This has probably;y already been answered, but I can't find it. My router has 5 Ethernet jacks (1 WAN and 5 LAN)., What is the difference between WAN and LAN? Does it make any difference which jack I connect the computer or other devices (printers, etc,) to?
Solved! Go to Solution.
wan is for your actual internet connection. Verizon brings internet either through the ethernet cable, or through the coax.
So if the ethernet WAN is open, then don't plug anything into it. Only use the 1-4 ports to connect your home devices.
Wan is only used when the router is receiving information
What does that mean? As Hubrisinxs stated, the WAN port is used only if you have a cat5 connection to the ONT. In that case, data is both sent and received to the internet over that port.
yeah the more I read it the more it doesn't make sense....basically your not gonna put anything in that port as far as electronic wise for computers or devices that aren't in direct relation to receiving internet services
Wan is Wide area Network and the Lan is Local Area Network
Pretty much the Lan info is sent to the wan and sent out to the internet you won't put anything in the wan unless its the connection your getting from an isp requires you to put it in there.
But Hubs is right
