I am looking for something similar, but I have one additional requirement. I am looking for something with WDS support and 802.11s support (MeshPoint) along with all of the listed requirements below... I'd also prefer a solution with two antennas for diversity. I believe I cannot use a USB device to host a MP, but if I can, that would be the best answer, since I could simply integrate a USB device. Any recommendations? Thanks in advance.
