The DAP-1522 works well with the DIR-825, but it can be a PITA to set-up. Although I seldom ever recommend WPS, it was the only way for me to get this combo paired for longer than a few minutes on the 5ghz band. Even when I manually typed in the correct info, it would connect, but I got dropouts for some reason. After the WPS pairing, and some manual manipulation, everything is perfect. I'm running 1.31 fw on the 1522 and 2.03NA fw on the 825. Both devices running stock IPs, 192.168.0.1 for the 825 and 192.168.0.50 for the 1522. DCHP is enabled, but only for 192.168.0.200-254. All of my routine devices are set up on static IPs in the 100's, which has proven to be more stable, especially with my Denon networked AVR. I have a total of 15+ devices that connect on both the 2.4ghz and 5ghz bands, and I have now gone 12 days without a reset or dropped connection.
