I did that via Winbox, but when i make a survey an click on "connect", the DHCP client dont show nothing but a "searching" message.
It never gets any IP.
You already said that in your second post and my crystal ball is broken so I can't help you, and probably nobody else until you provide some more information. It's completely impossible to guess what actually cause your problem and nobody has time to do that, because we have our own problem to solve or systems to configure. Do as I said in my previous post, at least provide the log.
