I would need to retrieve the signal strength through hostapd or iw of my Access Point (AP) device which I am using with Linux.
I don't know how to do so through hostapd because the dump_file has been disabled so I can't even check the file for information.
Using iw I get:
~$: iw dev wlan0 station dump Station xx:xx:xx:xx:xx:xx (on wlan0) inactive time: 4190 ms rx bytes: 1380 rx packets: 4 tx bytes: 358 tx packets: 2 tx retries: 0 tx failed: 0 signal: 0 dBm signal avg: -26 dBm tx bitrate: 1.0 MBit/s rx bitrate: 36.0 MBit/s authorized: yes authenticated: yes preamble: short WMM/WME: no MFP: no TDLS peer: no
But I always get signal 0 dBm. Does not matter the distance/location of computer connected to the AP station.
Is there an alternative solution to get signal quality or signal strength ?
