Cześć,
Problem występuje na Linux Mint 17.2 Cinnamon 64-bit, wersja 2.6.13, Jądro Linux 3.16.0-38-generic.
Sieć jest wykrywana, ale czasem się z nią łączy a czasem nie. Jak się już połączy to non stop przerywa. Zdarza się też tak, że pokazany jest brak połączenia a internet śmiga, ale zazwyczaj krótką chwilę. Na tym samym komputerze zainstalowany jest Windows 7, tam problem jest podobny. Wcześniej, kiedy pojawiał się problem, po kilkukrotnym włączeniu i wyłączeniu WiFi problem znikał na dłuższą chwilę, teraz już to nie pomaga. Na komputerze obok (Windows 7) nie ma problemu z połączeniem. Na komputerze bez Linuxa siła sygnału jest stała, na tym, z którym jest problem znacząco się waha od 30% do ponad 60%.
Proszę o pomoc.
Pozdrawiam

Musisz wziąć pod uwagę ze na komputerze obok (który działa prawidłowo) jest zupełnie inna karta wifi.
Tu raczej bym widział problem sprzetowy skoro na windows jest sytuacja analogiczna.
Nie podałeś nam jaką kartę wifi masz w tej felernej maszynie.

Po komendzie lspci,
Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
Maszyna: Asus x70s
Różnica między Linuxem a Windows 7 na tym komputerze jest taka, że Windows radził sobie z tym problemem przez wykrywanie problemu, chociaż dzisiaj i to nie pomagało.
P.S. Dzisiaj od 8:00 zostawiłem Linuxa samemu sobie, i po dwóch godzinach się połączył, ale internet nie działa jak szybko jak powinien.

Taka luźna propozycja.
Cell 8 masz na sąsiednim kanale sygnał prawie tak silny jak twój.
Może go skutecznie zakłócać.
Ja bym zaczął od zmiany kanału w routerze na mniej podatny na zakłócenia.

Wygląda na to, że to słuszna diagnoza. 5 [m] bliżej routera nie ma żadnych problemów. Mieszkanie wynajmuję, nie znam loginu ani hasła, więc kanału na razie nie zmienię.
Wielkie dzięki za szybką pomoc.
Pozdrawiam
