The DI-524's setup is just plain lousy.The interface simply hasn't been tested! If you go through the "Wizard" you can set up a WEP key, but if you do it through the menu, you get a "Key1 can not be empty" error message no matter what you put in the key field(s).Another part of the lousy interface immediately bites you if you try to set up a WEP key. Most wireless cards and routers have a way to set the WEP key from an ASCII string or Hex string or passphrase. Anyone with any sense will want to use a passphrase, so that's the one option the DI-524 does NOT offer. Very lame, very inconvenient, very poorly designed.
