Review on Wi-Fi adapter TP-LINK TL-WN822N, white by Virot Rongrot ᠌

I bought it a couple of days ago as a pair to the ZyXEL Keenetik Lite II router. The router is in the corridor, it is separated from the computer by two walls, one of which is concrete. Signal level "excellent". Before this adapter, I tried another one (zyxel NWD2205 EE), but on that the signal level constantly "floated" from "excellent" to "average", and wi-fi even fell off several times. I bought this adapter and have not had any problems for several days now. And it costs 2 times cheaper, that's a paradox.
