we use the signal reported from 'iw' for some actions
and I can see them beeing inconsistent or maybe even
wrong calculated (strange values are marked)

beside these 3 shots, i can see also values for signal of:
"8" (positive!) and "-126"...
i can see this with different versions of OpenWRT and LEDE
and with ath9k and Mediathek. What can I do for debugging this
better? The connected station is *not* moving.
bye, bastian
