1. Set your pc to get its ip from the first router… this step is important to add a lease for it and we can make it a static address later if you want.
2. Log in to the 1st router (typically you use a browser for this) and look for the dhcp settings.
a. You should have a range of address (often called a scope) eg. 192.168.0.100 – 192.168.0.200… for a home system this gives out 100 addresses and as the router lives at .0.1 we want the numbers given out to new machines to be well away from this number i.e make certain that the scope don't give out its own address.
b. Look under clients and you should see the mac address of your pc… assuming {you did 1 above} then the pc will probably be # 0.100 but a ipconfig will...
