[Wireless Router] How to manually assign IP around the DHCP list?
In general, the device connected to ASUS router will receive a dynamic private IP address from router DHCP server, like 192.168.1.3. However, if you want to share files in a computer to other devices, then you might need a manual assign IP function to set a static IP for the computer so you don't need to search and confirm the IP address of the computer every time when you want to access it.
To assign a fixed IP address for your devices, you may follow the steps below.
Method1：You can assign a fixed IP address from your device's network card. (For how to configure the built-in network card of your device, please contact the device manufacturer.)
Method2: Set up a fixed IP for device via ASUS router DHCP server.
Step1. Connect your computer to ASUS router via Wi-Fi or Ethernet cable.
Note: Wired connection is recommend to avoid setup interruptions due to unstable wireless network signals
Step2: Open a web browser and navigate to Web GUI. http://www.asusrouter.com
Step3: Enter your login username and password on the login page and then click [Sign In].
Note: If you forget the user name and/or password, please restore the router to the factory default status and setup. (The default username and password is admin/admin).
Please refer to [Wireless Router] How to reset the router to factory default setting? for how to restore the router to default status.
Step4: Go to [Advanced Settings] > [LAN] > [DHCP server], you can find the IP address range of RT-AX92U is 192.168.50.2 ~ 192.168.50.254.
Step5: Find [Enable Manual Assignment] and click [Yes] to enable manual assign function.
Step6: In Manually Assigned IP area, please fill in the device MAC address and the IP address binding to this device only.
Client Name (MAC Address)：Use the dropdown list to choose the device or manual enter the device's MAC address.
IP address：Enter the IP address that you want to bind to this device. Please make sure the IP address needs to be in the IP pool of your DHCP server.
For example, if the IP pool of your router’s DHCP server is 192.168.50.2~192.168.50.254, you should enter an IP address within this range, like 192.168.50.75.
DNS server (Optional)：Default is blank. You can enter the preferred DNS server if needed.
Step7: Click the "+" icon and the [Apply] button to complete the setting.
