Description of problem: I noticed that wifi connection power indicator icon indicates zero power but when you open the list of wifi networks you see the real power level.

confirmed, on my fedora 17 x86_64 that was running kde-4.8.3 (now 4.8.90).
What signal strength does nm-tool report for your connection? My guess is that the atheros driver is not reporting the correct signal strength and the systray icon is doing right and the list is the one reporting the wrong signal.

Which Plasma NM version do you use?
kde-plasma-networkmanagement-0.9.0.2-1.fc17.x86_64 here. I suspect we may have a kernel/driver issue on our hands, since upgrading kernel-3.4.0-1.fc17.x86_64 -> kernel-3.4.2-4.fc17.x86_64 I haven't seen this any more (yet). *crosses fingers* For example, the output from nm-tool prior seemed to be much lower than expected, now seems to be back to normal: foo: Infra, ..., Freq 5180 MHz, Rate 54 Mb/s, Strength 88 WPA WPA2 when before my sitting here right next to it said 'Stength 20'
Hrm, seems some applets/dataengines updates seem to be getting lost after a suspend->resume cycle. I just noticed signal strength works fine until i do that, and similarly the battery applet gets stuck too (see bug #287952)
Well, I do not have problems with suspend/resume. The battery widget reports the correct charge level if I suspend/resume my notebook.
The problem is no longer happening with newer updates, can I close the bugreport?
It's (still) valid for me, but I'll be happy to open a new/different bug (the causes may have been different)
Reopening since it is going to happen again on KDE 4.9.2
What do you mean by "it is going to happen"? Are you planing to deliberately reintroduce this bug?!! Or the bug reappeared? If so can you create a screencast to show it?
I think he means it is happening again (which matches his downstream comment @ https://bugzilla.redhat.com/show_bug.cgi?id=832153#c2 ).

What plasma theme are you using?
Oxygen
I am currentely in a latin-american conference (Latinoware) and here I can reproduce this problem. The odd part is that iwconfig shows my wifi card is not associated even tough I am connected to the Internet (and sending this comment). The systray icon not showing signal is probably due to a driver problem. The fact that the progress bar in besides the connection icon is showing signal is probably a bug.
When you show the wifi card details, does it also show the wifi channel? Here it does not show it.
(In reply to comment #23) > When you show the wifi card details, does it also show the wifi channel? > Here it does not show it. No man, it does not show the wifi channel
So it looks like the same problem I have. Since the problem also affects iwconfig it is probably a problem in the device driver or in another part of the wireless stack in the kernel. Can you confirm that it also affects iwconfig command?
While I am connected to a wireless connection.... [caterpillar@Portatile ~]$ iwconfig wlan0 IEEE 802.11abg ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off virbr0-nic no wireless extensions. lo no wireless extensions. virbr0 no wireless extensions. eth0 no wireless extensions.
Ok, this really looks like an upstream issue (driver issue). Closing the bug.
