Re: how to scan for AP signal with spectrum analyzer
Well if you walk outside the room does it getter stronger or weaker? IS there a Cellualr carrior or any other ISP in the same colocation room as you?
I have not seen a true frequency hopping 5.8 setup only 2.4 You should see the center point as a peak of the freq they are set on and then see weaker signals tapper off to each side of center. It also depends on the width of the freq as to how far on each side from center I.E. if they are using 20mhz channels then you will see the center point and 10mhz to each side usually.
Sounds like there is someone else running 5.7 equipment in your room.
In alignment mode the system is just listening and not actively broadcasting such as in AP bridge mode.
I have not seen a router board that has failed allowing the radio to not work, I am not saying it cant happen I just have not seen it yet. What radio card is it? are you sure you have it set to the correct ant? Is the reading you are getting on the spectrum the channel you are on or is it completely different?
What happens if you unplug or turn off the mikrotik completely does the spectrum go blank or do you still see the signal? If you still see it then I would guess like I said above someone else is in the same room using 5.7.. If this is a true tower site the tower owner should know everyone who is located in that room, what frequencies they are running etc.
