Hello , I had to replace my router etc, and set everything up (SSID ip addresses etc) like it used to be. However, now when I boot a raspberry pi 3b, I get a "IPv6 wlan0 link is not ready." while ipv6 is turned off? (I tried to create a new centos image on an SD, but somehow thatdoesn't work. where is the latest working version of it?) is there a way to fix this wlan0 error ? thanks, Ron
