The laptop is not on the same network.
The laptop is connected to a Clearwire wifi modem.
The Desktop is connected to a Time Warner broadband cable.
I am not well educated on internet modems and router so I do not know the terminology well.
But the two computers are definitely on different networks independent from each other with two different ip addresses.
The laptop is running linux mint, Also I have an iphone and I cannot get the domain name now that it points to a DDNS nameserver with dnxexit.com.
I can connect on a firefox web browser to /var/www/html/ with an index.html, info.php and wordpress file.
but I cannot connect to my domainname.com.
