I am running a version of RHCE6 on my laptop, and lately I've been trying various stuff about network configuration through command line. Last night, I tried removing the NetworkManager using "yum remove NetworkManager" from the system, so that I could have more control of the network through the command line. But the result is, I didn't manage to configure the wireless connection through wpa_supplicant, and I need wireless connection during my travel to another place. So I need the wireless function back as soon as possible. I typed " yum install NetworkManager", some version installed, but I don't get to have an icon on the taskbar, and of course, the network doesn't work. The package I previously removed(about 24MB) was much larger that the one I just installed(about 2MB), so I think some dependencies must be missing. How could I install all these dependencies? Please help!

This question came from our site for professional system and network administrators.
Did you check the Wiki page for NetworkManager
Check if running or Start if not:
Start if it's not running:
Disable network and wpa_supp services as stated in Wiki:
And Reboot. To open it's GUI:
UPDATE 1:Check out Reinstall all dependencies of a given package?
