This logs to scan2ghz-01.csv. Similarly, run a second instance for 5 GHz. The CSV includes BSSID, ESSID, channel, power, #data, etc., and is updated every 5 seconds by default (tweak with --write-interval). We can't run two airodump processes on the same radio. Each should have its own dedicated adapter - one for 2.4 GHz and one for 5 GHz. This logs to scan2ghz-01.csv. Similarly, run a second instance for 5g.

To cover the full Wi-Fi spectrum efficiently, we leverage two adapters simultaneously. Though airodump-ng supports multiple interfaces in one command, using separate instances simplifies control.

Both airodump processes can run in parallel, each scanning its own band. Just ensure different -w output prefixes to avoid file conflicts. If desired, you can run both interfaces with one command and control behavior with --cswitch, but separate processes are easier. Check that each instance is hopping through its channels (1-11 and 36+). If the 5 GHz scan shows no results initially, it may be due to current channel inactivity.

Dual-band APs with same SSID but different BSSIDs will show twice - expected. Use BSSID for deduplication internally. End-user output can omit BSSID :) Dual-band APs with same SSID but different BSSIDs will show twice - expected. Use BSSID for deduplication internally. End-user output can omit BSSID :)
