Recently I found that there is no check for the maximum size of the WPA2 Shared Key (Wireless > Wireless Security). This is 63 characters. You can insert more characters and Save/Apply Changes, with the result that no connection is possible, even if both sides have the same oversized Shared Key. No warning is given.

Firmware: DD-WRT v24-sp2 (07/21/09)
