You probably already use DHCP a lot more than you realize.
DHCP reservations work by binding an IP address to your system’s MAC address.
Even if it never sees that MAC address again, it will continue to reserve that IP address.
The only problem is, not all routers support the configuration of DHCP reservations.
Bring up a command prompt (key in cmd into the Start menu) and key in ipconfig.
You’ll need to look for the Default Gateway IP address.
Once you’re in that menu, right-choose your connection adapter > Status > Details.
In the details menu, you’ll see your default gateway listed.
Your router should prompt you for a password, like in the screenshot above.
If you’ve previously configured a password for your router, enter it and click OK.
If not, then it should still be at the default value.
Linksys and a lot of other routers use a blank username and the password “admin” for authentication.
If that doesn’t work, consult your manual or Google for the default password.
On Linksys, the DHCP prefs are on the first page when you login.
Right-hit your data pipe adapter, and go to Properties.
In the Properties menu, highlight “Internet Protocol Version 4 (TCP/IPv4) and click Properties.
In this menu, you’ll be able to set your IP address.
Be sure to stay in the same subnet as your router (in most cases, 192.168.1.X).
On a Linksys router, this information is located in the “Status” tab.
All other routers should be similar.
