tanto, acabo de hacer estos cambios a mi red WiFi, con respecto a la captura de pantalla publicada anteriormente en OP:

Opciones de seguridad: volver a WPA2-Personal [AES]. sólo
Banda: 2,4 GHz sólo

... y finalmente, se conectó al Wi-Fi.
