To do this, right-click the unknown device, select "Properties," go to the "Details" tab, and select "Hardware ID" from the list. The copied string can be used to search for a driver online.
Automatic update via Device Manager
The easiest and safest update method is to use Windows' built-in functionality. The operating system has access to a vast database of Microsoft-certified drivers. This method is ideal for users who prefer automated solutions and don't want to search for files manually.
To start the process, return to Device Manager and locate your wireless adapter. Right-click on it and select Update driverIn the window that appears, select the option Automatic driver searchThe system will contact Microsoft servers and, if a newer version is found, will download and install it.
⚠️ Note: Automatic search doesn't always find the latest driver version released by the chip manufacturer. Windows often offers a stable, but not the latest, build. If the issue persists, manual installation will be required.
In some cases, the system may report that the most suitable drivers are already installed, but the Wi-Fi problem persists. In this case, it might be worth trying to uninstall the device. Select Remove device in the context menu, confirm the action, and restart the laptop. Upon startup, Windows will attempt to reinstall the driver, which sometimes resolves software conflicts.
☑️ Check before updating
Download drivers from the official Acer website
The most reliable source of software is the manufacturer's official support website. This is where versions tested for compatibility with specific Acer laptop models are located. Using third-party resources carries the risk of malware infection or the installation of unstable builds.
Go to the Acer support page and enter your laptop's serial number or select the model from the list. The serial number is usually located on a sticker on the bottom of the device or under the battery. Once you reach the support page for your model, select the tab Drivers and Manuals, then specify the operating system version.
In the list of available files, find the section related to network hardware (Network, WLAN, Wireless). Download the file corresponding to your adapter. Note the release date and version of the file. Installation is performed by running the downloaded executable file. .exe and follow the instructions of the installation wizard.
| Driver type | Source | Advantages | Flaws |
|---|---|---|---|
| From the Acer website | Official website | Guaranteed compatibility | It may not be the newest version. |
| Windows Update | Microsoft Servers | Automation and simplicity | Often outdated versions |
| Intel/Realtek website | Chip manufacturer's website | The latest updates | Risk of conflict with laptop software |
Installing drivers from the chipset manufacturer
Sometimes laptop manufacturers fail to release updates for their devices, while chipset developers (Intel, Realtek) have already released new software versions. In such cases, you can use official utilities from the hardware manufacturers. This is especially true for Intel adapters, which are often installed in Acer laptops.
For owners of laptops with Intel modules, there is a utility Intel Driver & Support AssistantIt automatically scans the system, detects the versions of installed components, and offers the latest updates directly from the Intel website. This allows you to get the latest security fixes and performance improvements that haven't yet made it to the Acer website.
When using drivers from the chipset vendor, it's important to exercise caution. Generic drivers may not take into account the specific implementation features of the wireless module in a specific laptop model, such as antenna management or power saving. If, after installing such a driver, the laptop begins to discharge quickly or the Wi-Fi becomes unstable,
It is recommended to roll back the driver. To do this, in the adapter properties, on the "Driver" tab in Device Manager, click the button Roll backThis will revert the system to the previous working version.
Solving common Wi-Fi problems
Even after updating drivers, connection issues may persist due to incorrect power settings or protocol conflicts. The operating system often tries to save power by disabling the wireless module, which leads to connection drops. Conflicts between WPA2 and WPA3 security standards can also occur.
To prevent the system from turning off the Wi-Fi adapter, open Device Manager, go to the properties of your wireless adapter and select the tab Power managementUncheck the box. Allow the computer to turn off this device to save powerThis action will force the module to run in constant mode, which can improve connection stability.
Another effective method is to reset network settings. In Windows 10 and 11, this can be done through the Settings menu: Network and Internet → Advanced network settings → Network resetThis operation will reinstall all network adapters and return network settings to default values, which often resolves software errors.
⚠️ Note: After resetting your network, you'll need to re-enter the passwords for all Wi-Fi networks you've previously connected to. Make sure you remember your access keys or have access to them on other devices.
If all else fails, check your router settings. Try changing the wireless channel or channel width in the router settings. Sometimes interference from neighboring networks or household appliances can affect signal quality, and no driver update will help without adjusting the hardware settings.
Checking the result and diagnostics
After completing all the steps, you should verify that the update was successful and the issue is resolved. The first indicator is the absence of warning icons in Device Manager. The adapter should display correctly, without yellow triangles or question marks.
Test your connection speed and stability in practice. Try downloading a large file or streaming a high-definition video. Pay attention to your ping in online games or when using the command ping in the command line. A stable ping without packet loss indicates the driver is working properly.
It's also worth checking the installed driver version to ensure the system is using the latest version. In the adapter properties, on the "Driver" tab, compare the date and version with the ones you downloaded. If the versions match and Wi-Fi is working reliably, the process is complete.
What should I do if Wi-Fi disappears completely after an update?
If the wireless network connection disappears after updating the driver, you should roll back the driver using Device Manager. If this doesn't help, uninstall the device completely, restart the laptop, and let Windows install the basic driver automatically. As a last resort, use a system restore point.
Is it possible to update Wi-Fi drivers without the Internet?
Yes, this is possible. You'll need to download the driver on another device (computer or smartphone) and transfer it to your Acer laptop via a USB cable or flash drive. You can also use a wired Ethernet connection if your laptop has a suitable port.
Do I need to remove the old driver before installing the new one?
In most cases, the installer will automatically replace the old files. However, if conflicts or errors occur, it is recommended to completely uninstall the current driver through Device Manager (checking "Delete driver software") before installing the new version.
Does updating drivers affect Wi-Fi speed?
Yes, new drivers often contain optimizations to signal processing algorithms and support for new encryption standards, which can positively impact connection speed and stability, especially in busy environments.
