Ma bbox apparaît deux !

C'est une Box qui doit pouvoir gérer deux fréquences (en principe 2.4 GHz et 5 GHz)

Tu as sa notice ?

Effectivement : Wi-Fi 2.4GHz et 5GHz
WPA2 / AES ne résolvait rien.
J'essaye WPA / AES...
Je reviens vers toi pour te dire.

Second, if your router is capable of N speeds, you may have better connectivity with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz, although it is likely to affect N speeds. I also have better luck with a fixed channel, either 1, 6 or 11, rather than automatic channel selection. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.

Veuillez vérifier les paramètres dans le routeur. WPA2-AES est préférable ; pas de mode mixte WPA et WPA2 et certainement pas de TKIP. Deuxièmement, si votre routeur est capable du mode N, vous pouvez avoir une meilleure connectivité avec une largeur de canal de 20 MHz dans la bande 2,4 GHz au lieu de 20/40 MHz automatique, bien que cela puisse affecter mode N. J'ai aussi plus de chance avec un canal fixe, 1, 6 ou 11, plutôt que la sélection automatique des canaux. Assurez-vous également que le routeur n'est pas configuré pour utiliser uniquement du mode N; Auto B, G et N sont préférés. Après avoir apporté ces modifications, redémarrez le routeur.
