Re: Wireless card detection

Hello people,

Since I installed FC6 I'm experiencing some problems with my ipw2200.
Sometimes, when I boot, the wireless card is not properly detected.
The output for ifconfig -a is:

__tmp2093065627 Link encap:Ethernet  HWaddr 00:0E:35:FD:AA:0F
         BROADCAST MULTICAST  MTU:1500  Metric:1
         RX packets:1284 errors:0 dropped:0 overruns:0 frame:0
         TX packets:1284 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:1000
         RX bytes:3144632 (2.9 MiB)  TX bytes:3144632 (2.9 MiB)
         Interrupt:16 Memory:54020000-54020fff

while usually is eth1.

If I try to use that name with for example dhclient, I get:
SIOCSIFADDR: No such device
eth1: unknown interface: No such device
eth1: unknown interface: No such device
Bind socket to interface: No such device

The problem only disappears after rebooting (sometimes I have to reboot twice)

I can not find any pattern here.
I looked for in bugzilla and I couldn't find any bugs about this so, I
would like to know if more people has this problem (or if it is
solved) before reporting a bug.

Thanks in advance

Check /etc/sysconfig/network-scripts/ifcfg-eth1 for:

If not set, set it.  If set incorrectly, set it correctly.

Also check your firmware version:

# ls -l /lib/firmware
-rw-r--r-- 1 root root 191142 Mar  7  2006 ipw2200-bss.fw
-rw-r--r-- 1 root root 185660 Mar  7  2006 ipw2200-ibss.fw
-rw-r--r-- 1 root root 187836 Mar  7  2006 ipw2200-sniffer.fw

Symptoms are exactly as you describe.  Workaround is to:

# ifdown eth1
# rmmod ipw220
# modprobe ipw2200
# ifup eth1

That should work every time, but indicates that the firmware may be bad, or HWADDR is wrong in the ifcfg-eth1 file.

Good luck!
