How to Change a Wi-Fi Router's IP Address: A Step-by-Step Guide with Examples

Changing a router's IP address is a common task for both novice users and experienced home network administrators. This is most often required to resolve address conflicts within the local network, improve security, or optimize the operation of multiple routers. However, incorrect actions can result in loss of access to the device or internet disruptions.

In this article, we will take a detailed look at why you might need to change your router's address, what IP address options exist, and how to perform the procedure on popular models from TP-Link, ASUS, Keenetic, Xiaomi and other manufacturers. We'll pay special attention to common errors and troubleshooting steps so you can confidently set up your network without the risk of losing your internet connection.

Why change the Wi-Fi router address?

By default, most routers use standard IP addresses like 192.168.0.1 or 192.168.1.1In some cases, changing them becomes necessary:

• 🔄 Address conflict — if there are two devices with the same IP address on the network (for example, the main and additional routers).
• 🔒 Security — standard addresses are easier for attackers to guess to attack the network.
• 📡 Network optimization — when setting up multiple routers in one local network (for example, to create a mesh system).
• 🛠️ Technical requirements — Some providers or corporate policies impose special conditions on addressing.

It is important to understand that changing the IP address of the router does not affect internet speed or Wi-Fi coverage. This is a purely network-related setting that only affects device management. If your goal is to improve signal strength or connection stability, consider other parameters, such as Wi-Fi channel selection or firmware updates.

What IP address can be used for a router?

When choosing a new address for your router, it is important to follow the rules private networks, defined by the standard RFC 1918These addresses are not routable on the global Internet and are intended for local use only. Available ranges:

• 📌 10.0.0.0 — 10.255.255.255 (class A, suitable for large networks).
• 📌 172.16.0.0 — 172.31.255.255 (class B, medium networks).
• 📌 192.168.0.0 — 192.168.255.255 (class C, most common for home routers).

For a home network, addresses from the last range are usually selected, for example: 192.168.10.1, 192.168.50.1 or 192.168.100.1The main rule: the first three octets (numbers before the last dot) must match for the router and all devices on the network, and last octet the router is usually equal 1 (For example, 192.168.X.1).

⚠️ Warning: Do not use addresses that are already occupied by other devices on your network (e.g. 192.168.1.1(if another router is already using it). This will cause a conflict and loss of access to both devices.

Preparing to change the router address

Before changing your IP address, take a few important steps to avoid losing access to your device:

Back up your current router settings | Write down your current IP address, username, and password | Connect to your router via cable (recommended) | Make sure there are no active internet connections (e.g., downloads) | Make sure you have access to another device for diagnostics (smartphone, laptop)

-->

If you are connected to the router via Wi-Fi, It is recommended to switch to a wired connection (through LAN-port). This is because changing the IP address can break the Wi-Fi connection, and you'll lose access to the web interface. Also, check that your computer or smartphone Automatic IP acquisition is disabled (configure static IP manually if necessary).

If you don't remember your router's current address, you can find it out in several ways:

• 🖥️ On Windows: open command prompt (Win + R → enter cmd → ipconfig) and find the line Main gateway.
• 🍎 On MacOS: go to System Preferences → Network → Advanced → TCP/IP.
• 📱 On Android/iOS: use apps like Fing or WiFi Analyzer.

⚠️ Attention: If you are using a router from a provider (for example, Rostelecom, Beeline, MTS), some settings may be locked. In this case, please contact support or check if there is a mode Bridge (bridge) that will allow you to use your own router.

Step-by-step instructions: how to change your router's IP address

The process of changing the address varies little between router models, but there are some nuances depending on the firmware. Let's look at the general algorithm and specific features for popular brands.

Universal method (for most routers)

1. Open the router's web interface by entering the current IP address in the browser's address bar (e.g. 192.168.0.1 or 192.168.1.1).

2. Log in using your login and password (by default, it is often admin/admin or indicated on the device sticker).

3. Go to the local network settings section. This is usually called:

• 📡 LAN or Local Network (at TP-Link, ASUS).
• 🌐 Net → Local area network (at Keenetic).
• 🔧 Advanced → Network → LAN (at Netgear).

4. Find the field IP Address (or Router address) and enter a new address, for example, 192.168.10.1.

5. Save the settings. The router will reboot, and you'll need to connect to it using the new address.

Features for popular brands

TP-Link (Archer, TL-WR, Deco):

Go to Advanced → Network → LANIn the field IP Address Please enter a new address. For models with firmware TP-Link OneMesh additional confirmation may be required.

ASUS (RT-AX, RT-AC, ZenWiFi):

Open Local Area Network (LAN) in the side menu. Field Router IP address available for editing. On some models (for example, RT-AX88U) there is an option DHCP server, which should also be adjusted to the new range.

Keenetic (Giga, Hero, Viva):

In the interface KeeneticOS go to Network → Segments → Home NetworkHere you can change the address in the block. IPv4 settingsPlease note that on Keenetic there is also an option Opening hours - if the router is used as a repeater, IP changing may be limited.

Xiaomi (Mi Router, AIoT Router):

In the mobile app Mi Wi-Fi or open the web interface Settings → Local Network. Field Router IP address Available for editing, but after changing it you will need to re-authorize.

What to do if the new address does not open?

If you cannot access the web interface after changing your IP address:

1. Check that you are connected to the router via cable or the correct Wi-Fi.

2. Make sure that your computer does not have a static IP address from the old range (configure automatic IP acquisition or manually enter a new address from the same subnet, for example, 192.168.10.100 if the router is now 192.168.10.1).

3. Try flushing your DNS cache or using a different browser.

4. If nothing helps, reset the router to factory settings (using the button Reset) and configure it again.

Common mistakes and how to avoid them

Even experienced users sometimes make mistakes when changing their router's IP address. Here are the most common ones and how to fix them:

• 🚫 Conflict with another device If the new IP address is already in use on the network (for example, by another router or server), you won't be able to connect. Check for occupied addresses using the utility arp -a (Windows) or nmap (Linux/Mac).
• 🔌 Invalid subnet mask - if you changed the IP, but forgot to update the mask (for example, with 255.255.255.0 on 255.255.0.0), devices will not be able to communicate. The mask must match the selected range.
• 🔄 Unsaved DHCP settings - if you changed the router's IP address but did not update the address distribution range in the settings DHCP, devices will not receive the correct network parameters. For example, if the router is now 192.168.10.1, then the DHCP pool should be something like 192.168.10.100–192.168.10.200.
• 📵 Loss of access after change If you're connected via Wi-Fi and the router reboots, the connection may be lost. Always use a wired connection for such changes.

Critical error: If you have changed the router's IP address to a value outside of private networks (e.g. 8.8.8.1 or 1.1.1.1), the device will become unavailable because these addresses are routed to the internet. The only way to fix this is a factory reset.

⚠️ Attention: On some routers (for example, Zyxel Keenetic with firmware NDMSChanging your IP address may reset additional settings, such as static routes or firewall rules. Before making changes, export the configuration to a file.

How can I get my old address back if something goes wrong?

If you lose access to your router after changing your IP address, don't panic. There are several ways to restore functionality:

1. Check the physical connection - Make sure the cable is connected to LAN-port (not to WAN!), and the indicators on the router are green.
2. Flush your DNS cache - on Windows run in command line:

   ipconfig /release
   ipconfig /renew
   ipconfig /flushdns

   On MacOS/Linux use sudo dscacheutil -flushcache or sudo systemd-resolve --flush-caches.

3. Set up a static IP on your computer - if the router now has an address 192.168.10.1, give the computer an IP from the same subnet, for example, 192.168.10.100 with a mask 255.255.255.0.
4. Use the recovery utility - some manufacturers (for example, ASUS) offer utilities like Firmware Restoration, which allow you to regain access even without a reset.
5. Factory reset - If nothing helps, press and hold the button Reset (usually located on the rear panel) for 10-15 seconds. After this, the router will return to the default IP (indicated on the sticker).

If you reset your router, you'll need to reconfigure it: enter your internet connection settings (from your provider), configure Wi-Fi, and configure security. To avoid this in the future, Always make a backup copy of your configuration before changing critical parameters.

Additional settings after changing the IP address

Changing a router's IP address often requires adjusting related settings. Here's what to check and configure after a successful change:

• 🔄 DHCP range — update the pool of distributed addresses to match the new subnet. For example, if the router is now 192.168.20.1, set the range with 192.168.20.100 to 192.168.20.200.
• 📡 Static routes - If you use them to communicate with other subnets, update the gateways and interfaces.
• 🔒 Firewall Rules - some rules may be linked to the old IP address.
• 🖥️ Port Forwarding — If you use port forwarding for game servers, cameras, or other services, update your internal IP addresses.
• 📱 Connected devices — Some gadgets (such as smart speakers or IP cameras) may require reconnection.

If you have configured access to the router from the Internet (through DDNS (or port forwarding), don't forget to update these settings, as the external address may have changed. Also, check the operation UPnP - If enabled, it can automatically update rules, but sometimes requires a manual reboot.

On routers with support Mesh networks (For example, TP-Link Deco or ASUS AiMesh) Changing the IP address of the main node may require reconnecting additional access points. In this case, monitor the LEDs on the devices—they should be steady (usually blue or green).

FAQ: Frequently asked questions about changing your router's IP address

Is it possible to change the router's IP address from a phone?

Yes, but it's less secure than using a computer. Use the manufacturer's official app (for example, TP-Link Tether, ASUS Router or Mi Wi-Fi). The main risk is losing connection while saving settings. If this happens, connect to the router via cable or reset the settings.

What happens if two routers on a network have the same IP address?

This will lead to IP conflictBoth devices will become unavailable, and the network will stop functioning correctly. Symptoms include no internet connection, inability to access the web interface, and connection errors. The solution is to change the IP address of one of the routers or disconnect one of the devices.

How do I know which IP address is free to use?

Use network scanning utilities:

• On Windows: arp -a (shows ARP cache with active devices).
• On Linux/Mac: nmap -sn 192.168.1.0/24 (scans the specified subnet).
• Mobile applications: Fing, Network Scanner.

Select an address that does not appear in the scan results.

Should I change my router's IP address to improve security?

Changing the default address (for example, from 192.168.0.1 on 192.168.25.1) will make things a little more difficult for attackers, but is not a reliable protectionFor safety, it is more important:

• Use a complex password to access the web interface.
• Disable remote control (if not needed).
• Update the router firmware.
• Turn firewall on and off UPnP, if it is not needed.

Is it possible to use a public IP address for a router?

No, this will cause the network to become unusable. Public IP addresses (e.g. 8.8.8.8 or 94.100.18.1) are routed to the internet and cannot be used on the local network. The router will become unavailable, and the only way to fix this is a factory reset.
