NAT/Smart Home Device Support
I currently have a ER7206 router at the core of my Omada & smart home setup. I've experienced a number of issues, including very long latency for devices to respond, and random devices disconnecting and needing to be reconfigured to the Wifi. WiFi signal is strong throughout, I have 12 ESP's spread out inside and out to blanket everything with 50-60 dbi signal strength. I've researced various Tuya/Smart Life articles that say that the router may not be able to manage this many active devices (there are about 100 smart devices). So, hence my questions;
1) How many devices can the ER7206 provide NAT services for? I know the recomended device count per eap is supposed to max out at ~25... which would mean we should be able to handle ~300 without issues on the Wifi side if evenly distributed. But what about the router?
2) Are there published specs (I couldn't find anything) that talk about device counts? What about the ER8411 and ER7212 device count support?
3) Could there be something else that is causing the massive latency when controlling the devices on WiFi vs Cellular? I've enabled MDNS, and Cellular control is almost instant, whereas WiFi could take 10-20 seconds, or not work at all, even when the internet speed checks at >100 Mbps.
Any suggestions on where to investigate, what the recomended device counts are for the various router models are would be appreciated.
