Hello! I have been running Debian 8 64-bit xfce. Networking works fine. Then I added openbox. So now at the desktop manager screen I can choose between xfce and openbox. Networking still works fine using xfce (network-manager).
But if I start up into openbox, or startup into xfce and then log out and into openbox, although I can ping localhost, I can't seen to connect to the outside world using Firefox. (Which makes it hard to fix the problem!). But if I log out of openbox and back into xfce, networking again is fine, and I can connect to the outside world. So, how can I get openbox to communicate with the outside world? Note: the openbox install was extremely minimal, the menu only added Firefox and a terminal. I manually added obconf, obmenu, and feh, per the openbox article in the Debian wiki.
