Mit Hilfe dieser Datei kann man das Hintergrundrauschen ermittel und somit auf allfällige Störquellen reagieren.
Hier nun ein Beispiel:
cat /proc/net/wireless Inter-| sta-| Quality | Discarded packets | Missed | WE face | tus | link level noise | nwid crypt frag retry misc | beacon | 22 wlp3s0: 0000 52. -58. -256 0 0 0 45 95 0
Der interessanteste Wert ist noise, je tiefer dieser ist, desto näher ist man der Störquell.
Der andere Wert ist level, dieser gibt die Signalstärke in db aus.
