Luke is setting up a wireless network at home and is adding several devices to the network. During the setup of his printer, which uses 802.11g standard, he finds that he can't connect to the network. While troubleshooting the problem, he discovers that his printer is not compatible with the current wireless security protocol because it is an older version of hardware. What wireless network security protocol can Luke implement on the WAP so that the printer can connect to his wireless network?
