Hello all, I would like some advice regarding upgrading the 3 antennas on the RT66N. I have been looking around, and have noticed that I cannot seem to find an after market dual-band antenna. They all seem to be either for one band or the other. My question is, if I buy 3 of these TP-Link-ANT2408CL 8db 2.4GHz antenna, will doing this cause harm to 5GHz coverage? I have to say, I can't imagine that the antennas on the Asus are anything special, and are probably just 3 or 4db gain 2.4GHz antennas that have been thrown in by Asus, and work "good enough" in the 5GHz band. Thanks in advance for any ideas!
