new PC not work with existing router, but works fine when directly connecting to cable modem
I bought a new desktop PC (eMachine ET1331G-03W from WalMart) with windows 7 installed, but I can not access internet by connecting to my existing wireless router(LinkSys BEFW11S4) with wired cable. Though all other existing desktops and laptops have no problem connecting to the same router. However, the new desktop PC works fine and able to connect to internet if I bypass the router and directly hook up with the cable modem.
