Changing internet providers or installing a new router often poses the challenge of quickly and correctly switching all devices. Reconnect to another Wi-Fi It's not just about selecting a new network from the list, but also ensuring that the old settings don't conflict. In today's digital world, where dozens of devices, from smart light bulbs to 4K TVs, are connected to the internet, a proper migration is critical.
Many users encounter a situation where automatically connecting to an old access point blocks access to a new network, even if the router is nearby. This occurs due to cached profiles and priorities built into operating systems. Understanding how this works SSID and security protocols will help you avoid long searches for the reasons for the lack of internet.
In this article, we'll cover all the nuances of migrating to a new network for various platforms. We'll cover how to forcefully "forget" the old signal, how to correctly enter security keys, and which hidden settings can interfere with stable operation. If you're upgrading your router to a model of the same brand, use the MAC address cloning feature to avoid your ISP having to reflash all your devices.
Preparing to Change Your Wi-Fi Network: Checking Your Equipment
Before you begin reconnecting your devices en masse, you need to ensure the signal source itself is working properly. The new router should be properly configured and provide a stable signal throughout the room. If you've just installed the equipment, check the indicators on the device: is the light on? WAN or Internet indicates that there is a connection with the provider.
It is important to decide on the parameters of the new network in advance. If you want to keep the network name (SSID) the same as the old router, devices may attempt to connect to it automatically using old passwords, resulting in authorization errors. In this case, it's best to temporarily change the name of the new access point so that devices recognize it as new.
Make sure you have your login information: network name and password. This information is often found on a sticker on the bottom of the router, unless you've changed it in the web interface. Accessing the router settings may require a cable connection. LAN or temporarily connecting to the device's open network.
⚠️ Important: If your ISP uses MAC address binding, be sure to clone the address of your old router to the new one or inform your ISP of the new MAC address. Otherwise, your internet connection will not work even with the correct Wi-Fi settings.
Reconnecting Android smartphones
In the Android operating system, the process of changing the network may differ depending on the OS version and the manufacturer's shell (MIUI, OneUI, ColorOS). The standard algorithm requires entering the settings menu. Typically, the path looks like this: Settings → Connections → Wi-Fi.
Find your new access point in the list of available networks. If your device was previously connected to a network with a similar name, or if you are changing the password for an existing network, the system may display an "Unable to connect" error. In this case, you need to delete the old profile. Click the gear icon or arrow next to the old network name and select Forget the Network or Delete.
After clearing the cache of old connections, find the new network in the list. When entering the password, pay attention to the letter case and keyboard layout. Android often offers to save the password to your Google account, which is convenient for automatic connections in the future, but requires syncing to be enabled.
- 📱 Open the quick settings panel by swiping down from the top.
- 📡 Make sure the Wi-Fi slider is active (blue or green).
- 🔑 Click on the new network and enter the password manually, without relying on autofill if it produces errors.
- 🔄 If the connection fails, turn Airplane Mode on and off to reboot the communication modules.
☑️ Android connection check
Setting up Wi-Fi on iPhone and iPad (iOS)
Apple devices are known for their strict security, which can sometimes prevent quick reconnections. If you've changed your router but left the same network name, your iPhone may persistently try to connect using the old password and ignore the new one. To resolve this issue, go to Settings → Wi-Fi.
Click on the blue icon «i» in the circle next to the name of the network you want to delete. In the menu that opens, select the option Forget this networkConfirm the action. Your device will now completely delete all saved data about this access point, including security certificates and passwords.
After that, find the new network in the list of available networks. iOS will prompt you to use your iCloud Keychain password if it's saved for another Apple device. If you've changed your router, this password will be incorrect, so enter it manually. It's also worth checking that the "Private Wi-Fi Address" feature isn't enabled, as it can sometimes block connections to corporate or strictly configured home networks.
For iOS 16 and later users, you can view saved passwords directly in the Wi-Fi menu. This allows you to quickly copy a password from another Apple device via AirDrop if you're setting up a new device. However, if you change routers, this feature may reuse the old password, requiring manual editing.
What to do if iPhone doesn't see a new network?
If the new network is hidden (not broadcasting its SSID), select "Other" in the Wi-Fi menu. Enter the exact network name, select the security type (usually WPA2/WPA3), and enter the password. Hidden networks won't appear in the general list until you successfully connect for the first time.
How to connect a Windows laptop to a new network
In Windows operating systems, wireless network management is done through the taskbar or settings menu. Click the globe or Wi-Fi icon in the lower-right corner of the screen (in the notification area). If the icon is hidden, click the up arrow to expand the full menu.
Windows 10 and 11 have a feature: they can automatically connect to known networks, prioritizing signal strength. If you move or change your router but the network name remains the same, your computer may appear stuck in the "No Internet Access" state. To fix this, right-click the Wi-Fi icon and select Network and Internet.
In the window that opens, find the section Managing Known NetworksThis displays a list of all networks the laptop has ever connected to. Find the old network, click on it, and select the button ForgetThis action will force the connection to be disconnected and clear the cache.
Now, select the new access point from the list of available networks. If the network is secured, a field for entering the security key will appear. Make sure the encryption type selected matches your router (usually WPA2-Personal). After a successful connection, Windows will ask if you want to make this computer visible to other devices. For a home network, it's best to select "Yes"; for a public network, select "No."

Connecting MacBook and macOS devices
Apple ecosystem users on Mac computers can manage connections via the menu in the top status bar or through System Preferences. In new versions of macOS (Ventura, Sonoma, Sequoia), the interface has changed significantly and is now similar to iPadOS. Click the Wi-Fi icon in the menu bar and select Open Wi-Fi settings....
In the list of known networks, find the one you want to remove. Click the three dots or the "More details" button next to the name, then select Forget this networkmacOS may ask you to confirm the action using your administrator password or Touch ID.
If you're using the older macOS interface (Monterey and earlier), the path will look like this: System Preferences → Network → Wi-Fi → AdvancedIn the window that opens, the "Wi-Fi" tab will display a list of preferred networks. Select the one you don't need and click the minus sign. - to delete, then press OK.
After clearing the list, select a new network. macOS will automatically offer to save the password in iCloud Keychain. This is convenient, but if you change the password on your router, make sure the password on your other devices (iPhone, iPad) is also updated, otherwise syncing may return an old, incorrect key.
- 🍏 Check your connection status: the Wi-Fi icon should be black and filled with a fan.
- 🔐 When prompted for a password, make sure Caps Lock is not enabled.
- 🌐 If the network is not found, check if Wi-Fi is disabled in Control Center.
- ⚙️ For advanced users: you can create a new "Port" in the network settings for testing without deleting the old one.
Resolving connection issues and IP conflicts
Even after entering the correct password, the device may not be able to access the internet. This is often caused by an IP address conflict or a DHCP server error. The router may not have assigned a new address to a device that was previously connected to a different network. In this case, manually resetting the network settings can help.
Most devices have a "Reset Network Settings" feature. This resets all network settings (Wi-Fi, Bluetooth, cellular data) to factory defaults. This is a drastic but effective method. After the reset, you'll have to re-enter passwords for all Wi-Fi networks, but it ensures that any hidden conflicts are removed.
Another problem is the incompatibility of frequency ranges. Modern routers operate in the following ranges: 2.4 GHz And 5 GHzOlder devices may not see 5 GHz networks, while newer devices may have difficulty receiving 2.4 GHz in noisy environments. Make sure you're connecting to a band supported by your device.
If all else fails, try setting a static IP. Go to your Wi-Fi network properties on your device, find the IP settings, and switch from DHCP to Static. Enter the address that matches your router's subnet (for example, if the router 192.168.1.1, the device can be given 192.168.1.50).
What should I do if my device says "Unable to obtain an IP address"?
This error means the router sees the device but can't assign it an address. Try rebooting the router (unplug it for 10 seconds). If that doesn't help, check to see if the DHCP address pool is full in the router settings (this is relevant for smart homes with 50+ devices). Disabling MAC address filtering in the router's security settings may also help.
Is it possible to leave the network name (SSID) the same as on the old router?
Yes, you can, but this often causes problems. Devices remember not only the name but also the unique hardware identifier (BSSID). If the BSSID changes (and it does when you change routers), the device may struggle to connect with the old keys for a long time. It's better to give the new network a new name, for example, by adding "_New" or "_5G" at the end.
How to reconnect a smart home (light bulbs, sockets)?
Smart home devices (Tuya, Xiaomi, Aqara) often don't have a password entry screen. They need to be put into pairing mode (usually by quickly turning the power on and off five times). Then, in the hub app, select "Add Device" and specify the new network. The old settings on the devices themselves will need to be reset.
Why is the speed on the new network lower than on the old one?
You may be connected to the 2.4 GHz band instead of 5 GHz, or your new router may be in an awkward location. Also, check if you're using an older encryption standard (WEP/TKIP) that's slowing down your speed. Select the appropriate security mode in your router settings. WPA2/WPA3-AES.
