I have gone through all the troubleshooting I can on this. Once set up, I scan the site to see my network, the DAP1522 sees it. I click connect, but it doesn't even though the password and settings are correct. I am using WPA2 encryption. Why doesn't this work as advertised?
I, too, am using the 1522 with an AEBS, but without any problems. The AEBS is a MB053LL/A (A1143), which is two models ago and has one radio (either 2.4 or 5.x). The AEBS is running 11n only at 5GHz and WPA2 Personal.
Note: I couldn't connect the 1522 until I turned off hiding the AEBS SSID; i.e., broadcast the SSID. Once the 1522 was connected, I re-hid the AEBS SSID. However, after a power outage, the 1522 couldn't find the AEBS, so I've left the AEBS SSID unhidden.
Here's is my 1522 settings (I didn't show my MAC or SSID):
Wireless Radio : Enabled
Status : connected
MAC Address : ********
Network Name(SSID) : ******
Channel : 149
Security Type : WPA-Auto- Personal / Auto
Wi-Fi Protected Setup : Disabled / Configured
Hope this helps. Let me know if you need more info.
