dual nic's, dual networks, setting this up? [SOLVED]

Hi,
I have a laptop with wireless (rt2500) and wired nic. Both work fine, but I am in a situation where I need to connect the wireless to one network, and the wired to another network. (Wireless to the internet, and wired to small home network). Im not trying to bridge them. I can set this up pretty easily, just using DHCP for both the wireless and wired, but after 15 minutes to an hour, requests I make on the wireless side try going over the wired network.
I tried fix it by:

route add -net 10.18.0.0 netmask 255.255.0.0 ra0
route add -net 192.168.1.0 netmask 255.255.255.0 eth0

but still after a half hour or so the requests I make on wireless (internet) try going over the wired interface.
Any ideas on how to keep these two interfaces associated with their respective networks?
Thanks

Re: dual nic's, dual networks, setting this up? [SOLVED]

I just had an AHA moment and think I solved my problem.

route -n gives me

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
10.18.0.0       0.0.0.0         255.255.0.0     U     0      0        0 ra0
0.0.0.0         192.168.1.1     0.0.0.0         UG    0      0        0 eth0
0.0.0.0         10.18.0.1       0.0.0.0         UG    0      0        0 ra0

So both eth0 and ra0 have destinations to the 0.0.0.0 network. Thats no good because only ra0 really goes to the internet. so I just did

route del -net 0.0.0.0 eth0

So now

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
10.18.0.0       0.0.0.0         255.255.0.0     U     0      0        0 ra0
0.0.0.0         10.18.0.1       0.0.0.0         UG    0      0        0 ra0

Only one route for the internet, no more problems
