fedora | The Road to Elysium

I just reinstalled one of my machines with Fedora 21. The install went great, but when the machine was done rebooting, and I was trying to set up my access to a wireless network with nmcli (NetworkManager), I got the following error-message:

# nmcli dev
DEVICE   TYPE      STATE        CONNECTION 
enp0s25  ethernet  unavailable  --         
lo       loopback  unmanaged    --         
wlo1     wifi      unmanaged    --

# nmcli dev

DEVICE TYPE STATE CONNECTION

enp0s25 ethernet unavailable --

lo loopback unmanaged --

wlo1 wifi unmanaged --

..and:

# nmcli dev wifi rescan
Error: No Wi-Fi device found.

1 2	# nmcli dev wifi rescan Error: No Wi-Fi device found.

Spending a lot of time finding what the problem was, I finally found the solution. It seems that Wi-Fi support in NetworkManager has been separated to a plugin. The package NetworkManager-wifi was missing. According to Pablo S. Torralba, who was kind enough to comment on this post, it should be enough to kill NetworkManager and launch it again as root. Should that fail, you can always try the old reboot-trick! Either way, it should hopefully be working.

If you’re on Fedora 20, are trying to run wicd-curses, and keep getting errors like the one below:

Traceback (most recent call last):

self.__super.__init__(use_enter=False)

File "/usr/share/wicd/curses/curses_misc.py", line 351, in __init__

self.focus = focus

AttributeError: can't set attribute

..then the fix is simple. Open up the file /usr/share/wicd/curses/curses_misc.py, go to line 360, and paste the following below:

    @property
    def focus(self):
        return self._focus

    @focus.setter
    def focus(self, index):
        self._focus = index

    @focus.deleter
    def focus(self):
        del self._focus

    def set_list(self,list):
        self.list = list

@property

def focus(self):

return self._focus

@focus.setter

def focus(self, index):

self._focus = index

@focus.deleter

def focus(self):

del self._focus

def set_list(self,list):

self.list = list

wicd-curses should be working again. This is currently a bug on Bugzilla (https://bugzilla.redhat.com/show_bug.cgi?id=894646).
