|You can't use your Xbox to establish a new connection to a different ISP. |
Every router/modem has it's own setup utility for establishing a connection to your ISP.
However, if the router/modem is supplied by your new ISP it should already be set up to connect to them automatically when you connect the appropriate cables.
All you should need to do then is supply the username & password of your new internet account when you signed up.
If your new router was not supplied by your ISP you will have to set it up as per the instructions supplied with it.
When you have a connection working you can then setup a new wifi connection on your Xbox just same as you did with your old ISP, only the network name & wireless key will be different of course.
