If the error persists, you have a hardware problem and should contact NETGEAR technical
support.
Test LED Never Turns Off
When the wireless controller is powered on, the Test LED turns on for approximately 2
minutes and then turns off when the wireless controller has completed its initialization. If the
Test LED remains on, there is a fault within the wireless controller.
If the Test LED is still on more than several minutes minute after power-up:
• T
urn the power off, and then turn it on again to see if the wireless controller recovers.
• Rese
t the wireless controller’s configuration to factory default settings. Doing so sets the
wireless controller’s IP address to 192.168.0.250. This procedure is explained in Reboot
or Reset the Wireless Controller o
n page 139.
If the error persists, you might have a hardware problem and should contact NETGEAR
