Strange behaviour with wireless N adapter and corner reflector antenna
Bought a Mini 150Mbps USB WiFi Wireless Adapter 150M USB LAN Card 802.11n/g/b with 2 dBI Antenna.
This uses the Realtek RT5370 chipset.
I already was using an RT8187L USB with antenna in the back room and I swapped over to the new USB adapter to see how it performed in comparison.
I must say the performance was very impressive, equal to or even slightly more sensitive than the previous Realtek.
So I then played around trying various antennas on the new adapter - dipol, yagi, biquad, patch etc and all performed as per expectations until I attached my corner reflector (dipole based).
Performance was shot to pieces. Signal strength was excellent but quality was almost zero.
I double checked the connection. It's using "G" as I don't have an "N" router.
Is this some sort of modulation issue ?
Any idea Why the huge drop in performance ?

Ps here's the unit, which at $5 AU is amazing value. Quite well made too.
