hi,

I have two netmetal5 device. I want to ask you a few questions
I want to run around my house in AP
There are 2 antenna input, but no antenna, is without antenna works
Only 5 GHz support works with the devices, did not receive any broadcast device. How to simply configure
Thank you.

first, don't power them without an attached antenna. You can destroy the final radio power stage.
Second, you need a pair of antennas to connect them.

Or you could just return them and get SXT series instead, which already have integrated antennas.
