Arris SB8200 Suddenly Has All Green Lights

I have an Arris SB8200 modem.  Suddenly today the modem has all green lights.  The downstream light normally is blue. I assume this means that DOCSIS 3.1 is not working.  I logged into the modem and all the channels are unlocked.  Has anyone else experienced this?  The internet is working fine.  It's just the colors on the modem.  My son is working from home so haven't had a chance to reboot yet.

Please post (copy and paste) the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

Everything is good / in spec. Is the color still green ? Have you had the opportunity to power cycle the modem yet ?

Thanks for your analysis.  I can't power cycle the modem until my son finishes his work from home day at 5:00.  I will do that straight away after he finishes.
