If you noticed in your DD-WRT Wireless tab that some wirless devices are connected/stuck in legacy mode, one possibilty is the incorrect choice of WPA algorithm being configured for your AP.

Make sure AES is choosen as the WPA algorithm, instead of TKIP (which is the the older encryption protocol introduced for WEP).
