http://unix.stackexchange.com – I use wpa_supplicant to configure the wireless connection. Now I have a problem in that the network service starts before wpa_supplicant so this happens: Bringing up interface wlan0: Determining IP information for wlan0... failed; no link present. Check cable? When I after that restart the network service the wireless connection then gets an IP and works. I was reading about altering the start order by changing the the start order number in the respective init script. This is it in wpa_suplicant: # chkconfig: - 23 88 And this is it in network: # chkconfig: 2345 10 90 So if I und (HowTos)

Stories similar to Changing service startup order

I am running a version of RHCE6 on my laptop. I uninstalled the default NetworkManager in order that I could configure the network all in the command line. The Ethernet part is okay, but I have problem bringing up the wireless interface. What I got is:

Bringing up interface wlan0: Determining IP information for wlan0... failed; no link present.

NetworkManager is a powerful tool for setting up a wlan connection, especially if you connect the laptop to multiple access points. One drawback is that the user accounts must be given access to the pass phrase. Another is that there is no wlan connection in run level 3, because nm-applet is an X application.

I have installed on my CentOS server postgresql service and another one called netnfork.

I am on Ubuntu 12.04, 64-bit, fresh install. I have a wired connection (eth1 interface), the IP address is assigned by DHCP, and PEAP authentication (wpa_supplicant) is set up.

My problem is that network does not start at boot. I have to log in without internet connection, and then I have to start network-manager manually (sudo start network-manager).

I am running Ubuntu Server 12.04. I have a wireless USB card. When I begin the boot process I see:

Waiting for network configuration

It turns out that the network never comes up. But once I get to the command line, if I type: ifup wlan0, then I have network access.

Hi there,I'm trying to start wpa_supplicant automatically when starting multi-user.target without going through something fancy like netcfg or NetworkManager. So I have done systemctl enable wpa_supplicant@wlan0Unforutnately, this doesn't work.
