Netgear R6220 - AC1200 Smart WiFi Router with External Antennas 사용자 설명서

You can use the LEDs to identify setup or performance problems in the router and to isolate 
the cause.

After you turn on power to the router, make sure that the following sequence of events 

occurs:

When power is first applied, verify that the Power LED 

 is lit.

After about two minutes, verify the following:

The Power LED is solid green.

The WANLED is lit.

The WiFi LED is lit unless you turned off the wireless radio.

You can use the LEDs on the front panel of the router for troubleshooting.

Do the following:

Make sure that the power adapter is securely connected to your router and securely 
connected to a working power outlet. 

Check that you are using the power adapter that NETGEAR supplied for this product.

If the Power LED blinks slowly and continuously, the router firmware is corrupted. This 
can happen if a firmware upgrade is interrupted, or if the router detects a problem with the 
firmware. If the error persists, it is likely that a hardware problem exists. For recovery 
instructions, or help with a hardware problem, contact technical support at 

When the router is turned on, the Power LED turns amber for up to two minutes and then 
turns green. If the LED does not turn green, this indicates a problem with the router.

If the Power LED is still amber three minutes after you turn on power to the router, do the 
following:

Turn off the power and then turn it back on to see if the router recovers.

Press and hold the Reset button to return the router to its factory settings.
