I have 2 Harmony Smart Hub's in my home. The goal of them is to interface with the universal remote control, but you can also control your TV devices from your phone via Wifi. There is also an API that my home integrations can use to see what devices have been started/stopped. Since moving to the EAP devices (2x EAP245's and 1x EAP225-Outdoor), these devices haven't reliably stayed connected. I have all of the "advanced features" enabled, fast roaming, band steering, Dual Band 11k Report, Force Disassociation and Airtime Fairness. These devices are connected as "11ng (2.4 GHz)" when they do connect. I've tried creating separate 2.4ghz SSID's (forced 20MHz width as I noticed another post said not to do 20/40 for legacy devices) on each of my EAP's (placeholder SSID created under global wireless config and over-written with individual SSID's on each EAP config) and tried forcing the Harmony devices to use a single EAP with this overridden SSID. When I do this, I still get the devices disconnecting on a regular basis.
I'm attempting to turn off the "advanced features" to see if that fixes the problem. I'm assuming it will because that is the first thing support tells everyone. I assume these devices don't support the advanced features, but disabling the advanced features - which are global settings, impact the whole mesh. What is the best way to get these devices to reliably stay connect, while also making use of the advanced features - which were the whole reason I bought these. I didn't have the same issues with my previous Airport Extreme devices, however there was no seamless roaming or band steering.
I've been testing and it appears that turning off fast roaming fixes the issue. That being said, I also have other systems that experience similar issues (loss of ping every few minutes) with fast roaming on - mainly raspberry pi devices. Any tips on how to take advantage of fast roaming while keeping all my devices online? I was hoping my over-written SSID that goes to specific EAP's would do the trick, but it doesn't.
Here are the devices: https://www.amazon.com/dp/B01M73XY24
it also looks like other Tp-link products have had similar issues, but these appear to be related to the "mesh" products, and as a note, I have mesh disabled. https://community.tp-link.com/en/home/forum/topic/158559?page=2
