Dziwny przypadek z wi-fi na linii Ubuntu-Linksys

[D-Vision]

Witam,

Z góry przepraszam, jeśli odpowiedź no moje pytanie jest już zawarta na tym forum. Googlałem ostro, ale żadnych rezultatów.

Od razu chciałem zaznaczyć, że wieczorem zrobię edit i podam szczegóły techniczne komputera, routera i co tam sobie jeszcze zażyczycie (bardzo proszę o instrukcję co jest wam potrzebne i JAK to zdobyć - jestem początkujący, wybaczcie). Temat zakładam już teraz, ponieważ jestem strasznie zdesperowany a nie chcę porzucać Ubuntu. Poza tym mam (zapewne złudną) nadzieję, że ktoś już miał podobny problem i będzie wiedział co możego powodować.

Sprawa wygląda tak:

Jest sobie laptop Toshiba Sattelite z Ubuntu na pokładzie, jest sobie router wi-fi Linksysa, do którego po kabelku leci internet od Vectry za pomocą modemu Thompson. Wszystko ładnie pięknie (na laptopie zapaliła się nawet lampka od wi-fi, na XP nigdy nie działała). Zasięg bije na głowę XP, wszystko łączy się automatycznie, nie ma problemów ani przy WPA, ani WEP, ani filtrowaniu MACów. Jednakże, co godzinę, dwie, trzy (różnie, czasem spokój trwa o wiele dłużej) połączenie nagle zostaje zerwane. I teraz zaczynają się rzeczy rodem ze strefy cienia:

1. Nie ma możliwości połączenia z routerem (i tym samym z internetem), nie pomaga ani restart karty sieciowej, ani systemu.
2. Na XP nic takiego się nie dzieje.
3. Przeprowadziłem test, do sieci dołączył laptop z Vistą. Wszystko cacy, dołączam ze swoim Ubuntu, mija jakiś czas, następuje rozłączenie mojego laptopa oraz równocześnie tego z Vistą...
4. Pomaga jedynie restart rotera (znaczy się listwy - router nie ma wyłącznika).

O co tu do ciężkiej cholery chodzi?! Problemów upatrywałem w routerze, z początku myślałem, że skoro rozłącza komputery i z Linuksem, i z Windowsem, a tym bardziej, że nie pomaga restart systemów, to to na pewno nie ich wina. Ale jesli pracuję tylko na systemach od Bill'a wszystko jest ok.

Naprawdę liczę na pomoc (i o nią błagam) bo jestem już na krawędzi wytrzymałości psychicznej.

Jeśli trzeba cos rozjaśnić - piszcie, dzwońcie, przyjeżdżajcie.

EDIT:
Dodam jeszcze, że przez cały czas wszelkie diody, zarówno na routerze jak i na modemie świecą prawidłowo. Zmnieniałem również zakresy pracy routeram więc zakłócenia też raczej odpadają. Zresztą - patrz: system z Redmond działa bez problemu...

Przerabiałem kiedyś coś podobnego z routerem Belkina - i do dziś nie wiem, czemu tak kaprysił...
Przede wszystkim, skoro zanika połączenie wifi pomiędzy komputerami a routerem - czy w takiej sytuacji jesteś w stanie podpiąć się do niego przy pomocy kabla? Napisz, czy jego ustawienia pozostają niezmienione - ciekawi mnie głównie to, czy w takiej sytuacji router nadal jest online i twierdzi, że transmisja wifi funkcjonuje bez zarzutu.

[D-Vision]

Właśnie próbowałem podłączyć się do routera (po rozłączeniu) kablem - nic z tego, efekt taki sam jak w przypadku połączenia bezprzewodowego...

Router to Linksys BEFW11S4. Karty sieci bezprzewodowej niestety nie potrafię zidentyfikować spod Linuksa, a pamiętam jedynie, że to Realtek. Komputer to Toshiba Satellite L40.

Naprawdę nie wiem co robić... Zanim wydam pieniądze na nowy router wolałbym się upewnić, że to wina routera.

[k2cl]

...czyli jeśli router powie Ci "dobranoc", nie da się do niego w żaden sposób podłączyć? Co w takim razie wyświetla przeglądarka internetowa, gdy próbujesz wejść na stronę konfiguracji routera?

[D-Vision]

Dokładnie tak. Wyświetla po prostu "Nie można wyświetlić strony", tak jak przy każdej innej, kiedy przeglądarka jest offline. I nie ma zlituj: wyłączanie karty wireless, restart systemu, w przypadku windy jeszcze opcja "napraw" - nic nie skutkuje. Magiczne pstryknięcie on/off na listwie działa za to zaskakująco dobrze problem w tym, że to żadne rozwiązanie. Oczywiście próbowałem ustawiać router na wszystkie możliwe sposoby, w tym na ustawieniach fabrycznych - ciągle to samo.

[k2cl]

No dobrze... Jak w takim razie wyglądają parametry połączenia (chociażby wyniki ifconfig i route)? Jakie pojawiają się różnice, kiedy router przestaje z Tobą współpracować?

[D-Vision]

Ok, sprawdzę to po powrocie z pracy i zrobię edit. Dodam jeszcze, bo może to istotne, że zerwanie połączenia występuje bez względu na aktywność sieciową, potrafi zerwać się przy gołym pulpicie równie dobrze jak przy streamingu.


EDIT:

Oto wyniki...

EDIT:

Przypomniałem sobie o tym temacie więc dodam, że problem zniknął w momencie przejścia na Ubuntu 11.04. Widać 10.04 nie radził sobie zbyt dobrze we współpracy z tymi routerami Linksysa (swoją drogą to dla mnie dalej dziwne.)

Pozdrawiam i dzięki wszystkim udzielającym się w temacie. Do zamknięcia.
