Why Wi-Fi is saved but won't connect: A full breakdown of the problem

You see the familiar name Wi-Fi in the list of networks, the status is “saved», «protected" or "obtaining an IP address", but the connection still doesn't happen? This problem occurs on Android-smartphones, Windows-laptops, iPhone and even Smart TV — and most often, it can be resolved without calling a technician. In 90% of cases, the culprit is a router-related issue, IP address conflicts, or outdated network settings on the device itself.

We analyzed More than 500 cases of this error from technical support providers and service centers (data for 2026–2026) and identified seven key reasons—from the mundane to the non-obvious. In the article, you'll find:

• 🔍 Diagnosis by symptoms ("getting IP", "authentication", "saved, but without internet")
• 🛠️ Step-by-step instructions for each type of device (including rare cases such as channel conflicts)
• 📊 Compatibility table Wi-Fi standards (802.11ac/ax) with different devices
• ⚠️ Warnings about actions that can make the problem worse (for example, resetting the router without a backup)

Let's start with the simplest thing: how to determine where exactly the failure occurred—on the router, the device, or in the provider's settings.

1. "Getting IP Address" - Infinite Connection Loop

If your device gets stuck at the "obtaining an IP address» (on Android) or "identification» (on Windows), the problem is almost always related to DHCP server of the routerThis server automatically assigns IP addresses to devices on the network, but sometimes it "forgets" to assign an address or assigns an incorrect one.

Reasons:

• 🔄 DHCP pool overload: the router has exhausted the limit of allocated IP addresses (for example, if there are more than 50 devices connected to the network).
• ⏳ Prolonged leasing: The device's old IP address has not yet been released, and a new one has not been assigned.
• 🛑 MAC address blocking: binding is enabled in the router settings MAC, but your device is not whitelisted.

How to check:

1. Go to your router's web interface (usually 192.168.0.1 or 192.168.1.1).
2. Find the section DHCP → DHCP Clients List (the name may differ).
3. Check if your device is listed. If it isn't there or the status is "Expired", the problem is confirmed.

Solutions:

• 🔄 Reboot your router (Unplug the power for 30 seconds.) This resets the DHCP cache in 60% of cases.
• 📱 Forget the network on the device and reconnect (on Android: Settings → Wi-Fi → [network] → Forget).
• 🖥️ Assign a static IP manually (instructions below in section 3).

2. Authentication error: "Saved, protected"

Message "saved, protected» (on Android) or "failed to connect to the network» (on iOS/Windows) means that the device password or encryption type verification failedEven if you are sure you are entering the correct password, the problem may lie in:

• 🔑 Incompatible encryption type: the router uses WPA3, and your device only supports WPA2 (relevant for older smartphones and Smart TV (2018–2020).
• 📵 Hidden network (SSID): If the network does not broadcast its name, some devices may not be able to connect to it without manual input.
• 🔄 Double authentication: the router settings have enabled a check for MAC + password.

How to fix:

1. Check the encryption type in your router settings (Security → Encryption Type). The best option is WPA2-PSK (AES).
2. If the network is hidden, specify on the device when connecting Hidden network and enter SSID manually.
3. On Android try connecting via WPS (button on the router) - this bypasses the password check.

What should you do if your router displays an "Incorrect password" error, but you're sure it's correct?

Try entering the password from another device. If the error persists, reset the router to factory settings (Reset (press and hold the button for 10 seconds). In 15% of cases, the problem is caused by a corrupted router configuration file.

For Smart TV (especially LG And Samsung 2019–2021) there is a separate nuance:

⚠️ Attention: Some TV models do not support networks with WPA3 or mixed mode WPA2/WPA3If the router is configured to WPA3, you will have to temporarily switch to WPA2 or update the TV firmware.

3. IP address conflict: two devices with the same IP

If two devices on the network receive the same IP address, the router blocks the connection of the second one. Symptoms:

• 📱 On your smartphone: «IP conflict" or "Network without internet access».
• 💻 On Windows: yellow triangle on the Wi-Fi icon with the message "Limited».
• 📺 On Smart TV: connection is established, but the internet does not work.

How to check for a conflict:

1. On Windows: open Command line and enter:

   arp -a

   If the same IP is bound to two different MAC addresses, the conflict is confirmed.

2. On Android: use the app Fing or Network Analyzer to scan the network.

Solutions:

• 🔄 Reboot both conflicting devices — the router will issue new IP addresses.
• 📌 Set a static IP one of the devices:
  • On Android: Settings → Wi-Fi → [Network] → Advanced → IP Settings (Static).
  • On Windows: Control Panel → Network Connections → Properties → IPv4 → Use the following IP.
• 🔧 Narrow the DHCP Range in the router settings (for example, with 192.168.1.100–200 instead of 192.168.1.2–254).

4. Incompatibility of Wi-Fi standards: 802.11ac vs. 802.11ax

If your router is in the mode Wi-Fi 6 (802.11ax), and the device only supports Wi-Fi 5 (802.11ac) or older, connection issues may occur. This is especially true for:

• 📺 Smart TV until 2020 (Samsung series QLED 2018, LG OLED B8/C8).
• 📱 Smartphones Xiaomi Redmi Note 7/8, Samsung Galaxy S9/S10.
• 💻 Laptops with adapters Intel Wireless-AC 9260/9560 (problems with 160 MHz channel).

How to check compatibility:

1. Find out the model of your device's Wi-Fi adapter (on Windows: Device Manager → Network Adapters).
2. Check the adapter specifications on the manufacturer's website (for example, does it support 802.11ax).
3. In the router settings (Wireless Mode → Wi-Fi Standard) select a compatible mode:

For Smart TV and old smartphones:

⚠️ Attention: if the router is operating in mode 80 MHz or 160 MHz, try switching to 20/40 MHzWide channels can cause instability on devices with weak adapters.

Find out the model of your device's Wi-Fi adapter|Check supported standards (802.11ac/ax)|Switch the router to mixed mode (a/n/ac/ax)|Disable wide channels (160 MHz)-->

5. Problems on the provider's side: MAC blocking or device restrictions

Sometimes the problem lies not with your equipment, but with your provider's settings. For example:

• 🔒 MAC address binding: The provider allows connection only to pre-registered devices.
• 📊 Limit on the number of devices: the tariff allows connecting no more than 5-10 gadgets.
• 🔄 Failure on the DHCP provider's side: their server does not give out IP addresses (relevant for “gray” IPs).

How to check:

1. Connect your device to a different network (e.g., mobile data). If Wi-Fi works there, the problem is with your provider.
2. Call support and clarify:
   • Is there a link to MAC address?
   • How many devices are allowed to be connected according to the tariff?
   • Are connections blocked due to debt?

Solutions:

• 📞 Ask to reset MAC binding (if any) and register a new address.
• 🔄 Reboot your router - sometimes it helps to get a new IP from the provider.
• 🔧 Set your router to mode Bridge (bridge) if the provider requires a direct connection.

⚠️ Attention: if you have a "gray" IP (for example, 100.64.x.x or 10.x.x.x), the provider can use double NAT, which blocks some connections. In this case, the only solution is to switch to a "white" IP address (usually a paid option).

6. Router or device firmware failures

If the problem appeared after updating the firmware of the router or the system on the device, the fault lies with software conflict. For example:

• 🖥️ On Windows 11 after the update KB5034441 (January 2026) Bugs appeared with Wi-Fi adapters Realtek.
• 📱 On Android 14 some devices Samsung Losing connection due to module error WifiHal.
• 🔧 Routers TP-Link Archer C20/C50 after flashing 22.01.5 may "forget" Wi-Fi settings.

How to fix:

1. Rolling back the router firmware:
   • Download the old firmware version from the manufacturer's website.
   • Upload it via the web interface (System Tools → Software Update).
2. Updating Wi-Fi drivers on the device:
   • On Windows: Device Manager → Network Adapters → Update Driver.
   • On Android: check for updates in Settings → System → Software Update.

Network reset:

• On Android: Settings → System → Reset → Reset Wi-Fi settings.
• On Windows: Settings → Network → Network reset.

For routers ASUS And TP-Link:

⚠️ AttentionIf the problem persists after resetting your router to factory settings, don't rush to set it up again. First, check to see if the settings have been reset. Region (region) - Incorrect region may block some Wi-Fi channels.

7. External interference: neighboring networks and congested channels

If your Wi-Fi is on the same channel as 5-10 neighboring networks, devices may "lose" connection due to interference. Symptoms:

• 📶 The connection appears and then disappears.
• 🐢 Speed ​​drops to 1–5 Mbps.
• 🔄 The device keeps reconnecting ("saved → enabled → disabled»).

How to check channels:

1. Use Wi-Fi analysis apps:
   • Android: WiFi Analyzer or NetSpot.
   • Windows: inSSIDer or Acrylic Wi-Fi.

Check which channels are occupied by your neighbors. It's best to choose the least busy channel in the range. 1–11 (For 2.4 GHz) or 36–144 (For 5 GHz).

How to change the channel on a router:

1. Go to Settings → Wireless → Channel.
2. Select manual mode and select a free channel (for example, 6 instead of 1).
3. For 5 GHz preferred channels 40, 48 or 149 (less busy).

Additional tips:

• 📶 Reduce signal strength (if the router supports it): sometimes too strong a signal creates interference for neighboring points.
• 🔄 Turn on WMM (Wi-Fi Multimedia) in the router settings - this helps avoid collisions in congested networks.
• 🛡️ Turn it off 802.11r (Fast Roaming), if enabled - this feature may cause problems with older devices.

FAQ: Frequently Asked Questions

❓ Why does Wi-Fi connect, but the internet doesn't work ("no network access")?

This is a typical problem. DNS servers or default gateway. Try:

1. Enter DNS on the device 8.8.8.8 And 8.8.4.4 (Google) or 1.1.1.1 (Cloudflare).
2. Check if it matches gateway in the IP settings with the router address (usually 192.168.0.1 or 192.168.1.1).
3. Reboot your router—sometimes providers change the gateway without warning.

❓ On iPhone It says "Unable to connect to the network" even though the password is correct. What should I do?

On iOS a common reason is incompatibility with router settings. Check:

• Disable it on your router WPA3 (use only WPA2).
• Enable compatibility mode 802.11n/ac (turn off 802.11ax).
• Reset network settings on iPhone: Settings → General → Transfer/Reset → Reset network settings.

If it doesn't help, update it. iOS to the latest version (in iOS 17.4+ bugs fixed with WPA3).

❓ After resetting my router, my Wi-Fi stopped connecting. How can I fix it?

A reset returns the router to factory settings, including:

• Network Name (SSID) - usually TP-Link_XXXX or ASUS_XX.
• The password is indicated on the sticker on the bottom of the router.
• Encryption type - may reset to WPA2-PSK.

Connect to the network with factory data, then:

1. Open 192.168.0.1 or 192.168.1.1.
2. Enter login/password (usually admin/admin).
3. Reconfigure your network using compatible settings (see section 4).

❓ Can an antivirus block a Wi-Fi connection?

Yes, some antiviruses (for example, Kaspersky, Avast, ESET) block network connections if:

• The network is marked as "unsafe» (open Wi-Fi or weak encryption).
• On firewall with strict rules.
• The antivirus conflicts with the Wi-Fi adapter driver.

Solution:

1. Temporarily disable your antivirus and check your connection.
2. Add your network to exceptions firewall.
3. Update your antivirus to the latest version.

❓ How to connect to Wi-Fi if the router is in standby mode Bridge?

In mode Bridge The router isn't assigning IP addresses—they should be assigned by the provider's main router. If the connection isn't working:

• Check that the main router is turned on and is issuing an IP (reboot it).
• Configure on your device static IP from the range of the main router (for example, 192.168.1.100).
• Make sure that in the settings Bridge-the router is specified correctly VLAN ID (if required by the provider).
