It will be enough for the TV in any case, probably also for your office. The 2400Mbits/s are rarely reached. With short direct power lines, it may be close. But even in the office, there will probably be enough speed to be able to play online games smoothly. I am satisfied with it. It is easy to install and you can change the location at any time. The adapters should always be directly in a socket, not via multiple distributors. The WLAN transmission rate is higher with the Wifi-6 kit. It's up to each person to decide whether the extra charge is worth it. I don't need it.
I bought this product a few weeks ago. It is indeed the Next. This is a translation problem. The "Next" has been translated in the text as "Le prochain".
