connecting to the internet using the USB

i recently removed angstrom from the emmc and installed the ubuntu 13.10 image to the emmc (https://rcn-ee.net/deb/microsd/saucy/BBB-ubuntu-13.10-2013-12-17-4gb.img.xz)
i cannot, however connect to the internet using the same methods i used on angstrom. what do i do ?
this is how i used to connect to the internet using angstrom.
run this on puTTy → /sbin/route add default gw 192.168.7.1
the i used to open etc to modify resolv.conf to add nameserver 8.8.8.8 to the file and i used to connect to the internet , now, however with the ubuntu 13.10 this does not connect , i donot get any errors but pinging 8.8.8.8 shows that no internet connection has been established . what do i do ??

What you need to do is search google for “windows internet connection sharing with ubuntu”, until you find instructions that work for you. Possibly, iptables will be involved.
