I am trying to get Airodump-ng to keep every AP (WIFi) found. By default airodump-ng removes found BSSID if it doesn't get anymore beacons frame from the AP after 120 sec. I know about the "--berlin" option to set the amount of sec airodump-ng will keep found BSSIDs, but i want it to keep it forever (or until i restart airodump-ng). I have tried to export the scan to a log with " >> scandump.txt", but the log come up blank. Any help would be great, btw this is on a pineapple mkv. thx,
