The following is my route output. eth0 is my wired network and eth1 is my wireless network. Only wired one has access to internet. If I enable wireless, I am not able to access internet, it tries to access via eth1 and I get 404 page of the wireless router. Why does eth1 have higher preference though default is eth0 (link)?

It looks like it randomly tries on both interfaces. Is there a way to set to use only eth0 ?
