i made a few tests
opened again, removed both antennas, and tried both on 1 and 2
when only one antenna doesnt matter wich one, black or white, are connected to 1, i got 5mbps-1mbps speed
and when i connect only one antenna black or white, on 2, i have the same behavior as now with both connected!
adapter problem? how does antenna 1 works anyone can tell me? the purpose of antenna 1?
i hope it´s not an adapter problem
