Hi

Welcome to Microsoft community.

If your Realtek WiFi USB adapter is not working, there are several steps you can take to diagnose and potentially fix the issue. Here's a structured approach:

1. Try a Different USB Port

First, ensure the problem is not with the USB port itself. Try plugging the adapter into a different USB port, preferably one directly on your computer rather than through a hub.

2. Check Device Manager

• Check for Recognition: Go to Device Manager (right-click on the Start button and select Device Manager) and see if the Realtek adapter is listed under Network adapters. If it's listed with a yellow exclamation mark, there's a driver or device issue.
• Update Driver: Right-click on the Realtek WiFi adapter and select "Update driver". You can search automatically for updated driver software. If Windows doesn't find a new driver, try looking on the Realtek website for drivers.
• Uninstall and Reinstall: If updating doesn't work, try uninstalling the device (right-click > Uninstall device) and then restart your computer. Windows should attempt to reinstall the driver upon reboot.

3. Disable and Re-enable the Device

In the Device Manager, right-click on the Realtek adapter and disable it, then right-click again and enable it. This can sometimes kickstart the adapter into working.

4. Use the Troubleshooter

Windows has a built-in troubleshooter for network issues. Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters and run the Internet Connections troubleshooter.

5. Manually Install Drivers

If the automatic update doesn’t work, you can manually download the latest drivers from the Realtek website and install them. Make sure to choose the drivers that match your specific Realtek WiFi adapter model and your version of Windows.

6. Check Power Management Settings

In Device Manager, right-click on the Realtek adapter > Properties > Power Management tab. Uncheck "Allow the computer to turn off this device to save power."

7. Test on Another Computer

If possible, test the USB adapter on another computer to determine if the issue is with the adapter itself or your computer.

If, after trying these steps, your Realtek WiFi USB adapter still isn't working, it could be a hardware fault with the adapter. You might need to consider getting a replacement or contacting technical support for further assistance.

Please feel free to let me know how it goes.

If you know your Realtek chip model get your drivers from here, and you are right never use a 3rd party driver update app/program.

The link is direct to network drivers on the Realtek site.

Communications Network ICs-通訊網路 ICs or if you want their full site Realtek

(Sorry, BryceSor, I had to unmark your answer. You did find the correct source for Realtek drivers, it's just that I had perhaps misstated the problem!)

I thought others might be interested in this update to the problem.

First, I hesitated to download any other driver, because unless the new one had a more recent date than the one I just installed from Microsoft Update, it would just be allowing the Microsoft version to be installed again.

So in the interim, I did some more testing. It's really weird what Realtek seems to have done.

In the past, the signal strength symbol (on the right side of the taskbar) indicated signal strength. If it fluctuated, it used to indicate poor signal, making you reorient the antenna or opt for a signal repeater.

Best I can tell, by doing speed tests and browsing in general, that same signal strength meter has been repurposed. It now shows bit rate being transferred, at that instant. Start a new speed test, it shows what used to represent a strong signal. Speed test ends, suddenly the symbol drops way down, implying a really awful WiFi signal.

To double-check this theory, I moved my PC from the 5 GHz band, which I typically use, to the 2.4 GHZ band, expecting to see the signal strength symbol to show full strength. But no, it too was showing this odd behavior, where it represents transfer rate as opposed to signal strength.

I don't like this one bit.

(Another problem Microsoft caused in the past couple of days, spell check no longer works on Edge. The new Edge update seems to have removed the suggested correct spellings, when a word is misspelled. Still underscores the misspelled word in red, but then it "offers no suggestions" always. Even for the most trivial misspellings. Yet, in other apps such as Notepad, spell check works fine, like always.)

Thanks for the clarification.

I suggest doing the following:

• Download the latest chipset driver from the link below and install it.

https://download.gigabyte.com/FileList/Driver/m...

(Extract the ZIP file, double-click the file "mb_driver_597_chipset_6.05.16.221" to run it, and follow the on-screen instructions to install the driver.)

• I noticed that the motherboard BIOS is outdated. I suggest you update it by following Gigabyte's instructions.

Then, see if there are any changes in Device Manager.

Also, see if you can install the Wi-Fi adapter driver.

I'll leave the Wi-Fi adapter driver in the link below just in case.

https://download.gigabyte.com/FileList/Driver/m...

(Extract the ZIP file, double-click the file "674_6001.16.119.0_SETUP" to run it, and follow the on-screen instructions to install the driver.)

If the problem persists, let me know. Click on the "Reply" button below my reply.
