router problems ei.. :\.
things to do.
*check your wires some of them are broken which makes it wiggly and disconnected then connected to sites.
*Try the other computers, maybe others would work.
*try to remember..what you did before that makes it stop, on disconnecting.
Not a PC magician to solve your problem..but if you would explain it simple way..
cause when i read your post it sounds like a bit scientific xD.

2 of the computers i think doesnt work fine.... but we are connected with the same router.... i think the problem is the lan ip.... i always re cinfigure my ip adress so that i will have no identical ip in other computer... but it doesnt work... uhm .... way back before we reformat this pc, the last configure or what make my internet connection fine but i forgot to do it again... so could you make it???
