hm.. strange. I just started messing with r5 and it seems that wifi is not work. It disbles itself after few seconds.. even if i set wifi on in options, it will auto-turn-off in a little while. Whats going on?
btw. i didnt tested previous [r1-r4] versions..
btw. v2 there's some info in the background terminal debug while loading andoroid that "wifi is not whitelisted" [ore something similiar]
have u tried using driver posted here?
