I. Brief Introduction
TP-LINK Access Point Product such as TL-WA701ND, TL-WA801ND, TL-WA901ND, has a feature called “Multi-SSID”. It can broadcast up to four wireless networks with different names. When using Multi-SSID, users could also assign different VLAN ID to different wireless network. This makes it possible to get TP-LINK AP work with switches which as VLAN assigned for different access level and authority.
Below is a basic topology of How TP-LINK AP should work with Switches that has VLAN assigned. Assume that in the network there are four Departments: HR, Sales, Technical and R&D. They belong to different VLAN networks to have different authorities (HR-VLAN1, Sales-VLAN2, Tech-VLAN3, and R&D-VLAN4). When we setup VLAN to each SSID, for example:
SSID 1 with VID 1;
SSID 2 with VID 2;
SSID 3 with VID 3;
SSID 4 with VID 4;
Then Group A, B, C, D will only have access to its related VLAN resources. Take Group A as an example, the clients are connecting to SSID 1, so these people would only have access to the HR department’s resources. (The Access authority of different VLANs is already configured in the Switch. TP-LINK AP here is to extend this VLAN authority from LAN to WLAN. We just talk about AP settings in this FAQ. )

It’s quite easy to configure this VLAN function for different SSIDs. Below shows you what to do:
1. Connect your TP-LINK AP to your computer with a cable. Manually configure computer’s IP address to be in the same subnet with AP. Then log into Management Page.
2. Go to Wireless->Wireless settings;
Choose Multi-SSID as Operation Mode; Check “Enable VLAN”; then assign VLAN ID for each SSID. When all finished, click Save.

3. Till now, the wireless is still unsecured. Go to Wireless Security and secure each network. Different security type could be used for different SSID.
