"Wi-Fi is saved, but won't connect to my phone": all the reasons and solutions

You are trying to connect your phone to your home or office Wi-Fi network, but instead of connecting, you see the message Saved or "Connecting...", which hangs indefinitely? This problem occurs on Android (from Samsung Galaxy to Xiaomi Redmi) And iPhone (including the latest models iPhone 15), and either the smartphone itself or the router could be at fault. In 80% of cases, the error can be resolved without contacting a service center—you just need to figure out where exactly the problem occurred.

In this article we will look at all possible reasonsWhy Wi-Fi? saved in the phone's memory, but does not connect, — from the banal (for example, a MAC address limitation) to the rare (for example, a channel conflict in an apartment building). For each reason, we provide step-by-step instructions with illustrations from real router interfaces (TP-Link, ASUS, Keenetic) and phone numbers. At the end is an FAQ with answers to frequently asked questions and a table of common mistakes.

1. MAC address restriction in router settings

The most common reason why a phone sees the network, but does not connect to it - MAC address filtering On the router. Many users enable this feature to protect against "freeloading neighbors," but forget to whitelist new devices. A phone's MAC address can change after a factory reset or firmware update.

To check this:

• 🔧 Go to your router's control panel (usually at 192.168.1.1 or 192.168.0.1). The login and password are indicated on the device sticker.
• 📋 Find the section Wireless Network → MAC Filter (on ASUS it could be Wireless → MAC Filter).
• 🔍 Check if filtering is enabled. If so, check if your phone's MAC address is listed.

How to find out your phone's MAC address:

• 📱 On Android: Settings → About phone → General information → Wi-Fi MAC address.
• 🍎 On iPhone: Settings → General → About → Wi-Fi Address.

⚠️ Attention: If the router is in the "Allow only specified", and the phone's MAC address is not in the list, the connection will be impossible, even if the password is correct.

Make sure MAC filtering is disabled|

2. Incorrect password or encryption type

Even if you are sure that you are entering the correct password, the error may be hidden in encryption typeModern phones do not support outdated standards like WEP or TKIP, and some routers use them by default for compatibility with older devices.

What to do:

1. Go to the router settings section Wireless Network → Security Settings.
2. Install:
   • 🔒 Security type: WPA2-PSK (or WPA3-PSK, if the router supports it).
   • 🔐 Version: AES (Not TKIP!).
   • 📝 Password: minimum 8 characters, with numbers and letters.

Save the settings and reboot the router.

If your phone still won't connect after making these changes, try:

• 🔄 Remove the network from saved on your phone (Wi-Fi Settings → [network name] → Delete).
• 🔑 Re-enter your password (sometimes copying the password from the clipboard helps).

⚠️ Attention: Passwords with Cyrillic characters or special symbols (!@#$%) may cause errors on some router models. Try changing the password to a Latin-based one.

3. IP address conflict or DHCP failure

If the router cannot give the phone IP address, the connection will “hang” at the stage Obtaining an IPThis happens because:

• 🔄 Service failure DHCP on the router.
• 📱 Static IP on the phone that conflicts with other devices.
• 🛑 Exceeding the limit on connected devices (if the router limits their number).

How to fix:

Method 1: Restart DHCP on the router

1. Go to your router settings → Local Area Network → DHCP.
2. Disable and enable the service again DHCP server.
3. Save the settings and reboot the router.

Method 2: Setting up a static IP on your phone (if DHCP doesn't work)

On Android:

1. Go to Settings → Wi-Fi → [network name] → Change network.
2. Turn on Additional options → IP settings → Static.
3. Enter:
   • IP address: 192.168.1.100 (the last digit is any from 100 to 254).
   • Gateway: 192.168.1.1 (router address).
   • DNS 1: 8.8.8.8 (Google DNS).

On iPhone:

1. Settings → Wi-Fi → [networks] → Configure DNS → Manually.
2. Add 8.8.8.8 And 8.8.4.4.

4. Wi-Fi channel problems or network congestion

In apartment buildings, routers often operate on the same channel (for example, 6 or 11), which leads to ether overloadThe phone may "see" the network, but not connect due to interference. The problem may also be in channel width (For example, 40 MHz instead of 20 MHz).

How to check and fix:

1. Download a Wi-Fi analyzer app on your phone (for example, WiFi Analyzer For Android or NetSpot For iOS).
2. Check which channels are occupied by neighboring networks. Choose the least busy one (for example, 1, 13 or 48 for 5 GHz).
3. Go to your router settings → Wireless Network → Channel and set the selected channel manually.
4. Try changing it channel width With Auto on 20 MHz (especially relevant for older phones).

Problem	Signs	Solution
Channel congestion	The network keeps connecting and disconnecting. Low speed.	Change the channel manually to a free one.
Channel width 40 MHz	The phone does not connect, although other devices work.	Install 20 MHz or Auto.
Conflict with neighboring networks	Wi-Fi works at night, but disappears during the day.	Use 5 GHz (if supported).

5. Failures in the router or phone firmware

If all the settings are correct, but the problem persists, it is the fault software:

• 📴 On the router: outdated or faulty firmware.
• 📱 On the phone: a bug in the Wi-Fi module after the update Android/iOS.

Router solutions:

• 🔄 Reset your router to factory settings (button Reset for 10 seconds).
• 📥 Update the firmware via the control panel (section System → Software Update).
• 🛠️ If the router is old (for example, TP-Link TL-WR740N), try the firmware from DD-WRT or OpenWRT.

Phone solutions:

• 🔄 Restart your phone (sometimes this helps even with hardware failures).
• 📥 Update Android/iOS to the latest version.
• 🧹 Reset network settings: Settings → System → Reset → Reset Wi-Fi settings.
• 🔧 If nothing helps, reset your phone to factory settings (make a backup first!).

⚠️ Attention: On some phones (Xiaomi, Realme) After resetting the Wi-Fi settings, you may need to reactivate the module in Settings → Advanced → Tethering and portable hotspot.

What should I do if my Wi-Fi connection disappears completely after updating my router's firmware?

If after updating your router, it no longer distributes Wi-Fi (the indicator light is off), try:

1. Roll back the firmware to the previous version (if there is a backup copy).

2. Reset settings with the button Reset and configure the router again.

3. If the router isn't responding, it's possible the firmware has bricked the device. In this case, the only solution is to reflash the firmware. TFTP (look for instructions for a specific model on forums, for example, 4PDA or OpenWRT).

6. Hardware problems: Wi-Fi module or router antenna

If software methods do not help, the reason may be in iron:

• 📡 The router antenna is damaged (for example, after a fall or a blow).
• 📱 The Wi-Fi module in the phone is faulty (often after exposure to moisture).
• 🔌 Unstable router power supply (the power supply does not provide enough voltage).

How to diagnose:

1. Try connecting your phone to a different Wi-Fi network (for example, at a cafe or at a friend's house). If the problem persists, the phone is to blame.
2. Connect another device (laptop, tablet) to your router. If it still doesn't connect, the problem is with the router.
3. Check the indicators on the router: if Wi-Fi blinks abnormally (or does not light at all) - the module may have burned out.

Solutions:

• 🔧 For the router: replace the power supply (costs 300–800 ₽) or take it to a service center for antenna diagnostics.
• 📱 For a phone: If the Wi-Fi module burns out, repairs will cost 1,500–5,000 ₽ (depending on the model). iPhone Replacing a module can cost up to 10,000 ₽.

7. Features of phones of specific brands

Some manufacturers add to their devices unique features, which may interfere with the connection. Let's look at the most common cases:

Samsung Galaxy (One UI)

• 🔄 Function Smart Wi-Fi may automatically disconnect the connection if the speed is low. Disable it in Settings → Connections → Wi-Fi → Advanced → Smart Wi-Fi.
• 📡 In some models (Galaxy S22, A53) a bug with connecting to networks on the channel 13Try changing the channel on your router.

Xiaomi/Redmi/POCO (MIUI)

• 🔒 In MIUI there is a function Hidden Settings, which can block connections to "unsafe" networks. Disable it in Settings → Wi-Fi → Advanced → Secure Connection.
• 📵 If your phone previously connected to the network, but now it doesn’t want to, delete the network and add it again, after disconnecting it Auto-connection.

iPhone (iOS)

• 🔄 Function "Auto-connect" may ignore networks with a weak signal. Disable it in Settings → Wi-Fi → [networks] → Auto-connect.
• 📡 On iPhone 12/13/14 Sometimes resetting network settings helps: Settings → General → Transfer or reset iPhone → Reset network settings.

Telefonika and other budget brands

On cheap phones (for example, Doogee, Ulefone) often have weak Wi-Fi modules that do not support modern standards (WPA3, 802.11ac). The solution is to change the router settings to WPA2-PSK (AES) and the channel 20 MHz.

FAQ: Frequently Asked Questions

Why does my phone say "Saved, WPA/WPA2 protected" but won't connect?

This means that the phone recognizes the network encryption type but is unable to complete the connection. Reasons:

• Incorrect password (even if you haven't changed it, try entering it again).
• It's enabled on the router. WPA3, but the phone does not support it (switch to WPA2).
• IP address conflict (try assigning a static IP).

The Wi-Fi connects, but there's no internet access. What should I do?

If there is an exclamation mark (!), the problem is not with the connection, but with the router or provider settings:

1. Check if your internet connection is paid for by your provider.
2. Reboot your router (unplug it from the power outlet for 30 seconds).
3. Call your provider - there may be a problem on their end.
4. If you use PPPoE, check the login/password in the router settings.

My Android Wi-Fi stopped working after an update. How do I fix it?

Updates Android Sometimes Wi-Fi drivers crash. Try this:

• Reset network settings (Settings → System → Reset → Reset Wi-Fi).
• Roll back the update (if the phone supports it) Downgrade).
• Install custom firmware (for example, LineageOS).

If nothing helps, take it to a service center (the module may have burned out).

Is it possible to connect to Wi-Fi without a password if the network is saved?

No. Inscription Saved This only means that the phone has remembered the network name and (possibly) the password. If the router requires authentication, connecting without a password is impossible. Exceptions:

• The network is open (no password).
• You have previously connected to this network and the password is saved (but now the router does not accept it).

Why won't my iPhone connect to 5 GHz Wi-Fi?

Some models iPhone (especially the old ones, like iPhone 6/6S) do not support the range 5 GHzThe problem may also be in the router settings:

• The router is in the enabled mode. 802.11ac, but the phone does not support it (switch to 802.11n).
• The channel width is set to 80 MHz - try it 40 MHz or 20 MHz.
• In some countries (for example, in Russia) channels 5 GHz higher 140 may be blocked.
