Wifi Link Speed capped only at 86.7 Mbps!

[rezwanaubhi]

I am supposed to get 400+ Mbps on my wifi! However, the link speed is only 86.7 Mbps. I have tried all the fixes but that produced no results at all. For this, I get only half speed in real that is around 40 Mbps where using LAN I even get 200Mbps+.

Is there any working solutions? I have Probook 440 G4 running on Windown 10. Thanks.

Thanks. But the thing is no matter how hard I try, the latest driver doesn't get installed! I even uninstalled the device and tried reinstalling but it doesn't get that version! What to do now?

No matter whatever I do, it doesn’t work! I think without having a fresh OS installation, it won’t get fixed! Thanks anyway.

Hello @rezwanaubhi 

! Save all your private data to an external usb3 connected harddisk and then reinstall your system !

Good luck

Hi, @rezwanaubhi 

According to the release notes from Intel, the latest driver should install version 19.51.40.1

ReleaseNotes_WiFi_22.140.0.pdf (intel.com)

Download the W10 Wi-Fi zip file from Intel.

Intel® PROSet/Wireless Software and Drivers for IT Admins

Unzip the file to its folder.

Go to the device manager, click on your PC's Intel 3168 AC wifi adapter.

Click on the driver tab.

Click on Update driver.

Select the 'Browse my computer for drivers' option and browse to the driver folder you unzipped.

Make sure the Include subfolders box is checked and the driver should update.

The Intel 3168 AC Wifi adapter has a maximum throughput of 433 MBPS o the 5.0 GHz Wi-Fi band with an excellent signal.

After you update the driver, what I suggest you do is to check to see what the actual connection speed of your Wi-Fi adapter is, not how fast the download speed is.

To do that, go to the Windows control panel>network and internet>Network and sharing center>under the view your active networks section, click on your wireless network connection listed there and it will show you what speed your Wi-Fi adapter is connecting at.

Here's my screenshot...you can see that my connection speed was currently at 721 MBPS on my Intel AX200 wifi adapter.

So even that is way below what the maximum throughput of that card is.
