Changing your wireless router's IP address is one of those procedures that may seem complicated to beginners, but is actually fundamental to properly organizing a home or office network. Users often need to change the gateway address when an IP address conflict occurs on the network or when integrating the router into an existing complex infrastructure where the standard range is occupied by other equipment. Understanding how to properly change the IP address on a Wi-Fi router gives you complete control over the topology of your local network.
Changing the address is important not only for resolving technical conflicts, but also for the basic cybersecurityStandard addresses like 192.168.0.1 or 192.168.1.1 are known to everyone, including potential attackers who might try to access your device's settings. By changing these default values, you create an additional, albeit not absolute, barrier to unauthorized access to your device's admin panel. router.
In this article, we will examine in detail the process of changing the IP address, and consider the nuances of working with DHCP server We'll explain why your computer may temporarily lose internet access after changing settings. We won't use complex terminology where simple terms can suffice, but we'll cover the key concepts needed for confident network management.
The concept of an IP address and the role of a gateway in a local network
Before changing the equipment settings, it's important to clearly understand what exactly we're changing. A router's IP address is most often referred to as a router's IP address in the context of a local network. default gateway (Default Gateway). This is a unique numerical identifier that all devices on your network (smartphones, laptops, TVs) use to find the router and access the "external" internet through it.
It's important not to confuse the external IP address assigned by your ISP with the router's internal address. The external address can be dynamic or static, and changing it often requires contacting your ISP or using special services. The internal address, which we'll be changing, works exclusively within your apartment or office and is governed by the protocol. TCP/IP.
⚠️ Warning: Changing your router's IP address will disconnect all connected devices until they receive the new network settings automatically or manually.
Standard address ranges used by manufacturers typically refer to private Class C networks. Common options include 192.168.0.1, 192.168.1.1, and 10.0.0.1. Knowing the current address is critical, as this is what you'll need to enter into your browser to access the control panel.
Preparing to change your router's network settings
Changing your IP address requires some preparation to avoid losing access to your admin panel and being unable to restore your settings. The first step should always be physically connecting your computer to the router via LAN cable (Ethernet). While modern interfaces allow you to work via Wi-Fi, a wired connection ensures you won't lose connection when the network module reboots.
The second important point is to find out your computer's current IP address. If your PC is configured to obtain an address automatically (via DHCP), it will change automatically after changing the router settings. However, if you have a static IP address, you will need to change it manually to match the router's new subnet.
☑️ Preparing to change your IP address
It is also recommended to make a backup of the current configuration. In most modern models, TP-Link, Asus or Keenetic There's a settings export function. This will allow you to quickly restore network functionality if you make an error when entering new parameters.
Instructions: How to log in to the admin panel
To get started, 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 confuse the address bar with the Yandex or Google search bar—the address should be entered exactly where you would normally enter website URLs.
After entering the address, the system will ask for your username and password. If you've never changed these details, they're likely default. For most models, this is either admin/admin or admin/password. The exact details are always listed on a sticker on the bottom of the device.
Standard credentials:Login: admin
Password: admin
(or indicated on the device label)
If the default passwords don't work, they may have been changed previously. In this case, you'll need to perform a hard reset by pressing the recessed button on the router body for 10-15 seconds while the power is on.
What to do if you forgot your router password?
If the default password doesn't work, and you've changed it and forgotten it, the only solution is a factory reset. Locate the reset hole on the router, turn it on, press the button inside with a paperclip, and hold it there for 10-15 seconds until the lights flash. After this, the router will reboot with the factory settings.
Step-by-step change of the LAN interface IP address
The settings interface looks different for different manufacturers, but the logic remains the same. You need to find the section responsible for the local network. It may be called LAN, Local Network, "Local Network," or "TCP/IP Settings." This is where the field for changing the IP address is located.
In the window that opens, find the field labeled "IP Address" or "IPv4 Address." By default, it will contain a value like 192.168.0.1. You need to change the last digit (octet) or, if necessary, the entire address, following the addressing rules. For example, you could change the address to 192.168.0.254 or 10.0.0.1.
Pay special attention to the subnet mask. In 99% of cases, it should remain the default for home networks: 255.255.255.0Changing the mask without a thorough understanding of the network architecture can result in devices no longer "seeing" each other.
After entering the new address, the system may prompt you to reboot. Agree. Remember that after saving the settings, access to the control panel using the old address will be blocked. To restore the settings, you will need to enter the new IP address in your browser.
Configuring a DHCP server after changing the address
Changing the IP address of the router itself is inextricably linked with the built-in settings DHCP serversThis service automatically assigns addresses to all connected devices. If you change the router's address to 192.168.5.1, but the DHCP range remains 192.168.0.100 - 192.168.0.200, the devices will receive addresses from one subnet, but the gateway will be in another, rendering the internet unusable.
You must ensure that the "Start Address" and "End Address" of the DHCP pool are in the same subnet as the new router IP. For example, if the new router IP is 192.168.5.1, then the DHCP pool should be, for example, from 192.168.5.10 to 192.168.5.200.
| Parameter | Old meaning (Example) | New value (Example) | Status |
|---|---|---|---|
| Router IP | 192.168.0.1 | 192.168.88.1 | Changed |
| Subnet mask | 255.255.255.0 | 255.255.255.0 | No changes |
| DHCP Start | 192.168.0.100 | 192.168.88.100 | Needs editing |
| DHCP End | 192.168.0.200 | 192.168.88.200 | Needs editing |
Also check the address lease time. For a stable home network, it's recommended to set it between 120 minutes and 1440 minutes (1 day). A lease time that's too short can put unnecessary strain on the router's processor due to constant update requests.
Possible problems and solutions
After changing settings, users often encounter internet connection failure and webpages that won't open. The most common cause is a DNS cache or old network settings on the computer. Your PC may "remember" the old gateway and try to connect to the old address.
To resolve the issue, try updating the IP configuration on your computer. In Windows, this can be done via the command line. Click Win + R, enter cmd and press Enter. In the black window, enter the command to reset and obtain a new address.
ipconfig /releaseipconfig /renew
ipconfig /flushdns
If you still can't access the internet after these steps, check that the "Default Gateway" is correctly configured in your computer's network adapter properties. It should match the new IP address you assigned to the router.
⚠️ Note: Router interfaces are constantly being updated. The location of the "LAN" or "Network" menu may vary depending on the firmware version. If you cannot find the desired menu item, please refer to the official documentation from the manufacturer of your model.
Another rare, but possible, issue is an address conflict. If you have another router or device on your network with a static IP address that matches your primary router's new address, a conflict will occur. Make sure the address you choose is unique within your local network.
Frequently Asked Questions (FAQ)
Will my external IP address for websites change after changing my router settings?
No, your internal IP address (LAN) and the external IP (WAN) that websites see are different. Changing your local address does not affect how you are seen online. To change your external IP, you need to reboot your router (if the address is dynamic) or use a proxy or VPN.
What should I do if I changed my IP and forgot the new address?
If you don't remember the new address, the only reliable way to regain access is to perform a factory reset. This will reset the router to the address indicated on the sticker on the bottom of the device.
Is it possible to use the address 192.168.0.1 for a second router in the same network?
No, two devices with the same IP address cannot be on the same local network. This will cause a conflict, and the network will stop functioning properly. The second router (if it's operating in access point mode) must be assigned a unique address, for example, 192.168.0.2.
Does changing IP address affect internet speed?
The IP address itself doesn't affect speed. However, if you incorrectly configure the subnet mask or DNS servers when changing your IP address, your speed may drop or even lose internet access altogether. If configured correctly, your speed will remain the same.
Do I need to reboot my computer after changing my router's IP address?
This is recommended, but not always necessary. The computer should re-request the settings from the DHCP server. Often, simply reconnecting to the Wi-Fi network or running the IP update command in the command line helps.
