Bug Description
I suspect this is a bug in the kernel. Bug report initated from http://
There seems to be a problem for nm to interpret the signal strength of my NIC (which is a zydas chipset). Interestingly enough, iwconfig reports the signal strength correctly, but nm-applet shows all the networks at 100%.
I will attach a screenshot that explains a lot better than I do.
Steps to reproduce:
plug in a zydas-based network card
Actual results:
100% signal quality displayed on all networks
Expected results:
see 100% for 380 and 76% for "default"

note: this also happens on Gutsy Tribe 1
I saw this bug in Gutsy, and in Hardy (kernel 2.6.24, which was actually useless for me due to bug #220013). I use KNetworkManager, not nm-applet, but otherwise was seeing the same thing -- all networks at 100%, though iwconfig says otherwise.
As per the request on #220013, I've installed linux-image-2.6.25 from Intrepid Ibex, which for me has fixed #220013, and this bug too.
