3. The phone connects to Wi-Fi, but the internet doesn't work.

Situation: Your phone connects successfully to the network (the Wi-Fi icon is active), but pages won't load, messaging apps don't work, and you see the "No internet access" error instead of websites. The cause could be on the phone, the router, or your ISP.

First, check the following points:

• 🌐 Does the internet work on other devices?If so, the problem is with your phone. If not, it's with your router or ISP.
• ⚙️ Is DHCP configured correctly on the router?? If it is written manually IP, DNS or gateway, the phone may not be able to access the network.
• 🔗 Is your antivirus or firewall blocking access?? On Android, check the settings of apps like Avast or Kaspersky.
• 📡 Are your DNS settings corrupted?Sometimes providers or routers provide incorrect DNS servers.

Diagnostic instructions:

1. Check the IP settings on your phone:
   • On Android: Settings → Wi-Fi → [your network] → Advanced → IP settings. Make sure it's worth it. DHCP (automatic IP acquisition).
   • On iPhone: Settings → Wi-Fi → [your network] → Configure DNS → Automatic.
2. Try manually entering DNS:
   • Use public DNS, for example, 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
   • On Android This is done in the same IP settings (select Statically and enter DNS).

• Go to the router's web interface and make sure it's enabled. DHCP server.
• Check if the feature is enabled Isolation of clients (it can block internet access for new devices).

⚠️ Attention: If the problem appeared after updating the phone firmware (especially on Android 14 or iOS 17), check the support forums for your model. In some cases, rolling back to a previous software version or waiting for a patch from the manufacturer can help.

4. Problems connecting to public networks (cafes, airports, hotels)

Public Wi-Fi networks often have additional restrictions, such as portal authentication (requiring you to enter your login/password on the page), MAC address restrictions, or operating time limitations. If your phone connects but you can't access the internet, you likely need to:

• 📱 Open your browser and accept the terms of use.Many networks require confirmation through portal capture (you'll see a page with a "Connect" or "Accept" button).
• 🔄 Refresh the page or open it in another browserSometimes Safari/Chrome does not redirect to the authentication portal.
• 🛡️ Disable VPNSome public networks block VPN connections.
• ⏳ Wait 1-2 minutesConnection may be delayed in hotels or airports.

If you see the message "Connected, no internet access":

• Try opening the address manually. 1.1.1.1 or neverssl.com - this often triggers the authentication process.
• On Android Check if "Avoid poor connections" mode is enabled in your Wi-Fi settings.
• Make sure the time and date on your phone are set correctly (some networks check this).

5. Problems connecting to 5 GHz Wi-Fi

The 5 GHz network offers faster speeds, but has a smaller coverage area and may not be compatible with older devices. If your phone doesn't see the 5 GHz network or connects but the connection is unstable:

• 📶 Check if your phone supports 5 GHz. In older models (for example, iPhone 5s or Samsung Galaxy S4) can only be 2.4 GHz.
• 🔄 Make sure 5 GHz is enabled in your router settings.Some routers disable this frequency by default.
• 📡 Change the 5 GHz channel. Channels 36–48 usually work more stably than 149–165 (which may require DFS support).
• 📱 Check your phone settingsOn some Android- devices in the Wi-Fi settings have an option called “Frequency range” - select Auto or 5 GHz.

If your phone connects to 5 GHz, but the connection keeps dropping:

• Try reducing the channel width in the router settings (for example, with 80 MHz on 40 MHz).
• Make sure your phone and router are within line of sight (walls and obstacles weaken the 5 GHz signal even more).
• Update your router firmware—older versions may have bugs with 5 GHz support.

6. Hardware malfunctions: when is it time for service?

If you've tried all the tips and your phone still won't connect to Wi-Fi, there may be a hardware issue. Here are some signs that it's time to take your phone to a service center:

• 🔌 The phone doesn't see it not a single one Wi-Fi network, including public ones, and other devices see them.
• 📵 Wi-Fi turns on but then turns off immediately (or the icon flashes and disappears).
• 🔥 The phone overheats when trying to connect to Wi-Fi.
• 🛠️ The problem appeared after a fall, exposure to moisture, or repairs..

What could have broken:

• Wi-Fi module — the most common malfunction. Replacing it costs 1,000–3,000 rubles (depending on the phone model).
• Wi-Fi antenna - may oxidize or come off after falling.
• Wireless controller — a more serious breakdown, often requiring replacement of the motherboard.

Before going to the service center:

• Make a backup copy of your data (in case you need to reset or replace the board).
• Check if your phone is still under warranty (if it is under warranty, do not open it yourself!).
• Check with the service center if they work with your model (some workshops do not take on rare brands like Nothing or Fairphone).

⚠️ Attention: If the phone stopped seeing Wi-Fi after unofficial firmware (for example, through TWRP or Magisk), the problem may be due to corrupted drivers. In this case, only updating to the official firmware version will help.
