Changing a router's local IP address is often necessary to resolve network conflicts or improve the security of a home infrastructure. Default values, such as 192.168.0.1, are familiar not only to users but also to potential attackers, making them a target for attacks. Changing this setting makes it more difficult for unauthorized access to the device's control panel.
The procedure doesn't require in-depth knowledge of networking technologies, but it does require caution when entering numerical values. Any addressing error can result in loss of connection to the router, requiring a physical reset. In this guide, we'll discuss safe procedures for equipment from various manufacturers.
Why do I need to change the default gateway address?
The main reason for modifying network settings is local area network architectureIf your ISP provides access via a static IP or uses the same subnet as your router's default, an address conflict occurs. Computers stop seeing the gateway, and the internet connection disappears. In this situation, changing the range to 192.168.XX.1 is the only working solution.
In addition, the change of address serves as an element of the basic perimeter protectionHackers often use automated scanners that check standard ports and addresses of popular router models. By hiding the admin panel behind a non-standard IP address, you reduce the likelihood of a successful automated attack. It's not a panacea, but it is an effective barrier.
There are several scenarios where tampering with gateway settings is justified:
- 🔹 Network merging: When connecting a second router as an access point, it is necessary that their addresses do not overlap.
- 🔹 Provider requirements: Some service providers require a subnet for IPTV or telephony to function correctly.
- 🔹 Organizational policy: Offices often have a standard addressing scheme that differs from factory standards.
⚠️ Please note: After changing your router's IP address, all connected devices may temporarily lose internet access. You will need to reconnect to the network or renew the DHCP lease.
Preparing to change network settings
Before starting work, you need to ensure a stable connection with the device. It is best to use cable connection (Ethernet), as changing the IP address can interrupt the wireless connection at the most inopportune moment. Make sure your laptop or PC is connected to the router's LAN port.
You'll also need to know your current control panel login credentials. If you've never changed them, they'll be on a sticker on the bottom of the case. Typically, it's a combination of admin/admin or admin/passwordWithout this data access to web interface closed.
☑️ Preparing to set up the network
Check the current gateway address via the command line. Enter the command ipconfig (for Windows) or ifconfig (for macOS/Linux) and find the line labeled "Default Gateway." This is the address you'll be changing. Write it down so you know which page to access.
Login to the admin panel
Open any modern browser. In the address bar, not the search bar, enter the router's current IP address. Most often, this is 192.168.0.1 or 192.168.1.1Press Enter. If the page doesn't load, check that automatic IP acquisition is configured correctly on your computer's network card.
The system will ask for authorization. Enter your username and password. After successful login, you will be taken to control panelsInterfaces vary by manufacturer, but the menu layout is similar. Look for sections labeled "Network," "LAN," or "Local Network."
What should I do if the page doesn't open?
If your browser displays "Unable to access the site," try clearing the DNS cache with the ipconfig /flushdns command or using incognito mode. Also, check if your antivirus software is blocking access to local addresses.
In some models, for example, Keenetic or MikroTikThe interface can be more complex. It's important not to get confused by the terminology. Look specifically for the settings. LAN interface, not WAN (which is responsible for the ISP's login). Selecting the wrong section will result in loss of access to the external network.
Instructions for changing IP addresses for different routers
The process for changing the address varies depending on the device's firmware. Below are the steps for the most popular brands. Please note that the router may reboot after applying the settings.
For devices TP-Link (green or blue interface): Go to "Network" → "LAN". In the "IP Address" field, enter the new address, for example, 192.168.88.1Save the changes by clicking the "Save" button. The device will warn you about a reboot.
In routers ASUSIn the left menu, select "Local Area Network" (LAN). In the top tab, make sure you're in the "LAN IP Address" section. Change the value in the "LAN IP Address" field. Click "Apply." The router will overwrite the configuration and require you to log in again using the new address.
| Router brand | Path to the menu | Field for change | Action after the change |
|---|---|---|---|
| TP-Link | Network → LAN | IP Address | Reboot |
| ASUS | Local Area Network → LAN IP | LAN IP address | Apply |
| D-Link | Setup → Local Network | IP Address | Save Settings |
| Keenetic | Home Network → IP Settings | IP address | Save |
Devices D-Link Often there is a menu "Setup" → "Local Network". The IP address can also be changed here. Pay attention to the subnet mask: it usually remains 255.255.255.0Changing it unnecessarily is not recommended, as it may disrupt the network.
Configuring a DHCP server after changing the address
After you have changed the IP address of the router itself, you need to check the settings DHCP serversThis service automatically distributes addresses to all connected devices. The range of distributed addresses must begin after the router's address.
For example, if you have given the router an address 192.168.50.1, then the starting address of the DHCP pool must be 192.168.50.2 or higher. If the range remains old (for example, starting with 192.168.0.100), devices will not be able to obtain the correct gateway and will not be able to access the internet.
- 🔸 Find the "DHCP Server" section in the settings menu.
- 🔸 Make sure the server status is "Enable".
- 🔸 Check the "Start IP Address" and "End IP Address" fields.
⚠️ Note: Router interfaces are constantly being updated. The layout of menu items may differ from that described in the instructions. Always look for sections related to the local area network (LAN).
In some cases, it is useful to reserve a static IP for important devices such as network printers or NAS storageThis is done in the same DHCP section, but in the "Address Reservation" subsection. Binding an address to the device's MAC address ensures that it will always be accessible via the same IP address.
Possible problems and their solutions
The most common issue is losing connection to the router immediately after applying the settings. The computer continues to use the old gateway address, which is now irrelevant. In this case, you need to manually assign a static IP address to the PC's network card within the new subnet range.
To do this, go to "Network Settings" → "Configure Adapter Settings." Select your connection, click "Properties," find "Internet Protocol Version 4 (TCP/IPv4)" and enter the address manually. For example, if the router has become 192.168.77.1, give it to the computer 192.168.77.5After this, you can go back to the settings and restore automatic IP acquisition.
If the router is frozen and does not respond to either the old or the new address, this will help Hard ResetThere's a small hole on the case labeled "Reset." Press it with a paperclip for 10-15 seconds while the power is on. This will reset the device to factory settings and the default IP address.
Can I use any IP address for my router?
No, special ranges are reserved for local networks. Use addresses from the 192.168.xx, 10.xxx, or 172.16.xx - 172.31.xx ranges. Using public addresses will result in routing errors.
What should I do if I forgot my router's new IP address?
Use the command ipconfig In the command line, if the computer is connected and obtains an address automatically. The "Default Gateway" line will show the router's current address. If DHCP is disabled, the only solution is to reset it using the Reset button.
Does changing IP address affect internet speed?
The address itself doesn't affect speed. However, if you incorrectly configure the subnet mask or DNS servers during the change process, your internet may be slow or not work at all. It's important to check all related parameters.
Do I need to change my Wi-Fi password after changing my IP?
This isn't required, but it's recommended as part of a comprehensive security plan. If you're changing your address to protect against hacking, it's also a good idea to use a strong password for your wireless network.
