Changing a WiFi router's IP address is a task faced by both advanced users and novices when expanding their home network. This is most often necessary when combining two routers into a single system, where the default gateway addresses overlap, creating a critical hardware conflict. IP conflict can completely paralyze the local network, making it impossible to access the Internet or manage devices.
In some cases, the default address provided by the manufacturer (e.g. 192.168.0.1 or 192.168.1.1) may already be taken by another device in a complex corporate or office environment. Administrative interface In this situation, the router becomes unavailable, and the only solution is to temporarily change your computer's network settings, which is inconvenient and requires constant monitoring. It's much easier and more effective to reconfigure the router itself.
Changing the address doesn't require advanced programming knowledge, but it does require careful data entry. A single digit error can result in the loss of connection to the device, after which you'll have to perform reset settings to factory defaults. In this article, we'll detail the steps for different hardware models and explore the nuances of setting up static addresses.
Why change the default IP address of the router?
The main reason for IP address changes is the architecture of complex networks. If you connect a second router to the first via a cable (LAN-to-LAN) to increase WiFi coverage, their default gateways often become the same. For example, both devices might have the address 192.168.1.1. In this case, the network loses track of where to send data packets, and a glitch occurs. addressing conflict.
⚠️ Important: Before making any changes to your network settings, make sure you are connected to your router with an Ethernet cable. Changing your WiFi IP address will disconnect your wireless network connection, and you will lose access to your settings before you can save them.
In addition to resolving conflicts, changing the default gateway address is an element of basic cyber hygieneHackers and virus scanners often check the standard ports and addresses of popular router models for hacking attempts. By changing the address to a non-standard one, you make it more difficult for attackers by using the "security through obscurity" method.
Changing the address may also be necessary when configuring specific software or game servers that are tightly bound to a specific subnet. In such cases static IP becomes a mandatory requirement for the correct operation of applications.
Preparing to change network settings
Before modifying the configuration, you need to gather information about the current network status. You'll need to know the router's current IP address, subnet mask, and, ideally, the DNS server address. This information can be found through the operating system command line or in the network connection properties.
For Windows users, the fastest way to get information is to use the command ipconfigOpen the command prompt, enter the command, and find the line "Default Gateway". This address is the current IP address of your router.
It's important to have an Ethernet cable handy to directly connect your computer to the router. While modern interfaces allow you to work over WiFi, the risk of losing the connection while applying settings is too high. A wired connection ensures a stable process.
☑️ Preparing for setup
It's also recommended to create a new address in advance. It should be in the same subnet as your ISP (unless this has changed previously) or unique to your local network. The standard range for home networks is 192.168.0.1 to 192.168.255.254.
Login to the router admin panel
To begin the process, log in to the device's web interface. Open any browser (Chrome, Firefox, or Edge) and enter the router's current IP address in the address bar. Don't use Yandex or Google search; the address is entered directly into the URL bar.
The system will ask for a login and password. By default, on most devices, such as TP-Link, Asus or D-Link uses the combination admin/admin or admin/password. If you've changed this information before, use your password. If you've lost your password, you'll have to perform a hard reset using the button. Reset on the body.
After successfully logging in, you'll find yourself on the main page of the control panel. Interfaces vary greatly from manufacturer to manufacturer, but the logic remains the same. Look for sections labeled "Network," "LAN," or "Local Network."
Some modern models with cloud service support may require login via a manufacturer account. In this case, you'll first need to find the LAN settings section, which is often hidden in the advanced settings.
Step-by-step instructions for changing your IP address
Once you've found the Local Area Network (LAN) settings section, you'll see a field commonly called "IP Address." This is the field we need to change. Enter the new address using IPv4 syntax (four numbers from 0 to 255, separated by periods).
Unless you're a network engineer and understand the specifics of other masks, make sure the Subnet Mask is set to 255.255.255.0. This is the default value for most home networks.
After entering the new address, click "Save" or "Apply." The router will warn you that the connection will be interrupted. Confirm the action.
What if the new address doesn't work?
If your router stops responding after changing the address, you may have selected an address that's outside the DHCP range or conflicts with your ISP's address. Try resetting the router using the Reset button and repeating the process, selecting an address from a different range, for example, 192.168.50.1 instead of 192.168.0.1.
Now your computer has lost connection to the router because it's still trying to communicate using the old address. You need to update the IP address on your computer or simply reconnect the cable so that the DHCP server (if enabled on the router and you changed its range) issues the new settings.
Setting up a static IP and DHCP server
When changing a router's IP address, it's critical to configure the range of addresses it distributes to clients (the DHCP pool). If the router's address is now 192.168.5.1, the distribution range should start, for example, with 192.168.5.10 and end with 192.168.5.200.
If you are planning to use static IP For certain devices (printers, CCTV cameras, game consoles), their addresses should be assigned outside the DHCP range or reserved in the router settings. This ensures that the router doesn't accidentally assign this address to another device.
The table below shows examples of correct settings for different scenarios:
| Parameter | Standard setting | Changed setting (Example) | Description |
|---|---|---|---|
| Router IP address | 192.168.0.1 | 192.168.10.1 | New gateway to enter settings |
| Subnet mask | 255.255.255.0 | 255.255.255.0 | Determines the size of the network |
| DHCP Start | 192.168.0.100 | 192.168.10.100 | The first address for clients |
| End of DHCP | 192.168.0.200 | 192.168.10.200 | Last address for clients |
Be sure to save your DHCP server settings after changing the gateway IP address. If the DHCP range remains the same (e.g., 192.168.0.x) and the router switches to 192.168.10.x, devices will not be able to connect to the internet automatically.
⚠️ Note: Interfaces and menu item names may vary depending on the firmware version and router model. Always consult the manufacturer's official documentation if you cannot find the setting you need.
Resolving connection issues after changing IP
After applying the settings, the computer may not be able to access the internet. This happens because the PC's network card has retained the old settings. You need to update the IP configuration. In Windows, this is done with the command ipconfig /renew in the command line or by simply reconnecting the network cable.
If you have lost access to the control panel, try clearing the DNS cache with the command ipconfig /flushdnsIt's also worth checking whether a static IP address has been manually configured on your computer. For proper operation on a home network, TCP/IP settings should be set to "Obtain an IP address automatically."
In rare cases, your antivirus or firewall may block the connection to a new gateway, deeming it suspicious. Check your network profile's security settings.
If nothing helps, use the button Reset Press and hold the button on the router body for 10-15 seconds while the power is on. This will restore the factory settings and the default IP address, which is located on the sticker on the bottom of the device.
Frequently Asked Questions (FAQ)
Is it possible to change the IP address remotely without being near the router?
No, this is not possible. Changing the IP address breaks the connection to the device. If you do this remotely, you will lose access to the router and will be unable to complete setup or troubleshoot errors. A direct connection is required.
Does changing the router's IP address affect internet speed?
The IP address itself (e.g., 192.168.1.1 vs. 10.0.0.1) doesn't affect data transfer speed. Speed depends on the provider's plan, cable quality, WiFi standard, and the router's processor power.
What should I do if I forgot my router's new IP address?
The only reliable way to restore access is to perform a full factory reset. After this, the router will be accessible again at the address indicated on the label on the bottom of the case.
Do I need to change the IP address for every device on my network?
No, the IP address changes only for the router (gateway). Other devices (phones, laptops) will receive new addresses automatically from the router's DHCP server or will operate in the new subnet without user intervention.
