GNOME Bugzilla – Bug 424306
signal strength for zydas devices is stuck at 100%
Last modified: 2007-06-10 23:57:44 UTC
Please describe the problem: 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: Expected results: see 100% for 380 and 76% for "default" Does this happen every time? yes Other information: $ lsusb Bus 003 Device 007: ID 0ace:1211 ZyDAS 802.11b/g USB2 WiFi $ lsmod Module Size Used by zd1211rw 52868 0 $ uname -r 2.6.20-13-generic

This is almost definitely a driver problem with the Zydas driver. Should be filed as a kernel bug against your distro's kernel component. Thanks!
Not sure. How come, as I said, iwconfig reports the signal level correctly? I can only interpret that the driver/kernel is correct but something is wrong with NM no?
iwconfig will report it correctly because that's for the current connection. but 'iwlist <dev> scan' is what is reporting 100% all the time here for you, not iwconfig. Note that even in that screenshot, the "Quality=" lines in the terminal are both 100%. So both NM and iwlist are showing essentially the same quality, meaning that either the driver itself is having problems, or the driver legitimately thinks the connection quality _is_ 100%.
thanks for the explanation :) (and for the record, yes, the two wireless networks were assured to have different signal strengths)
