Use WinSCP and open /etc/config/network and then just copy/paste this over for wan and lan:

        option proto 'none'
        option enable '1'


config interface 'lan'
        option ifname 'eth1'
        option proto 'dhcp'
        option type 'bridge'
        option enable '1'
        option broadcast '1'
        option peerdns '0'
        option dns '208.67.222.222 208.67.220.220'
