Many users are familiar with the situation where, when trying to connect to a wireless network, instead of the usual internet connection, you see the notification "Login required." This is standard behavior. Captive Portal — a mechanism that redirects your browser to an authorization page before granting access to the global network. This is most often found in public places such as cafes, airports, hotels, or hotel rooms, where you are required to accept terms of use or enter a code.
However, the problem takes on a different dimension if such a window pops up on a home router or on a trusted network where no passwords are required. In this case, the device may block access to websites, claiming that login is still required, even though you're already authorized. This behavior is often associated with DNS conflicts, outdated cached data, or incorrect operation of the operating system's network services.
Ignoring this error can result in your device attempting to connect to a non-existent authentication server, constantly interrupting real traffic. To restore stable access, you should check your DNS settings, clear your network cache, and ensure that your router doesn't require a firmware update or security protocol change. Below, we'll cover specific steps for different devices.
⚠️ Attention: If the login window appears on your home network, this may indicate DNS hijacking. Make sure your router settings don't include any third-party addresses you didn't configure.
Why does the system require WiFi authorization?
The forced authorization mechanism is created by the ISP or network administrator to control user access. When you connect, the router intercepts your first HTTP request and redirects it to a special portal. If this process gets stuck, the operating system continues to think you're in the captive zone and blocks further connections. This is often caused by time desynchronization or incorrect date settings on the device.
In addition, modern operating systems such as Android And iOS, have built-in internet availability checks. They send requests to specific servers (for example, connectivitycheck.gstatic.com or c.apple.com). If the server's response differs from the expected value or arrives with a delay, the system blocks the network, deeming it unsafe or requiring additional login. This is a protective mechanism that sometimes operates too aggressively.
Another common cause is using a static IP address or manually setting DNS servers that are currently unresponsive. If your phone or laptop is trying to reach the authentication server at an address that the network blocks or doesn't route, the login loop will never break. In such cases, resetting the network settings to factory defaults can help.
How to remove WiFi login on Android
On devices running Android The problem can be solved through the network settings menu. First, try simply "Forgetting" the network. Go to Settings → Connections → Wi-Fi, tap your network name and select "Delete" or "Forget." Then reconnect by entering the password. This action clears the local authorization cache for the specific access point.
If reconnecting doesn't help, you need to change your DNS settings. In the Wi-Fi menu, click the gear icon or long-tap on the network name, select "Edit" or "Advanced." Find "IP Settings" and switch from "Static" to DHCPIf DHCP is already installed, try manually entering reliable DNS servers, such as those from Google: 8.8.8.8 And 8.8.4.4This often bypasses portal blocking.
In more complex cases, resetting network settings can help. Please note that this action will delete all saved Wi-Fi passwords and Bluetooth pairings on the device. The path to this function typically looks like this: Settings → System → Reset settings → Reset network settingsAfter rebooting, the phone will search for the network as if it were the first time, which should resolve the frozen authorization status.

Troubleshooting for iPhone and iPad (iOS)
Ecosystem users Apple I also often encounter the endless "Login Required" window. On iOS, the first step should be to disable the "Private Wi-Fi Address" feature for the problematic network. Go to Settings → Wi-Fi, click the blue information icon (i) next to the network, and turn off the "Private Address" switch. This will force the device to use its real MAC address, which is sometimes required for corporate or public portals to function properly.
The second effective method is disabling automatic connection. In the same network information menu, turn off the "Auto-connect" toggle. Then completely turn off Wi-Fi in the control center (not just the network, but the module itself) and turn it back on. Then, tap the network manually. If the system asks if you want to join a network that doesn't provide internet access, agree.
In some cases, switching the date helps. Set it in the settings. General → Date and Time any other date (for example, tomorrow), wait a few seconds, and then return to automatic detection. This updates the SSL certificates and may unblock the frozen connection verification process. If all else fails, reset your network settings via General → Transfer or reset iPhone → Reset → Reset network settings.
Why won't Safari open the login page?
The built-in Safari browser often blocks redirect pop-ups for security reasons. Try opening the Wi-Fi settings, tapping the network icon, and selecting "Configure DNS Server," then canceling the action—this sometimes forces a connection refresh.
Windows Setup: Clear DNS and Reset TCP/IP
In the operating system Windows 10/11 The "Login Required" notification often appears in the system tray, blocking browsers. The quickest solution is to use the command line. Click Win + X and select "Terminal (Administrator)" or "Command Prompt (Administrator)". You will need to run the command to reset the TCP/IP stack and flush DNS.
ipconfig /flushdnsipconfig /release
ipconfig /renew
netsh winsock reset
After running these commands, be sure to restart your computer. If the problem persists, check your proxy settings. Go to Settings → Network & Internet → Proxy ServerMake sure "Use proxy server" is disabled in the manual settings section. Sometimes malware or malfunctioning programs change these settings, redirecting traffic to the local portal.
You should also check the Network Connection Manager service. Click Win + R, enter services.msc and find it in the list Network List ServiceMake sure it's running and the startup type is set to "Automatic." If the service is stopped, Windows won't be able to correctly determine your internet connection status and will constantly require you to sign in.
Router diagnostics and Captive Portal setup
If you are the network administrator and the login window appears for all users, it is possible that the Hot Spot or Guest Portal feature is enabled on the router and configured incorrectly. Log in to the router's web interface (usually at 192.168.0.1 or 192.168.1.1). Find the section related to guest networking or authorization.
Check that the "Require Authorization" option is not enabled for all devices. If you don't plan to use the welcome page, you should disable this feature. It's also a good idea to check your router's time settings. If the clock is out of sync, security certificates may be invalidated, causing constant login requests.
The table below shows the standard addresses for entering the settings of popular router models, where you can check these parameters:
| Router brand | Entrance address | Settings section |
|---|---|---|
| TP-Link | 192.168.0.1 |
Wireless → Wireless Authentication |
| Asus | 192.168.1.1 |
Guest Network → Enable Guest Network |
| Keenetic | 192.168.1.1 |
My Networks and Wi-Fi → Access Points |
| MikroTik | 192.168.88.1 |
IP → Hotspot |
⚠️ Attention: Router interfaces are constantly being updated. Menu item names may differ depending on the firmware version. If you're unsure of what you're doing, it's best to reset the router to factory settings (press the Reset button), but keep in mind that this will erase all your provider settings.
Frequently Asked Questions (FAQ)
Why does the "Login Required" window not disappear even after entering the password?
Most likely, your browser is blocking the redirect or is using a secure connection (HTTPS), which prevents the router from replacing the page. Try visiting an unencrypted website, for example. http://neverssl.comto force the portal to appear.
Is it safe to enter the card password on such a network?
No, this is extremely risky. Login pages on public networks often lack adequate security. Enter only the necessary authorization information (phone number, code from SMS), but never enter bank card details or passwords for important services until you're fully connected.
Can a virus cause a constant login request?
Yes, some types of malware can change DNS or proxy settings, redirecting you to phishing pages that mimic a WiFi login. Be sure to scan your device with an antivirus if the problem only occurs on your home network.
What to do if there is no reset button on the router?
Most routers have a reset button integrated with the power button or located inside a hole. Press it with a paperclip and hold for 10-15 seconds until the LEDs blink. If there's no physical button, you can reset the router via the web interface if you have cable access.
Will installing a third-party WiFi app help?
Apps like "WiFi Analyzer" can show signal strength and channels, but they can't fix system authentication errors at the OS level. To resolve the "Login required" issue, it's best to use the system's built-in diagnostic tools.
