Asus 1215N, Broadcom Corporation BCM4313 - brak połączenia z WiFi

[Hiran]

Mam bardzo dziwny problem z moim asusem na którym postawiłem ubuntu 14.04. Otóż nie jestem w stanie połączyć się z moim wifi. Ubuntu pokazuje ze jest połączony do wifi ale jak wpiszę w terminal "ping wp.pl" to dostaję w oczy komunikatem unknown host. Identycznie jest z przeglądarką. Tak jakbym wcale do wifi podłączony nie był. Dodam że mój PC stacjomarny tez jedzie na wifi i na nim wszystko śmiga, no i przed przejściem na 14.04 miałem 13.10 i tam było ok.
Reinstall robiłem i nie pomogło.
Jakieś propozycje?

Dodam jeszcze że z niewiadomego mi powodu internet wrócił więc zrobiłem upgrade oraz zainstalowałem trochę softu ale po restarcie znowu neta brak...
Wifi jest zabezpieczone WEP'em z współdzielonym kluczem. Wiem że wep jest beznadziejny ale mieszkam w domu jednorodzinnym więc nikt mnie nie atakuje, a to zabezpieczenie jest tylko po to aby jakiś randomowy sprzęt sam automatycznie się z siecią nie łączył.

Edit:
Namierzyłem coś ciekawego, jeśli podłącze lapka kablem do internetu i odłączę to wifi śmiga ale tylko do restartu. Może ktoś kumaty naskrobać kilka linijek które zasymulują to abym miał rozwiązanie na szybko, do momentu aż się z problemem uporam?

Niw wiem czy to coś zmienia ale komendy wykonywałem z podpiętym kablem. linux-headers-generic już miałem więc zrobiłem mu reinstall.
Teraz karta wifi wogule nie wykrywa żadnych sieci bezprzewodowych.

Edit:
Dziwnych zdarzeń ciąg dalszy. jak bawiłem się żeby udostępnić sobie internet kablem z komputera to nagle zauważyłem że wifi zaskoczyło.... Nie wiem co to spowodowało ale jak znajdę przyczynę to dam znać Może jeszcze jeden restart był potrzeby.... niewiem.

Edit 2:
Dobra, wifi zaskoczyło, ale działa tak jak wcześniej. Natomiast zauważyłem coś ciekawego. Ping do mojego routera o adresie 192.168.1.1 działa natomiast już kolejny adres (coś moich dostawców od neta) nie.

To co zwraca ping, gdy sprawdzasz DNS od Google:

ping -c 5 8.8.8.8

Pokaż również, co zwraca polecenie:

I jeszcze małe uzupełnienie. Fragment polecenia tracert z mojego pc. Z ubuntu ping działa tylko do routera. Reszta nie odpowiada.

Sprawdzałem też na live 14.04 i wszystkie objawy są identyczne.

Tak sobie pomyślałem, może to wina sterowników tej sieciówki? Może zainstalowanie innych albo starszych rozwiąże ten problem?

W takim przypadku możemy raczej odrzucić źle skonfigurowanego firewalla na komputerze. Pozostaje konfiguracja routera.

Tak sobie pomyślałem, może to wina sterowników tej sieciówki? Może zainstalowanie innych albo starszych rozwiąże ten problem?

A masz możliwość sprawdzenia na innej sieci? Próbowałeś podłączyć się do innej sieci WiFi i sprawdzić, czy problem dalej się powtarza? Jeżeli w przypadku innych sieci WiFi problem będzie się powtarzał, to wówczas można zacząć żonglować dostępnymi sterownikami. Tyle że twoja karta, powinna poprawnie pracować na obecnie zainstalowanym.

Temat do zamknięcia, winne problemowi były zabezpieczenia wifi. Najwyraźniej linux wep'a nie lubi, bo jak zmieniłem szyfrowanie na wpa to problem znikł.

Jak problem rozwiązany, to edytuj swój pierwszy post i na początku tytułu dodaj [SOLVED] - ułatwi to innym z podobny problemem znalezienie rozwiązania.

[Hiran]

Sory za wprowadzone zamieszanie ale problem znowu się pojawił. Przez jakiś czas było ok a teraz znowu nie może się z wifi połączyć.

Teraz już zabezpieczenia sieci chyba odpadają więc należałoby pobawić się z sterownikami.

Edit:
Problem został rozwiązany. Wystarczyło że zmieniłem ip routera z 192.168.1.1 na 1.2. Nie bardzo rozumiem co powodowało ten problem no ale...
