Hi, I'm having trouble to understand what you need to do and where are you rigth now?
Here are some questions in order to understan
1.- Is the router the Internet gateway?
1.1.- In case it is. Do you have a default route to the router IP?
2.- Which vlan you want to hace Internet access?
3.- What is the systemp IP of the controller?
3.1.- If the vlan 11 is not your system IP you will need to use the source command to ping the router
