A:Answer Excellent question, and one I'm still looking for the answer to! After I purchased and was setting up wifi I looked for and could not find the answer. It was important because I had to decide to connect to my 2.4ghz or 5ghz band. No sense in connecting to the 5 if the wifi could only handle N speeds. What I can tell you is that I opted for the 2.4 band and have had no buffering or latency when streaming 4K content, so it may be an irrelevant issue.
BTW: I've thought about connecting to the 5ghz band and doing a network analysis to see at what speed it is connecting, and will update my answer if I find out.
