For several years I lived with a wire from the router to the next room. Speed ~90 Mb/s. Tired of the wire on the floor, took without looking TP-LINK TL-WN851ND. This is a card with 2 n and 2.4GHz antennas. I was horrified - the speed is 1Mb / s. Well, the price is right. Bought this device. I did not install firewood from the disk - I downloaded fresh ones right away. First, I put the horns on the system unit under the table. Speed at 5GHz - 30 Mb / s. Raised the horns on the table - go nuts, the speed has risen to 90 Mb / s. Only half a meter - and what's the difference. The beast. I would take it even further, but the wire is short.
