Problem 12

A wireless router that uses Wi-Fi technology to connect laptop computers to the Internet has an Ethernet connection and wireless connections to multiple laptops. Consider data flowing from the laptops to the Ethernet. If the Ethernet connection operates at $1 \mathrm{Gbps}$, how many laptops must be connected to cause congestion on the Ethernet? (Hint: what is the maximum data rate of a single Wi-Fi connection?)
