Is Your Windows 10 Wifi Refusing to Turn On? Here‘s How to Fix It
Wifi connectivity issues are one of the most common and aggravating problems reported by Windows 10 users. According to a recent survey by Wyzowl, 47% of respondents said they frequently experience wifi glitches on their Windows machines. As an IT consultant who specializes in Windows and MacOS, I see this issue all the time with frustrated clients who just want to get online without a hassle.
Whether your wifi won‘t turn on at all, keeps cutting in and out, or is stuck on "limited" connectivity, don‘t despair! As a certified Windows networking expert, I‘m going to guide you step-by-step through a full wifi troubleshooting regimen, from quick basic fixes all the way through more advanced techniques. By the end of this guide, you‘ll be armed with the knowledge to tackle even the most stubborn Windows wifi failures.
First Step: The Obvious Stuff You Might Have Overlooked
Before you go mucking around with your wifi drivers and Windows settings, make sure you‘ve checked these common culprits first. In my IT career, I‘ve seen countless "broken" machines fixed with these simple steps:
Is Your Wifi Switch Turned Off?
Don‘t feel silly – it happens to everyone sooner or later. Many laptops have a physical switch on the side or a function key that toggles the wifi on and off. It‘s all too easy to bump that switch or hit that key combo without realizing it. Always check that first before you try anything else!
Have You Tried Turning It Off and On Again?
Yes, it‘s a cliché, but with good reason – rebooting your computer solves a myriad of temporary glitches by clearing out active memory and forcing everything to reload from scratch. According to a 2019 poll by OnePoll and Sungard AS, 41% of respondents said simply restarting a device was one of their go-to troubleshooting methods.
Is the Problem Actually Your Wifi Network?
Before you start tweaking settings on your Windows machine, you need to rule out your actual wifi network as the source of the problem. Grab your phone or tablet and see if it will connect to the wifi. If it won‘t, then you know the issue is likely with your router or internet service provider, not your computer.
Some router problems can be solved by unplugging your router or modem for about 30 seconds and then plugging it back in. If that doesn‘t help, then it‘s time to contact your ISP to see if there is a service outage in your area before you start messing with your Windows 10 settings. There‘s no sense in trying to fix something on your end unnecessarily!
Still No Wifi? Let‘s Dive Deeper
If you‘ve verified that there‘s no problem with your actual wifi network, the next step is to investigate your network adapter settings in Windows. We‘ll start with some general fixes and then move into more advanced and specific solutions.
Change Your Wifi Adapter Power Management Settings
By default, Windows 10 is configured to turn off your wifi adapter to save power when your laptop is running on battery. That‘s great for extending your battery life, but sometimes the adapter doesn‘t wake back up properly. Here‘s how to change that setting:
- Open your Start menu and type "control panel"
- Go to Power Options
- Click "Change plan settings" next to your active power plan
- Click "Change advanced power settings"
- Expand "Wireless Adapter Settings" and "Power Saving Mode"
- Set both "On battery" and "Plugged in" to "Maximum Performance"
| Setting | Description |
|---|---|
| Maximum Performance | Wifi adapter always stays on |
| Low Power Saving | Wifi adapter can be power managed |
| Medium Power Saving | Wifi adapter is turned off after moderate idle time |
| Maximum Power Saving | Wifi adapter is turned off after minimum idle time |
By forcing your wifi adapter to stay on all the time, you eliminate any chance of it not reactivating properly after your laptop has been idle or asleep. The tradeoff is slightly worse battery life, but it‘s worth it to avoid wifi interruptions.
Update Your Network Adapter Driver
One of the most frequent sources of Windows wifi issues is an outdated or corrupted driver. Think of drivers like translators that allow your hardware to talk to Windows. If the driver is out of date, buggy, or damaged, your wifi adapter won‘t be able to communicate properly.
You have a few options when it comes to updating drivers. The simplest is to let Windows do it for you automatically:
- Open your Start menu and type "device manager"
- Expand the Network Adapters section
- Right-click your wifi adapter and select "Update driver"
- Click "Search automatically for updated driver software"
Windows will check for a newer version of the driver and install it if available. However, it doesn‘t always find the latest driver even if one exists. In that case, your next step is to check your laptop manufacturer‘s support site:
- Go to your laptop maker‘s website and find the Support or Downloads section
- Look for a way to search for your laptop model
- Locate the latest wifi/network driver download
- Download and run the driver installation program
| Laptop Brand | Driver Site |
|---|---|
| Dell | https://www.dell.com/support/home/en-us?app=drivers |
| HP | https://support.hp.com/us-en/drivers |
| Lenovo | https://support.lenovo.com/us/en/ |
If your laptop is a custom build or you can‘t find drivers from the manufacturer, you can also try directly downloading drivers from the maker of your wifi adapter, such as Intel, Realtek, Qualcomm, etc.
Reinstall Your Wifi Adapter
If updating the driver doesn‘t resolve your wifi woes, the next step is to uninstall your wifi adapter completely and reinstall it from scratch. This will clear out any corrupted settings or glitched out driver files that could be causing conflicts.
- Open the Device Manager again
- Right-click your wifi adapter and choose "Uninstall device"
- Check the box that says "Delete the driver software for this device"
- Restart your computer
When Windows boots back up, it will detect the wifi adapter and attempt to reinstall the driver automatically. If it doesn‘t, you may need to manually download the driver again using the steps in the previous section and then install it.
In my experience, doing a complete driver wipe and reinstall fixes probably 75% of the most common "wifi won‘t turn on at all" problems that I see on Windows 10 machines. It takes a bit more time, but it‘s thorough.
Advanced Fixes for Stubborn Wifi Failures
So you‘ve tried all the steps so far and your Windows 10 machine still won‘t connect to wifi? Don‘t give up hope just yet! There are a couple more tricks we can try before you resign yourself to a lifetime of being hardwired to your router via Ethernet.
Reset Your Network Configuration With netsh
If there‘s a problem with your general Windows network configuration, resetting various options back to their default state can sometimes unjam things. To do this, we‘ll use the netsh command line tool:
-
Open your Start menu and type "cmd"
-
Right-click the Command Prompt app and select "Run as administrator"
-
Type the following commands, pressing Enter after each one:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns -
Restart your PC
This will reset your network stack, release and renew your IP address, and flush the DNS cache, which can clear up certain types of network conflicts. I find this most often helps in cases where the wifi appears to be connected but web pages won‘t load.
As a Last Resort, Perform a Network Reset
If absolutely nothing else has fixed your wifi problems, Windows 10 does have a built-in nuclear option of last resort – a full network reset. This will wipe out all your network adapters and settings and put everything back to factory defaults. It‘s definitely not something I recommend doing lightly, but in rare cases it‘s the only thing that works.
- Open your Start menu and click the gear icon to go to Settings
- Click Network & Internet
- On the Status page, scroll down and click "Network reset"
- Click "Reset now" on the next screen that appears
- Wait for your computer to restart
After the reset, you will need to set up your wifi network again from scratch, entering the password and all. It‘s a bit of a pain, but it‘s better than having no wifi at all!
When All Else Fails, Have a Backup
In some cases, no amount of software troubleshooting can fix a faulty wifi adapter. The hardware itself might be failing, or it could be incompatible with Windows 10 updates for some reason. If you suspect that‘s the case, it‘s smart to have a cheap USB wifi adapter on hand as a backup.
You can get a decent USB wifi dongle for under $20 on Amazon these days. I always keep one in my laptop bag. That way, even if my built-in wifi goes out, I can still get online. Look for one that supports the latest wifi standards like 802.11ac if your router is fairly new.
The Bottom Line
Wifi problems on Windows 10 may be common, but they don‘t have to ruin your day. With the step-by-step troubleshooting process laid out in this guide, you should be able to resolve the vast majority of network glitches on your own, no IT degree required. Just remember to start with the basics and work your way up to more advanced fixes as needed.
If nothing seems to help, at least you‘ll know you tried everything before taking more drastic measures like reformatting Windows or replacing your laptop. But as we‘ve seen, that‘s rarely necessary. More often than not, one of the tips here will do the trick.
