Hi Dan,
As far as I am aware my connections are "system" connections. I have configured
the Network interfaces using the system-config-network tool. When I use the
"network" service the eth1 wireless network comes up fine at boot. When I use
NetworkManager the eth1 wireless network does not come up at boot. There is the
error: "Waiting for network... [FAILED]"
If the NetworkManger service is running (eth1 has not come up) and I run
"service network start" the eth1 interface still does not come up. If
I stop the NetworkManger service and again run "service network start" then
the eth1 interface comes up ...
The configuration files are:
/etc/sysconfig/network-scripts/ifcfg-* files are there:
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth1
/etc/sysconfig/network-scripts/ifcfg-lo
/etc/sysconfig/network-scripts/ifcfg-Vodaphone
/etc/sysconfig/network-scripts/ifcfg-eth1 is:
# Intel Corporation PRO/Wireless 2915ABG [Calexico2] Network Connection
DEVICE=eth1
HWADDR=00:16:6F:8A:E1:95
ONBOOT=yes
BOOTPROTO=dhcp
TYPE=Wireless
NM_CONTROLLED=yes
USERCTL=yes
PEERDNS=yes
IPV6INIT=no
MODE=Auto
^^^^ This is the problem. "Auto" is not a valid mode.
Dec 1 09:59:05 think NetworkManager: ifcfg-rh: error: Invalid mode 'auto'
(not 'Ad-Hoc' or 'Managed')
you'll probably be seeing something on the console when running "ifup
eth1" like this:
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Invalid argument.
Since all ifup-wireless does is send $MODE to iwconfig, and "auto" is
not a valid mode.

nm-tool also outputs the error on stderr:
