How to Change a Wi-Fi Router's IP Address: 3 Proven Methods (2026)

Change Router IP addresses — a problem faced by both novice users and experienced home network administrators. The reasons for this can vary, from a trivial address conflict with another device to the need to improve network security or optimize local services. For example, if your router uses 192.168.0.1, and the provider gives the devices a range 192.168.1.x, without changing the IP, connection problems cannot be avoided.

In this article, we will look at three main methods of changing your IP address: router web interface, using mobile application manufacturer and manually through Telnet/SSH (for advanced users). You will also learn how to set it up correctly. DHCP serverTo avoid future conflicts, and what to do if the router stops responding after changing the address. Important: The procedure varies depending on the device model—instructions are provided for popular brands: TP-Link, ASUS, Keenetic, MikroTik And Zyxel.

Before you begin, make sure you have access to your router settings (username and password for the admin panel). If you've forgotten them, you'll first need to perform a factory reset—we'll cover this at the end of the article.

1. Why change the router's IP address?

At first glance, a standard IP address seems to be 192.168.1.1 or 192.168.0.1 Satisfies most users. However, there are situations when changing it becomes necessary:

• 🔄 Address conflict — if there is already a device with the same IP address on the network (for example, a second router or a provider modem).
• 🔒 Security — standard addresses (192.168.1.1, 192.168.0.1) are known to hackers, and changing them makes unauthorized access more difficult.
• 📡 Network optimization - to separate traffic (for example, allocating a separate subnet for IoT devices or guest Wi-Fi).
• 🔧 Technical requirements - Some providers or corporate policies require the use of specific ranges.

Additionally, changing the IP may be required during setup. VPN servers on the router, connection IP cameras or organizations local file storage (NAS). For example, if you use Synology DiskStation or QNAPChanging the router's IP address will help avoid conflicts with the NAS device.

⚠️ Attention: If you change the IP address of the router, which is issued by the provider (for example, when connecting via PPPoE or DHCP), this will not affect your "white" external IP. This is only about local address in the home network.

2. Preparing to change your IP address

Before you begin setting up, please complete a few mandatory steps:

1. Check the current IP address of the router. This can be done via the command line (ipconfig in Windows or ifconfig in macOS/Linux) or by looking at the sticker on the back of the device.
2. Connect to the router via cable. Using Wi-Fi while changing network settings may result in loss of connection.
3. Write down the current settings. Take photos or save screenshots of sections LAN, DHCP And WAN - this will help you get everything back in case of an error.
4. Select a new IP address. It must belong to the same subnet as the old one (for example, if it was 192.168.1.1, there may be a new one 192.168.1.254), but not conflict with other devices.

Also make sure you know login and password From the router's admin panel. If you haven't changed them, try the standard combinations:

If you have forgotten your password, do not try to guess it, as this may lock your device. Instead, follow these steps: factory reset (button Reset on the back panel, hold for 10-15 seconds).

3. Method 1: Changing IP via the web interface

The simplest and most universal method is to use web interface router. This manual is suitable for most modern devices, but the menus may differ slightly.

For routers TP-Link And ASUS:

1. Open your browser and enter your router's current IP address (e.g. 192.168.1.1).
2. Log in using your username and password.
3. Go to the section Network → LAN (TP-Link) or Local Network → IP Address (ASUS).
4. In the field IP address Enter a new address (for example, 192.168.42.1).
5. Save the changes. The router will reboot, and you'll need to connect to it using the new IP address.

For routers Keenetic:

1. Go to the web interface at my.keenetic.net or current IP.
2. Go to System → Network Settings → Interfaces.
3. Select interface Home (or another one if you use multiple networks).
4. In the field IP address Enter the new address and save.

For routers Zyxel:

1. Open the section Network → Interfaces → LAN.
2. In the block IP settings Change the address to the desired one.
3. Click Apply and confirm the reboot.

After changing your IP address, you will need to update the connection settings on all devices on the network. For example, if you changed the address from 192.168.1.1 on 192.168.42.1, then to access the admin panel you now need to enter a new address.

4. Method 2: Using a mobile app

Many manufacturers offer official apps for managing routers from a smartphone. This is convenient if you don't have access to a computer. Let's look at the process using popular apps as an example.

Application TP-Link Tether:

1. Download and install the application from App Store or Google Play.
2. Connect to your router's Wi-Fi network.
3. Open the application and log in.
4. Go to Advanced → Network → LAN Settings.
5. Change the IP address in the appropriate field and save.

Application ASUS Router:

1. In the main menu of the application, select your router.
2. Go to Local Network → IP Address.
3. Enter the new address and confirm the changes.

Application Keenetic:

1. Open the section System → Network Settings.
2. Select interface Home and change the IP.
3. Save and wait for reboot.

Mobile apps are usually easier to use than the web interface, but their functionality may be limited. For example, TP-Link Tether there is no possibility to configure DHCP reservation, which is sometimes required when changing IP.

⚠️ Attention: If you use an app to manage your router via the cloud (for example, Keenetic Cloud), after changing the IP address, access to the old address will be lost. Make sure you have an alternative connection method (e.g., cable).

5. Method 3: Changing IP via Telnet/SSH (for advanced users)

This method is suitable for advanced users and administrators who manage routers based on OpenWRT, DD-WRT or MikroTik RouterOSIt requires knowledge of the command line and may cause the device to malfunction if errors occur.

For routers on OpenWRT/DD-WRT:

1. Connect to the router via SSH (use PuTTY for Windows or terminal in macOS/Linux).
2. Enter the command to edit the configuration file:

   vi /etc/config/network

3. Find the block with interface settings lan and change the line option ipaddr:

   option ipaddr '192.168.42.1'

4. Save changes (:wq V vi) and reboot the router:

   reboot

For routers MikroTik:

1. Connect via WinBox or SSH.
2. Run the command to change IP:

   /ip address set [find interface="ether1"] address=192.168.42.1/24

   (replace ether1 to your interface and 192.168.42.1/24 to the required address with subnet mask).

3. Check the changes:

   /ip address print

After applying the changes, don't forget to refresh the settings. DHCP serversso that it issues addresses from the new subnet. For example, in OpenWRT This is done through a file /etc/config/dhcp.

What should I do if my router stops responding after changing its IP address?

If you lose access to your router after changing your IP address:

1. Connect to it via cable and check if the new IP conflicts with another device (for example, another router or modem).

2. Try resetting the DNS cache on your computer: in Windows, run ipconfig /flushdns, in macOS/Linux — sudo dscacheutil -flushcache.

3. If the router does not respond at all, perform a factory reset (button Reset for 10–15 seconds).

4. Make sure that the new IP address is in the same subnet as the old one (for example, if it was 192.168.1.1/24, the new one should be in the range 192.168.1.x).

6. Configuring DHCP after changing IP

Changing your router's IP address almost always requires adjusting the settings. DHCP servers — a service that automatically assigns addresses to devices on the network. Failure to do so could result in devices losing access to the internet or local resources.

How to set up DHCP:

1. Log into the router's web interface using the new IP address.
2. Find the section DHCP (usually on the menu Net or Local area network).
3. Make sure that DHCP server is enabled.
4. Set up address pool so that it does not overlap with the router's new IP address. For example, if the router now has the address 192.168.42.1, the pool can be defined as 192.168.42.100–192.168.42.200.
5. Save the settings and reboot the router.

It is also recommended to reserve IP addresses for important devices (for example, for NAS, printers or IP cameras). This is done in the section DHCP reservation or IP to MAC Binding.

⚠️ Attention: If you use double NAT (for example, the router is connected to the provider's modem, which also distributes IP), after changing the router's address, it may be necessary to reconfigure the ports (Port Forwarding) to access local services from the Internet.

7. Common mistakes and their solutions

When changing a router's IP address, users often encounter common problems. Let's look at the most common ones and how to resolve them.

Error 1: The router does not respond to the new IP address.

Cause: The new address conflicts with another device on the network or is on a different subnet.

Solution:

• 🔍 Check if this IP is in use by another device (command arp -a in Windows).
• 🔄 Restore your old IP address by resetting the settings (button Reset).
• 📡 Make sure the new IP is in the same subnet (for example, if the mask 255.255.255.0, the first three octets must match).

Error 2: No Internet Access After IP Change

Cause: Incorrect settings WAN or DHCP.

Solution:

• 🌐 Check your ISP connection settings (PPPoE, DHCP, Static IP).
• 🔧 Make sure that default gateway And DNS servers configured correctly.
• 🔄 Restart your router and provider modem.

Error 3: Devices do not receive IP addresses automatically

Cause: The DHCP server is disabled or incorrectly configured.

Solution:

• ⚙️ Go to Settings DHCP and turn on the server.
• 📋 Check that the address pool does not overlap with the router's IP.
• 🔄 Reconnect your devices to Wi-Fi.

If the problem is not solved, try reset the router to factory settings and repeat the IP change procedure from the beginning. It's also a good idea to update your device's firmware—sometimes errors are caused by bugs in the older software version.

8. Additional safety tips

Changing your router's IP address is a good reason to think about your network's security. Here are some recommendations to help make it more secure:

• 🔐 Change the default password for the admin panel. Use a complex combination of letters, numbers and symbols.
• 🛡️ Disable remote access to the router (if you're not using one). This will reduce the risk of hacking.
• 🔄 Update the firmware to the latest version - manufacturers regularly patch vulnerabilities.
• 📋 Set up a guest network for visitors to isolate them from the main network.
• 🔍 Enable the firewall and disable unnecessary services (for example, UPnP, if you don't use it).

It is also worth considering the possibility of using non-standard subnetFor example, instead of the popular 192.168.1.x you can choose 10.0.0.x or 172.16.0.xThis won't make your network impenetrable, but it will make life more difficult for automated scanners looking for vulnerable devices.

If you are using a router in an office or small business, consider setting it up VLAN (virtual local area networks). This will allow you to separate traffic from different departments or device types, improving both security and network performance.

FAQ: Answers to Frequently Asked Questions

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

Yes, if your router has a mobile app (eg. TP-Link Tether, ASUS Router or Keenetic). You can also use your smartphone's browser to access the web interface using your current IP address.

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

This will lead to address conflict, which can cause both devices to become unavailable and the network to stop functioning properly. In some cases, this can lead to a complete loss of connection.

How do I get my old IP address back if the new one isn't working?

If you have lost access to your router, please follow these steps: hard reset (button Reset for 10-15 seconds). After this, the device will return to factory settings, including the default IP address.

Do I need to change my IP address if I only have one router?

Not necessarily. Changing the IP is only necessary in case of conflicts, security issues, or specific network requirements. For most home users, the standard address (192.168.1.1 or 192.168.0.1) fits perfectly.

Can I use any IP address for my router?

No. The IP address must belong to one of private subnets:

• 192.168.0.0 – 192.168.255.255 (mask 255.255.255.0)
• 172.16.0.0 – 172.31.255.255 (mask 255.255.0.0)
• 10.0.0.0 – 10.255.255.255 (mask 255.0.0.0)

Using public ("white") addresses in a local network is not allowed.
