John,
I have a bird wattmeter as well, while it works great on 2 way radio
equipment that has a constant TX (holding down mic key) it would not work so
well for WIFI because the radio would not be in a constant TX as it would be
switching back and forth between TX and RX. You would be better

We sent an installer out to repair a faulty AP. I told him to use the

As much as I love Mikrotik they do not have Snort. It is a very valuable tool.
That said, you can do like i do and run Snort on a dedicated ethernet port on
