[Wine] Connecting to the Internet

[DUSwimming08]

I have installed Wine and a few programs are working but when I try to register them online it says that an internet connection could not be found. 
I have tried these steps that I found online:
In the Terminal window, type "hostname" without the quotes.

3) It will return your IP Address, your domain, and your hostname for your internet connection like this (xxx.xxx.xxx.xxx yourhost.yourdomain.com yourhost)

4) This result should match your whatever your local ISP values are. If they match, then we need to try something else. If they are different, follow step 5.

5) Find and open the file ~/etc/hosts and see if there is an entry for your hostname. If there is an entry, you need to change it. If there isn't an entry you need to add one. The following example assumes your hostname is "yourhost" and your network IP address is 192.168.0.2

Original Entry (may also be blank):
xxx.x.x.x yourhost.yourdomain.com yourhost

Change this to (or add, if there is no such line):
192.168.0.23 yourhost.yourdomain.com yourhost

Save, exit, reboot, and try to register those software titles again.

But this is the only thing I get when I type hostname into terminal:
First name-lastnames-MacBook-Pro:~ firstnamelastname$ hostname
firstname-lastnames-MacBook-Pro.local

In the network settings it said IPv4 address is 192.xxx.x.xx under AirPort.....When I click on the Ethernet Adaptor (en4) the IP address is 160.xxx.xx.xxx (not sure if i should send those numbers online) but says it has a self-assigned address and will not be able to connect to the internet....not really sure what it all means airport is green and ethernet adaptor is orange, while ethernet and firewire are red.....

Not really sure how to find my local ISP values and i type in that file name (~/etc/hosts) in search and nothing comes up.....sooooooooo not too much luck with the instructions yet...

Can't really figure out anything and am pretty stuck...any help would be greatly appreciated.
