WiFi Settings
Make sure that the WiFi settings in the computer and router match exactly. The WiFi network name (SSID)
and WiFi security settings of the router and WiFi computer must match exactly.
If you set up an access list on the Advanced Wireless Settings page, you must add each WiFi computer’s
MAC address to the router’s access list.
Network Settings
Make sure that the network settings of the computer are correct. Wired computers and computers that
