• Radio Settings page: Ensure that the SSID is the same on clients and the
access point.
• Security page: Ensure that Encryption is the same on clients and the access point.
• Authentication page: Ensure that the Local MAC Authentication System Default is
set to Allow. Ensure that 802.1x Authentication Settings are correct.
• TCP/IP Settings page: If the DHCP Client is set to Disabled, then ensure that the
access point IP Address is within the same subnet as the wired LAN.
If necessary, reset the access point to the factory defaults.
