I just googled "how to find my ISP address" - that takes you to various sites where you can click on a button and your ISP address comes up.  I knew you could do it as son did this for me when he set up router.

- I also googled how to find MAC addresss - didn't look at the sites that came up but there is obviously info out there.

Hope that helps
