Mid 2009 masalah Macbook Pro 5Ghz Wifi

Kemarin, tiba-tiba WiFi Macbook saya berhenti bekerja di sekolah.

Saya punya alasan untuk berpikir bahwa hanya band 5GHz yang terpengaruh. Koneksi Hotspot Pribadi melalui iPhone saya masih berfungsi dan Wifi saya di rumah juga berfungsi.

Ada sejumlah jaringan (misalnya eduroam) di sekolah saya tetapi tidak ada yang berfungsi. Macbook saya terhubung ke sinyal 5GHz di sana dan menunjukkan kekuatan sinyal penuh. Ada 2.4GHz BSSIDs tetapi mereka berbagi SSID yang sama dan saya tidak tahu bagaimana memaksa macbook untuk terhubung ke 2.4GHz ...

Saya menjalankan OSX 10.9.5.

Ping ke www.google.com atau 8.8.8.8 batas waktu. Sebenarnya saya bahkan tidak bisa melakukan ping pada router Wifi. Satu-satunya traffic yang saya lihat di jaringan (menggunakan snitch kecil) adalah traffic MDNSresponder ...

Ini adalah log untuk menyalakan wifi dan menghubungkan ke sinyal:

Adakah yang tahu apa lagi yang bisa saya coba?

Berikut ini adalah glympse ke lalu lintas DNS jika itu dapat membantu:
