Wifi Not Working On Laptop

Last updated: August 06, 2026 · 5 min read

Why Is My Laptop Suddenly Not Getting Wi-Fi?

When your laptop suddenly stops connecting to wifi, it’s usually because something changed in your computer’s settings. This happens more often than you’d think.

The most common reasons are simple. Windows might have turned on airplane mode during an update. Your wifi adapter could have been accidentally disabled. Or your network driver needs a quick refresh.

Here’s what causes most wifi problems:

• Airplane mode got switched on: Windows 10 and Windows 11 sometimes turn this on after updates
• Network driver issues: The small program that runs your wifi card needs updating
• Windows settings changed: Your wifi adapter might be turned off in settings
• Power saving features: Windows sometimes turns off your wifi to save battery

Don’t worry — you haven’t broken anything. These are all easy fixes that we’ll walk through step by step.

Why Is Wi-Fi Not Working on My Laptop But Working on Other Devices?

This is one of the most frustrating situations. Your phone connects to your Xfinity or Comcast wifi just fine. Your tablet works. But your laptop refuses to connect.

When wifi not working on laptop happens but other devices work fine, the problem is definitely in your laptop. Not your router. Not your internet service. Your laptop.

Here’s how to fix it:

1. Check airplane mode first: Look in your system tray (bottom right corner). If you see an airplane icon, click it and turn airplane mode off. This fixes the problem about 40% of the time.
2. Restart your laptop: I know this sounds too simple, but it works. Click Start, click Power, and click Restart. Wait for it to fully restart.
3. Check if wifi is enabled: Click the Start button, type “Device Manager,” and press Enter. Look for “Network adapters” and click the arrow next to it. Find the one that says “Wireless” or “Wi-Fi” in the name. If you see a down arrow on it, right-click and choose “Enable.”
4. Forget and reconnect to your network: Click the wifi icon in your system tray. Find your network name. Right-click it and choose “Forget.” Then click your network again and enter your password fresh.

According to Microsoft’s official guidance, restarting your network adapter solves most connection problems within minutes.

Why Is My Laptop Not Connecting to Wi-Fi But My Phone Is?

This is the same problem as above, just worded differently. And yes, it’s incredibly common.

Your phone uses different wifi hardware than your laptop. So when your phone connects but your laptop doesn’t, it means your laptop’s wifi adapter has a problem.

The fix is to update your network driver. Here’s how:

1. Open Device Manager: Click Start, type “Device Manager,” and press Enter. Don’t worry — you’re just looking, not breaking anything.
2. Find your wifi adapter: Look for “Network adapters” and click the small arrow next to it. You’ll see a list. Find the one that mentions “Wireless,” “Wi-Fi,” or “802.11.”
3. Update the driver: Right-click on your wifi adapter. Choose “Update driver.” Then click “Search automatically for drivers.” Windows will look for the newest version and install it.
4. Restart after updating: Once the update finishes, restart your laptop. This helps the new driver work properly.

Many people using wifi not working on laptop reddit forums report this fixes their Dell or HP laptops immediately.

If Windows says your driver is up to date but you’re still having problems, you might need professional help. We’ll talk about when to call for help in a moment.

What About Windows 11 Wifi Option Not Showing?

Sometimes the wifi icon disappears completely from your system tray. Or when you click the network icon, you don’t see any wifi networks at all.

This happens on both wifi not working on laptop windows 10 and Windows 11 systems. It usually means your wifi adapter got disabled or Windows can’t find it.

Here’s the fix:

1. Check if your adapter is disabled: Open Device Manager (type it in the Start menu). Look under “Network adapters.” If your wifi adapter has a down arrow, right-click it and choose “Enable device.”
2. Run the network troubleshooter: Click Start, then Settings (the gear icon). Click “Network & Internet.” Scroll down and click “Network troubleshooter.” Windows will scan for problems and try to fix them automatically.
3. Check for a physical wifi switch: Some Dell and HP laptops have a physical switch or function key to turn wifi on and off. Look for a key with a wifi symbol (usually F2, F3, or F12). Try pressing Fn + that key.

According to AARP’s 2025 Tech Trends research, 1 in 5 adults 50+ say getting setup and tech support is a barrier to using technology. You’re not alone in finding this confusing.

Special Steps for Common Router Brands

Sometimes your laptop can’t connect because your router needs attention. Whether you have AT&T, Spectrum, Xfinity, or use a Netgear or Linksys router, these steps work the same way.

Try this simple router restart:

1. Unplug your router: Pull the power cord out of the back of your router. Not the cable that goes to the wall jack — the power cord.
2. Wait 30 full seconds: Count to 30. This clears the router’s memory.
3. Plug it back in: Put the power cord back in. Wait 2 minutes for all the lights to come back on.
4. Try connecting again: Look for your wifi network on your laptop and try to connect.

This works whether you have Comcast, AT&T fiber, or Spectrum cable internet.

My Laptop Cannot Detect Wifi But My Phone Can — What Now?

If your laptop can’t even see any wifi networks at all, but your phone sees them fine, your laptop’s wifi hardware might be turned off completely.

First, check Device Manager one more time. Make sure your wifi adapter doesn’t have a yellow triangle next to it. That triangle means there’s a driver problem.

If you see the yellow triangle, you’ll need to reinstall the driver. This sounds scary but it’s not:

1. Right-click the wifi adapter in Device Manager: Choose “Uninstall device.” A warning will pop up — click “Uninstall” again.
2. Restart your laptop: Windows will automatically reinstall the driver when it starts back up.
3. Check for wifi networks again: After your laptop fully restarts, click the network icon and look for available networks.

You’ve got this. Most people fix this problem in under 10 minutes.

When Should You Ask for Help Instead of Fixing It Yourself?

Sometimes the problem is more technical than these simple fixes can handle. Here’s when it makes sense to call for help:

• You’ve tried everything above and wifi still doesn’t work: If you’ve restarted, updated drivers, and checked all settings but nothing helps, there might be a deeper Windows problem.
• Your wifi adapter doesn’t appear in Device Manager at all: This could mean hardware failure or a serious driver issue that needs expert diagnosis.
• You’re not comfortable opening Device Manager: That’s completely okay. Some people prefer having an expert handle it. There’s no shame in asking for help.
• Error messages pop up that you don’t understand: If Windows shows technical error codes or warnings, it’s better to have someone who understands them take a look.
