The loopback interface has nothing to do with your problem. 127.0.0.1/8 on lo is normal.
You should configure your laptop to use DHCP (since you don't seem to understand networking enough to use manual configuration to get it working), plug it in, automatically get a lease, and then connect your browser to 192.168.55.4. Boom, done.
