First thing's first: do NOT even bother with bridging if you still use wifi
to access the internet. If you HAVE to use wifi, use NAT instead (there's
an example in the first link)

Do some basic trobleshooting:
- is the HOST able to connect to the internet?
- what does these commands show on the host:

brctl show
ip ad li
ip route
ethtool eth0
ping -n -c 1 192.168.0.1
ping -n -c 1 8.8.8.8
ping -n -c 1 google.com
cat /etc/resolv.conf

My GUESS is you're missing something simple, like:
- the cable is unplugged
- you're trying to setup bridging with eth0 while you're connected using
wifi
- your interface name is not eth0, but something else
- you previously use DHCP, and now since you use static address your
resolv.conf is empty since you haven't set it up
