Ultimate Windows WiFi Troubleshooting Guide

Wireless networking problems are particularly annoying because there are so many things that can cause them. Maybe you’re missing a driver or your computer’s power options aren’t properly set. Did you check the wireless switch (if you have one)? So many things can go wrong.

In this article, we’re going to troubleshoot Windows 10 WiFi by exploring the most common issues. Let’s get started.

Limited Connectivity

Many Windows 10 users get a limited connectivity message and it’s challenging to figure out what’s causing it. It can be triggered by outdated drivers, a faulty Ethernet cable, your network adapter, or even the antivirus software you use. The only thing you can do is troubleshoot WiFi one step at a time and hope for the best.

We’re going to try the most common solutions, but make sure to try other fixes mentioned in this article if those don’t work.

The first thing you should try is the built-in Windows 10 networking troubleshooter. In a lot of cases, WiFi problems can be solved automatically.

The easiest way to access this resource is to typetroubleshootin the search box and select theFind and fix network problemsoption.

This opens theInternet Connectionspanel.

Let Windows diagnose the networking issues and apply any suggested fixes. If this doesn’t help, you should also troubleshoot the network adapter. Typetroubleshoot network adapterin the search box and follow the same steps.

If the troubleshooter found an error that says WiFi doesn’t have a valid IP configuration, you should reset the TCP/IP. This is the most common solution to this problem, although outdated drivers can also cause it.

To reset the TCP, typecommand promptin the Windows search box. Before you launch the prompt, make sure to right-click and select theRun as administratoroption otherwise some commands might not work.

Next, type the following commands separately by pressing theEnterkey after each one:

netsh winsock reset

ipconfig /release

ipconfig /renew

netsh int ip reset

ipconfig /flushdns

Restart your computer and check if your wireless connection works now. If it doesn’t, continue to troubleshoot wifi using our tips below.

Having antivirus software is important, but it can sometimes cause a conflict that leads to a limited internet connection message. Take note that Windows Defender, the antivirus that comes with Windows 10, shouldn’t cause any problems with your wireless connection.

Most users report that third-party antivirus software can block WiFi. So if you’ve been struggling with trying to figure this out, try disabling your antivirus. If BitDefender, Avast, AVG, or a similar antivirus is indeed the culprit, uninstall it.

Missing WiFi Icon

In some cases, wireless is disabled. You can’t find the WiFi icon and if you dig deeper into your network settings you won’t find a wireless section.

A lot of users report this problem, especially after a clean Windows 10 install. This is usually due to missing or outdated WiFi drivers. The WiFi module might also be the culprit if you purchased one so make sure it’s properly connected.

That said, there are several solutions you can try.

Start looking at your drivers, especially if you just installed Windows 10. A lot of users install the operating system without connecting their machine to the Internet. As a result, Windows can’t install any drivers automatically during the installation process, so some of them will be missing.

1. Navigate to the Settings panel and selectUpdates & Security.

2. Next, you need to check for driver updates by clicking onView optional updates.

3. Click onDriver updatesto see if you have anything to download.

In your case, you should have other drivers than the ones seen in this image. Hopefully, one of them is the WiFi driver. Make sure you’re connected to the Internet through a network cable or your smartphone’s connection and download the drivers.

In some cases, the WiFi driver is corrupted, and updating it won’t do anything. What you need to do is reinstall it. To do that, you need first uninstall the driver and then either check for updates using the previous solution or download it from the manufacturer’s website.

To remove the existing driver, head over to theDevice Managerand look for your WiFi driver underNetwork adapters.

Select your wireless driver, double-click to launch the Properties panel, and navigate toDriver. There you’ll find theDriver Detailsbutton, which will tell you everything you need to know about the driver.

You need this information if you want to download and install the driver from the WiFi card manufacturer’s website.

Now, go back to the driver inside the device manager, right-click on it, and select theUninstall deviceoption. This will remove the driver from your computer so that you can properly install it.

Once the driver has been removed, you can either go back to theCheck for Updatespanel we talked about above or to the manufacturer’s website. Either way, install the driver and restart your computer.

WiFi Disconnected After Sleep Mode

Your wireless connection works just fine until your computer enters Sleep/Hibernate mode? Chances are you’re dealing with an annoying power-saving option that keeps your computer from returning your WiFi connection after it wakes up. To fix this, typePower Planin the Windows search bar and selectEdit Power Plan. This opens your computer’s current power plan settings. Then click on theChange advanced power settingsoption.

Scroll toWireless Adapter Settings, expand it, and change thePower Saving ModetoMaximum Performance.
