Signal strength was -67 dBm with a homemade biquad antenna for a distance of 50 meters from another house (router under the table, adapter on the window), and -59 dBm with a Chinese Mediatek MT7601U purchased from aliexpress for $3 (but the Chinese usb connector was loose and it fell off frequently). This one costs three times as much and is inferior. When the rating was changed from 2 to 3, the signal was really poor, yet he lived for about six months and two Chinese with Ali, whose signal was extremely good, were already dead.
