I thought that there would be a USB port, it turns out that there are 2 different models C-20 and C-20 ru under the same name. The difference is in the USB port and the number of antennas (and in the price, of course). I took it to "isolate myself" from my parents at a frequency of 2.4, and the old 740n tplink has already begun to freeze. As a result, the range of 2.4 GHz doubled - it "beats" from the second floor to the neighboring house, and the speed is not cut due to old devices.
