|AC = Alternating Current (the polarity of the current switches 50 or 60 times a second) = AC Power = the power you get from a wall socket. Depending on where you are, that's either ~ 110 volts or ~ 220 volts AC. |
Most high speed modems do not have a direct AC connection - they use an AC adapter = AC to DC adapter - the DC (Direct Current - the current always has the same polarity) end of it's connection plugs into a small port on the high speed modem.
Do you have more than one network port on your computer ?
If yes, the one nothing is connected to is being detected as working but it is going to generate a message in Windows that it's not connected. You can disable that message, or disable that network adapter in Device Manager, if you want to.
A standalone high speed modem has only ONE wired network port.
If your device has has MORE than one wired network port, it's NOT a standalone high speed modem, it's a combo router / high speed modem, and it has either a telephone jack or a coax cable connector that you plug a cable into or connect a coax cable to that connects to the internet, as well as, usually, one network port labeled WAN, and 4 other network ports.
DO NOT connect the network cable between your computer's wired network port and the WAN port - doing that may NOT allow a connection to the internet - connect it to any OTHER network port on the device.

CenturyLink™ High-Speed Internet/DSL Service
You have a combo wireless router / ADSL high speed modem.
It probably has 5 network ports on it, one labeled WAN, and 4 other ones.
You must connect a telephone cable to it to connect to the internet, that has ADSL service enabled for it. .
If you have just paid for the internet package, it may take several days until the ADSL internet connection actually works.
You often need to Restart Windows after you have made a change with your network cable connection, THEN you can be sure running IPconfig will show you the correct info.
The network cable that came with the high speed modem (or combo router / modem) is the correct type.
If you use another network cable you have, it may not be.
They are either
- wired "straight through" - all the wires connect to the same contacts in the connectors on both ends
- cross-wired - SOME of the wires are connected to different contacts in the two connectors.
When the end connectors on the network cable are clear, which is usually if not always the case, you CAN see which color of wire is connected to the contacts inside the end connectors.
Each of the 4 pairs of wires that are twisted around one another inside the cable's sheath are a color, and white with a stripe of the same color.
If you place the clear end connectors beside each other, same side up, facing the same direction, you can easily see whether the colored / striped wires are arranged the same or differently.
Whatever type of network cable it is, it it is getting a working connection, usually the led for the network ports it's plugged into light up on both ends when the cable is connected.
However, the computer often must be running for it's network port led to light up, Windows must have the drivers for the wired network adapter installed, and Device Manger must show the network adapter is working, and in a small number of cases, the wired network adapter on the computer may have no led.
If the network cable is the WRONG type, the led for the port will NOT light up on BOTH ends of the connection.
(If the led lights up on ONE end, the connection IS working.)
