FIX: Doesn't show networks? Try this.

[neko18]

I'm using GTKWifi 1.09 that I downloaded from the SourceForge.net project page and assuming you have the same version installed. When I installed it, none of my available networks showed up in the "Select Network" list.

======================
Remove the GTKWifi applet from the panel by right clicking it and selecting "Remove From Panel"
----
Open a Terminal window
(Applications->Accessories->Terminal)
----
Open the program file in gedit
gksudo gedit /usr/bin/gtkwifi
----
Go to line 62
(Hit Control-I, type `62`, then hit Enter)
----
Change the line to look like this:
self.icon_lock = "/usr/share/icons/gnome/16x16/stock/data/stock_lock.png"
----
Go to line 63
(Hit Control-I, type `63`, then hit Enter)
----
Change the line to look like this:
self.icon_lock_large = "/usr/share/icons/gnome/32x32/stock/data/stock_lock.png"
----
Save the file (File->Save)
----
Close gedit
----
Close the Terminal
----
Right click the panel you would like to place GTKWifi on and select "Add to Panel," scroll down to the "Internet" section, then drag the "Wireless Connection Manager" icon to the position you would like it on the panel
======================

Done!
