I have the same hardware and firmware version, though I'm currently using mine as an AP.
Make certain the wireless settings for the DAP-1360 (SSID, 802.11 Mode, Channel, Channel Width, Security Mode, and Key) are identical to those on your router. Once it looks like the DAP-1360 and router are connected (wirelessly), log into the DAP-1360 again, and go to the Wireless Setup page. Click on the Site Survey button and location the SSID for your router (it helps to know the MAC address for your router, and you may have to scan a couple of times before it shows up). Select the SSID for your router, and click on the Connect button (bottom of pop-up window). Don't forget to Save Settings.
Let me know if that helps,
Larry ....
