I've got a wireless access point (TP Link TL-WA801ND). The AP has a Multi-SSID mode where the AP will broadcast multiple SSIDs, and optionally VLAN tag the traffic on each of the wireless networks.
The LAN section for that same AP has a single section for setting up IP address and gateway.
If I enable Multi-SSID mode, traffic will then be tagged for a VLAN. However, it appears to me that all traffic still will travel on the same subnet - the one I set up in the LAN section. I can't really get my head around how VLAN separation takes place here.
Even though all traffic from the AP is VLAN tagged, how will this work when - apparently - all traffic still travels on the same subnet?
I do know that I need a switch which supports VLAN tagging, but still - does this change the fact that all traffic apparently will travel on the same subnet?
