Re : ma wifi lente et instable;
Bonjour,
@ rafiobetay
* freebox_lamimie Infra 11 54 Mo/s 54 ▂▄__ WPA1 Tu devrais essayer de passer en chiffrement WPA2, voir § 1 [Tuto] Pas de Wi-fi ? Eléments importants à vérifier.
Et essayer un canal 6 > quel-canal-wi-fi-choisir-pour-optimiser-son-debit/
Quel est ton modèle de Freebox ?
Rajout.
Tente aussi :
sudo iwconfig wlo1 power offpour désactiver la gestion de l'énergie de la carte wifi.
