There is no cable plugged in when I use the wireless.

Here is ip addr with no cable and just wireless. However, I have manually removed the offending eth0 entry...I can reboot and run this again with the offending eth0 entry if needed.

root@orca:/etc/network# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
    link/ether 00:24:e8:fa:3a:aa brd ff:ff:ff:ff:ff:ff
    inet6 fe80::224:e8ff:fefa:3aaa/64 scope link 
       valid_lft forever preferred_lft forever
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 00:24:d6:4d:f4:5c brd ff:ff:ff:ff:ff:ff
    inet 192.168.25.150/24 brd 192.168.25.255 scope global wlan0
    inet6 fe80::224:d6ff:fe4d:f45c/64 scope link 
       valid_lft forever preferred_lft forever

My Debian testing laptop running gnome has two interfaces - eth0 and wlan0.
When I switch to wlan0, the routing table has an entry for eth0, so I
cannot access my local network.
root@orca:/home/mark# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use

192.168.25.0    *               255.255.255.0   U     0      0        0 eth0
192.168.25.0    *               255.255.255.0   U     0      0        0
wlan0
if I remove the eth0 line, I can connect to my local lan.
How do I permanently remove this route? I can do it manually with route del
-net....., but that does not survive reboot. I have no idea where this
setting is created.
When I switch to eth0 (ie plug in a cable), I get this routing table, which
is correct.
root@orca:/etc/network# route

default         gateway         0.0.0.0         UG    0      0        0 eth0
link-local      *               255.255.0.0     U     1000   0        0 eth0
192.168.25.0    *               255.255.255.0   U     0      0        0 eth0
Thanks,
