If you use Mac OS X to connect to a wireless-n wifi network DD-WRT check your settings, you may not be connecting at the fastest speed possible. To check: Hold down option and click the wireless icon in the toolbar. If you see "PHY Mode: 802.11n" then you are good. Now for the rest of us: From the router website go to "Wireless" then to the "Wireless Security" tab and make sure you have these settings. Security Mode = WPA2 Personal WPA Algorithms = AES If you change those settings you should be able to reconnect as 802.11n.
