A:AnswerYes it can be wall mounted. Best Buy was able to supply an in-stock mount we could use.
We don't have unlimited WIFI where we live so we're not hooked up to it - I would check with BB to see what you need to do to get utube 3.
It was in stock.
It is black.
We used a sound bar and then wired it into our home's sound system.
A:AnswerThe TV has a built in browser that is actually pretty good for most web sites and services, but not quite like the Chrome or FireFox apps that can be installed on many devices. All browsers work much better if you connect a usb mouse or keyboard, which is a great addition to browsing!
A:AnswerThe speakers are facing down and it's not the most impressive sound , it is crystal clear , but need a little more power on the bass
I will recommend a sound bar that can improve the bass

A:AnswerAccording to the datasheet from Samsung, it comes with an 802.11AC card so it should be 5 GHz compatible. Check the third page on the link below.
Maybe the first productions only came with 2.4 GHz but then they upgraded it, not sure.
