@David-TP The version 1.6.2 ( AP MODE ) is the last descent version. The 1.6.3 and 1.6.4 have performance degradation. TP-link need be more carefully with this firmware versions.

@mrcoco I'm not brave enough to update a two-day old version of tplink. I do not trust. I'll wait a while before updating

@mrcoco where you download this version?

@RodrigoBR

@David-TP 3 decos set as access point. 7-8 Clients all day.

@David-TP I have 3 in the m9 plus and all configured as Ac. no1 connects to no2 by cable and no3 connects to no2 by wi-fi. all version 2 with firmware 1.6.1. every day I have to restart the nodes...
