How To Disable DHCP on ASUS Router?

DHCP (Dynamic Host Configuration Protocol) is a networking protocol that allows a device, such as a router, to assign IP addresses to devices on a network automatically. In some cases, it may be necessary to disable DHCP on your router to use a different device or service to manage IP addresses on your network. Please note that disabling DHCP may cause connectivity issues for some devices on your network, so it’s essential to be aware of this potential issue before proceeding.

If you have an ASUS router and want to know how to disable DHCP on ASUS router, this guide is perfect for this case. This post will walk you through the step-by-step process of disabling this feature while taking care of all the other things related to your network and devices. In addition, this discusses caution, necessary steps, and the advantages of disabling the DHCP on your router. But the steps may be a bit different depending on your router. Let’s uncover the mystery!

Cautions When Disabling DHCP on a Router

There are a few things you should consider when disabling DHCP on your ASUS router:

1. Ensure you have a plan for assigning IP addresses to devices on your network. If you use a different device or service to manage IP addresses, ensure it is properly configured and ready to go before disabling DHCP on your router.
2. Be aware that disabling DHCP may cause connectivity issues for some devices on your network. These devices will no longer be able to obtain an IP address from the router automatically and must be configured manually with a static IP address. Ensure you know how to do this for each device on your network. Therefore, understanding the process is vital before disabling DHCP on your router. 
3. If you have devices that rely on DHCP for their initial setup (such as some smart home devices), you may need to reset and set them up again after disabling DHCP.
4. Ensure you have access to the router’s web-based interface or configuration utility before attempting to disable DHCP. This will usually require a login and password, which you can find in the router’s documentation or by contacting the manufacturer.
5. Consider the potential impact on other devices on your network before disabling DHCP. If you have an extensive network with many devices, it may be more practical to use a different device or service to manage IP addresses rather than disabling DHCP on your router.

How To Disable DHCP on ASUS Router?

The method of disabling DHCP on the ASUS router is straightforward. All you have to do is log into your Web GUI, locate the DHCP settings, tweak them, and save the changes. The whole in-detail process looks like the following: 

Step 1: Set up the wireless router using the wired connection. 

• Connect the wireless router’s AC adaptor’s one end to the DC-IN slot while the other power-input-end to the wall socket or power outlet. 
• Use the bundled network cable to connect your computer to the router’s LAN outlet by plugging the appropriate ends into the correct slots. 

Step 2: Login into the ASUS Router Web GUI.

• Click the following link, [https://router.asus.com/], to launch the required web page. 
• Enter your username and password, and click sign in.  

Step 3: Access the DHCP settings.

• Once you’re logged in, the next step is to find the settings.
• For this, locate LAN > DHCP Server. 

Step 4: Disable the DHCP server.

• All you have to do here is to disable the DHCP server. But the process doesn’t end here; you must also follow the next steps.
• Once you have disabled the function, you must manually assign the IP addresses to the LAN devices. 

Step 5: Manually assign IP addresses to the devices. 

• Go back to the navigation panel. From here, go to Advanced Settings > Wireless > Wireless MAC Filter. 

• Choose Yes from the Enable MAC Filter radio button to enable the Wireless MAC filter. 
• Select the MAC Filter mode: Accept will only let us use the internet to add devices, while Reject will remove those devices from the router. 
• Enter the MAC address of the device you want to block in the Mac filter list. Click the “+” button to add it to the list. (Note: You can read the section below to find out the MAC address of a connected device.)
• Once done, click on the Apply button to save the settings.

Why Disable DHCP on a Router?

There are a few reasons why you might want to disable DHCP on your router:

• To assign static IP addresses to devices: Some users may want to set static IP addresses to specific devices on their network rather than having the router assign dynamic addresses. In this case, they may need to disable DHCP on the router to use their own IP address assignment scheme.

• To troubleshoot network connectivity issues: In some cases, users may want to disable DHCP on their router as a troubleshooting measure if they are experiencing issues with network connectivity. This can help to isolate the issue to the DHCP server and determine whether it is the cause of the problem.

• To use a different device or service to manage IP addresses on your network: Some users may prefer to use another device, such as a dedicated DHCP server, to manage the assignment of IP addresses on their network. In this case, they may want to disable DHCP on their router to avoid conflicts.
