Haven't gotten an update for a year now. Still missing the features like IoT network, VPN and so on that X50 (and the few preffered models) already got.

Don't buy TP-Link.
It's unfair firmware and features rollout policy is abysmal. It doesn't even bother with periodic security fixes.

And X50-4G is no longer showing on the Deco page of the website in my country. Must have quietly been phased out towards End of Life despite being relatively new. A "newer" X10-4G model is being pushed to consumers instead but expect the same issue with firmware and non-existent features parity.
