Why AP LED is blinking in blue ?

A blue blinking Zyxel AP light can indicate a few things.

1. A blinking light blue LED on your Zyxel access point typically indicates that the AP is searching for an uplink signal. This could mean that the AP is trying to connect to a root AP in a mesh network.
2. If the AP is blinking blue slowly and you cannot find your SSID, it may be performing a Dynamic Channel Selection (DCS) scan and selecting a Dynamic Frequency Selection (DFS) channel. This process can take up to 10 minutes, during which time the AP will temporarily stop all wireless services。
