Internet problem

[adirawat20]

Hello guys.

I am having a internet problem.
I am having Sony PS3 and a desktop.

I want to connect my both system same time at internet.
But only one of system connects at a time.
I have heard it is due to ip address. I should have 2 ip address.
Is there a way so that i can increase my ip address or make my both system online.

Maybe u need multiple server at one time. b'coz due to house use of internet there is only 1 allocated IP address. Consult expert for more information!
