You can read that support is limited by a recent reply at the next link.
If you are getting this message just launching the browser, I'm sure Samsung will fix that. Unless that home page is a bad site or you didn't login to the hub or there is no network connection (there must be a list of causes like that somewhere.)
Above all, these are not replacing your laptop/PC web browser. Some folk think it would.
I purchased the 46 inch Samsung UN46ES6820FXZC 3D Smart TV in Edmonton, Canada (purchased in Futureshop). My current firmware is uptodate for this TV (its 001016).
There are 2 main issues for me:
I brought this TV only so that I could use the browser. However, within a couple of minutes, the browser crashes with the following message "Your last browser session ended unexpectedly. Restore last session? Or go to home page?". There are 2 buttons labelled "Restore last session" and "Go to home page" to perform 1 of the 2 options. I thought bandwidth could be the issue since Samsung recommends 10 Mbps. But I currently have 20 Mbps connection and have been consistently getting between 16-17 Mbps. Also, when the Futureshop salesperson told me to check a couple of TVs in the showroom assuming my TV was defective, all of them had the same error message coming up on launching the Web Browser. (I checked 3 TVs).
2) When using Samsung AllShare, I get the error message "Device disconnected: Device name <<displays my device name>>".
The workaround is to connect a Laptop to the TV and use HDMI. But then this defeats the very purpose of a SMART TV. Can soome, especially a Samsung rep, give me information. I would have attached a scanned copy of the error message but there is no such option to do so.
