Using the Reset Button to Restore Default Settings

If you cannot access the wireless controller's management interface for some reason, press the reset button on
the front panel to restore the factory default settings.
To clear all settings and restore the factory default values:
1. Press and hold the reset button for at least 15 seconds.
2. Release the reset button. The reboot process is complete after several minutes.
Note: After restoring the factory default configuration, the wireless controller's default LAN IP address is 192.168.10.1,
the default login user name is admin, and the default login password is admin.
The Date and Time page shows the current date and time of day. The wireless controller uses the Network Time
Protocol (NTP) to obtain the current time from one of several network time servers on the Internet. Each entry in
the log is stamped with the date and time of day.
If you find that the date and time stamps are not accurate,
• Confirm that the wireless controller can reach the Internet.
• If you have just configured the controller, wait for at least 5 minutes, select Administration > Date and
Time > Time Zone, and recheck the date and time.
• Verify your internet access settings.
If you find that the time is off by an hour,
Select Administration > Date and Time > Time Zone, and view the current date and time settings.
•
Toggle the switch to Enable or Disable "Daylight Savings", then click Save.

Discovery Problems with Access Points

If the wireless controller does not discover any or all access points:
• Be sure the wireless controller is connected to the LAN (see "LAN Port LEDs Not ON" on page 366).
• Be sure you entered the appropriate IP address range if the access points operate in different VLANs,
reside behind an IP subnet, or operate in standalone mode (see "Step #1: Enable DHCP Server (Optional)"
on page 28).
• If you are using a firewall, unblock the UDP port number for each access port in the firewall.
• Be sure each access point is using a unique IP address (see "AP Discovery Methods" on page 95). If
more than one access point has the same IP address, only one of them is discovered. In this case, add
the access point to the managed list, change its IP address, and then run discovery again to discover the
next access point with that IP address (see "Step #3: Select APs to be Managed" on page 30).
