Internet/Nätverk kopplar ifrån på en dator men inte på en annan

Ja som sagt. Internet/nätverk kopplas bort i tid och otid, det är precis som att någon drar ur sladden fastän den sitter i. Enda sättet att lösa det är att dra ur nätkabeln till routern och sätta i den igen.

Funkar problemfritt på en annan dator. Osäker på vad det är för OS på den, men jag tror det är XP. Min har Win 7.
Ibland tar det en halv dag, ibland en halv minut. Men alltid återkommande.

Tele2 2mbit om det har någon betydelse.

Om någon blir klokare..

Det är en 3Com 3CR858-91.
Japp det är dem. Har provat med annan kabel.
Har även fått veta att den andra datorn också kopplas ifrån. Svårt att säga om det är lika ofta då den inte används i samma utsträckning.
Installerade om datorn igår med samma OS (Win 7 x64) Men det hjälpte inte.
Routern har senaste firmware.

Har återställt routern och lagt in användarnamn +lösen igen. Kan ju va att man gjort nån dum ändring man inte borde ha gjort ^^
Bara vänta och se. Bör märkas på ett par dagar om man får några disonnects.

Ptja det är gammalt, men knappast sen vi köpte routern, för den har säkert 5-6 år på nacken. Ett halv år kanske.

Jag vet inte ens om jag kan lägga in en statisk ip. Nätverk och internet är inte min starka sida. Vet bara att vi kör PPPoE och måste skriva in lösenord och skit i routern annars funkar inget. Vart lugnt i 9h nu i alla fall efter att jag resettat till fabriksinställningarna (och fixat med användarnamn+lösen till anslutningen såklart).
