Ha pasado casi un mes y Internet me ha decepcionado, no puedo encontrar una solución a este problema.
Mi WiFi se desconectará intermitentemente entre 30 segundos y 30 minutos. A menudo tendrá un ataque de desconexión continua si intento volver a conectarlo.
El problema persiste en WPA2-Enterprise (autenticación: PEAP, autenticación interna: MSCHAPv2), WPA/WPA2 estándar e Internet abierto.

Además, incluso cuando Internet funciona, normalmente pierdo ~15% de los paquetes, mientras que en mi partición de Windows pierdo <1% después de 30 minutos de hacer ping. No estoy seguro si esto está relacionado o no.
