How to Change a Wi-Fi Router's IP Address: 3 Proven Methods and Troubleshooting

By default, most routers use standard IP addresses like 192.168.0.1 or 192.168.1.1, which creates conflicts on the local network when connecting a second router or establishing a bridged connection. Changing the router's IP address may also be necessary to enhance security, optimize traffic, or integrate with corporate networks that use non-standard subnets.

Changing your IP address isn't as complicated as it seems, but it does require an understanding of basic networking principles. Errors during configuration can lead to loss of access to the web interface or conflicts with other devices. In this article, we'll cover the process. Three main methods for changing your IP address (via the web interface, Telnet/SSH, and mobile app), we'll explain how to choose the right new address and warn you against common mistakes. We'll pay special attention to the settings. DHCP servers, without correcting which, changing the IP can disrupt the operation of the entire network.

If you've never accessed your router's control panel, don't be alarmed: modern interfaces from TP-Link, ASUS or Keenetic are intuitive. The main thing is write down current settings Before making any changes, follow the instructions step by step. For experienced users, we've prepared a section with console configuration, allowing you to flexibly manage network settings, including the subnet mask and gateway.

1. Preparing to change your IP address: what you need to know

Before you start changing your IP, make sure that the new address does not conflict with other devices on the network. For example, if your provider uses addresses like 192.168.100.*, do not assign to the router 192.168.100.1 - This may lead to routing loops.

Basic rules for choosing a new IP:

• 🔹 The address must belong to private range: 192.168.0.0–192.168.255.255, 172.16.0.0–172.31.255.255 or 10.0.0.0–10.255.255.255.
• 🔹 The last two digits (for example, ..1.1) must not match the addresses of other routers in the network.
• 🔹 Avoid addresses ending in .0 or .255 - they are reserved for network and broadcast messages.
• 🔹 If there is already a DHCP server on the network (for example, from your ISP), select the address outside his pool (For example, 192.168.1.250).

Also check if your router supports changing the IP address via the web interface. Some budget models (for example, D-Link DIR-300 (old revisions) this option may be blocked. In this case, you will need to flash it with alternative software like DD-WRT or OpenWRT.

⚠️ Attention: If your router is rented from a provider (for example, Rostelecom or Beeline), changing your IP address may disrupt IPTV or phone services. Check your personal account or contact support for any restrictions.

2. Method 1: Changing the IP via the router's web interface

This is the simplest and safest method, suitable for 90% of users. The instructions are universal for most brands, but the settings path may vary slightly.

Step 1: Login to the Control Panel

• 🖥️ Connect to the router via cable or Wi-Fi.
• 🌐 Open your browser and enter your router's current IP address (usually found on a sticker on the bottom). For example: http://192.168.0.1.
• 🔑 Enter your login and password (by default it is often admin/admin or admin/empty).

Step 2: Find the network settings section

Depending on your router model, look for one of the following menu items:

• 📌 Network → LAN (TP-Link, ASUS)
• 📌 Home Network → IP Settings (Keenetic)
• 📌 Advanced → LAN Setup (Netis, D-Link)

Step 3: Changing the IP address

In the field IP Address (or Local IP address) enter a new address, for example 192.168.45.1Save the changes and the router will reboot.

Check that the new IP does not match the addresses of other devices|

Make sure the subnet mask remains 255.255.255.0 (if you are not sure, do not change)|

Check the box "Apply settings" or "Save"|

Prepare for your router to automatically reboot (your internet connection will be temporarily disconnected) -->

A critical detail: after changing your IP address, you'll need to connect to the router using the new address. If you make a mistake and lose access, reset the settings using the reset button. Reset (hold for 10-15 seconds).

3. Method 2: Configuration via Telnet or SSH (for experienced users)

This method is suitable for advanced users who want flexible network configuration, including a subnet mask, default gateway, or multiple IP addresses on a single interface. It's also useful if the router's web interface is limited (for example, on ISP-branded routers).

Step 1: Enabling Telnet/SSH access

Remote access is disabled by default. To enable it:

• 🔧 Log into your router's web interface.
• 🔍 Find the section Administration → Management.
• 🔄 Enable options Telnet or SSH (sometimes they are hidden in "Advanced settings").
• 🔐 Set the port (usually 22 for SSH or 23 for Telnet).

Step 2: Connecting to the Router

Use the terminal (Windows: PuTTY or cmd; Linux/macOS: built-in terminal). Connection commands:

telnet 192.168.0.1
or for SSH:
ssh admin@192.168.0.1

Enter login/password (the same as for the web interface).

Step 3. Changing IP via console

Commands depend on the router firmware. Examples for popular systems:

• 📡 OpenWRT/LEDE:

  uci set network.lan.ipaddr='192.168.45.1'
  uci commit
  /etc/init.d/network restart

• 📡 DD-WRT:

  nvram set lan_ipaddr="192.168.45.1"
  nvram commit
  reboot

• 📡 ASUS stock firmware:

  ip addr change 192.168.45.1/24 dev br0

⚠️ Warning: Incorrect console commands can brick your router. If you're unsure of the syntax, use the web interface or the official documentation for your model.

What should I do if my router stops responding after receiving commands?

If you lose access to the console after changing your IP, try:

1. Connect to a new IP (for example, 192.168.45.1).

2. If it doesn’t help, reset the settings using the button Reset.

3. For models with recovery support (eg. ASUS) use the utility Firmware Restoration in emergency firmware mode.

4. Method 3: Changing IP via a mobile app

Manufacturers like TP-Link (Tether), ASUS (ASUS Router) or Keenetic (Keenetic) offer mobile apps for managing routers. This is convenient if you need to quickly change settings from your smartphone.

Instructions for the TP-Link Tether app:

1. 📱 Install the app from App Store or Google Play.
2. 🔗 Connect to the router's Wi-Fi network.
3. 🔧 Go to the section Advanced → Network → LAN Settings.
4. 📝 In the field IP address Enter a new address (for example, 192.168.50.1).
5. 💾 Save the changes and wait for the reboot.

Mobile app limitations:

• ❌ Not all models support changing IP via the app (for example, older ones Zyxel Keenetic).
• ❌ No access to advanced settings (subnet mask, DHCP relay).
• ❌ If you make an input error, the application may freeze—you'll have to reconnect.

If your router does not support the official app, use universal utilities like WiFi Analyzer (for monitoring only) or Fing (for network scanning).

5. Configuring a DHCP server after changing IP

Changing the router's IP address does not automatically update the settings. DHCP servers — a system that assigns addresses to devices on the network. If you leave old settings, devices may receive incorrect settings and lose internet access.

What you need to check:

1. Range of distributed addresses: must belong to the same subnet as the router's new IP. For example, if the router now has an address 192.168.45.1, the DHCP range can be 192.168.45.100–192.168.45.200.
2. Default Gateway: must match the new IP of the router.
3. DNS servers: if you use third-party DNS (for example, 8.8.8.8), make sure they do not conflict with local addresses.

Example of DHCP setup on an ASUS router:

After making changes, reconnect all devices to Wi-Fi or update the IP manually (in Windows: ipconfig /release → ipconfig /renew).

6. Typical mistakes and their solutions

Even if you follow the instructions, you may encounter problems. Let's look at the most common ones:

Error 1: Lost access to the web interface

• 🔍 Cause: The new IP was entered incorrectly or conflicts with another device.
• 🛠️ Solution:
  1. Check your cable connection (Wi-Fi may not work due to a DHCP failure).
  2. Use the command ping 192.168.45.1 (replace with your new IP) to make sure the router is responding.
  3. If there is a ping, but the web interface does not open, clear the browser cache or try another one (for example, Firefox instead of Chrome).

Error 2: Devices do not receive an IP address (no internet)

• 🔍 Cause: The DHCP range is configured incorrectly or the DHCP server is disabled.
• 🛠️ Solution:
  1. Connect to the router via cable and manually assign yourself an IP from the new subnet (for example, 192.168.45.2).
  2. Go to the web interface and check the DHCP settings (section LAN or DHCP).
  3. Make sure the option is Enable DHCP Server included.

Error 3: IP conflict with another router

• 🔍 Cause: There is already a device with the same IP on the network (for example, a second router in repeater mode).
• 🛠️ Solution:
  1. Turn off all routers except the one you are configuring.
  2. Use the utility Advanced IP Scanner to search for conflicting addresses.
  3. Change the IP to a free one (for example, with 192.168.1.1 on 192.168.2.1).

⚠️ Attention: If your router is operating in the Bridge (bridge) or Repeater (repeater), changing the IP address may interrupt the connection to the primary router. In such cases, configure the primary router first, then the dependent devices.

7. Additional settings: subnet mask, gateway, DNS

Advanced users or specific tasks (such as combining multiple subnets) may require adjusting additional parameters.

Subnet mask (Subnet Mask)

The default is 255.255.255.0, which allows you to connect up to 254 devices. If you need more addresses, you can use:

• 255.255.254.0 — 510 devices (range X.Y.0.1–X.Y.1.254).
• 255.255.252.0 — 1022 devices.

But remember: changing the mask requires reconfiguration of all devices on the network!

Default Gateway (Default Gateway)

Typically, this is the same as the router's IP address. If you have additional routers on your network (for example, for a guest network), enter their IP addresses in the field. Static Route or Gateway.

DNS servers

By default, the router uses the provider's DNS, but you can specify alternative ones:

• 🌍 8.8.8.8 And 8.8.4.4 — Google Public DNS.
• 🌍 1.1.1.1 — Cloudflare DNS (fast and secure).
• 🌍 77.88.8.8 — Yandex DNS (optimized for RuNet).

To change DNS on a router Keenetic:

1. Go to Internet → DNS servers.
2. Mark Use the following DNS servers.
3. Enter the required addresses and save.

8. Checking functionality after changes

After changing your router's IP address, perform the following checks to ensure your network is working properly:

Step 1: Checking access to the web interface

• 🖥️ Connect to the router using a new IP (for example, http://192.168.45.1).
• 🔑 Make sure your login/password is working.

Step 2: Testing your Internet connection

• 🌐 Open your browser and check if any website is loading (for example, ya.ru).
• 📡 Use the command ping 8.8.8.8 to check connection with external servers.

Step 3: Check DHCP

• 📱 Connect a new device (e.g. smartphone) to Wi-Fi.
• 🔍 Make sure it automatically gets an IP from the new range (on Android: Settings → Wi-Fi → [Your network] → Find IP).

Step 4. Conflict diagnostics

• 🛠️ Use the utility Advanced IP Scanner to scan the network for duplicate IPs.
• 📊 Check your router log (System Tools → Journal) for DHCP errors.

If all tests pass, setup is complete. If you encounter any issues, return to the ["Typical Errors"](#errors) section or reset the router to factory settings.

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

Is it possible to change a router's IP address from a phone without a computer?

Yes, if your router supports the official mobile app (for example, TP-Link Tether or ASUS Router). Alternatively, you can use a browser on your smartphone to access the web interface, but this is less convenient due to the interface being adapted for mobile screens.

Universal utilities like Network Analyzer, but they will not replace a full-fledged web interface.

What happens if I assign a router an IP from a public range (for example, 8.8.8.8)?

This will lead to serious problems:

• 🚫 Local devices will not be able to connect to the router.
• 🚫 Traffic will go directly to the Internet, bypassing NAT, which is unsafe.
• 🚫 Your provider may block your address for suspicious activity.

Use only private ranges: 192.168.x.x, 172.16.x.x–172.31.x.x or 10.x.x.x.

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

There are three ways:

1. Reset via button Reset: Hold it for 10-15 seconds until the indicators flash. The router will return to factory settings.
2. Connecting via the old IP: If the router responds to ping at the new address, but the web interface does not open, try connecting via http://[new_IP] in another browser.
3. Setting up a static IP on a PC: Manually assign yourself an IP from the old subnet (for example, 192.168.0.2) and try to access the router via 192.168.0.1.

Should I change my router's IP address to improve security?
Changing the default IP (for example, from 192.168.0.1 on 192.168.45.1) slightly increases safety, as it complicates automated attacks on the web interface. However, this does not protect against:
• 🔓 Vulnerabilities in router firmware.
• 🔓 Attacks through Wi-Fi vulnerabilities (for example, KRACK).
• 🔓 Phishing (if the attacker knows the new IP).
For real protection:
• 🔒 Update your router firmware.
• 🔒 Disable remote administration (section Administration → Remote Management).
• 🔒 Use a strong password for Wi-Fi (standard WPA3).
Is it possible to assign two IP addresses to a router?

Yes, some firmware (for example, DD-WRT or OpenWRT) support the assignment of multiple IPs to one interface (alias). This is useful for:

• 📡 Organizing multiple subnets on a single router.
• 📡 Traffic separation (for example, for IPTV and the Internet).

Example command for OpenWRT:

uci set network.lan.ipalias='192.168.2.1/24'
uci commit
/etc/init.d/network restart

Please note: Not all routers support this feature on stock firmware.
