So for anyone using testing image antergos-2014.05.07-i686.iso the current Xfce install fails to load gvfs-smb for network browsing support for thunar.
If you are having an issue with browsing the network that is the main cause.
You can open Applications Menu > Accessories > PacmanXG (enter password if sudo) search for gvfs-smb
Open Applications Menu > Terminal Emulator then type:
sudo pacman -S extra/gvfs-smb
Simple easy and your on your way.
Please let me know if this helps.
Have an Awesome Archie Day
