Hi there, I am a newbie in MT, my question is: How can i enable an interface (wlan1), under interface>print it shows ether1 enabled, but wlan1 disabled (x), please help me to enable the wlan1
‘interface enable wlan1’ or ‘interface wireless enable wlan1’.
I suggest you to start from MikroTik RouterOS documenation, that contains a lot of useful information,
http://www.mikrotik.com/testdocs/ros/2.9/
/interface print
give a look on the id of your wlan1, it’s on the first column on the left, then, if your wlan1 had a “1” id, give on the CLI:
/interface set 1 disabled=no
Hint:
when you press the key “?”, a menu appears with all the possible functions to use on the context which you are.
well thnx, it`s ok now, i have enabled it, my next question is, from wlan1 I am getting the signal (internet) from my ISP, i have ether1 to, so i want to do something like that, accepting the signal with wlan1 from my ISP and transmitting it from ether1 to my clients, I read the manual about this but not understood how to do this, please help me if u want ??? 
You have to make a new bridge, and then add the wlan1 and the ethernet to it. The IP address have to be configured on the bridge, not on the eth1 nor wlan1.
