Wi-Fi works on my phone but won't connect to my computer: A complete troubleshooting guide

On a Windows computer Wi-Fi won't connect or shows "No Internet Access" error, even though your phone, tablet, and other devices successfully access the network through the same router? In most cases, the problem lies not with the hardware, but with local failures: a disabled adapter, outdated network card drivers (especially after an OS update), IP address conflicts, or incorrect TCP/IP protocol settings. Before rebooting the router or calling your ISP, check the Wi-Fi indicator on your laptop (is it lit?), run network diagnostics in Windows, and make sure there's no exclamation point next to the wireless adapter in Device Manager—this will point to the specific cause of the problem.

This article will help you understand why this happens and what to do if Wi-Fi is available on your phone, but not on your laptop or desktop PC.We'll cover both simple solutions (rebooting the hardware) and complex cases (manual DNS configuration, resetting the TCP/IP stack). All instructions are relevant for Windows 10/11, but some of the methods are also suitable for macOS or Linux.

Before you begin your diagnosis, answer two key questions: 1. Does your computer see your Wi-Fi network name in the list of available networks? 2. Is the error "Unable to connect to this network" or "Limited access»?

The answers determine whether the problem you're experiencing is hardware (failed adapter), software (driver failure), or network-related (incorrect router settings). We'll look at each scenario separately below.

1. Checking basic parameters: router, adapter, cables

Start with basic steps—they help in 30% of cases when the problem is caused by a temporary hardware or network failure.

• 🔄 Reboot your router. Unplug it for 30 seconds, then plug it back in. Wait until it boots up completely (the indicators should be steady).
• 💻 Restart your computer. Especially if the problem appeared after updating Windows or installing new software.
• 📡 Check your Wi-Fi adapter. Laptops usually have a physical button or key combination (eg. Fn + F2) to enable/disable the module. On your PC, make sure the adapter is connected to a USB port (if external).
• 🔌 Rule out nutritional problems. If you are using a USB Wi-Fi adapter, try connecting it to a different port or through a powered USB hub.

If Wi-Fi works after rebooting the router, the problem was a temporary DHCP server outage or the device overheating. In this case, it is recommended update the router firmware (instructions are usually available on the manufacturer's website).

2. Diagnosing a Wi-Fi adapter in Windows

If the network doesn't appear in the list or your computer can't connect to it, check the status of your network adapter.

Open device Manager (click Win + X → select the appropriate item). In the section Network adapters Find a device with names like: Wireless, Wi-Fi, 802.11ac or Dual Band. Pay attention to the icons:

• ⚠️ Yellow exclamation mark — the driver is installed incorrectly or is in conflict.
• 🔴 Red cross — the adapter is disabled.
• 🔄 Arrows in a circle — Windows is trying to install the driver.

If the adapter is disabled, right-click on it and select EngageIf you have problems with the driver:

1. Right-click on the adapter → Update driver → Automatic search.
2. If that doesn't help, download the driver from the manufacturer's website (for laptops, from the model support website; for USB adapters, from the brand's website, for example, TP-Link or ASUS).
3. Uninstall the current driver (Remove device in the Manager), then restart your PC - Windows will try to install it again.

3. Configuring network settings in Windows

If the adapter works but the connection is missing or limited, check your network settings.

Open Parameters (Win + I) → Network and Internet → Wi-FiMake sure that:

• 🔘 Wireless network is on (slider in the "On" position).
• 🔍 Your network is displayed in the list. (if not, the problem is in the router or adapter).
• 🔒 The password is entered correctly. (Sometimes reconnecting by deleting the network helps: click on its name → Forget).

If the network connects but there is no internet connection (“No network access" or "Limited"), follow these steps:

1. Open Command line as administrator (Win + X → Terminal (Administrator)).
2. Enter the commands one by one:

   netsh winsock reset
   netsh int ip reset
   ipconfig /release
   ipconfig /renew
   ipconfig /flushdns

   After each press Enter.

3. Restart your computer.

Critical detail: If after resetting TCP/IP the problem persists and errors like "DHCP lease failed" appear in the router logs, try manually setting the IP address. To do this:

1. Open Control Panel → Network and Internet → Network and Sharing Center → Changing adapter settings.
2. Right click on Wireless network → Properties → Internet Protocol version 4 (TCP/IPv4).
3. Select Use the following IP address and enter: IP address: 192.168.1.100 (or another free one in your subnet), Subnet mask: 255.255.255.0, Main gateway: 192.168.1.1 (router address), DNS: 8.8.8.8 and 8.8.4.4 (Google DNS).

4. Checking router settings

If Wi-Fi works on your phone but not on your PC, the router settings may be to blame and block connections for certain devices.

Go to the router's web interface (usually at 192.168.1.1 or 192.168.0.1, login/password — admin/admin or indicated on the device sticker). Check the following parameters:

Pay special attention Wi-Fi channel. If selected in the router settings Auto, try specifying the channels manually 1, 6 or 11 (for 2.4 GHz) - they are less susceptible to interference. For 5 GHz, select channels 36–48 or 149–165.

5. Software conflicts

Antivirus software, VPN clients, and even standard Windows updates can block Wi-Fi access. If the problem occurred after installing new software, check the following:

• 🛡️ Antivirus/firewall. Temporarily disable protection (for example, in Kaspersky or Avast) and try connecting again. If it works, add the network to the exceptions.
• 🌐 VPN services. Programs like NordVPN or ProtonVPN Network routes may change. Disable your VPN and check your connection.
• 🔄 Windows updates. After major updates (for example, Windows 11 23H2) network settings may be reset. Try rolling back the update (Settings → Windows Update → Update history → Uninstall updates).
• 🎮 Game clients. Steam, Epic Games or Origin Sometimes they take up the entire communication channel. Close them before connecting.

If you suspect a specific program, check its impact through Task Manager (Ctrl + Shift + Esc):

1. Open the tab Net.
2. Sort processes by network load.
3. If an application is consuming a suspiciously large amount of traffic, close it and reconnect to Wi-Fi.

6. Hardware problems: when nothing helps

If all the previous steps have not yielded results, the problem may be in physical malfunction Wi-Fi adapter or router.

How to check this:

• 🔧 Test on another device. Connect another PC or laptop to the router. If the Wi-Fi works, the problem is with your computer.
• 📱 USB adapter. Buy or borrow an external Wi-Fi adapter (e.g. TP-Link TL-WN725N). If the network works with it, the built-in module is to blame.
• 🔌 Direct connection. Connect your PC to the router via an Ethernet cable. If you have internet access, the problem is definitely with the wireless module.

Typical hardware faults:

• 🔥 Adapter overheating (relevant for laptops - try cooling the device).
• ⚡ Nutritional problems (The USB adapter may not provide enough current - use a powered hub).
• 📡 Damage to antennas (on the router or PC - check the integrity of the connectors).

If the adapter is faulty, it will need to be replaced. For laptops, this may be a built-in module (e.g., Intel AX200), for a PC - a PCIe card or USB dongle. Average replacement cost: 1 500–3 000 ₽ (depending on the model).

7. Alternative connection methods

If you can't fix your Wi-Fi problem, but you urgently need internet, try these alternative methods:

• 📶 Modem mode on the phone. Turn on Access point in your smartphone settings and connect to it from your PC.
• 🔌 Powerline adapters. Devices like TP-Link AV600 transmit the Internet through electrical wiring - connect one adapter to the router, the other to the PC.
• 🖥️ Ethernet cable. Run a wire from the router to the computer (even temporarily).
• 🔄 USB terminal. Some smartphones (eg. Samsung with function Link to Windows) can distribute the Internet via USB.

If you frequently encounter Wi-Fi problems, consider purchasing Mesh systems (For example, Google Nest Wi-Fi or ASUS ZenWiFi). It provides more stable coverage due to multiple access points.

FAQ: Frequently Asked Questions

If none of the methods help, contact a specialist to diagnose the hardware of your PC or router. In rare cases, the problem may lie in incompatibility of Wi-Fi standards (for example, the router only works in the mode 802.11ac, and the adapter only supports 802.11n).
