How to update Wi-Fi on a laptop: drivers, firmware, and network settings

Weak signal, frequent connection drops, or complete lack of Wi-Fi connection are typical problems laptop owners encounter after 2-3 years of use. In 80% of cases, these problems are caused by outdated hardware. network adapter drivers, incorrect power saving settings or conflicting Wi-Fi module firmwareUpdating these components not only restores network stability, but also adds support for new standards (for example, Wi-Fi 6E or WPA3), increases data transfer speed and reduces lag in games.

In this article, we will look at all the ways to update Wi-Fi on a laptop - from automatic driver installation through Windows Update to manually reflashing the adapter using specialized utilities. We will separately cover the nuances for different operating systems (including macOS And Linux), as well as how to avoid common mistakes that can brick your laptop without network access. If you still have questions after reading this, check FAQ section at the end of the material.

1. How to determine if your laptop's Wi-Fi needs to be updated

Before updating, make sure the problem is truly software-related and not a hardware issue. Here are key signs that your Wi-Fi adapter needs attention:

• 🔌 The laptop does not see some networks, although other devices detect them.
• 🐢 Internet speed is lower than on other gadgets on the same network (check via Speedtest).
• 🔄 The connection drops periodically, especially under heavy load (for example, during 4K streaming or online gaming).
• ⚡ In the Device Manager, there is an exclamation mark next to the network adapter.
• 🔧 After updating Windows or macOS, Wi-Fi stopped working altogether.

If you recognize any of these symptoms, updating your drivers or firmware will likely help. But first, check the basic settings:

⚠️ Attention: Before any manipulations with network components, disable VPN and antivirus programs (for example, Kaspersky or Avast). They can block access to system files or create conflicts with new drivers.

Also, make sure the problem isn't with your router. Reboot it, check your channel settings (it's recommended to use 5 GHz with channel width 80 MHz for maximum speed) and update your router's firmware. If other devices are working correctly, the laptop is to blame.

2. Methods for updating Wi-Fi adapter drivers in Windows

IN Windows 10/11 There are three main ways to update network card drivers: through built-in system tools, using the laptop manufacturer's software, or manually from the official website. Let's look at each of them.

2.1 Automatic update via Device Manager

This is the simplest method, but it doesn't always provide the latest driver version. However, it's safe and doesn't require downloading files from third-party sources.

1. Click Win + X and select device Manager.
2. Expand the section Network adapters.
3. Look for devices with names like Wireless, Wi-Fi, 802.11 or chip model (for example, Intel AX200, Qualcomm Atheros QCA61x4, Realtek RTL8852AE).
4. Right click on it and select Update driver → Automatic search.

If the system finds an update, install it and restart the laptop. If not, proceed to the next method.

netsh winsock reset
netsh int ip reset
ipconfig /flushdns

This will help avoid conflicts with previous driver versions.-->

2.2. Updating via the manufacturer's official website

Laptop Manufacturers (HP, Dell, Lenovo, Asus etc.) and Wi-Fi chips (Intel, Qualcomm, Realtek, Broadcom) regularly release updated drivers with bug fixes. Here's how to find them:

1. Determine the exact model of the laptop (on the case or in the documentation) and the model of the Wi-Fi adapter (in Device Manager).
2. Go to the support website for your laptop or chip manufacturer. For example:
   • For Intel: Download Center
   • For Realtek: chapter Network on official website
   • For laptops HP: HP Support Assistant

⚠️ Attention: Never download drivers from torrents or third-party sites like DriverPack SolutionThey may contain viruses or outdated versions that will only make Wi-Fi problems worse.

After installation, restart your laptop and check your network connection. If the driver doesn't install, try uninstalling the old one. device Manager (right click → Remove device), and then install a new one.

2.3. Using specialized utilities

For users who don't want to search for drivers manually, there are utilities like Driver Booster, Snappy Driver Installer or Driver EasyThey scan the system and offer updates for all components, including the Wi-Fi adapter. However, this method has its drawbacks:

• ⚠️ Risk of installing incompatible or beta versions of drivers.
• 💰 Some programs require a paid subscription to function fully.
• 🛑 Conflicts with antivirus software are possible.

If you decide to use such a utility, create a system restore point (Win + R → rstrui) in case of failures.

Download the driver from the official website|Create a system restore point|Disable the antivirus|Connect the laptop to the network via cable (in case of loss of Wi-Fi)|Write down the current network settings (SSID, password)-->

3. Updating the Wi-Fi adapter firmware

Unlike drivers, which control the adapter's interaction with the operating system, firmware (firmware) is the built-in software of the Wi-Fi chip itself. Updating it can significantly improve performance and add support for new standards (for example, Wi-Fi 6) or fix critical vulnerabilities. However, the process is more risky: if an error occurs, the adapter may stop working altogether.

The firmware is updated only in extreme cases:

• 🔧 The manufacturer has released a patch for a critical error (for example, a vulnerability Krack V WPA2).
• 🚀 Need support for a new standard (for example, 802.11ax For Wi-Fi 6).
• 🔄 The adapter is unstable even after updating the drivers.

3.1 How to find out the current firmware version

IN Windows The firmware version can be viewed through Command line:

netsh wlan show drivers

Look for the line Version of the Firmware. IN macOS And Linux Information about the firmware can be obtained via the terminal:

For macOS:

system_profiler SPAirPortDataType

For Linux:

dmesg | grep firmware

3.2. Step-by-step instructions for updating the firmware

The process depends on the chip manufacturer. Let's look at popular adapters as an example. Intel And Realtek.

For Intel adapters (AX200, AX210, 9260, etc.):

1. Download the utility Intel PROSet/Wireless Software With official website.
2. Install it and run it Intel Driver & Support Assistant.
3. The program will automatically check for firmware updates and offer to install them.
4. Follow the wizard's instructions. Do not turn off your laptop or remove the adapter during the process, as this may damage it.

For Realtek adapters (RTL8821CE, RTL8852AE, etc.):

1. Find the chip model in Device Manager.
2. Download the firmware from Realtek website (chapter Communications Network ICs → WLAN).
3. Unzip the archive and run the file with the extension .exe or .bat.
4. Confirm the update and wait for it to complete (usually takes 1-2 minutes).

⚠️ Attention: After updating the firmware, some Wi-Fi settings (for example, network priority) 2.4 GHz/5 GHz) can be reset to factory settings. Check them in Settings → Network and Internet → Wi-Fi.

4. Updating Wi-Fi on macOS laptops

On MacBook and other laptops Apple The Wi-Fi update process is simplified thanks to an integrated ecosystem. However, there are some nuances related to the macOS version and adapter model.

4.1. Updating via System Update

Most updates for Wi-Fi adapters Broadcom (used in MacBook) come with macOS updates. To install them:

1. Open System Preferences → Software update.
2. If updates are available, install them and restart your laptop.
3. Check the firmware version via Terminal (command above).

For models with chips Intel (For example, MacBook Pro 2018-2020) manual installation of drivers may be required via Boot Camp Assistant, if you use Windows on Mac.

4.2. Resetting Network Settings on macOS

If you experience problems after updating, reset your network settings:

1. Open Terminal and run:

   sudo ifconfig en0 down
   sudo ifconfig en0 up

   (replace en0 to your interface, if it is different).

2. Remove configuration files:

   sudo rm /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
   sudo rm /Library/Preferences/SystemConfiguration/preferences.plist

3. Restart your laptop.

⚠️ Attention: On MacBook with chips Apple Silicon (M1/M2) Manual Wi-Fi firmware updates are not possible - they only happen through macOS updates. Do not attempt to use utilities for Intel-Mac, this may cause crashes.

5. Updating Wi-Fi in Linux (Ubuntu, Fedora, Arch)

IN Linux The process of updating drivers and firmware depends on the distribution and the type of adapter. Most modern kernels (kernel 5.4+) support popular chips (Intel, Realtek, Atheros) "out of the box", but sometimes manual adjustment is required.

5.1 Updating drivers via a package manager

For distributions based on Debian/Ubuntu:

sudo apt update
sudo apt install firmware-iwlwifi # for Intel
sudo apt install firmware-realtek # for Realtek

For Fedora/RHEL:

sudo dnf update
sudo dnf install iwl*-firmware # for Intel

For Arch Linux:

sudo pacman -Syu
sudo pacman -S linux-firmware

5.2. Manual firmware installation

If your adapter is not supported by the current kernel version, download the firmware from the manufacturer's official website and install it manually:

1. Download the firmware file (usually with the extension .ucode or .bin).
2. Copy it to the directory /lib/firmware/:

   sudo cp ~/Downloads/fw-file.ucode /lib/firmware/

3. Update module initialization:

   sudo depmod -a
   sudo modprobe -r iwlwifi # for Intel
   sudo modprobe iwlwifi

After rebooting, the adapter should work with the new firmware.

6. Troubleshooting after the update

Even with a proper update, problems can still arise. Here are the most common ones and how to resolve them:

ipconfig /release
ipconfig /renew

If none of these methods help, check the hardware. Open the laptop lid and make sure the Wi-Fi antennas are connected to the adapter (they look like two thin wires). Sometimes they become disconnected due to drops or overheating.

7. Optimizing Wi-Fi after the update

Updating drivers and firmware is only half the battle. To maximize Wi-Fi performance, adjust the following settings:

• 📶 Frequency selection: Set it in your router settings 5 GHz for speed or 2.4 GHz for range. Modern adapters (for example, Intel AX210) support both ranges simultaneously.
• 🔋 Energy saving: IN Control Panel → Power Options → Change Plan Settings → Advanced Settings set for Wireless network adapter settings meaning Maximum performance.
• 🔒 Safety: Use encryption WPA3 instead of the outdated one WPA2 (if the router supports it).
• 📡 Channel and width: In the router settings, select the least loaded channel (for example, 36 or 149 For 5 GHz) and width 80 MHz for maximum speed.

It is also useful to update IPv6 protocol, if your provider supports it. To do this, Settings → Network → Wi-Fi → Configure adapter settings open the protocol properties IPv6 and check the box Obtain DNS server automatically.
