Here is a spectral history screenshot from a RB951Ui. As you can se, there is a -60dbm (yellow) narrow band signal at about 2462MHz.
So, this signal isn't a real radio source.
The router created it by own; in fact I cannot see anything with a spectrum analizer instrument.
If I put this router in another environnement (other town), I always see this auto-generated signal at 2462MHz in spectral history and spectral scan.
Routeros version 6.42.6 .
Anyone have ever seen something similar?
Thanks
