I have looked (without luck) for information about the antenna selection options within the wireless configuration page. I have an external high(er) gain antenna. I was told by the vendor that the antenna has to be connected to the left port (looking from the rear) as the WAP uses this port for RX and TX, and the other port is only used for one (RX or TX, I cannot remember). I have been trying to find the best setting for the device, but Linksys says that using the external antenna (if unpowered, which mine is unpowered) will not void the warranty, but is unsupported, and good luck. I would appreciate any help.
