Many people are familiar with the situation when a device suddenly refuses to connect to a wireless network, and the screen prompts you to "connect to the Wi-Fi network, make sure it's working, and then start the setup again." This is a standard system protection algorithm that is triggered when critical discrepancies in security settings are detected or when an IP address cannot be obtained from the router. Instead of panicking, it's worth understanding that the system simply requires a "clean slate" to establish a connection.
Often, the problem lies not in a hardware failure, but in a software conflict: the smartphone “remembers” old encryption keys that the router has already changed, or the DHCP server is frozen and does not issue a new address. Forced disconnection A complete reset of the device's network configuration resolves the issue in 90% of cases within a couple of minutes. We'll explain how to properly perform this procedure on different platforms.
It is important to understand that the error message may vary depending on the operating system version and the manufacturer of the gadget. Android This often appears as "Unable to obtain IP address" and on iPhone — "Unable to connect to the network." The key point is to forcefully delete the network profile from the device's memory, and not simply turn off the Wi-Fi slider. This is the only way to force the gadget to request the latest data again.
Why does the system require a restart?
When you see a request to restart the setup, it means the handshake protocol between the client and the access point has been interrupted. The router and your device exchange data packets containing information about encryption (WPA2/WPA3), frequency channel, and MAC address. If even one parameter doesn't match the cached entries, the connection is blocked for security purposes. security.
A common cause of failure is a DHCP table overflow. The router has a limit on the number of devices that can connect. If a guest connected and then disconnected, its address could be "stuck" in memory, and the new device (or yours, which changed its MAC address for privacy) simply doesn't have enough free IP. In this case, the system can't complete the connection chain.
It's also worth considering the human factor: the password may have been changed by the network administrator, but your device continues to attempt to log in using the old credentials. A constant authorization attempt is running in the background, blocking the ability to enter a new password. This is why Windows or Android They advise forgetting the network to erase the erroneous data.
⚠️ Note: If the error appears on all devices simultaneously, the problem is most likely not with the devices, but with the router itself or the ISP. Check the indicators on the router.
Actions on Android and iPhone smartphones
On mobile platforms, the "forget network" procedure is a key diagnostic tool. This action deletes the saved profile, including passwords, static IP addresses, and proxy settings, if they were set manually. The device then perceives the network as new and unknown.
For users Android The path usually lies through the settings menu. You need to go to the wireless networks section, find the desired SSID (network name), and select the delete option. On different shells (Samsung One UI, Xiaomi MIUI, Stock Android) The names may differ, but the essence remains the same. It's important not just to turn off Wi-Fi, but to actually delete the profile.

If resetting the profile doesn't help, you should try resetting the network settings completely, but this will delete all saved passwords.
☑️ Checking phone settings
Instructions for Windows 10 and 11
In operating systems Microsoft Wireless network profiles are managed through the settings menu or command line. It often happens that the network adapter driver is working correctly, but the profile saved in the system contains a configuration error. Reset network settings In Windows - a radical but effective method.
First, try the standard interface method. Open the list of available networks, right-click the problematic access point, and select "Forget." If that doesn't help, you can use more advanced tools via the command line, but this requires caution.
Follow these steps to completely reset the TCP/IP stack and profiles:
netsh winsock resetnetsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
After running these commands in the terminal with administrator rights, it is necessary reboot computer. This will clear the DNS cache and reset any network sockets that may be stuck. If that doesn't help, under "Network & Internet" -> "Advanced network settings," there's a "Network reset" button that will reinstall your network adapters.
What to do if the drivers are not installed?
If Windows cannot find the drivers after resetting the network, you will need another internet source (such as a USB modem or phone) to automatically download, or a pre-downloaded network card driver installer.
Rebooting and resetting the router
The phrase "make sure the network is working" in an error message is often ignored by users, and in vain. A router is a mini-computer that can also overheat or suffer from software glitches. Simply power cycling the device (in a 10-15 second cycle) can clear temporary errors from the device's RAM.
If a simple reboot doesn't work, your router's security settings or communication channels may be corrupted. In this case, you may need to log in to the administrator's web interface. It's usually accessible at 192.168.0.1 or 192.168.1.1Here, it's worth checking whether MAC address filtering is enabled, which could be blocking your device.
| Action | How to perform | Result |
|---|---|---|
| Soft Reset | Unplug from power outlet for 15 seconds | Clearing the temporary cache |
| Hard Reset | Press and hold the Reset button for 10-20 seconds | Full factory reset |
| Software update | Via the router's web interface | Fixing firmware bugs |
| Changing the channel | In Wireless Settings | Eliminating interference from neighbors |
The last resort is to perform a full factory reset (hard reset). To do this, find the small hole marked Reset on the body and press it with a paper clip. Attention: After this, you will have to set up your Internet connection again, as all user data, including your ISP login and password, will be deleted.
Working with static IP and DNS
One of the hidden causes of the "start setup again" error is an IP address conflict. If your device has a manually assigned static IP address that is already taken by another device on the network, the router will reject the connection. Obtaining an address automatically (DHCP) resolves most such issues.
Check your IP settings in your network properties. In Windows, this is done via Control Panel -> Network connections -> Properties -> Internet Protocol version 4 (TCP/IPv4)Make sure the "Obtain an IP address automatically" and "Obtain DNS server address automatically" boxes are checked.
Sometimes providers block default DNS, which leads to false connection errors. Try setting up public DNS from Google or Cloudflare if the automatic ones aren't working. This often helps when the network is formally connected, but the internet isn't transmitting, and the system requires reconfiguration.
- 🌐 Google DNS:
8.8.8.8And8.8.4.4 - 🛡️ Cloudflare DNS:
1.1.1.1And1.0.0.1 - ⚙️ Yandex DNS:
77.88.8.8And77.88.8.1
⚠️ Note: The IP address settings interface may vary depending on your OS version and router model. If you're unsure about what you're doing, it's best to leave the settings on "Automatic."
Specifics of connecting game consoles and TVs
Smart TVs (Smart TV) and game consoles (PlayStation, Xbox) have their own Wi-Fi performance quirks. Their network modules are often less sensitive than those in smartphones and are less able to cope with frequent connection drops or complex passwords. Connection errors on TVs can often be resolved by simply changing the region in the router settings.
For example, if the router is set to "USA" or "Japan" mode, some European TVs may not see the network or refuse to connect due to restrictions on certain channels (channels 12 and 13). Setting the router's wireless mode to "Russia" or "Europe" often resolves the issue.
It's also worth checking the date and time on consoles and TVs. If the system date is incorrect, security certificates (SSL) will fail verification, and the device will return a connection error, requiring a restart. Synchronizing the time online or manually is a must.
Why isn't 5GHz always better?
Older TVs and budget set-top boxes may not work reliably in the 5 GHz band. If the signal is weak, try switching your router to 2.4 GHz mode for greater range and compatibility.
Frequently Asked Questions (FAQ)
Why does my phone say "Saved" but the internet doesn't work?
The "Saved" status means the device successfully authenticated with the password but was unable to access the global network. Check if the internet is available on other devices. If not, the issue is with your ISP. If it is, try changing the DNS on your phone or forgetting the network and reconnecting.
Can antivirus software block Wi-Fi connections?
Yes, some firewall features in third-party antivirus programs can block connections to new or public networks. Try temporarily disabling network protection in your antivirus and testing your connection.
What should I do if I forgot my Wi-Fi password after a reset?
If you reset your router to factory settings, the password will be the same as the one on the sticker on the bottom of the device. If you changed the password in the interface and forgot it, you'll need to reset the router using the Reset button to regain access to the settings.
How often should I reboot my router?
For stable operation, it's recommended to reboot your router at least once a week. This helps clear memory errors and refresh the connection with your ISP, preventing many connection issues.
