Well, yeah you definitely need to set a static ip. It might not be the solution to your current problem, but it might help. Think about it... port forwarding is to make sure that all xbox live traffic goes straight to your xbox. So, you forward all the ports that xbox live uses to your xbox. Your router doesn't really know which device is your xbox, it just knows what ip address you told it to forward the ports to. So, if you just let your xbox get assigned any ip address by your router, chances might be that it won't get the ip address that your xbox live traffic is forwarded to. That xbox live traffic might be getting forwarded to your desktop or somebody else's laptop. So yeah, everytime your xbox is turned off and on, it could get a different ip address.
"For the static ip, how do I know what info to enter?"
Anything that is within your router's range. My linksys router's range is 192.168.1.100 - 192.168.1.149. And I could change that range if I want. So, I have about 7 or 8 devices connected to my router when everything I use is connected, so I am going to assign it 192.168.1.110. Those first 8 devices on my network will be assigned the first 8 available ip addresses, considering they don't have static ip addresses themselves. So, 192.168.1.100 - 192.168.1.107 will be used up. 192.168.1.110 will never be used by other devices since you don't have enough devices to reach that. You could assign something like 192.168.1.105, but if your xbox is off and something else using DHCP or dynamic ip addressing is on, it might take 192.168.1.105. I'm not really sure if your xbox would kick it off or if it wouldn't be able to connect or what, but it's just best to avoid conflict.
Should I use my laptops IP?
No, every device needs it's own Ip address I'm pretty sure.
Or a seperate ip for the Xbox?
Yes, this is the way to go.
If seperate, do I make it up or is there a certain IP I need to enter?
As long as it is within your router's range it should be ok. Just make sure that ip address that ports are forwarded to and your xbox's static IP address are the same.
That is how you normally do it. But, I'm not sure if anything changes since you are using a shared internet connection.
