Found this to be a useful resource.
A few months back I purchased an '09 Samsung LCD TV and a Blu-ray player, BD 1600. I just purchased the Wireless LAN adapter for either the tv or blue-ray. When plugged into the new tv, it detects my home network just fine, but only detects my SSID on my blu-ray!!! Even though I have good signal strength detected on the blu-ray, it will not connect to the network. If I disable my 128-bit WEP key, then it connects with network. I am not going to leave my wireless network unencrypted! What is Samsung thinking? Leave an open access point on my network just so I can wirelessly stream Net Flix?
I have spent countless hours on the phone with Samsung and they are not helpful. They keep on telling me it is the problem on the people who make my router: Netgear. They also have me power cycle, turn off firewall and nothing works. I keep on reminding them the wireless connection to the tv works!!! They are saying it is my router and my router settings! It is not my settings in my router or the tv would not have connected wirelessly! This is maddening! I just spent $80 on a proprietary wireless device and since tech support at Samsung is not helpful, I will never buy another Samsung product again! Help anyone out there? Thank you in advance.
