Problems with 2 network interfaces up at the same time

I am really a noob, so take it easy on me, please

I have gentoo running on my ibm t30 laptop. I need to use both, wireless and wired networks at the same time, but for some reason once I enable eth0 I loose eth1 and vice versa. Only rarely I can actually get both networks working at the same time. Any suggestions?

If they're on the same subnet then the kernel itself will only use one.

What exactly is the error your seeing BTW?

I am not seeing any errors. I just cannot ping computers on both adapters at the same time. The network cards aren't using the same subnet btw.
thanks.

Show us the output of "ifconfig" and "route -n" while both NICs are active.

Try to enable routing:
