Upgrading RB411 license

Hi guys
I just bought a 411 board and I need to upgrade the license on it to Level 4 so it can support AP.
I’ve tried uploading onto my Mikrotik account for upgrading but it keeps telling that it already has full feature.
Please I need to upgrade it.
What do I do?

There are no license upgrades other than to add custom frequency support. You have to buy a new license if you want to move from Level 3 to Level 4 on the RB411. Or else buy a RB411A or RB411AH which comes with Level 4 license and more RAM.

Do you now how can I upgrade my licences to extra chanells at mikrotik.com?

I have many devices from many sources (resellers).

you need to apply for this feature in mikrotik support.
