Wallpiercer... an app for remote operation... at 2.4 and a total distance of 10m outside the house, 30mbps... throughout the house of 130sqm, over 80mbps.. 8 devices constantly connected without any issues.. what else can one ask for... if you place it in a central point of the house, you don't need mesh

It has good range and minimal losses!
I installed it in the basement and it reaches 42Mbps from the 47Mbps that the router provides on the ground floor (speedtest by Ookla).
Note: The two floors communicate through an internal staircase.
For those who are interested, the company provides 4x6dbi antennas. They are among the most powerful antennas for routers.

Update 08/2022 - The pirate (with owner's consent):
I took it to my vacation home and used it as a repeater from the beach bar at a distance of 300-350 meters with a building in between! I had signal, it was stable, and the speed was not bad. At the beach bar, I got 15Mbps download speed, while at home it was 9Mbps. I was satisfied because I consider the distance to be large.
Side note: I had it placed on the window glass and had the awning raised to minimize obstacles as much as possible.
Conclusion: Even the awning plays a role in the Tenda's signal :-) (maybe not).

Simply excellent! I got it for an access point and it does its job more than enough! Fast with an easy menu, no crashes and with very good range!! For 29 euros, it's simply value for money!
