Hi-

I tried `ifdown eth1 ; ifup eth1` and it [failed].

from /var/log/messages:
Mar 22 13:05:18 localhost dhclient: DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 14
Mar 22 13:05:32 localhost dhclient: DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 20
Mar 22 13:05:52 localhost dhclient: DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 4
Mar 22 13:05:56 localhost dhclient: No DHCPOFFERS received.

Encryption is enables at the WAP, and I have verified the
settings in wireless.opts:
    INFO="Wavelan IEEE example (Lucent default settings)"
    ESSID="linksys"
    MODE="Managed"
    KEY="D961B30DC736B4BC716DCF0431"

I notice from iwconfig that it has an empty string as an ESSID
and says 'Encryption key:off'.  Doesn't seem to be picking up
the params from wireless.opts.

eth1      IEEE 802.11-DS  ESSID:""  Nickname:"HERMES I"
          Mode:Managed  Frequency:2.457GHz  Access Point: 44:44:44:44:44:44  
          Bit Rate:2Mb/s   Tx-Power=15 dBm   Sensitivity:1/3  
          Retry limit:4   RTS thr:off   Fragment thr:off
          Encryption key:off

This is all I have in ifcfg-eth1:
DEVICE=eth1
BOOTPROTO=dhcp
ONBOOT=no

Thanks,
Clark
