Question about internet ten points best answer!?

On my modem there are lights that flash whenever data is being sent or received, basically whenever somebody is on the internet. Sometimes they flash when im not on the internet though, i have a multi security function set up on my wireless router (TKIP and AES) and nobody will have guessed the passcode, but i do have a wii console that is constantly connected to the internet (wii connect 24), so how come the lights that show internet activity flash sometimes when im not on the internet, because normally the wii only connects to the internet to receive message but even after the lights flash there are no messages on the wii, can anybody help with this?



These lights are normal, as any two directly connected devices will talk to each other, whether they're passing user traffic or not.





A big culprit is ARP traffic, or "Address Resolution Protocol". Your computer and router both maintain small databases linking MAC (media access control) addresses to IP addresses, and those records expire after a set amount of time, so the two devices keep each other updated.





To see this yourself, use a protocol analyzer such as wireshark (www.wireshark.org/) to see all the bits of traffic going from your computer to the router in real time. They're mostly just making small talk. :) The router and the modem are essentially doing the same thing.




they would be flashing because your wii would be checking the internet for updates/messages even though there are none there
