Wi-Fi won't connect to my phone even though the password is correct: what should I do?

The situation is familiar to many: you enter the Wi-Fi password on your phone, but instead of connecting, you see the message "Connecting...", "Saved, WPA/WPA2 protection" or "Authentication...", and then an error. However, the password is definitely correct (you just checked it on your laptop or tablet), and the internet works on other devices. What's wrong, and how can I finally get my phone to connect to the network?

The problem may lie in the settings router, and in phone software failuresSometimes even the guilty one security protocol or broadcast channel Wi-Fi. In this article, we'll cover all possible reasons and we will give step-by-step instructions For Android And iOS, including rare cases that are not covered in standard manuals.

1. Restart your router and phone – the easiest way

Start with the basics: turn the router off and on againThis clears temporary DHCP errors, clears the IP address cache, and restarts the Wi-Fi hotspot service. Here's how to properly reboot:

• 🔌 Turn off the router's power (pull the plug out of the socket or press the button Power).
• ⏳ Wait 30–60 seconds - this is enough for the capacitors to discharge.
• 🔌 Turn the router back on and wait until it fully boots up (the indicators will stop flashing).

Parallel reboot your phoneOn . Android hold down the power button and select "Reboot", on iPhone:

• 📱 iPhone 8 and newer: quickly press volume +, then volume –, hold the button Side before the Apple logo appeared.
• 📱 iPhone 7/7 Plus: hold Side + volume – before reboot.
• 📱 iPhone 6s and later: hold Home + Power.

After rebooting both devices, try connecting again. If that doesn't work, move on.

2. Check your router's Wi-Fi security settings

Sometimes the phone can't connect because incompatibility of security protocolsFor example, if the router uses WPA3, and yours Android or iOS supports only WPA2Or vice versa: an outdated device does not understand modern standards.

To check and change settings:

1. Open router web interface (enter in browser 192.168.0.1, 192.168.1.1 or look at the address on the router sticker).
2. Enter login/password (usually admin/admin or see sticker).
3. Go to the section Wi-Fi → Security Settings (or Wireless → Security).
4. Check the parameters:
   • 🔒 Security type: put WPA2-PSK (AES) - this is a universal option.
   • 📡 Channel width: if it's worth it 40 MHz, try it 20 MHz (solves problems with old phones).
   • 🔄 Wi-Fi mode: select 802.11n (or 802.11b/g/n for maximum compatibility).

Save the settings and reboot the router.

Critical detail: if enabled in the router settings WPA3 or WPA2/WPA3 Mixed, some phones (especially old ones Android up to version 10) will not be able to connect. Switch to a clean WPA2-PSK.

What are WPA2 and WPA3?

WPA2 (Wi-Fi Protected Access 2) is a security standard used since 2004. It encrypts traffic using the AES protocol and is compatible with virtually all devices. WPA3 (2018) is more secure but may not be supported by older smartphones, smart TVs, or printers.

3. Remove the network from your saved connections and reconnect.

Sometimes your phone "remembers" incorrect connection settings (for example, an old IP address or proxy settings). To reset them:

• 📱 On Android:
  1. Open Settings → Wi-Fi.
  2. Click on your network name and select "Delete" (or "Forget").
  3. Please reconnect by entering your password.

🍎 On iPhone:

1. Go to Settings → Wi-Fi.
2. Tap the ⓘ icon next to the network and select "Forget this network".
3. Please connect again.

If after this the phone still doesn't connect, try manually specify the IP address:

• 📱 On Android: in the network settings, select "Advanced" → "IP Settings" → "Static". Enter:
  • IP address: 192.168.1.X (where X is a number from 10 to 254, not occupied by other devices).
  • Gateway: 192.168.1.1 (or your router's address).
  • DNS: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).

🍎 On iPhone: in network settings, click "Configure DNS" → "Manually" and add 8.8.8.8.

Make sure DHCP is enabled on your router|Check if the selected IP is already in use by another device|Try connecting without specifying DNS (this can sometimes interfere)-->

4. Update your router firmware and phone software

Outdated software is a common cause of connection problems. Routers may contain bugs in the firmware, and phones — errors in the Wi-Fi module.

📡 How to update your router:

1. Log into your router's web interface (see section 2).
2. Find the section System → Software Update (or Administration → Firmware Upgrade).
3. Click Check for updates and, if they exist, install them.
4. ⚠️ Do not turn off the router during the update! This can lead to its "bricking".

📱 How to update your phone:

• 🤖 Android: Settings → System → Software Update.
• 🍎 iPhone: Settings → General → Software Update.

⚠️ Attention: If your router is older than 5-7 years, the manufacturer may have stopped supporting firmware. In this case, you won't be able to update it—consider purchasing a new one.

5. Check your Wi-Fi channel and interference from other networks

If the router is operating on a busy channel (for example, 6 or 11 in the 2.4 GHz range), this may cause packet loss And connection problemsThis is especially relevant in apartment buildings where many neighbors have Wi-Fi.

📊 How to choose the optimal channel:

1. Install a Wi-Fi analyzer app on your phone (for example, WiFi Analyzer For Android or AirPort Utility For iOS).
2. Look at which channels are occupied by your neighbors and choose the freest one (for example, 1, 3 or 13 for 2.4 GHz).
3. Go to your router settings and change the channel in the section Wi-Fi → Channel.

🔄 Additional settings for stability:

• 📶 If the router supports 5 GHz, try connecting to this network - it is less busy.
• 🔄 Turn on the option "Auto Channel Selection" (if there is one), so that the router itself can search for the optimal one.
• 📵 Turn off Wi-Fi Power Saving Mode in the phone settings (on Android: Settings → Wi-Fi → Advanced → Power saving mode).

6. Reset your phone's network settings

If the previous methods did not help, the problem may be in system network settings phone. Resetting will return them to factory settings, but will delete all saved Wi-Fi passwords and mobile Internet parameters.

📱 How to reset network settings:

• 🤖 Android:
  1. Settings → System → Reset → Reset Wi-Fi, mobile network, and Bluetooth settings.
  2. Confirm the action (you may be asked to enter your PIN).

🍎 iPhone:

1. Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings.
2. Enter your device password to confirm.

⚠️ Attention: After the reset, you will have to re-enter passwords for all Wi-Fi networks, as well as set up a VPN, mobile Internet APN, and paired Bluetooth devices (headphones, watches).

If resetting doesn't help, the problem may be in hardware failure of the Wi-Fi module phone. In this case, contact the service center.

7. Check MAC filtering and other router restrictions

Some routers are configured so that allow only certain devices to connect according to them MAC addressIf your phone is not on the "white list," it will not be able to connect, even with the correct password.

🔍 How to check and disable MAC filtering:

1. Log into your router's web interface.
2. Find the section Wi-Fi → MAC Filter (or Wireless → MAC Filtering).
3. If filtering is enabled (Enable), disable it or add the phone's MAC address to the list of allowed ones.

📱 How to find out your phone's MAC address:

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

🔧 Other router restrictions that may block the connection:

• 🕒 Wi-Fi schedule: check if the network is disconnected by time (Wi-Fi → Schedule).
• 👥 Connected devices limit: Some routers limit the number of gadgets (for example, 10 or 20).
• 🔒 Guest network: If you connect to a guest network, it may have its own restrictions.

8. When to contact service or replace your router

If none of the methods helped, the problem may be in:

• 📡 Router malfunctions: overheating, firmware failure or breakdown of the Wi-Fi module.
• 📱 Phone hardware defect: damage to the antenna or Wi-Fi controller (often after falls or exposure to moisture).
• 🔌 Problems with the provider: Sometimes operators block the connection of new devices (relevant for corporate networks).

🔧 What to do:

• 🔄 Try connecting your phone to another Wi-Fi network (For example, in a cafe or at a friend's place). If it doesn't connect everywhere, the problem is with the phone.
• 📡 Connect to your router another device (laptop, tablet). If it also doesn't connect, the problem is with the router.
• 🛠️ If your router is old (5+ years), consider replacing it. Modern models (for example, TP-Link Archer AX55 or ASUS RT-AX55) work better with newer phones.

⚠️ Attention: If your phone has been dropped or gotten wet, the Wi-Fi problem may be due to damage to the motherboard. In this case, repairs will be expensive (sometimes it's cheaper to buy a new device).

💡 Last piece of advice: If your router provides internet via cable but not Wi-Fi, try roll back the firmware to an older version (for instructions, see the manufacturer's website). Sometimes updates contain critical bugs.

FAQ: Frequently asked questions about Wi-Fi issues on your phone

❓ Why does my phone say "Connecting..." and then disconnect?

This is a typical sign incompatibility of security protocols (WPA2 vs WPA3) or problems with DHCP (The router doesn't assign an IP address). Try:

1. Switch the security type on the router to WPA2-PSK (AES).
2. Specify a static IP manually (see section 3).
3. Disable MAC filtering (section 7).

❓ My iPhone won't connect to Wi-Fi, even though the password is correct. What should I do?

On iPhone A common problem is a network configuration issue. This helps:

• Reset network settings (Settings → General → Transfer or reset iPhone → Reset network settings).
• Update iOS to the latest version.
• Disabling the function Private Wi-Fi Address (Wi-Fi Settings → ⓘ next to the network → Private Address).

If it doesn't help, check if it's enabled on your router. client isolation (AP Isolation), which blocks data exchange between devices on the same network.

❓ My Android sees the network but won't connect. What's wrong?

On Android The culprits may be:

• 🔄 Power saving mode, which turns off Wi-Fi in the background (Settings → Wi-Fi → Advanced → Power saving mode).
• 📱 Wi-Fi module failure (rebooting or resetting network settings helps).
• 🛠️ Custom firmware (If the phone was flashed unofficially, the Wi-Fi module may not work correctly).

Try disabling it too adaptive Wi-Fi (if available in the settings) - it automatically switches between 2.4 GHz and 5 GHz, which sometimes causes glitches.

❓ Can a virus block a Wi-Fi connection?

Theoretically yes, but in practice it is extremely rareViruses typically steal data or display ads, rather than block Wi-Fi. If you suspect an infection:

1. Check your phone with an antivirus (Malwarebytes, Dr.Web).
2. Remove suspicious applications (especially those that requested network access).
3. Reset your phone to factory settings (make a backup first).

If Wi-Fi works after this, the problem was software-related. If not, look for the cause in the router or hardware.

❓ How do I connect to Wi-Fi if I forgot my password?

If you have lost your password but still have access to your router:

1. Connect to the router via cable (or through another device where Wi-Fi is already saved).
2. Go to the web interface (192.168.0.1 or 192.168.1.1).
3. Go to Wi-Fi → Security Settings and look at the password in the field PSK password.

If you don’t have access to the router, reset it to factory settings (button Reset on the back panel) and reconfigure.
