@Jonas-Homekit I ended up buying a BE85 and set that as the main unit for my XE75's, with the assumption that more processing power would help... And it definitely has. Still some quirks with IOT...

@Rhyalus Would you say a marketable improvement in stability over .10 or prior?

@ImtiazAli Beamforming has been, for the most part, a nuissance, resulting in greater disconnects and compatibility issues. And that may work for a handful of devices, but we are talking 100+ devices...

Has anyone tested 1.2.11?

This seems to be TPLink's MO. They are spreading themselves way too thin and cannot support all products. :/

@Jonas-Homekit You can download 1.2.10 from the website. That's what I am running on our network right now. But still running into issues.
