|Here's what worked for me.|
From the samsung troubleshooting website: http://support-us.samsung.com/cyber...
"26 character WEP keys are not supported by our Blu-ray Players. If you are using a 26 character WEP key you will need to change your password or use WPA encryption on your network."
WEP security was working before , but then had the Gateway Ping issue when I changed my WEP key. So after reading the paragraph above, i changed my router encryption to WPA2-PSK (AES) and reset the samsung unit by pressing/holding the stop button on the unit for 5 seconds. Did the setup and it worked like a champ.
