3. Which installation method will allow connectivity for a new wireless network?
set up WEP on the access point only
• set up open access on both the access point and each device connected to it
set up full encryption on the access point while leaving each device connected to the
network open
set up full encryption on each device of the WLAN while leaving the access point
settings open
