What's the cause, and how can you fix it?

The problem could be in the router settings or the phone itself. Sometimes the provider is to blame, less often it's a hardware issue. In this article, we'll look into the matter. all possible reasons, Why Wi-Fi works on the computer, but doesn't work on the phone, and we'll give step-by-step instructions Troubleshooting. We'll start with the simplest solutions and gradually move on to more complex ones.

If you're unsure of your technical skills, don't worry: most of the methods don't require in-depth knowledge. The key is to follow the instructions carefully and don't skip steps.

1. Restarting devices: why does it work?

It sounds trivial, but in 30% of cases, the problem is resolved with a simple reboot. The problem is that both the router and the phone can freeze at the software level. For example, DHCP server the router may not display correctly IP addresses, and the phone will not process them correctly.

How to reboot correctly:

  • Router: Unplug it from the power outlet for 30 seconds, then plug it back in. Wait for it to fully boot up (usually 1-2 minutes).
  • 📱 Telephone: turn it off for 1 minute, then turn it on. Android hold down the power button, iPhone - Press and hold the side button and volume control.
  • 💻 Computer: Restart it, even if the internet is working there. Sometimes the PC clogs up the connection.

After restarting all devices, try connecting to Wi-Fi again. If the issue persists, proceed to the next step.

2. Checking the Wi-Fi range: 2.4 GHz vs. 5 GHz

Modern routers support two frequency ranges: 2.4 GHz And 5 GHzSometimes the phone doesn't see the network or doesn't connect to it because:

  • 📶 The router is configured only for 5 GHz, and the phone only supports 2.4 GHz (relevant for older smartphones).
  • 🔄 The network is split (there are two access points with the same name, but different frequencies), and the phone is "latching" to the non-working one.
  • 🚫 One of the ranges is disabled in the router settings.

How to check and fix:

  1. Go to the router settings through a browser on your computer (usually the address 192.168.0.1 or 192.168.1.1, login and password - on the sticker on the back of the device).
  2. Find the section Wi-Fi or Wireless network.
  3. Check if both ranges are enabled (2.4 GHz And 5 GHz). If not, turn it on.
  4. If the networks are separate, try connecting to each one in turn.

If your phone is older than 5 years, it most likely does not support 5 GHzIn this case:

  • Turn it off 5 GHz in the router settings.
  • Or rename the networks to 2.4 GHz And 5 GHz had different names (for example, MyWiFi_2G And MyWiFi_5G).

3. IP and DNS settings: why doesn't the phone receive an address?

If your phone connects to Wi-Fi, but the internet doesn't work (the Wi-Fi icon is active, but the pages don't load), the problem may be IP or DNS settingsThe computer may automatically receive the correct parameters, but the phone may not.

How to check for Android:

  1. Go to Settings → Wi-Fi.
  2. Click on your network and select Change network (or Additionally).
  3. Check the parameters IP:
    • If it's worth it DHCP (automatically), try specifying it manually IP.
    • If it is static IP, try switching to DHCP.

For iPhone:

  1. Go to Settings → Wi-Fi, click on i near your network.
  2. In the section DNS try to specify 8.8.8.8 (Google DNS) or 1.1.1.1 (Cloudflare DNS).

If you're not sure what settings to specify, try these:

Parameter Meaning (example)
IP address 192.168.0.100 (the last digit is any number from 100 to 200)
Gateway 192.168.0.1 (usually like a router)
Subnet mask 255.255.255.0
DNS 1 8.8.8.8
DNS 2 8.8.4.4
How to find out a router's IP address from a computer?

On Windows open command prompt (Win + R → cmd) and enter

ipconfig
. Look for the line Main gateway - this is the router's IP.

4. MAC address conflict: why is the router blocking the phone?

Some routers have a feature MAC address filteringIf it is enabled, the router will only allow devices whose MAC addresses are whitelisted. Your computer may be on the whitelist, but your phone isn't.

How to check and fix:

  1. Find out MAC address phone:
    • On Android: Settings → About phone → General information → Wi-Fi MAC address.
    • On iPhone: Settings → General → About → Wi-Fi Address.
  • Go to your router settings (as in the previous steps).
  • Find the section MAC filter or Access control.
  • If the filter is enabled, add MAC address phone to the list of allowed devices.
  • Also check if the feature is enabled Blocking unknown devices or Connection protectionSometimes it triggers falsely.

    ☑️ MAC filter check

    Completed: 0 / 5

    5. Problems with the router or phone firmware

    If all the previous steps did not help, the problem may be in router firmware or By phoneOutdated software often leads to conflicts, especially if the router or phone hasn't been updated in a while.

    For router:

    • 🔄 Check the firmware version in the settings (section System or Update).
    • 📥 If there is a new version, update it. Do not turn off the router during the update!
    • ⚠️ If you have a router from a provider, updating may reset the settings. Write down your connection settings in advance.

    For phone:

    • 📱 On Android: Settings → System → System Update.
    • 🍎 On iPhone: Settings → General → Software Update.
    • 🔄 If an update is available, install it.

    If the problem persists after updating, try reset network settings on the phone:

    • 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.

    6. Hardware malfunctions: when is it time to take it in for repair?

    If none of the methods helped, the problem may be in hardwareHere are some signs that the problem is in the hardware:

    • 📵 The phone doesn't detect it not a single one Wi-Fi network (even in other places).
    • 🔌 Wi-Fi turns on, but immediately turns off.
    • 🔥 The phone overheats when trying to connect.
    • 🛠️ Artifacts appear on the screen or the smartphone spontaneously reboots.

    What could have broken:

    Component Signs of malfunction Cost of repairs (approximately)
    Wi-Fi module It doesn't see the network and only connects when near the router. 1 500 — 4 000 ₽
    Wi-Fi antenna Weak signal, frequent interruptions 1 000 — 3 000 ₽
    Power controller Wi-Fi turns off when battery is low 2 000 — 5 000 ₽

    If you suspect a hardware problem:

    1. Try connecting to a different Wi-Fi network (for example, at a cafe or at a friend's place).
    2. Check if it works Bluetooth And mobile InternetIf not, the problem is in the communication module.
    3. Please contact the service center. iPhone It is better to choose an authorized one, for Android — with good reviews.

    7. Problems on the provider's side: what to do?

    It's rare, but it can happen that the problem lies with your internet provider. For example:

    • 📡 The provider has limited the number of connected devices (sometimes the tariff indicates "1 device").
    • 🔒 Protection against "unnecessary" connections is enabled on the line (relevant for corporate plans).
    • 🔄 The provider is carrying out technical work, but it only affects certain types of devices.

    How to check:

    1. Call your provider's support team and check if there are any restrictions on the number of devices.
    2. Ask if connections from phones are blocked (sometimes this is done to save traffic).
    3. Ask to reset the session on your account (sometimes it helps).

    If your provider has confirmed the restrictions, you have two options:

    • 💰 Purchase a more expensive plan with an unlimited number of devices.
    • 📶 Use your phone as a Wi-Fi repeater (if your computer is connected via cable).
