I have a D-Link DI-524 Wireless Router and I'm trying to set up the WPA-PSK security on it. I called up tech support for help setting it up, but they said they don't support it, even though it is possible to set it up through the set up screen. All it tells me to type in is the passphrase. How long can it be? Should it be a mix of words and numbers? Is it safer then WEP? I need some help setting it up. ANy help would be appreciated.
