5G signal on orange, AIR signal off

[Nedu]

Hello, 

We recently moved into our new home, the house comes preinstalled with a smart home access point including RUCKUS R510 routers. I have never used a RUCKUS system before or a “smart house” for that matter. So my concern, there are two RUCKUS routers in the house. On one router, the PWR indicator is green but blinking, CTL is solid green, 2.4G is solid green. However, AIR signal is off, 5G signal is on orange (which is my main concern). On the other RUCKUS R510 router, PWR is on blinking green, CTL is also on blinking green (slower blink compared to the PWR indicator). All other indicators in this router are off (occasionally, I have noticed this router go off on its own and back on, all indicators remain as mentioned above). I have researched and read in some forums here that when the 5G indicator is on orange, it means no client is connected to it. Now, after installing my internet I have not seen an option of choosing between 2G or 5G connectivity. Hence, my questions are 1) Is it possible my RUCKUS R510 routers are not working? 2) how do I configure the routers so I can see the 2G and 5G connections in my WiFi selections? 3) Why is the AIR signal off?
