"Login to Network" When Connecting to Wi-Fi: Why It Happens and How to Fix It

Message Login to the network (or Obtaining an IP address on Android) when trying to connect to Wi-Fi — one of the most common problems faced by users of smartphones, laptops, Smart TV And even smart speakers. The device seems to "freeze" at this stage, not fully connecting, and after a few seconds (or minutes) it displays an error. Is the problem the router, the device, or the provider's settings?

In practice, there are reasons for this behavior more than a dozen, and they range from the banal (for example, Incorrect password entered) to technically complex (for example, IP address conflict in a local network). In this article, we will discuss all possible scenarios, from the simplest solutions to diagnosing network protocols. You'll also learn why the problem occurs more often on Android-devices and how it relates to settings DHCP on the router.

If you are in a hurry, take advantage of it. FAQ at the end of the article, where we've collected answers to the most frequently asked questions. For a more in-depth analysis, read on: we've structured the material so even a novice can fix the problem themselves without calling a technician.

1. Incorrect password or network security type

Let's start with the most obvious: error entering password — the leading cause of freezing at the "Logging on to the network" stage. Even if you're sure you entered the combination correctly, it's worth double-checking:

• 🔑 Character case: Passwords are case sensitive. For example, WiFi_123 And wifi_123 - different passwords.
• 📱 Keyboard auto-replacement: On smartphones, the keyboard can automatically correct characters (for example, replace l on 1).
• 🔄 Hidden symbols: If your password is displayed as dots, try making it visible (click the "eye" icon in the input field).

If the password is entered correctly but the problem persists, check network security type in the router settings. Modern devices may not support outdated protocols like WEP or TKIPThe best option is WPA2-PSK (AES) or WPA3How to check:

1. Open the router's web interface (usually at 192.168.0.1 or 192.168.1.1).
2. Go to the section Wi-Fi → Security Settings (or Wireless → Security).
3. Make sure it is selected WPA2-Personal (or WPA3 for new devices).

⚠️ Attention: If your router only supports WEP, it urgently needs to be replaced - this protocol is insecure and is blocked by many modern gadgets.

2. DHCP Issues: Why Your Device Isn't Received an IP Address

Message Login to the network often means that the device is trying to get IP address from the router, but the process is delayed or fails. This is due to protocol failures. DHCP (Dynamic Host Configuration Protocol), which automatically assigns addresses to devices on a network.

Causes of problems with DHCP:

• 🔌 DHCP server is disabled on the router (static IP assigned manually).
• 📡 The IP address pool has run out. (too many devices connected).
• ⏳ Long server response (for example, due to router overload).
• 🔄 IP conflict (two devices are trying to use the same address).

How to check and fix:

1. Go to your router settings (192.168.0.1 or 192.168.1.1).
2. Find the section DHCP (or LAN → DHCP Server).
3. Make sure the server is up (Enable DHCP Server), and the range of addresses is sufficient (for example, 192.168.0.100–192.168.0.200).
4. If there are a lot of devices, increase the pool or reduce the rental time (Lease Time) up to 12–24 hours.

For Android-devices can be manually assigned a static IP:

1. Go to Settings → Wi-Fi, click on your network.
2. Select Change Network → Advanced → IP Settings.
3. Install Static and enter the IP from the router range (for example, 192.168.0.150), mask 255.255.255.0, gateway 192.168.0.1 and DNS 8.8.8.8.

3. Incompatibility of Wi-Fi standards (802.11b/g/n/ac/ax)

If your router is in the mode 802.11ac (or new 802.11ax/Wi-Fi 6), and the device only supports 802.11n, connection issues may occur. This is especially true for older smartphones, Smart TV or smart lamps.

How to check compatibility:

1. Find out which standards your device supports (check the manual or the manufacturer's website).
2. Go to the router settings section Wi-Fi → Wireless Settings.
3. View the current mode (eg. 11b/g/n mixed or 11ac only).

Solutions:

• 🔄 Change the mode to universal: install 11b/g/n mixed (for maximum compatibility) or 11n/ac mixed (to balance speed and compatibility).
• 📶 Disable wide band (40/80 MHz): Some devices do not support wide channels. Try installing 20 MHz in the channel settings.
• 🔌 Check your Wi-Fi channel: if used DF or radar channels (52-144 in the 5 GHz range), some devices may not see them.

⚠️ Attention: Changing the Wi-Fi mode on your router may temporarily disconnect all connected devices. Save the settings and reboot the router.

4. Router malfunctions: overheating, firmware, hardware failures

If the problem occurs on all devices At the same time, the router is most likely to blame. Common causes:

• 🔥 Overheat: the router is hot to the touch, often turns off or slows down.
• 🖥️ Outdated firmware: Firmware bugs may block IP allocation.
• ⚡ Unstable power supply: voltage surges or weak power supply.
• 📡 Interference from other networks: if there are many Wi-Fi stations with the same channel in the area.

Diagnostics and solutions:

1. Reboot your routerUnplug it for 30 seconds, then plug it back in. This solves the problem in 60% of cases.
2. Check the temperature: If the case is hot, provide ventilation (do not place in a closed cabinet).
3. Update the firmware:
   1. Download the latest version from the manufacturer's website (for example, for TP-Link — tp-link.com).
   2. Go to the router's web interface (192.168.0.1) and update the software in the section System Tools → Firmware Upgrade.
4. Reset settings: press the button Reset on the back panel of the router (hold for 10 seconds). After resetting, all settings (including the Wi-Fi password) will return to factory settings!

If the router continues to malfunction, try connecting it to a different power source or test it with a different power supply (if you have a spare one).

How to check for interference from other networks?

Install an app like this on your smartphone Wi-Fi Analyzer (Android) or NetSpot (iOS). It will show channel load. If your channel (for example, 6) is overloaded, change it in your router settings to a less crowded one (for example, 1 or 11).

5. Device-side problems: drivers, network settings, viruses

If "Login to the network" only appears on one device (for example, a smartphone or laptop), the problem lies within it. Scenarios to consider:

For Windows:

• 🖥️ Outdated Wi-Fi drivers: go to Device Manager → Network Adapters, update the driver for your adapter (for example, Intel Wireless-AC 9560).
• 🔧 Reset the TCP/IP stack: open Command line as administrator and run:

  netsh int ip reset
  netsh winsock reset

  Then restart your PC.

• 🛡️ Disable your antivirus/firewall: Sometimes they block network connections. Try disabling them temporarily. Windows Defender or a third-party antivirus.

For Android/iOS:

• 📱 Reset network settings:
  • On Android: Settings → System → Reset → Reset Wi-Fi, mobile network, and Bluetooth settings.
  • On iPhone: Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings.
• 🔄 Forget the network: Delete the saved Wi-Fi network and reconnect.
• 📦 Clear the cache of system applications (For Android): Settings → Apps → Three dots → System apps → Wi-Fi → Clear cache.

For Smart TV and set-top boxes:

• 📺 Update the firmware: on LG webOS, Samsung Tizen or Android TV check for updates in the section Support → Software Update.
• 🔌 Reset network settings to factory settings.
• 🔄 Try connecting via cable (if there is a port Ethernet) to exclude the problem with the Wi-Fi module.

6. Problems with the Internet provider: blocking, restrictions, failures

Less often, but accurately: the problem may lie on your side Internet providerPossible reasons:

• 🚫 MAC address blocking: Some providers bind access to a specific device (for example, a router). If you've changed your router, it MAC address may not be registered.
• 📉 Limit on the number of devices: The tariff may have a limit on the number of connected gadgets (for example, no more than 5 at a time).
• 🔌 Technical work: the provider may have temporarily disconnected DHCP or change connection settings.
• 📡 Changing the connection type: for example, the transition from PPPoE on Dynamic IP without your knowledge.

How to check:

1. Connect your computer directly to the provider's cable (without a router). If the internet works, the problem is with the router.
2. Call your provider's support team and clarify:
   • Is there a link to MAC address (if yes, ask to add a new one).
   • Have your connection settings changed (for example, VLAN ID or authentication type).
   • Is there a limit on the number of devices in your plan?

Check it out router logs for errors: in the web interface, find the section System Log or Journal.

⚠️ Attention: Internet connection settings (e.g. PPPoE, VLAN) may be changed by the provider without notice. If your internet connection is lost after updating your router firmware, check these settings!

7. IP address conflict or incorrect DNS settings

If two devices on the network receive the same IP address, a conflict arises and one of them (or both) cannot connect. Problems can also be caused by Incorrect DNS settings.

How to check for IP conflict:

1. On Windows open Command line and enter:

   ipconfig /all

   Look at the line IPv4 addressIf it starts with 169.254.x.x, Means, DHCP didn't work.

2. On Android install the application Network Info II and check the current IP.
3. If you see duplicate IP addresses on two devices, reboot your router—it should assign new addresses.

How to fix DNS problems:

• 🔧 Set DNS manually:
  • On Windows: Control Panel → Network Connections → Wi-Fi Properties → Internet Protocol Version 4 → Use the following DNS addresses. Specify 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
  • On Android: In the Wi-Fi settings, select Edit Network → Advanced → DNS Settings.
• 🔄 Flush your DNS cache:
  • On Windows: do it in Command line:

    ipconfig /flushdns

  • On macOS:

    sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

8. Hardware faults: antennas, Wi-Fi modules, cables

If all software methods have been tried but the problem persists, it is possible hardware malfunctions:

• 📡 The router antenna is damaged: physical defects (cracks, breaks) or oxidation of contacts.
• 🖥️ The device's Wi-Fi module is faulty: for example, after a smartphone falls or a laptop overheats.
• 🔌 Problems with the provider's cable: break, poor contact in the connector or damage to the braid.
• ⚡ Unstable power supply: Power surges could damage the router's power supply.

How to diagnose:

1. Check the router on another device: If no device connects, the problem is in the router.
2. Connect to another Wi-Fi (for example, from a phone as an access point): if the device connects, its module is working properly.
3. Inspect the cables:
   • Disconnect the provider cable from the router and check for damage.
   • Try connecting the cable directly to the PC (if you have a network card).
4. Check your router's indicators:
   • 🟢 Green/blue light — normal.
   • 🟠 Yellow/flashing red — Internet connection error.
   • ❌ There is no light - no power or the module is burned out.

If you suspect a router malfunction, but it's under warranty, contact a service center. Self-repair (such as soldering an antenna) may void your warranty.

FAQ: Frequently asked questions about the "Logging on to the network" problem

❓ Why does it say "Obtaining IP address" on Android, but connects fine on iPhone?

This is due to different operating algorithms. DHCP-clients. Android it takes longer to receive a response from the router, and iOS Switches to backup settings faster. Solutions:

• On Android Set a static IP (see section 2).
• Reduce the IP lease time in your router settings (for example, from 24 hours to 12).
• Update your router's firmware—new versions often fix bugs. DHCP.

❓ After resetting my router, my Wi-Fi works, but I can't connect to the internet. What should I do?

Most likely, your connection to your ISP isn't configured. You need to:

1. Log in to the router's web interface (192.168.0.1 or 192.168.1.1).
2. Find a section WAN or Internet.
3. Select connection type (PPPoE, Dynamic IP etc.) and enter the data from the provider (login/password, VLAN ID if needed).
4. Save settings and reboot the router.

If you don’t know your connection type, call your provider’s support team.

❓ My Smart TV says "Logging on to the network," but everything works on my phone. What's wrong?

The reasons may be as follows:

• Outdated TV firmware: update the software in the section Support → Software Update.
• Incompatibility of Wi-Fi standards: enabled on the router 802.11ac, and the TV only supports 802.11n. Change the mode to 11b/g/n mixed.
• MAC address blocking: some televisions (eg. Samsung) have non-standard MAC addresses, which your router may be blocking. Try disabling filtering. MAC in the router settings.
• Wi-Fi TV module failure: try connecting via cable (Ethernet) or reset the TV's network settings.

❓ Can an antivirus block a Wi-Fi connection?

Yes, some antiviruses (for example, Kaspersky, Avast, ESET) have built-in firewalls that can block DHCP requests or restrict network access. To check:

1. Temporarily disable your antivirus and try connecting again.
2. If this helps, add your network to your antivirus firewall exceptions.
3. Check your settings Firewall In your antivirus: sometimes there is an option called "Block new connections".

On Windows It's also worth checking the built-in Windows Defender: open Windows Security → Firewall and Network Protection and temporarily disable it.

❓ How can I tell if the router or the device is at fault?

Simple test:

1. Try connecting to Wi-Fi another device (for example, a smartphone instead of a laptop).
2. If the second device connects normally, the problem is with the first device (drivers, settings, hardware failure).
3. If none of your devices connect, the problem is with your router or your provider's settings.

Also try connecting to another Wi-Fi network (For example, using a phone as an access point). If the connection is successful, your router or its settings are faulty.
