I have a P3 Desktop and recently bought an HP Laptop dv 2122tu. I have got cable net on my desktop. However, when I tried to connect that cord to my laptop, I am unable to connect to that net. The cable provider says that I ll have to go in for a new connection as one IP Address cannot be used in both. I want to use the net in both, depending on my use. Is there any way that this problem can be solved? Can I connect my laptop to the desktop and through that connect to the net?
