The question of which IP address needs to be entered for Wi-Fi to function correctly often arises when manually setting up network connections. Users often need to change settings when a device doesn't automatically obtain an address or when access to a local server is required. Incorrect actions in this section can result in complete loss of internet access, so it's important to understand the difference between the gateway address and the device's address.
Most home networks use a standard protocol IPv4, which requires filling out four main fields. The primary reference point is always your router's address, which by default is usually 192.168.0.1 or 192.168.1.1. This number determines the sequence of numbers you enter into the network card settings of your computer or smartphone.
Don't be intimidated by the technical terms, as the setup process is quite logical. IP address — this is a unique number of your device on the network, and subnet mask Determines its size. Properly configuring these parameters allows your laptop or phone to "see" the router and connect to the global network through it, avoiding conflicts with other devices.
⚠️ Attention: Before making any changes to your network settings, be sure to write down the current values. If you enter incorrect information, restoring internet access without the original information will be more difficult, especially if you don't remember the password for the router's admin panel.
Understanding the IP addressing structure in a home network
To correctly answer the question of which IP address to assign, you need to understand the address hierarchy. A network is built on the client-server principle, where the router acts as the server (gateway), and your devices are the clients. The gateway address is the "door" to the internet, and it must be entered correctly, otherwise the traffic will simply not flow.
Typically, private networks reserve a specific range of addresses. The most popular are Class C networks, which start with 192.168The third digit in the sequence often denotes the subnet, and the fourth denotes a specific device. For example, if a gateway has the address 192.168.1.1, then it makes sense to assign an address to your computer 192.168.1.50 or any other in the same range, but not occupied by other gadgets.
It is important not to get confused static IP, which you manually enter on your computer, and the WAN address assigned by your ISP. For local Wi-Fi setup, we're exclusively interested in the local network (LAN). The following rule applies: the first three numbers of the device and gateway addresses must match; only the last number can differ.
There is also a concept DNS serversThese are internet directory services that translate website names into numeric codes. If you enter the IP manually, you often need to specify the DNS as well, otherwise the browser won't be able to open pages by domain name, although it will still be able to connect to the server.
How to find your current gateway IP address and network settings
Before entering any numbers into the settings, you need to know your network's current parameters. This can be done through the operating system's command line, which is the most reliable method. On Windows, simply press a key combination. Win + R, enter cmd and press Enter.
In the black window that opens, enter the command ipconfig and press Enter. The system will display a long list of options. You need the section that corresponds to your wireless connection (usually it's called "Wireless Network" or "Wireless LAN Adapter"). Find the line Main gateway (Default Gateway) is the IP that needs to be entered in the corresponding field of the device settings.
Wireless Network Adapter:
IPv4 address. . . . . . . . . . . : 192.168.1.45
Subnet mask. . . . . . . . . : 255.255.255.0
Default gateway . . . . . . . . : 192.168.1.1
By looking at the command output, you will see the complete picture. IPv4 address - this is what you have now, Subnet mask - almost always 255.255.255.0, A Gateway — router address. If you want to specify a static address, take the first three numbers from the gateway address and replace the fourth with any available number (for example, from 2 to 254).
Setting up a static IP address on Windows 10 and 11
The process of assigning an address to a computer in the Windows operating system requires careful attention. First, open the "Settings" menu from the Start menu or the keyboard shortcut Win + IGo to the "Network & Internet" section, then select "Wi-Fi" and click on the name of your connected network.
In the window that opens, find the "IP Assignment" section and click "Edit." Select "Manual" from the drop-down list. Here, you'll need to enable the IPv4 switch. These are the fields where you'll need to enter the information we determined earlier: the IP address, mask, and gateway.
☑️ Windows network setup checklist
Pay special attention to the field Preferred DNSIf your ISP doesn't provide its own name servers, you can use public and fast addresses from Google (8.8.8.8) or Cloudflare (1.1.1.1). This often helps websites load faster and improves connection stability.
After entering all the numbers, click "Save." The system will disconnect for a few seconds and then attempt to reconnect with the new settings. If the address was selected correctly and isn't in use by another device, the Wi-Fi icon will become active, and internet access will be restored.
⚠️ Attention: If the network status changes to "No Internet Access" after saving the settings, you likely entered the wrong gateway address or selected an IP address that is already in use by another device on the network. Reset the settings to automatic (DHCP) and try again.
Manual IP configuration on Android and iOS devices
Mobile devices also allow you to change network settings, which is sometimes necessary for connecting to hidden networks or corporate Wi-Fi. On Android, the process begins by opening Wi-Fi settings. Tap your network name or the gear icon next to it to expand the menu.
Find "IP Settings" (or "IPv4 Settings"). By default, it's set to "DHCP." Switch it to "Static." Input fields will open. In the "IP Address" field, enter the desired device address, and in "Gateway," enter the router address. The network prefix length fields are usually filled in automatically (the value is 24), which corresponds to a mask of 255.255.255.0.
In the ecosystem Apple iOS (iPhone, iPad) The logic is similar. Go to "Settings" → "Wi-Fi" and tap the blue "i" icon in a circle next to the network name. Scroll down to the "IP Configuration" section and select "Manual." Here you'll need to fill in the IP address, Subnet mask, and Router (this is the gateway) fields.
| Parameter | Meaning for Windows | Meaning for Android/iOS | Description |
|---|---|---|---|
| IP address | 192.168.1.X | 192.168.1.X | Unique device number |
| Mask | 255.255.255.0 | 24 (prefix) | Determines the size of the network |
| Gateway | 192.168.1.1 | 192.168.1.1 | Router address |
| DNS 1 | 8.8.8.8 | 8.8.8.8 | Primary name server |
What should I do if my mobile device says "Unable to obtain IP address"?
This is a common error when entering the IP address manually. Check that the IP address you entered doesn't match another device's address. Also, make sure the gateway address is entered correctly—if the router has an address of 192.168.0.1, and you enter 192.168.1.1 as the gateway, there will be no connection.
Common errors and address conflicts on the network
The most common problem with manual IP registration is address conflictThis happens when two devices on the same network are assigned the same number. For example, you manually assigned an address to a computer. 192.168.1.50, and the router automatically assigned the same address to your smartphone via DHCP. As a result, both devices will lose network connectivity.
To avoid this, when choosing a static address, it's best to use numbers from the "upper" or "lower" range, which are rarely assigned automatically. Routers usually start assigning addresses with .100 or .50. Therefore, it is safer to specify addresses in the range from .2 to .49 or from .200 to .254.
Another error is an invalid subnet mask. If you specify 255.255.0.0 instead of 255.255.255.0, the device will "think" that it is on a huge network and will stop sending requests to the gateway to access the Internet, trying to find the recipient locally.
Frequently Asked Questions (FAQ)
Can I register any IP address I like?
No, the address must match your router's subnet. If the gateway is 192.168.0.1, then the device's address must be 192.168.0.X. Furthermore, the address must not be occupied by another device and must not match the router's address.
What happens if I specify an incorrect DNS?
Websites by name (for example, google.com) will no longer open, although you'll still technically be connected to the network. You'll only be able to access websites by IP addresses (numbers). To fix this, set your DNS to 8.8.8.8 or revert to automatic DNS resolution.
Do I need to reboot my router after changing my computer's IP address?
Usually, disabling and re-enabling Wi-Fi on the computer itself or performing a network reset is sufficient. Restarting the router is rarely necessary, unless you've changed the DHCP server settings on the router itself.
How to return to automatic IP configuration?
In the same menus where you selected "Manual" or "Static," select the "Automatic (DHCP)" option. After this, the device will automatically request all the necessary parameters from the router.
