i have a microtik doing voucher autentication
and a facebook wifi router doing checkin

i want to use both, but is possible ?

With differen SSIDs - YES.

But the client hás to enter om Facebook check in and voucher or voucher First só Facebook check in aftwr... Its possible ?

Yes it's possible to, but with some external server with dedicated soft.
Simple version - you can redirect user after login with voucher on page with FB checkin

simple redirect to url that appears on facebook url checking ?
but facebook checkin url only appear when the client use the guest network(Wireless) that deliver this option of facebook checkin


i have to try :S
