    One of two places. Either to a network device such as a computer or printer. or to your cable modem to add internet to your network. The wires can be any color, it is the port that the wire is plugged into that determines where the other end should go. You have one WAN port and typically 4 LAN ports on your average router. The WAN goes to your modem, the LAN goes to any home devices you want to hard wire to the network.

    Network wire colors aren't standard. You have to know exactly what your'e doing to be able to connect those wires properly.

    A computer or a switch, usually? IF there's a grey or yellow one, that should go into the modem, it will have an icon that looks like a little globe, or could have like the antenna wave looking thing. then the other cable will go into a computer or a switch that then has another cable going to each of the various devices.

      Since there is no standard for the colours of ethernet cables, any coloured one can be supplied and/or used for any connection.

    The Blue Cable is an Ethernet Cable. It plugs into one of the Four Ethernet Ports on the Router and the other end plugs in the Ethernet port on your PC.

      The Ethernet cable *from* the router does not plug back into the router!

    There are two scenarios here.

    1) you have a modem with a router built in. The cable (usually coax, like you used to put on a TV) attaches to the modem for your internet signal. You can then connect to the router using WIFI. Some routers also have Ethernet ports, which you can use a LAN cable to connect devices such as desktops and DVRs.

    2) You have a modem and a separate router. Again the coax cable should connect to the modem, however now there is an Ethernet cable which connects from the modem to the router. The Ethernet cable will go into the Ethernet port n the back of the modem and will connect to the router in the port on the back which is labeled something like "Up-link". Once the router is configured for your home network, you can connect wirelessly to the router OR use an Ethernet cable to wire devices in direct. Note, you don't want to connect a device into the modem or to the router's UP-LINK port. That is only for the modem.

    '

    Chances are, your blue cable is an Ethernet cable. You can tell because it LOOKS like a phone connector, only instead of 2 or 4 wires in the connector, it has 8. You can turn it over and look into the clear connector to count the wires.

    You'd need to be more descriptive. The color of the cable is arbitrary. It could easily be yellow, gray, white, etc.

    The blue wire is the incoming internet signal the wire that's coming out of the wall should be and ethernet wire that's the one that goes to the blue plug the yellow plug goes to the back of your computer. Of course if you already have a cable modem internet. And for some reason it's not already wireless you're going to take the yellow wire that's coming out of your cable modem and plug one of the yellow wires into the blue socket so that you have an incoming signal going to your router. Then you can use one of the yellow sockets to plug into the back of your computer or you can get a wireless USB adapter if you have a desktop for the wireless signal or if it's a laptop it should be able to pick it up.

      The only thing we can say with reasonable certainty is that the blue wire is an ethernet cable. We can also with reasonable certainty say that ONE END of it plugs into an ethernet port of the router.

    Helps to know exactly what the "blue wire" is. Can't help with such vague descriptions. If it is an Ethernet cable, you simply plug one end into your modem and the other end into the router's WAN port. Then, you grab another Ethernet cable to plug into your PC.

    Or to the computer if it is not a wireless connection.

    Probably to your cable modem.

    But I'm just taking a good guess.
