Ok...
How is your provider giving you ip address? through DHCP?..if this would be your option, you would have to configure into your wireless or ethernet interface a DHCP CLIENT like this
/ip dhcp-client add interface=ether2
If you have to provide statically an ip address this should be your configuration
/ip address add address=192.168.1.244/24 interface=ether2
After this you would have to creat an static route to route all the traffic to your gateway
/ip route add gateway=192.168.1.245
then you would have to setup your DNS
/ip dns set servers=8.8.8.8
I am taking the google dns for this example
try with either one of those configuration and from the router New Terminal ping
http://www.mikrotik.com and see if that resolves
check that out and first get connectivity inside your router and then we will procceed with the rest of it
