The best answer is probably to use trunk. Along the lines of what other people have said, your problem is two interfaces on the same subnet in the same machine. Another way to fix that is to carve the wifi network off into 10.10.20.x and use appropriate subnet masks. Then your new default route will be 10.10.20.1 and it won't try using re0. Something to consider if you ever want different policies for wired and wireless, but probably too much work just to make one laptop work.
