Section 10 - Troubleshooting
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 conguration, 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.
Problems with Date and Time
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 nd that the date and time stamps are not accurate, conrm that the wireless controller can reach the
Internet.
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 257).
• Be sure you entered the appropriate IP address range if the access points operate in dierent VLANs,
reside behind an IP subnet, or operate in standalone mode (see “Step #1: Enable DHCP Server (Optional)”
on page 25).
• If you are using a rewall, unblock the UDP port number for each access port in the rewall.
• Be sure each access point is using a unique IP address (see “AP Discovery Methods” on page 75). 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 27).
