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 are connected
over WiFi must use network IP addresses on the same network as the router. The simplest way to do this is to
configure each computer to obtain an IP address automatically using DHCP.
Some service providers require you to use the MAC address of the computer initially registered on the account. You
can view the MAC address on the Attached Devices page.

By default, the router is set with standard LED settings. If you turned off the LEDs except the Power LED, you must
