Netgear WiFi: 2 different routers

I have have Netgear WNAP320 Access points and F728TP managed switch.

I want to set up 2 WiFi internet connections one Guest and one Internal. I have set the internal to VLAN 1 and it works. I have set the Guest to VLAN 20 and I can authenticate but don't get an IP/Internet connection.

The Guest router is on range and internal we are on 192.9.100 range.
Port 1: Local network switch/Internet.
Port 2: Draytek Router (Guest Internet
Port 3: WNAP320 Access point.

The AP's port (3) needs to be tagged in VLAN 20 also.

I tagged port 3 as in the image below. When I try connect it just says 'Obtaining IP Address'Vlan 20
Craig BeckCommented:
You've not actually 'tagged' the interface in VLAN20, you've untagged it.

The port needs to show a T in the box... T for Tagged, U for Untagged.
