I have a problem with WAP551 and 2 SSID.
SSID Enterprise = VLAN 1
SSID Visitor = VLAN 110
Enterprise's network sets with an unique network and visitor's network sets with an other network.
I'm sure about my configuration because when I set the SSID enterprise on one WAP and set the second SSID (visitor) on the second WAP, I can reach default gateway's enterprise or default gateway's visitor.
However, when I set two SSID on the same WAP, one of the two SSID can't reach my default gateway. On my laptot, I got this message No internet access.
