Very mixed

At one site the terminal works very well. At the second site, you have to reboot the terminals every day. It nevertheless has a facility in any TP-Link, we are not isolated and are picking other wireless network, so no special interference. The TP-Link support has been totally useless on the problem analysis, efficiency is almost zero.
Key point to note: the scope is important - I tested large antennas, it does not change much in the end, the original ones are highly efficient.

On my first site I will put 5 stars: it works well. On my second site 1 star: it's not working. I am therefore an average of 3, and I order a D-Link DAP-2690 to replace those that are problematic.
