To assign a consistent IP address to a device on your MI424WR router, you must configure a DHCP reservation within the router’s web interface. This process binds the device’s MAC address to a specific IP in the DHCP pool, ensuring the router always hands out that same address without requiring manual static configuration on the host machine itself.
Prerequisites and Network Access
Before configuring the reservation, ensure your computer is connected to the MI424WR network, either via Ethernet cable or Wi-Fi. You need the IP address of the router to access its administrative panel. Most MI424WR units default to 192.168.1.1. Open a web browser and enter this address into the URL bar. If the standard address does not work, check your computer’s network settings for the "Default Gateway" value, which serves as the correct login URL.
When prompted for credentials, use the default username and password provided with your router documentation. These are often printed on a label attached to the device. If you have changed these credentials previously, you must use the updated ones. Failure to provide valid administrative access will prevent you from modifying any network settings.
Locating the DHCP Reservation Settings
Once logged into the router interface, navigate to the section responsible for local network management. The exact menu structure can vary slightly depending on the firmware version installed on your MI424WR, but the functionality remains consistent. Look for a tab labeled Local Network or DHCP. Within this area, find the subsection for DHCP Server or DHCP Reservations.
It is crucial to distinguish between setting a static IP on the client device and setting a reservation on the router. Setting a static IP on the PC manually can lead to conflicts if another device claims that address. Using the router’s reservation feature is the safer method because the router controls the assignment.

Identifying the Target Device
To create a reservation, you need the Media Access Control (MAC) address of the device you wish to fix. The MAC address is a unique identifier burned into the network interface card. You can find this address in two ways:
- On the Router Interface: Many MI424WR interfaces display a list of currently connected devices under the DHCP status page. Identify your device by its hostname or current assigned IP and note its MAC address.
- On the Host Device: On Windows, open the Command Prompt and type
ipconfig /all. Look for the Physical Address field. On macOS or Linux, useifconfigorip link showto find the hardware address.
Write down the MAC address carefully. It typically looks like 00:1A:2B:3C:4D:5E. Ensure there are no typos, as an incorrect MAC address will result in the wrong device receiving the reserved IP.
Configuring the Static Lease
Navigate back to the DHCP Reservations or Static DHCP section. Click the button to add a new entry. You will be presented with fields to input the MAC address and the desired IP address.
Enter the MAC address of your target device exactly as recorded. Next, specify the IP address you want to assign. It is best practice to choose an IP address that falls within the router’s DHCP range but is outside the dynamic allocation block to avoid accidental overlap. For example, if your DHCP pool starts at 192.168.1.100, you might reserve 192.168.1.50. This ensures the router never accidentally assigns that specific address to a different device.
Save the changes. The router may prompt you to reboot or simply apply the settings. A reboot is often recommended to clear the existing DHCP lease table, forcing the router to immediately recognize the new reservation. After the router restarts, the specified device should request an IP address upon connection, and the router will now consistently provide the reserved address.
Verification and Troubleshooting
After applying the configuration, verify that the reservation is working correctly. Disconnect the target device from the network and reconnect it. Check the device’s network settings to confirm it has received the reserved IP address. Simultaneously, check the router’s DHCP client list to see if the device is listed with the correct IP.
If the device receives a different IP, ensure that the DHCP server is enabled on the router. Also, verify that the MAC address was entered correctly, including case sensitivity if required by your specific firmware. In some cases, clearing the DHCP lease cache on the router can resolve lingering issues where the old dynamic assignment persists.

Frequently Asked Questions
What happens if I set a static IP on my PC instead of using the router?
You can set a static IP directly on the operating system, but this carries a higher risk of IP conflicts. If another device on the network is also configured statically or if the router’s DHCP pool overlaps with your manual selection, connectivity issues will arise. Using the router’s reservation feature is generally preferred for home networks.
Can I change the reserved IP address later?
Yes, you can modify the reservation at any time through the router’s web interface. Simply edit the entry associated with the MAC address and update the IP field. Save the changes, and the next time the device connects, it will receive the new address. Note that changing the IP may require updating any port forwarding rules associated with the old address.
Does this configuration affect other devices on the network?
No, configuring a DHCP reservation for one device does not impact others. The router continues to manage the rest of the DHCP pool normally. Other devices will still receive random available IPs from the dynamic range, while only the specified MAC address triggers the fixed assignment.
Why is my device still getting a different IP after setting the reservation?
This usually occurs because the device holds onto an old DHCP lease. You must release and renew the IP address on the client device, or reboot the router to clear its lease table. Additionally, double-check that the MAC address entered in the router matches the physical address of the network adapter exactly.
Is this method compatible with all MI424WR firmware versions?
The core functionality of DHCP reservations exists across most firmware versions for this model. However, the menu labels may differ slightly, such as Static DHCP versus DHCP Reservations. If you cannot find the option, look for any section related to local network addressing or DHCP server settings.
