Looking at the ifconfig source it would also appear that it (whatever it is) could also be expressed as a percentage? $ ifconfig ural0 .. ieee80211: nwid unet chan 6 bssid 00:0f:3d:0d:eb:ac 20dB nwkey 0x8353c823e7 100dBm it is the received single strength indicator. take you laptop, move a bit around, go to the next room and you will see that this value increases and decreases. reyk

I'm trying to get a small gui wifi monitor working so can i safely assume that 20dB is maximum? When does it show as a percentage, anyway? --- Lars Hansson

I thought it was the transmit power. the 100dBm is the transmit power. the 20dB rssi should appear as a percentage as well, but some bits are missing in the driver. reyk
