A mediados de 2009, el problema de la Wi-Fi de 5 GHz de la Macbook Pro

2

Ayer, de repente, el WiFi de mi Macbook dejó de funcionar en la escuela.

Tengo razones para pensar que solo se efectúa la banda de 5GHz. La conexión personal de Hotspot a través de mi iPhone todavía funciona y mi Wifi en casa también funciona.

Hay varias redes (por ejemplo, eduroam) en mi escuela, pero ninguna de ellas funciona. Mi macbook se conecta a las señales de 5 GHz allí y muestra la intensidad de la señal completa. Hay BSSID de 2.4GHz pero comparten el mismo SSID y no pude averiguar cómo forzar el macbook para que se conecte a los 2.4GHz ...

Ejecuto OSX 10.9.5.

Pings to www.google.com o 8.8.8.8 timeout. En realidad, ni siquiera puedo hacer ping a los enrutadores de wifi. El único tráfico que veo en la red (usando snitch) es el tráfico de respuesta de MDNS ...

Este es el registro para encender wifi y conectarse a una señal:

¿Alguien tiene una idea de qué más podría probar?

Aquí hay un glympse en el tráfico de DNS en caso de que pueda ser útil:
