Whoa! Thanks for bringing that to my attention--I didn't even notice that thing! Well, I'm not 100% sure about this, as you can connect your Wii to the internet, but if you go on http://community.guitarhero.com, you can put your scores up, have tournaments, etc. Maybe you connect the guitar directly to the computer for this, I'm not sure. But I think it's for something like that. :)
::Edit::
The scores are uploaded via the Nintendo WFC, that is NOT the purpose of the jack on the guitar.
Rumors speculate that it is currently an unused expansion. It may be for something along the lines of an effects pedal.
As a precaution, I do not recommend hooking the guitar up to a phone line, modem, or your computer without further information as to its purpose.

Its supposed to be an effects port, unused as of now.

Their are several reasons as to why the internet light on the Embarq DSL modem is not coming on. One is the modem maybe in whats called Bridge modem. Which means it just translating DSL signal to a signal your PC can understand. The Firewall and routing of data have been disabled. Basicly the internet light means that modem is hold a ip address for the internet. Other possiable issue is that maybe issue with Embarq Network. Contact Embarq HSI Tech support for any help.
You will need to buy a new modem that is designed for your DSL modem. This is due to the fact that the modem is designed to use the dsl signal opposed to the cable modem.

Port speed is how fast the computer talks to the modem. Modem speed is how fast the modem talks across the phone line to the other modem.
