I've run into that with spaces in the SSID or password. Samsung and other makers are not implementing all that is possible in WiFi and I can't guess your settings or choices.
In the CNET Networking Forum I have a top post with many other gotchas for you.
Just received Samsung BD-E5400 Blu-ray disc player that will not connect to wireless, giving the "cannot support TKIP 802.11n security type" error message.
I called my wireless provider who took me to my wireless set up and confirmed that I was already set up in AES mode, not TKIP. My wireless password is 13 characters long. Please help, or this is going back to the store!
