Docsis 3.1 receive light green Arris SB8200

Just this week I notice the receive light on my arris sb 8200 is green instead of usual blue. Restarted modem and remained blue for 10 minutes and then green. 
any suggestions would be appreciated

Question. Are you actually experiencing any connectivity problems or are you just focused on the indicator light ?

Good question! So I restarted the modem and with the receive light indication Docsis 3.1 (blue light) I conducted a speed test then ten minutes later after light turned green, I conducted a second speed test and they appear to be in the same ball park. 
it’s a new condition with the blue light off so I was concerned but it seems not to make much difference.

We've seen some posts here about this lately and they may indicate a pattern that there has been a recent glitchy firmware update. Let's check the signal status values just to make sure that things are within specs.

Try getting them here; http://192.168.100.1 

Please copy all of the text in its entirety of the *Downstream Power Levels*, the *SNR's* (Signal to Noise Ratios), and the *Upstream Power Level* numbers and paste them into your next post.

@EG​ just an update, the blue light has returned and seems permanent for now. Speed seems the same.
