Why there is no “wireless” menu option in WinBox for RB 1100AHx2? How can I get that option?
this device has no wireless functionality
No. I am Talking about “wirless” options on the left hand side of the menu.

To use CAPsMAN, you must install the wireless-cm2 package.

I know I have to install that package, but what about that “wireless” option button?
Wireless option menu will only appear after installed the wireless-cm2 package
Well I installed the package and reboot the router but didn’t get the option 
Are you using the latest version of Winbox?
Yes. I had to enable the package first and then reboot. Now It’s worked 
Thanks. Now it worked.
