A single-channel bandpass
filter will help most poor-to-middling receivers by protecting
it from overloading from the off-channel signals that the cheap
receiver front-end would otherwise let come barging in,
desensitizing the receiver and reducing the signal-to-noise
ratio.

When I put that puppy in, I got like 40 dB less noise on the channels I didn't want, and I also could not even hear other APs when I moved the radio to channels 2-11 (there is that much isolation in the filter). Now throughput is much smoother and higher. Before I put these in, bandwidth would be slow and come in spurts (as evidenced by various throughput tools like iperf and online speed tests). -- Jack Unger - President, Ask-Wi.Com, Inc.
