I've been trying to configure the Standalone setup of eap110 with this setup below but i can't make it work and why did they remove the ssid isolation in 3.4.0 update?. WIFI SSID1: Guest Wifi Load Bal

After configuring the standalone setup for eap110, i've notice once creating open network with portal enabled a visitor can scan all the devices connected to that open wifi and i think this is not goo

I'm planning to change those built in antenna of EAP110 Outdoor with higher dBi. What outdoor antenna would you recommend to use and the dBi also? Because i can't get enough signal over it.
