You are in a school that uses a wireless network. The router is at the end of the corridor and your classroom has a poor connection. Which device, when added, can strengthen the signal in your classroom?

A wireless extender receives the router’s Wi-Fi signal and rebroadcasts it, helping the signal reach your classroom more strongly. DNS translates website names into network addresses, and a NIC connects a device to a network; neither extends Wi-Fi coverage.
