Network Adapter Not Working

Last updated: August 07, 2026 · 5 min read

What Causes a Wireless Adapter to Stop Working?

Your wireless adapter can stop working for several reasons, and most of them aren’t your fault. The most common cause is a software glitch that happens after a Windows update. Sometimes Windows 10 or Windows 11 updates can accidentally mess up your network settings.

Driver problems are another big reason. Think of drivers like translators that help your computer talk to your WiFi adapter. When these translators get outdated or corrupted, your computer can’t communicate properly with your network.

Physical problems happen too. If you have a laptop, there might be a physical WiFi switch on the side or a keyboard combination that turns WiFi on and off. According to AARP, 91% of adults 50+ now own a smartphone, yet many still struggle with everyday tech problems like these simple switches.

Power management settings can also turn off your adapter to save battery. Your computer might be trying to help, but it ends up blocking your internet connection instead. This is especially common with laptops running on battery power.

How Do I Tell if My Network Adapter Is Bad?

Before you panic, let’s figure out if your adapter is actually broken or just having a temporary problem. Here’s how to check.

First, look at your system tray at the bottom right of your screen. Do you see any network icon at all? If you see a red X or a yellow triangle with an exclamation mark, that’s actually good news. It means Windows can see your adapter—it just can’t connect.

Next, open Device Manager. Press the Windows key and type “device manager” then press Enter. Look for “Network adapters” and click the arrow next to it. Do you see your WiFi adapter listed? If it has a yellow triangle or down arrow next to it, the adapter exists but isn’t working right.

If your adapter appears and disappears, or if your computer completely freezes when you try to connect to WiFi, that might mean hardware failure. But honestly, that’s rare. Most of the time, the network adapter not working on Windows 11 or Windows 10 is just a software issue.

Try connecting to the internet with an ethernet cable plugged directly into your router. If that works fine, your network adapter for WiFi is the problem—not your internet service from Xfinity, AT&T, or Spectrum.

How Do I Reset My Network Adapter?

Resetting your network adapter is easier than it sounds. Windows has a built-in tool that does most of the work for you. Here’s exactly what to do.

1. Open Windows Settings: Click the Start button and click the gear icon. Or press the Windows key + I on your keyboard. Don’t worry if it takes a few seconds to open.
2. Go to Network Settings: Click on “Network & Internet” in the left sidebar. You’ll see several options appear on the right side of the screen.
3. Find Advanced Settings: Scroll down and click “Advanced network settings.” This is where Windows keeps the tools for fixing connection problems.
4. Reset Your Network: Click “Network reset” at the bottom. Windows will warn you that this removes all your network adapters and sets everything back to default. Click “Reset now” and then restart your computer.
5. Reconnect to Your WiFi: After your computer restarts, click the WiFi icon in your system tray. Find your network name (it might be labeled with your Comcast or Netgear router name) and type in your password again.

This process fixes most wifi adapter not working Windows 11 problems in one go. It takes about 5 minutes total, including the restart time.

If the network reset doesn’t work, you can also try the Windows troubleshooter. Right-click the network icon in your system tray and select “Troubleshoot problems.” Windows will scan for issues and try to fix them automatically. According to Microsoft’s official guidance, this troubleshooter solves about 70% of common network problems.

Do Network Adapters Go Bad?

Yes, network adapters can eventually fail, but it doesn’t happen often. Most adapters last 5 to 10 years or more. If your laptop or desktop is relatively new, hardware failure is unlikely.

Built-in WiFi adapters (the ones inside your laptop) rarely break unless the computer suffers physical damage. External USB WiFi adapters from brands like Netgear or Linksys can wear out faster because they get plugged and unplugged more often.

Here are signs your adapter might actually be failing: your WiFi connection drops every few minutes even when you’re sitting right next to your router, Device Manager shows “Code 10” or other error codes that won’t go away, or your computer completely freezes when you turn WiFi on.

The network adapter not working code 10 error specifically means Windows detected the device but couldn’t start it. This can be either a driver problem or actual hardware failure. Try updating your drivers first before assuming the worst.

If you’re dealing with an older computer running Windows 7, your network adapter might simply be too old to work properly with modern routers. Newer routers use different security protocols that older adapters don’t understand.

The good news? Even if your adapter is broken, replacing it isn’t expensive or complicated. USB WiFi adapters cost $15 to $40 and plug right into your computer. No tools required. If you’re not comfortable doing this yourself, our wifi & internet help service can walk you through the replacement or handle it remotely.

What About Driver Updates?

Drivers are small programs that help your network adapter talk to Windows. When they get outdated or corrupted, you’ll see your wifi network adapter not working on your laptop.

Windows usually updates drivers automatically, but sometimes it misses them. Here’s how to update manually:

1. Open Device Manager: Press Windows key + X and select Device Manager from the menu that appears.
2. Find Your Network Adapter: Click the arrow next to “Network adapters.” You’ll see a list of adapters. Look for one with “Wireless,” “WiFi,” or “802.11” in the name.
3. Update the Driver: Right-click on your WiFi adapter and choose “Update driver.” Select “Search automatically for drivers.” Windows will look online for the newest version.
4. Restart Your Computer: Even if Windows says no update was needed, restart anyway. Sometimes the change doesn’t take effect until you restart.

If automatic updates don’t work, you might need to uninstall the driver completely. Right-click your adapter in Device Manager and choose “Uninstall device.” Check the box that says “Delete the driver software for this device” if you see it. Then restart your computer. Windows will automatically reinstall a fresh copy of the driver when it starts up again.

This approach often fixes the network adapter not working reddit users report most frequently. It forces Windows to start over with a clean installation.

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

Sometimes the smartest thing you can do is call someone who fixes these problems every day. Here’s when that makes sense:

• You’ve tried restarting, resetting, and updating drivers, but nothing works
• You see error messages you don’t understand and feel nervous about clicking the wrong thing
• Your computer is showing multiple problems at once—not just WiFi issues
• You need your internet working right now for something important and don’t have time to experiment

Don’t feel embarrassed about asking for help. These problems can be tricky even for people who work with computers daily. According to AARP’s research on technology use, getting reliable tech support is one of the biggest challenges adults face when using computers.
