If you need to connect to your computer a device such as a wireless router or modem that needs an ethernet cable to operate faster, you can use an ethernet to USB adapter to solve the problem. An ethernet to USB adapter is a small accessory that modifies an ethernet cable so that it is compatible with a USB port (or so that a USB port is compatible with an ethernet cable) and it sends signals from the external device to the computer more rapidly. The adapter is so easy to use that you won't even need to read the directions once you make the purchase.
Attach one end of an ethernet cable to the ethernet port on the ethernet to USB adapter. An ethernet cable looks like a large telephone line and an ethernet port looks like a telephone jack.
Locate the ethernet port on the device that you want to connect to the computer.
Insert the other end of the ethernet cable that's attached to the ethernet-to-USB adapter into the ethernet port on the device.
Find a USB port on the computer. A USB port is labeled "USB" and it will also have an image that resembles a triton, or a three-pronged spear.
Insert the USB end of the ethernet-to-USB adapter into the USB port.
