AskUbuntu'da başka sorular okudum, ancak Linux'ta yeni olduğum için sorunu çözemedim.
Sorun Ubuntu 14.04'teki Wifi bağlantısının kararsız olmasıdır. Bir süreliğine wifi'ye bağlanır, ancak 5 dakika sonra sadece ağların çoğunu bulamaz (bazılarını bulur).
Fare Bilgisayarından satın aldım. Ancak Windows 8.1'de (çift önyükleme) kararlı olduğu için bir donanım sorunu gibi görünmüyor.
Aşağıdaki çözümleri denedim.
/Etc/modprobe.d/iwlwifi.conf dosyasına "options iwlwifi 11n_disabled = 1" ekleyin
IPv6'yı yoksay
NetworkManager'ı yeniden başlat
Hiçbiri sorunu çözmedi.
Aşağıda Ubuntu bilgilerim yer almaktadır.

======== Done ========
Şimdiden teşekkür ederim.
btw, Ubuntu okuyorum çünkü Windows ile başa çıkmaya çalışmaktan daha eğlenceli buldum. Ask Ubuntu topluluğundan dolayı ana platformumu Ubuntu'ya geçirmeye karar verebilirim. Hepinize teşekkürler Ubuntu meraklıları.
Yönlendiriciye bağlanmak için WPA kullandığımda bunu fark ettim. WPA2'yi kullanmayı deneyin - şimdi benim için iyi çalışıyor.
