Review on WiFi router TP-LINK Archer C6U, black by Karen Nahm ᠌

I moved the workplace to another room and kinetic 2 could not provide a good signal through a 40cm concrete wall, it gave out 15-30 Mbps at 2.4G, there is no other one) I started to surf the Internet, looked at kinetics, xiaomi redmi ac2100, tenda ac10u and tp links. Kinetics are expensive, they advise not to take the tendu, I decided not to risk it. Xiaomi scared away with bulky sizes, a Chinese plug and firmware. There are TP links left, there is an archer C6 in use, an excellent router, but it seems to be a bit old (they say in revision V3 the stuffing is like in C6U), so I wanted to find something similar, but newer. As a result, I began to choose between C80 and C6U, I chose the latter because of the more productive stuffing, although it is possible that the C80 has a better signal and MIMO is 3x3 there. So, what am I talking about, now 5G communication gives out all 90 Mbps through this thick concrete wall! The apartment has two PCs, a laptop, a tablet and 2 smartphones, there are no complaints about the operation of the router, I'm satisfied.
