I'm addressing this post to
@drinkingbird since, you're the one who's helped me with the issue. Seems like I've had to update my guest network settings for my lights. Initially, if you remember, I created the guest network with intranet access disabled. Well, Wiz updated their lights to support matter, which wasn't working, even if I put the iPhone and Apple TV 4K (home hub) on the same guest network as the bulbs, matter still would not pair, or work. Seems like enabling intranet access in the guest network settings is the only thing that fixed it.
I was concerned doing so, would start the random drop offs again, but, so far it hasn't. I'm still using Guest 1, which has a different subnet from the main network, so that still may be helping it.
As far as the router, and this firmware in general, still been rock solid. The new printer I got even connects to 2.4ghz on the main network without problems, and keeps a solid connection.
For Reference: the printer is model # Epson ET-2800.
So overall happy with the setup. Just thought I would ask about the matter situation to see what your thoughts were since I'm not real familiar with it yet on a technical level, and what it requires from a network to work.
Thanks
