Comment 55 for bug 972604

Yes, the wifi led blinks between red and blue, indicating network activity, in place of indicating wifi status. For example, it blinks heavily when loading a web page (it appears purple because of the speed). My workaround relatively because colors are reversed (as described at the top of this report).

Yes, wifi works when led blinks also. Your last test kernel removes the regression (but the original bug exists yet).
