Very disappointing! 30

I expected a very high sensitivity and outstanding performance over the Intel 6945AGN wireless card with a PCIe adapter and 3 tiny antenna I was using before.
In reality, this does nothing more, no improvement, despite its 3 large antennas and I have the same transfer rate less than what I had with Intel 6945AGN with triple antennas 2dBi Hama in ... ^^

I turn therefore to the starting solution, except that I bought in between "the Hama WLAN antenna" Triple "2dBi" for ten Euro, and in the end it works much better! ^^

Still, I do not understand is that with a Wifi USB key down range, I get a transfer rate between 8 and 10 times better than the two PCIe solutions ...

Like what the most expensive solutions are not necessarily the best ...
