@Solla-topee Now not same the problem, now lose the signal(?), connectivity every 15-20 sec. Dont need manually reconnect, because the signal is on max, but if i test the speed i see its drop...

Tp-link archer t3u plus lose connectivity every 3 sec, weird because the signal is on max. W10 64. I try other drivers but nothing worked, one is worse than the other.
