Yesterday I installed a Vanilla Raspbian image on BerryBoot to test out Stretch and then go back to my Jessie image.
It all went quite well until I removed it and the Pi said it could no longer connect to the Router.
After looking around the Router I removed everything related to the Pi's local IP (192.168.178.26) and the Pi got back onto the network but weirdly enough no machine can receive or connect to it, not even a simple ping as if the Pi is not connected.
It works fine over LAN but in my situation its not able to receive a constant LAN connection.
Since then I have reinstalled BerryBoot and reconfigured the Network.
This is quite a weird issue and everything I tried couldn't fix it. How do I solve this problem?
