Setting a static IP address can make your network setup more stable and predictable, especially if you use port forwarding, network sharing, remote desktop, printers, CCTV devices, NAS storage, or game servers. In this guide, you will configure a fixed IP address reservation on the D-LINK DSL-5300 router and then set the same static IP manually on your Windows PC.
A static IP ensures that your Windows computer always uses the same local network address instead of receiving a different one from DHCP each time it reconnects. This helps avoid connection conflicts and makes device management much easier.
Before You Start

Before making any changes, prepare the following:
-
Access to the D-LINK DSL-5300 admin panel
-
Your router login username and password
-
The MAC address of your Windows PC’s network adapter
-
A free IP address on your local network
-
Your router’s IP address, which is usually the default gateway
It is also a good idea to check your current network settings first so that you can choose an IP address that fits your existing subnet. For example, if your router uses 192.168.1.1, your PC could use something like 192.168.1.50, as long as that address is not already assigned to another device.
Part 1: Reserve a Static IP Address on the D-LINK DSL-5300 Router

This section sets a fixed IP mapping inside the router so the same device always gets the same address. According to your source, the process is done through the More Functions > Network Settings > LAN area of the router.
Step 1: Open the Router Control Panel
Start by opening your web browser and entering the router’s IP address into the address bar. This will bring you to the D-LINK DSL-5300 login page.
Step 2: Log In to the Router
Enter your router administrator credentials and sign in.
If you cannot log in, double-check that:
-
you are connected to the D-LINK network,
-
the router IP address is correct,
-
the login details have not been changed from their defaults.
Step 3: Go to More Functions
Once inside the router dashboard, navigate to the More Functions section.
This section usually contains more advanced network settings that are not shown on the basic home page.
Step 4: Open Network Settings and LAN
Next, click Network Settings, then open LAN.
The LAN settings page is where you manage local network addressing, DHCP reservations, and related options.
Step 5: Add a New Static Assignment
Scroll down the page until you see the option to add a new entry, then click Add.
This opens the form where you can create a reservation between a device and a specific IP address.
Step 6: Enter the MAC Address and IP Address Manually
Now enter the MAC address of your Windows PC and the IP address you want to reserve for it.
Step 7: Or Choose the Device from the List
Instead of typing the MAC address manually, you may also be able to select your computer from the device list by using Enter manually and choosing the computer name shown by the router.
This is often easier and reduces the chance of entering the wrong MAC address.
Step 8: Save the Reservation
After confirming the information, click OK.
Once saved, the router will remember that this Windows PC should always receive the chosen IP address.
Step 9: Confirm the Static Mapping
If everything was entered correctly, the router should now show the new assignment in its list.
At this point, the router-side reservation is complete. Your device now has a dedicated local IP address on the network.
Part 2: Set the Same Static IP Address on Your Windows PC

After reserving the address on the router, configure your Windows network adapter to use the same IP information manually. This ensures that both the router and the computer are using matching settings. The provided steps use the Windows network settings and IPv4 adapter properties.
Step 1: Open Network and Internet Settings
On your Windows desktop, go to the lower-right corner of the taskbar and right-click the network or internet icon. Then select Open Network & Internet settings.

This takes you to the main Windows networking panel.
Step 2: Open Adapter Options
Click Change adapter options.
This opens the classic Network Connections window where you can manage Ethernet and Wi-Fi adapters directly.
Step 3: Open the Properties of Your Network Adapter
Find the network adapter you are currently using, right-click it, and choose Properties.

Make sure you choose the correct adapter:
-
Ethernet if you are using a wired connection
-
Wi-Fi if you are connected wirelessly
Step 4: Open IPv4 Properties
In the adapter properties window, select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
The IPv4 settings determine the local address, subnet mask, gateway, and DNS used by your PC.
Step 5: Enable Manual IP Configuration
Select the checkbox for Use the following IP address.
This tells Windows to stop obtaining an address automatically and use the values you enter.
Step 6: Enter the Static IP Information
Fill in the required fields:
-
IP address: the fixed address you selected earlier
-
Subnet mask: usually
255.255.255.0 -
Default gateway: the router’s IP address, often something like
192.168.1.1
Then click OK.
You may also want to configure DNS servers at this point for better control over name resolution, though the original text focuses mainly on IP, subnet mask, and gateway.
Step 7: Finish and Confirm
If the settings are correct, Windows will apply them and the network connection should remain active.
You have now successfully configured a static IP address on your Windows computer.
Recommended Example of Static IP Values
Here is a common example for a home network:
-
Router IP / Default Gateway:
192.168.1.1 -
Static IP for PC:
192.168.1.50 -
Subnet Mask:
255.255.255.0
If you choose an address outside your router’s subnet, the connection will fail. Also avoid choosing an address already used by another device, because that can cause IP conflicts.
Why Set a Static IP?
A static IP is useful when:
-
you want stable access to a device over the network,
-
you use port forwarding,
-
you host local services,
-
you need consistent printer or NAS discovery,
-
you want simpler remote management,
-
you are troubleshooting network issues and want fixed addressing.
Compared with automatic DHCP addressing, a static IP gives you consistency and makes advanced networking tasks much easier.
Troubleshooting Tips
If the PC loses internet access after setting a static IP, check the following:
1. Wrong Default Gateway
Make sure the gateway matches the router’s actual IP address.
2. IP Conflict
Make sure no other device is already using the same IP.
3. Wrong Subnet Mask
For most home networks this should be 255.255.255.0.
4. Wrong Adapter
Confirm you changed the correct network adapter, especially if your PC has both Wi-Fi and Ethernet.
5. DNS Not Set Properly
If websites do not load but the router is reachable, DNS may be the problem.
6. Router Reservation and Windows Value Do Not Match
The reserved IP in the router and the manually configured IP on Windows should be the same.
Final Result
By following both parts of the process, you create a more reliable network setup:
-
The router reserves a fixed address for the PC.
-
The Windows PC is manually configured to use that same address.
This gives you a stable, predictable connection on your D-LINK DSL-5300 network and makes future network management easier.
