big problem with ethernet and wlan

i am using arch linux stable in 0.7.2 with kernel 2.6.18-ARCH (it isn't manipulated)
the rc.sysinit process needs a long time to load the network daemon
sometimes it will fail and sometimes it load successfull, but my aliases for the network modules are everytime in an other order
first possibility: wlan module (modul ipw2200) is used as alias eth1 or eth0 and the ethernet device(modul e100) is used as the other one of eth0/eth1 (<- is the grammar right now?)

second possibility:
both devices have the same alias, i had this possibility yesterday (both had the alias eth1!) 

[thecrazylol@spoon ~]$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

eth1      IEEE 802.11g  ESSID:"ArcorWirelessLAN"  Nickname:"ArcorWirelessLAN"

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:1

sit0      no wireless extensions.

[thecrazylol@spoon ~]$ ifconfig
eth1      Link encap:Ethernet  HWaddr 00:16:6F:81:5C:4E

          RX bytes:800 (800.0 b)  TX bytes:800 (800.0 b)

[thecrazylol@spoon ~]$

third possibility:
the ethernet device is not listed on ifconfig output, only in iwconfig but the wlan device is listed everytime in iwconfig


the kernel put logs like the following in the logs: 

Oct 3 21:49:30 spoon ADDRCONF(NETDEV_UP): eth0: link is not ready
Oct 3 21:49:30 spoon e100: eth0: e100_watchdog: link up, 100Mbps, full-duplex
Oct 3 21:49:30 spoon ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

Re: big problem with ethernet and wlan

There are several solutions to making sure that your eth0 stays with your wired connection and eth1 for your wireless.


1) /etc/modprobe.conf 

alias eth1 ipw2200

2) Load the modules in MODULES array in the order you need them (lan drivers first, wlan second)
3) Bind the MAC address to iftab config. man iftab for more details.
4) Create a udev rules file, also binding mac to an alias.
This could look something like this:
/etc/udev/rules/my_new_eth.rules 

KERNEL="eth0", SYSFS{address}="aa-bb-cc-dd-ee-ff", NAME="eth0"

Try "ifconfig eth0 up" to see if that makes any difference for your wired NIC to see if shows up at all when running ifconfig. There's also the possibility that you're not using the proper driver for you network.
