I have a LAN network at home and it has been working fine for almost a year. But recently, I keep getting disconnected and when I do, all other computers get disconnected to. Only when I plug my cable out from the router, the other computers can reconnect. Whenever I try to reconnect, I am only able to stay online for about 3 seconds. After that, I wont be able to load a page even though it says I am still connected to the LAN. Does anyone know whats wrong? Whether it's my Ethernet card or a trojan or something? It's definitely not my ISP since I called them up.
