I have this problem when my macbook air sometimes does not connect to free wifi hotspots. When the problem happens and I try to run the diagnostics, it normally gets to yellow network settings tab. It seems that it for some reason does not acquire automatically the router or dns address. Sometimes after I shut it down and restart it magically connects to the wifi hotspot but it is very inconsistent. Anyone knows a fix for this problem?
