Orbi RBK23 Router solid magenta

Hmm, I've considered this possibility, but here's where I hesitate: It's been running fine for 4 years in this configuration. The ring on the main node is solid magenta which does not correspond to anything in the KB article, unfortunately, other than for a satellite node, but those are all registering as normal. Lastly, I'm not using the WAN port on the Orbi as it is in AP mode. The only significant change to the environment in recent months is the Orbi firmware update a week or so ago. Regardless, I'll look through my PFSense logs and see if there's anything to see there. I do see 3 errors streaming in the Orbi logs. It looks like there are 3 MAC addresses being rejected for WLAN access. I presume they are devices I have yet to reconfigure since I changed the wifi password.
