I have a router, which in turn is connected to my computer. For months now, the light on my router, indicating the WAN activity, is blinking it's a$$ off. It's like someone is accessing the router, not once, not twice, but a gazillion times per second. Today I thought, enough is enough, I downloaded TCPview and connected the WAN line directly to my computer, bypassing the router. I immediately noticed the light on my NIC blinking, so I started TCPview. Except for MSN Messenger connecting to the MS Passport servers, nothing happened in TCP view. Also my 'software light' (the two computers indicating network activity in Windows) didn't light up. But my NIC lights were blinking^2000/sec. What can it be? Could it be DHCP broadcasts? My provider uses DHCP for connections (meaning I can directly put in any computer on the modem, without configuring), could it be it sending too much broadcasts around (or something similar)?
