I've problem with the RB411AR and the builtin 2GHz radiocard. The noicefloor is 10-15dBm lower then
using an r52nM card on the same routerboard, configuration and antenna.
I have tried 4 different RB411AR with the same result. The older RB411Ar with ufl connector is much
better. There it is only a 5dBm difference
I tought I had a lot of noice on my sites, but when I tried in a proven noice free site I started to wonder.
Compared to RB751G-2nD there is almost 20dBm difference in the noice floor. Makes a huge diffenence on the usable
usable distance for the wireless network.
Is the built in card so bad in it's filters or is it a driver issue?
Anyone noticed this as well? Any comments welcome.
