@paja / @Pepe Please update wifi utilities:
- wpad / hostapd packages: upstream available wpad is version 2018-05-21-62566bc2-5 whereas the TO has only version 2016-12-19-8 available.
- Implemention of patches to hostapd and mac80211 are needed to support 160MHz width channels as well as DFS scanning for it. See this topic for more information. @Jan.H stated in this thread that the Turris team has WLE1216V5-20 cards available and tested them, so I assume you also looked for getting wave2 up and running in its completeness.
