Hi, I just bought the aforementioned TV brand new yesterday - I set it all up (which included software update) straight away and it connected to my wifi no problems and I watched Netflix all night. 

Today, it can't connect to the wifi. It doesn't even find the router (which is 10 feet away), and the router is not at fault because I am using it right now with my laptop to write this post.

The connectivity test says it finds the onboard wifi, but doesn't find any wifi routers -there are several in range as I live in a block of flats. I tried looking for some help on the Sony support site and it doesn't even acknowledge that this specific model exists - the page has thousands of models listed (shown below), even the models ending with a 0 and a 2, but not my one ending in 1.

How can this TV and Sony support be so sh**? Is this TV simply broken?
