Hi Christian.

No cigar I am afraid :-(

Different networks. My wired connection comes from my ADSL modem using DHCP. My
WIFI connection comes from a DLINK box on a different network using DHCP from
my Solaris box. (My desktop and the Sparc both have two NICs.)

Nowhere do I set a default route. My xwlan.cmd for when wifi shuts down is:

      if WLan._Profilename = "Home" then do
        'dhcpmon -l';
        'dhcpmon -t';
        'ifconfig lan1 down';
        'ifconfig lan1 delete';
        'route -fh';
        'arp -f';
        'dhcpstrt -d 10 -i lan0';
        'ifconfig lan1 192.168.255.251';
      END;
