Review on Wi-Fi router ASUS RT-AC66U, black by Doyun Won ᠌

Prior to this router, I used Airport Extreme, but I "rukazhop" and put it where the heating pipes. The station lived an honest 2 years and died. The total area covered by the station is about 250 sq. M, 3 floors house. Everything about her suited her, there was never a situation that he hung. Then, the station died and I faced a choice: Try another brand or buy new Extreme bollards from Apple. Unfortunately, the directional beam technology (really, really wanted) for Apple technology is only available on American Extreme, and the router was needed here and now. Not finding it, I bought this miracle (at that time it was 2022 cheaper than Extreme). I took it according to the principle = maximum rating from reviews + high transmitter power (3 floors as be) + expensive. That is, I consciously understood that I would have to pay more because of the power and performance. The 7th month of use has gone, or better to say directly - the bullying of the company Eysus. In the house there are from 3 to 16 permanent devices (including the Apple-Tv set-top box, Samsung TV, etc.). 1. If you sit at the laptop, then periodically 2-3 times a day the Internet disappears for 4-8 seconds. Moreover, it disappears on all devices (in fact, this problem made me write a review. I found many similar complaints on the forums. And as it became clear later, there is no point in messing around with different firmware). 2. I use SIP-telephony, and also use messengers a la Viber, Skype and WhatsApp. At first I was surprised that during active work (many devices or downloading a torrent), almost all calls are cancelled, especially when the speed is almost the maximum that the provider gives (100Mbps). Before that, on Apple Extreme, I didn’t have this at all. Then I got to the QoS settings. Oh my God! While I found the ports of all messengers, configured everything - an hour left. And so, I sat down and thought - you can live with small "falls off", and QoS will correct the situation with calls. No, the situation did not improve, but it began to hang for a few seconds more often. Curtain!
