comment OS X status bar wifi icon - meaning of bars?
Your scaling doesn't agree with what I'm seeing - right now I have all 4 bars (as usual) but Option-click tells me the RSSI is -68, and WIFI Diagnostics says noise is -88, but Quality is Good to Excellent, when it really isn't!

comment OS X status bar wifi icon - meaning of bars?
I think I have 2 problems - firstly the wifi signal from the AP to me isn't brilliant; secondly the bandwidth from the AP to the "internet" isn't brilliant either. But with all this against me, why does the wifi icon still show 4 "bars" implying that everything is as good as it possibly can be?

Thanks, but this doesn't really answer my question "what does 4 lines on the wifi icon actually mean?". I suppose my fundamental question is what is the scale for the wifi "bars".

Thanks, but this doesn't really answer my question "what does 4 lines on the wifi icon actually mean?" I understand that -70dBm RSSI isn't that good, and that -90dBm noise isn't so bad, and that they combine to give an SNR around 15-25 which isn't so great either, but my fundamental question is what is the scale for the wifi "bars".
