OK. I've disabled WEP.
My ifcfg-ath0 file:
DEVICE=ath0
BOOTPROTO=dhcp
ONBOOY=yes
HWADDR=<macaddress of my network card>
METRIC=10 /* What's this? */
MII_NOT_SUPPORTED=yes /* What's this? */
WIRELESS_MODE=Managed
WIRELESS_ESSID=<my essid>
WIRELESS_FREQ=2.437 /* Channel 6 - right? */
WIRELESS_RATE=auto /* Case sensitive? */
Output of ifconfig ath0:
Link encap: Ethernet HWaddr <my cards macaddress>

(The xxxx:yyyy:zzzz is of course my substitution)

Result from ifup ath0:
Error for wireless request "Set Frequency" (8B04) :
Set failed on device ath0 ; Invalid argument.
Determining IP information for ath0... done.
And yes! I am now able to make contact in spite of the error message related
to frequency.
So I try to reinstall my wep key. According to my AP I have a Shared key
system with a 128 bits key. My ifcfg-ath0 file now has the new line
WIRELESS_ENC_KEY=5a3c55<and so on...>
Does this require a special format? Hyphens? Anything to designate it as a
hexadecimal number?
I am not able to reach the network.
