I just reopened the upstream report since it is happening again on KDE 4.9.2
It happens to me as described in Bug 864609 comment 4.
Start wired session in dock station - undock and connect to wifi - first connection gets 0 power - after reconnection it's ok.
I'd guess it could be Wi-Fi driver signal strength reporting issues.
In order to confirm/disprove that, it would help to get/monitor strength NM sees:
$ nmcli dev wifi
or even with iwconfig
What wifi card/driver is that?
$ nmcli -f general dev list iface wlan0
# LANG=C nmcli dev wifi
SSID BSSID MODE FREQ RATE SIGNAL SECURITY ACTIVE
'xxx' 20:2B: Infrastructure 2447 MHz 54 MB/s 65 WPA2 no
'xxxxxxxxxxx' 80:B6: Infrastructure 2422 MHz 54 MB/s 25 WPA no
'xxxxx' 54:E6: Infrastructure 2437 MHz 54 MB/s 25 WPA no
'xxxxx' CC:5D: Infrastructure 2472 MHz 54 MB/s 22 WPA2 no
'xxxx' 00:19: Infrastructure 2442 MHz 54 MB/s 20 WPA2 no
'xxxxxxxxx' C8:3A: Infrastructure 2437 MHz 54 MB/s 15 WPA no
'MOJE WIFI' 94:0C: Infrastructure 2412 MHz 54 MB/s 85 WPA2 yes
So I guess 85 Quality should qualify more then 1 blue stripe ;)
I remind I'm not using Gnome3 shell - I used 2D version.
# LANG=C nmcli -f general dev list iface wlan0

Unsure why VENDOR is garbage string...
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '17'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 17's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 17 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged change the
'version' to a later Fedora version prior to Fedora 17's end of life.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
