If you need to fix WiFi issues on Windows 11, begin with the simplest checks. First, make sure Airplane Mode is off. Click the network icon in the taskbar and toggle Airplane Mode off. Also check your laptop’s hardware WiFi switch or function key (like Fn + F12) and turn the wireless adapter on.
Next, test the same network on another device. Use a phone, tablet, or second PC. If other devices connect fine, the problem is likely in Windows 11, not your router or ISP.
Use Windows 11 built‑in troubleshooters
Windows 11 includes two built‑in troubleshooters that can fix many WiFi issues automatically. Go to Settings → System → Troubleshoot → Other troubleshooters. Run both “Internet Connections” and “Network Adapter”. Windows scans for misconfigurations and often applies quick fixes.
These tools won’t solve every problem. They can clear temporary glitches and reset small network settings. In many cases, they save you from doing manual repairs.
Restart your router and modem
Many WiFi issues on Windows 11 actually come from the router or modem. Unplug your router and modem from power. Wait about 30–60 seconds. Plug the modem back in first, then the router, and let both fully reboot.
After the router comes back online, reconnect your Windows 11 device to the same WiFi network. Check if the “no internet” or weak‑signal messages disappear. A simple router reset often clears DHCP conflicts and other glitches that make Windows show “WiFi problem” icons.
Enable and reinstall the WiFi adapter
Sometimes the WiFi adapter gets disabled or corrupted. This breaks the connection even though networks still appear. Press Win + X, choose Device Manager, then expand Network adapters. Look for your wireless adapter (often called “Wi‑Fi”, “Wireless”, or with a chip name like “Intel” or “Realtek”).
Right‑click the adapter and choose Disable device. Wait a few seconds, then right‑click again and choose Enable device. If the problem persists, right‑click and choose Uninstall device. Restart your PC, and Windows will reinstall the driver automatically. This often fixes sudden WiFi drops or “no available networks” after an update.
Update or roll back the WiFi driver
An outdated or buggy WiFi driver often causes persistent WiFi issues on Windows 11. In Device Manager, right‑click your wireless adapter and choose Update driver → Search automatically for drivers. Windows downloads and installs the latest compatible version if available.
If the issue started after a recent Windows update, try rolling back the driver. Right‑click the adapter, open Properties → Driver → Roll Back Driver (if the option is active). You can also visit your laptop or motherboard manufacturer’s site and install the latest WiFi driver manually. This gives you a cleaner, more stable setup.
Reset network settings in Windows 11
When multiple WiFi problems stack up, reset the entire network stack. Go to Settings → Network & Internet → Advanced network settings → Network reset. Confirm Reset now. This removes all saved networks, VPNs, and custom adapters. Then Windows reinstalls network components.
After the reset, reconnect to your WiFi network and re‑enter the password. Most temporary software glitches, IP conflicts, and odd DNS behavior disappear. A network reset is a powerful one‑button fix for stubborn WiFi issues on Windows 11.
Fix IP and DNS problems with commands
Some WiFi issues come from broken IP configurations or DNS caching. Open Command Prompt as Administrator. Search for “cmd”, right‑click it, and choose Run as administrator. Then run these commands in order:
textipconfig /release
ipconfig /renew
netsh winsock reset
netsh int ip reset
Restart your PC afterward. These commands clear your IP lease, request a fresh address, and reset the Windows socket and TCP/IP stack. They often fix “connected, no internet” or unstable WiFi.
You can also flush DNS with ipconfig /flushdns. You can set your router or DNS to a public provider like Google (8.8.8.8) in Network settings → Properties → Internet Protocol Version 4 (TCP/IPv4). This helps if DNS timeouts cause slow or broken web access.
Tweak power management and services
Windows can turn off the WiFi adapter to save power. That can cause dropped connections or adapters that “disappear.” In Device Manager, right‑click your wireless adapter → Properties → Power Management. Then uncheck “Allow the computer to turn off this device to save power.”
Also check the WLAN AutoConfig service. Press Win + R, type services.msc, and find WLAN AutoConfig. Double‑click it, set Startup type to Automatic, and click Start if it is stopped. This service manages WiFi profiles and scanning. If it is disabled, Windows 11 may refuse to connect to or show WiFi networks correctly.
Disable proxy and VPN interference
If you use a VPN app or a manually configured proxy, those can block or reroute your WiFi connection in Windows 11. Go to Settings → Network & Internet → Proxy. Switch “Use a proxy server” to Off unless you specifically need it.
Temporarily quit or disable VPN software and see if WiFi starts working. Many “WiFi problem” or “limited connectivity” issues vanish when the VPN or proxy turns off. This reveals that the network itself was fine but the tunnel or proxy was misconfigured.
When to try system restore or clean install
If WiFi worked fine before a recent Windows update or driver change but suddenly broke, a system restore can help. Create a restore point under System Properties → System Protection → Create (if you haven’t already). Then use System Restore to roll back to before the WiFi issues started.
As a last resort, you can perform a clean Windows 11 install while keeping your files. This wipes misconfigured settings, broken drivers, and third‑party network software. You get a fresh network stack that usually resolves deep‑rooted WiFi issues on Windows 11.
By following these steps in order, you can fix WiFi issues on Windows 11 for most common problems. These include no internet, disappearing networks, driver glitches, and DNS‑related slowdowns.
