[...] Sorry I misread, you talked about the "index". The same remark can be done, the text following the command line explains the "3": - The wepkey means setting the selected WEP key. It should in the format index:key, if the index is not given, key 1 is set. That is to say we need to set the index if we use keys other than the first key. I'll stop to pasting, the rest of the text also invites the read to look for more information inside ifconfig(8) manual page and the /etc/wpa_supplicant.conf config rings bells one this points. -- Marc
