Cada 10-15 minutos, mi conexión a Internet falla de la siguiente manera:
- No se pueden cargar sitios web
- No se puede conectar a Dropbox
- No se puede conectar a IRC
- Skype todavía funciona
- Slack todavía funciona
- Todavía puedo conectarme a mi enrutador y módem
Después de mucho buscar, creo que este es un problema de DNS. He intentado utilizar tanto los servidores DNS de mi ISP como los servidores DNS de Google, pero el problema persiste.
Cuando me desconecto de mi red Wi-Fi y me vuelvo a conectar, el problema desaparece y todo funciona durante otros 10-15 minutos.
Aquí hay algunos resultados de algunas ping
pruebas cuando aparece el problema:
