Hi Patrick

Can you run this test and then tell us the results - World Speedtest.net

ok there it is i think its bad will a better modem help because i got a better router as a stated before but what i really want to know what do i need to do to be able to play xbox live without getting lag when i try to play a game online.

Truthfully I don't know the Internet Bandwidth requirement of the XBox.

I'm guessing you are experiencing lag now because you are sharing a slow DSL connection. It might be in your best interest to upgrade to a faster DSL connection if you want to play online games and share your connection at the same time. Your modem should handle faster speeds. Contact your local Internet Provider and see if you can upgrade to a faster connection.

what exactly is DSL?

DSL is a type of internet connection that shares your phone line with your home phone.
Is your modem not a DSL modem?
Do you have a cable modem instead?

i have a cable modem

You can still call your internet service provider to see if you can upgrade to a faster connection. That is if you feel you want a faster connection.

will if that will stop the lag in my games on xbox live then hell yea ill do it but i dont want to do it just to see no effect or change.

I tell you what you can try

Play the game without your exchange student online. While playing the game have the exchange student go online.

If you notice a difference with a shared internet connection then chances are you need a faster connection to keep up with both computers.

And if your exchange student does any major downloads then you might notice a difference regardless what speed your internet connection is.
