For using my Cisco Aironet 350 on my Sony Vaio laptop that goes
between several WiFi networks using WEP I just created a script that I
use in /etc/network/interfaces that handles the mapping for me... The
script basically scans the network and tries to match an ESSID it finds
from scanning to a mapping config line...
What I end up with in the interfaces file is along the lines of:
mapping eth1 wifi0
script /path/to/get-essid.sh
map ESSID-Office wifi-office
map ESSID-Home wifi-home
iface wifi-home inet dhcp
wireless_mode managed
wireless_esside ESSID-Home
wireless_key <10 or 26 hexadecimal key>
wireless_enc on
iface wifi-office inet dhcp
wireless_mode managed
wireless_esside ESSID-Home
wireless_key <10 or 26 hexadecimal key>
wireless_enc on
I am not writing this from the laptop at the moment so I don't
have the get-essid.sh script handy but if there is interest I'll try to
get it posted later...
Regards,
Jeremy
