On the latest build of Retropie when I configure the wifi it goes to a blue screen to configure the wifi. which is not bad.
On my other Raspberry Pi 2 it goes to wicd manager which handles the connecting.
But what I like about this you can configure which wifi network is at what range and you can select if it needs to be autoconnected or not and it saves passwords from previous networks.
THIS is what I miss in the new build.
If I bring my rpi2 with me to another friend and he has a difficult password then it’s pretty much a head ache to configure it every single time.
