If ethernet is connectes, wifi icon also show connected. If I disconnect ethernet, wifi starts looking for networks and shows that exclamation mark on icon. Wifi never gets IP via DHCP. Manually setting IP won't work.
Why didn't you say that the first time.
Did you go into the affect Mac System preferences->Network, Wi-Fi side channel, Advanced button and see if the Preferred Network at you want to connect to is present.

Try removing wifi passwords from keychain and the network from network prefs, restart and then try to connect again.
You go with a developer preview to the Genius Bar? *lol*Never had that problem with my rMBP at home, or any public networks. I would take it to Genius bar if you have already changed wireless channels.
15" rMBP here with no WiFi problems (so far), connected to a 2.4GHz N router.
I only had it drop out once on me yesterday. That's not terrible. I wouldn't care, except I have my iTunes on my NAS, and I don't want to drop the connection while I'm connected as it can corrupt things.
Once a day isn't bad though, so I'm not worried about it. I'm sure it will get fixed soon.
