A static IP address keeps the same network address assigned to your device, making it easier to support services such as remote access, port forwarding, network printers, and shared devices. Setting it up correctly helps maintain reliable connectivity, while incorrect settings can cause network access issues.

DHCP Reservation (Recommended)

DHCP reservation is the simplest and safest option because the router automatically assigns the same IP address to your device every time it connects.

1. Open a web browser and enter your router's IP address (for example, 192.168.1.1).
2. Sign in using your router administrator credentials.
3. Navigate to LAN Settings, DHCP Settings, Address Reservation, or a similarly named section.
4. Locate your device in the list of connected devices.
5. Assign a reserved IP address (for example, 192.168.1.50).
6. Save or apply the changes.
7. Restart the device to ensure the reservation is applied.

Manual Static IP Configuration

Use this method when DHCP reservation is unavailable or when a device requires a manually configured address.

1. Open your device's network settings:
   • Windows: Settings > Network & Internet > Change adapter options
   • Mac: System Settings > Network
   • Mobile Devices: Wi-Fi > Select Network > Advanced Settings
2. Select the active network connection (Wi-Fi or Ethernet).
3. Change the IP assignment setting from Automatic (DHCP) to Manual or Static.
4. Enter the required network information:
   • IP Address: Example: 192.168.1.50
   • Subnet Mask: Example: 255.255.255.0
   • Default Gateway: Example: 192.168.1.1
   • DNS Server: Example: 8.8.8.8 or 1.1.1.1
5. Save the configuration.
6. Disconnect and reconnect to the network.
7. Confirm connectivity by opening a website or running a ping test.

Optional: Verify the Assigned IP Address

1. Open Command Prompt (Windows) or Terminal (Mac/Linux).
2. Run the appropriate command:
   • Windows: ipconfig
   • Mac/Linux: ifconfig or ip a
3. Verify that the displayed IP address matches the one you assigned.

If the device cannot connect after configuration, try the following checks:

1. Check for IP Address Conflicts

• Verify that no other device is using the same IP address.
• Review your router's connected device list or use arp -a.

2. Verify Network Information

• Confirm the IP address, subnet mask, gateway, and DNS settings are correct.

3. Test Connectivity

Test communication with the router:

ping 192.168.1.1

Test internet access:

ping 8.8.8.8

Test DNS resolution:

ping google.com

4. Refresh Network Configuration (Windows)

If network settings appear stuck or cached, run:

ipconfig /flushdns
ipconfig /release
ipconfig /renew

5. Restart the Network Adapter

• Disable and then re-enable the network connection.

6. Review Router Configuration

• Ensure the static IP address does not overlap with the router's DHCP address pool.

7. Check Firewall or Security Software

• Temporarily disable security software to determine whether it is blocking network traffic.

8. Update Network Software

• Install the latest router firmware and network adapter drivers.

9. Reset Network Settings

• Restore default network settings if other troubleshooting steps do not resolve the issue.

10. Validate Advanced Network Requirements

• In business or segmented networks, confirm that the correct subnet and VLAN settings are being used.

• Whenever possible, use DHCP reservation instead of manual static IP assignment.
• Choose an IP address outside the router's DHCP range unless the router specifically supports reservations within that range.
• Record your current network settings before making changes.
• A brief network interruption during configuration is normal.
• Incorrect IP, gateway, subnet mask, or DNS settings may prevent internet access.
• Do not manually assign static IP addresses on managed or corporate networks without approval from the network administrator.
• A static IP address does not provide additional security. Continue using strong passwords, firewall protection, and other security controls.
