Makevali... don't take this the wrong way... but you're an idiot.

At least when it comes to computer stuff.
I'm absolutely serious here; you have no idea what you're talking about, so your best bet is to listen very carefully to what we're saying.
The "Fragnetics" you're referring to is a read-out of the "ping" (in other words, the strength of your connection) to the Fragnetics server. Since it's 0, it means you are not connected to the server.
Since you're posting on this forum, that means your internet is obviously functioning fine otherwise, so it's an issue that's specific to your computer's compatibility with this game.
Now here's the answer to what you were talking about: If you type your IP Address into the Firefox browser, you'll open the Modem configuration window. It'll ask for a username and password - unless it's been changed, the username is your Modem's model no. (which is 'WBR1310' for you) and the password is 'admin' (again, unless somebody changes it)
You can then fiddle with almost anything, including that 7777 port, but be very careful about it. Follow a guide or something.
I think that's what you were talking about, but I'm not so sure it'll help.
