WE1626 Router, How to configure in AP Mode?

Hi, I've just buy this Product model: MT7620N, of the WE1626 Wifi Router

but I can't find how to change the operation model to make it work as an Access Point..

Can anyone help me? thanks!

If you're running some kind of OEM vendor firmware, please contact their support for advice.
