How to get networkmanager to connect wifi in bootup.
 

Running CentOS 5.5. NetworkManager is able to connect to wifi after logging in as root in the GUI and entering password to unlock keyring.
What do I need the change to get NetworkManager to connect the wifi at bootup?

I assume you mean Gnome network manager.

This might help.

I gave up on network manager and moved all my wireless computers to wicd. Faster and more reliable.

Edit:

I don't know that you can get either of them to connect on boot-up, as opposed to log in. To do that, I think you have to use /etc/rc.wireless.

I ended up disabling NetworkManager (chkconfig NetworkManager off, service Networkmanager stop), enabling wpa_supplicant (chkconfig wpa_supplicant on, service start wpa_supplicant) and adding /sbin/dhclient eth1 to /erc/rc.d/rc.local. /etc/wpa_supplicant/wpa_supplicant.conf must have the psk set with the result from wpa_passphrase.
