What hardware/model can be used to extend a network and support multiple VLANs via wireless, my current setup looks something like this:

I already have the layer 2 switches and router just need the access point to make the wireless bridge, I tried already with Ubiquiti but it didn't work.

Basically, I want to have a layer 2 switch connected to the main network via wireless,  so that the computers connected to the switch can use the LAN and the VLANs, a powerline works but I am getting < 300mbps, with normal basic AP I get ~ 2.5GB but I only see the LAN not VLANS, and in my case I need both.

Any advice on what equipment would support this scenario?
