What do the LEDs (lights) on my Linksys EA9400 and EA9500 mean

The Linksys EA9400 and EA9500 are Smart Wi-Fi Routers with Tri-Band technology.  These routers allow a faster and a more productive wireless connectivity through blazing connection speeds, and stability to every device on your Wi-Fi network with their eight (8) Gigabit Ethernet ports and MU-MIMO technology.​
