I'm currently failing to set up a WiFi uplink with an IAP-325. After some while I noticed this hint in the documentation:
The Wi-Fi uplink is supported on all the IAP models, except for the 802.11ac AP models (IAP-2xx Series access points). However only the master IAP uses this uplink. The Wi-Fi allows uplink to open, PSK-CCMP, and PSK-TKIP SSIDs.
What does this mean for the IAP-325? Does it support WiFi uplink?
