Witam!

Otóż istnieje pewien problem z wymienionym w temacie odbiornikiem sieci D-Link Wireless G. Na pokładzie komputera zintegrowana karta sieciowa Intel Corporation 82541EI Gigabit Ethernet Controller. Od jakiegoś czasu urywa sieć bezprzewodową, bądź sygnał jest wyjątkowo słaby (googli nawet nie odpala). Próbowałem wielu spraw ale nie mogę temu problemowi zaradzić.

Prędkość łącza to 15Mb/s. Z routera rozdziela je na dwa komputery. Rozłącza internet nawet gdy tamten drugi jest wyłączony. Zmiana Network managera na wicd nic nie daje. Ustawienie odbiornika i routera wyzej również. Chłodzenie modemu + routera + odbiornika również. O dziwo zaskakuje mnie, że pokazuje czasem na Network Managerze 70% mocy sieci a internet dalej słaby. Na windowsie sieć też słaba lub nie działa. Czasem internet chodzi normalnie.Na drugim komputerze też potrafi paść (nie pada na obu jednocześnie zazwyczaj). Gdy komputer podpięty bezpośrednio do kabla - net z reguły chodzi lub pada. Robiłem test na speedtest.net i wygląda na w normie. Telefon do dostawcy neta pomógł tylko na chwilę.

Oto co wykazał dmesg | tail -n 100 podczas dostępu do sieci:

Obawiam się że to coś z routerem. Zwróciłem szczególną uwagę na te reason: 2, reason: 3, reason: 6. Wygląda to jakby wysyłał zapytanie do routera, dostawał odmowę i próbował się połączyć aż do skutku. Nie wiem czy dzwonić znowu do dostawcy neta czy co. Jak myślicie, co jest grane? Mrugnięcie

Czasami jest tak, że nawet ekspertowi potrzeba idioty, żeby się z boku przyjrzał, w związku z czym pytanie takie...
Czy mógłbyś zapisać konfig routera do pliku i zresetować go ? Miałem kiedyś ciekawostkę taką z D-Linkiem, że kiedy było włączone równoważenie pakietów (QoS), to sieć kablowa zdychała. Z kolei kiedyś na Asusiaku miałem błąd z zabezpieczeniami. Na czysto, wpuszczając jak leci internet chodził jak burza. Cokolwiek innego - dupa.

Chodzi mi o plik konfiguracyjny routera. Zazwyczaj opcja backupu ustawień jest w menu Administration.

ok jestem w menu-administracja-narzędzia sieciowe. Nie mogę jednak znaleźć tego backupu. Chodzi o wyświetlanie tablicy routingu? Mrugnięcie

Takiego cuda tam nie ma... To było jakoś ręcznie wmontowywane?

Nie kojarzę ani jednego routera, który by nie dawał opcji zapiania swoich ustawień,
Czy możesz podać mi konkretny model tego tałatajstwa ? Poszukam gdzieś instrukcji obsługi i może coś namierzę.

Generalnie chodzi o opcje typu "zapisz ustawienia", "config backup", "save profile", "store settings"... ?
