Sony UWABR100 USB,
This review is from: Sony UWABR100 USB Network Adapter Bringing Wireless Internet Access to Your Wi-Fi Ready TV (Accessory)
extremely overpriced but it does what it says it does, you don't have the choice, you have to buy it otherwise 80% of the TV capabilities are useless without this key. Honestly for what the TV costs, SONY should provide this key as standard, this is a bit abusive in my opinion.
