Hotspot wifi (hostapd) et limitation du nombre de clients
Bonjour,
Je monte un hotspot wifi sur une DELL équipé d'une carte wireless Intel AX201 avec hostapd et dnsmasq. Pas de connexion bridgée.
L'idée est de délivrer un accès à un serveur web autonome a des devices (iPhone et iPad) en espace clos.
La configuration fonctionne bien et j'ai accès depuis les devices à mon serveur.
Une limitation est apparue sur le nombre de device qui peuvent se connecter.
Seuls 12 devices peuvent s'incrire sur le wifi proposé, le 13ème se prend un refus de connexion. Si je déconnecte un device, je peux connecter le device qui vient de se faire refuser la connexion.
Avez-vous des pistes qui pourraient faire sauter cette limitation ?
Merci
Yves
