Why Wi-Fi Works on My Phone but Won't Connect to My Computer – A Complete Guide

On a laptop or PC Wi-Fi won't connect or is unstable, even though the smartphone or tablet connects to the same network with full internet access without any problems, the problem is most often related to network card drivers, incorrect router settings (for example, encryption type or 2.4/5 GHz frequency range), IP address conflicts, or outdated connection protocols. The error may appear on Windows 10/11, macOS or Linux, regardless of the device model - be it TP-Link Archer C6, ASUS RT-AX88U or budget Keenetic Lite, - and also be accompanied by messages like "No internet access", "Connection is limited" or endless IP acquisition. The first thing to check is whether Wi-Fi is working on other devices, whether the adapter drivers are updated, and whether an antivirus or firewall is blocking the connection.

In this article we will look at All possible scenarios why a computer can't see Wi-Fi or connect to the network, while everything works on the phoneYou'll learn how to diagnose the problem, which router settings to check first, and what to do if standard tips don't help. We'll pay special attention to cases where the network is visible, but does not connect, or when There is a connection, but there is no internet (icon "No network access").

1. Problems with the Wi-Fi adapter drivers on your computer

The most common reason why Wi-Fi not working on PC, but it functions properly on the phone - incorrect, outdated or missing drivers Network adapter. Unlike smartphones, where drivers are updated automatically along with the firmware, on computers they have to be managed manually.

How to check:

• 🔧 Open device Manager (click Win + X → select an item).
• 🔍 Expand the tab Network adapters and find the device with the names Wireless, Wi-Fi or 802.11 (For example, Intel Wi-Fi 6 AX200, Qualcomm Atheros QCA9377).
• ⚠️ If a yellow exclamation mark is lit next to the adapter, the driver is not working properly.
• 🔄 Right-click on the adapter → Update driver → Automatic search.

What to do if automatic updating doesn't help:

1. Download the driver from official website of the adapter manufacturer (not a laptop!) To do this, find out the exact model through Properties → Details (field Equipment ID).
2. Uninstall the current driver via device Manager (right click → Remove device), then restart your PC and install the downloaded driver.
3. If the adapter is built-in (for example, in a laptop Lenovo or HP), check the drivers on the laptop manufacturer's website.

2. Incompatibility of Wi-Fi standards: 2.4 GHz vs. 5 GHz

Many modern routers broadcast in two ranges at once: 2.4 GHz (old standard, but with a longer range) and 5 GHz (faster, but with a shorter range). Smartphones usually automatically connect to the optimal range, and computers may "not see" one of them for the following reasons:

How to check what range your adapter supports:

1. Open Command line (Win + R → enter cmd).
2. Run the command:

   netsh wlan show drivers

3. Find the line Supported radio typesIf there is. 802.11a — the adapter supports 5 GHz.

3. MAC address restrictions or device filtering

Some routers (especially corporate ones or with firmware like DD-WRT) have a function MAC address filtering. If specified in the settings white list If you add a MAC address to the list of allowed devices, your computer simply won't be able to connect, even if the network is visible. However, a smartphone whose MAC address is on the list will work without any issues.

How to check:

• 📱 Go to your router's control panel (usually at 192.168.0.1 or 192.168.1.1).
• 🔒 Find the section Wireless → MAC Filter (or Wireless Mode → MAC Filter).
• 📋 Check if filtering is enabled and which addresses are allowed/blocked.

How to add a computer to the whitelist:

1. Find out the MAC address of your computer's Wi-Fi adapter:

   ipconfig /all

   (look for the line Physical address in the block Wireless network adapter).

2. Copy the address (example: 00-1A-2B-3C-4D-5E) and add it to the list of allowed devices on the router.
3. Save the settings and reboot the router.

What should I do if the MAC filter is disabled, but I still can't connect?

Check if the feature is enabled AP Isolation (or Isolation of clients) in the router settings. It blocks devices on the same network from communicating with each other, which can interfere with the connection of new devices. Disable it in the section Wireless Settings or Advanced.

4. Incorrect IP and DNS settings

If your computer connects to Wi-Fi, but the internet doesn't work (icon "No network access" or "Limited"), the problem may lie in incorrect network settingsThis often occurs after manually changing settings or a failure in the router's DHCP server.

How to diagnose:

• 🖥️ Open Network parameters (Win + I → Network and Internet).
• 🔧 Choose Wi-Fi → Managing known networks → click on your network → Properties.
• 📄 Scroll to the section IP settings and check if it's worth it Obtain an IP address automatically.

If settings are manual:

1. Write down the current IP, mask, gateway and DNS values ​​(in case of a rollback).
2. Return everything to automatic mode (Obtain IP/DNS automatically).
3. Restart your computer and router.

If automatic mode does not work:

• 🔄 Enter the IP address manually (e.g. 192.168.1.100, if the router 192.168.1.1).
• 🌐 Specify DNS from Google (8.8.8.8 And 8.8.4.4) or Cloudflare (1.1.1.1).
• 🔒 Save and check the connection.

5. Hardware problems: adapter, antenna or interference

If Wi-Fi doesn't work on any computer., but it functions stably on phones, the problem may be in physical damage to the adapter, a weak signal, or external interference. Here's what to check:

Signs of hardware problems:

• 📶 The network appears and then disappears (especially when moving the laptop).
• 🔌 Wi-Fi only works near the router.
• 🚫 In Device Manager The adapter is displayed with an error (code 10, 43, etc.).

Diagnostic methods:

1. Check the antennas: on desktop PCs, external Wi-Fi adapters (for example, TP-Link TL-WN725N) are often connected via a USB extension cable. Make sure the antenna is undamaged and positioned vertically.
2. Test on another device: Connect the adapter to another PC or laptop. If the problem persists, the adapter is faulty.
3. Check for interference: Microwaves, cordless phones, and even neighboring Wi-Fi networks on the same channel can jam the signal. Use the utility Wi-Fi Analyzer (For Android) or inSSIDer (For Windows) to find a free channel.

Check the physical connection of the adapter (USB/PCIe)

Update your drivers to the latest version

Test the adapter on another device

Change the Wi-Fi channel in your router settings.

Check for interference from other devices-->

6. Conflict with antivirus or firewall

Security programs (eg Kaspersky, Avast, ESET NOD32) sometimes block network connections, considering them suspicious. The built-in Windows Firewall, especially after system updates.

How to check:

• 🛡️ Temporarily disable your antivirus and try connecting to Wi-Fi.
• 🔥 Open Windows Firewall (Control Panel → System and Security) and check if the network is blocked.
• 🔍 In the firewall log (Firewall Monitor) find records of network activity being blocked.

How to fix:

1. Add your Wi-Fi network to Trusted networks in the antivirus settings.
2. In Windows Firewall, create a rule to allow traffic for the protocol UDP at the ports 67 And 68 (DHCP).
3. If you use VPN (For example, NordVPN or ProtonVPN), disable it - sometimes VPN clients conflict with Wi-Fi connections.

7. Windows-specific issues: services, network profiles, power saving

Windows 10 And Windows 11 have a number of features that can interfere with stable Wi-Fi operation. Here are the most common ones:

1. Disabled services:

• 🔄 Check if the services are running:

  WLAN AutoConfig Service

  Network connections

  (open services.msc, find them in the list and set the startup type Automatically).

2. Incorrect network profile:

• 📋 Windows can assign a network status Publicly available, restricting access. Change it to Private:

  Settings → Network & Internet → Wi-Fi → Manage known networks → [your network] → Properties → Network Profile

3. Energy saving:

• ⚡ Windows may turn off the Wi-Fi adapter to save power. Disable this feature:

  Device Manager → Network Adapters → [your adapter] → Properties → Power Management → Uncheck "Allow the computer to turn off..."

What should I do if Wi-Fi stops working after a Windows update?

Reset network settings to factory defaults:

1. Open Settings → Network & Internet → Status → Network reset.
2. Click Reset now and confirm.
3. After restarting your PC, reconnect to Wi-Fi (you will need to enter the password).

This method helps in 70% of cases after major system updates.

FAQ: Frequently asked questions about the problem
