This wikiHow teaches you how to enable your router's Dynamic Host Configuration Protocol (DHCP). DHCP automatically assigns a device-specific IP address to each device on your router's network, which ensures that no two devices will share an IP address and thus encounter connection errors.

Log into your router's page if prompted. Some routers are protected by a username and password. If you didn't set the password, you can usually find it in your router's manual. [9] X Research source
- You can also look up your router's model number and name online to see if you can find the default username and password.
- If you set a password but no longer remember it, reset your router to restore the factory settings.

Open your router's settings. Each router's page will differ slightly from other routers; you'll likely find the router's settings.
-
Find the DHCP section. This will usually be in the "Network Settings" section (or your router page's equivalent). If you can't find DHCP there, look for it in the "Advanced" settings, "Setup" settings, or "Local Network" settings.
-
Enable DHCP. Click the Enable switch, checkbox, or button. In some cases, you may first have to click a Disabled drop-down box and then select Enabled from the drop-down menu.
- You may also have the option to change the number of devices that can use your router. Be careful if you do this, since allowing for too few devices will result in connection errors for one or more devices.
-
Save your settings. Click the Save or Apply button to save your settings. Depending on your router, you may also be prompted to restart your router in order for the changes to take place.

QuestionI tried using admin and password to log into my router, but it won't let me in. It asks for city I was born in and father's middle name. I input the info, and it says that the info is not correct! What should I do?R2_d2000Top AnswererI sounds like someone else set up your router, but didn't give you the information. You will have to reset your router back to factory settings. There should be a reset button on the back of the router. You can push it with a paperclip, and hold it down for about 30 seconds. This should reset the router.
