This wikiHow teaches you how to enable DHCP (Dynamic Host Configuration Protocol) on your router. DHCP will automatically assign a special IP address to each device on the router network. This is to ensure that no devices share the same IP address, which could cause problems with the connection.

Part 2 of 2: Enabling DHCP

Step 1. Start a web browser, then enter the address of your router
The router page will open.

Step 2. Log in to the router page when prompted
Some routers are username and password protected. If you've never changed your router's password, try looking up the password in your router's manual.
- You can also search the model number and name of the router online to find the default username and password for that router.
- If you've ever changed your password but forgot it, reset your router to factory reset your device.

Step 3. Open router settings
Each router has a slightly different page view, but you'll most likely find a settings page there.

Step 4. Look for the DHCP section
This is usually located in the "Network Settings" section (or something similar). If you don't see DHCP there, look for it in "Advanced" settings, "Setup" settings, or "Local Network" settings.

Step 5. Enable DHCP
Click the switch, checkbox, or button Enable. Sometimes, you may have to click the drop-down box Disabled, then select Enabled from the drop-down menu.
You may also be given the option to change the number of devices that can use the router. Be careful when doing this because if you allow only a few devices, some devices will not have an internet connection

Step 6. Save your settings
Save your settings with the click of a button Save or Apply. Depending on the router you're using, you may also need to restart your router for the changes to take effect.
Tips
We recommend that you follow the instructions provided by the router manufacturer if you wish to change the settings. Each router has different settings
Warning
- Make sure you can physically access the network device in case you have to restore the device to factory settings.
- Never enable DHCP on an insecure network (without using a password).
