I have recently installed CentOS 6 on a system with a Realtek 8180L wireless card. The wireless card is detected properly and uses the rtl8180 driver. But it connects to our wireless network only after logging to the Desktop Environment (GNOME) and using the Network Manager Applet. In order to make the wireless card connect to the network automatically at system start up, I edited the Connection using the Network Manager Applet and checked "Connect Automatically" and "Available to all users" options. However, while booting the system, the following error message is displayed when the wireless network interface is brought up.
Device does not seem to be present, delaying initialization
But as soon as a user logs on to the Desktop, he can connect to the network using the NM Applet.
I have also toggled between using DHCP and Static IP Address for the the wireless card but it makes no difference. The SSID is not being broadcast and the Wireless Access Point / Router uses WPA-PSK.
TIA,
