How to Fix a Laptop That Can’t Detect Wi-Fi Networks

To fix a laptop that can’t detect Wi-Fi networks, turn on wireless, disable Airplane mode on Windows, move closer to the router, and refresh the network list. If networks remain missing, check the wireless adapter, run network troubleshooting, and update its driver. The Windows steps use Windows 11 menus; separate steps cover Mac, Chromebook, and Ubuntu laptops.

Turn on wireless and refresh the network list

Move your laptop close to the router, wait about a minute, then reopen the network list. If your laptop has a physical wireless switch, move it to its on position. On a Dell laptop, disconnect Ethernet before checking the wireless controls.

On Windows 11, click the taskbar network icon, turn off Airplane mode, and turn on Wi-Fi. If Wi-Fi is already enabled, turn it off and back on. You can also open Start > Settings > Network & Internet, turn on Wi-Fi, and open it to view networks.

To refresh the list on current Windows 11 builds, select the taskbar Network, Sound, or Battery icons, then select Manage Wi-Fi connections. Select Refresh network list in the lower-right corner.

Check the router when one network is missing

If other networks appear but yours does not, check the router’s wireless visibility and the frequency your adapter permits. Restart your router and use its exact model’s instructions to install manufacturer-recommended firmware. These router checks require access as the router’s owner.

On supported TP-Link routers, connect through Ethernet or another working device and sign in at the router’s settings portal. Open Advanced > Wireless > Wireless Settings. For the required band, check Enable, or check Enable Wireless Radio when that is the label, uncheck Hide SSID, and select Save. On TP-Link Wi-Fi 8 routers, basic wireless settings such as the SSID are under Wi-Fi > Main Network instead.

On Windows 11 adapters that expose band controls, open Device Manager > Network adapters, open your adapter’s Properties, and select Advanced. Set Wireless Mode or Band to permit the router’s frequency. If your adapter does not expose those properties, continue with the driver checks.

Enable the Windows wireless adapter

On Windows 11, open Settings > Network & Internet > Advanced network settings, then select Enable beside Wi-Fi if the adapter is disabled. Another route is Device Manager > Network adapters, where you can right-click the wireless adapter and select Enable device.

For an adapter that exposes power controls, open its Properties > Power Management. Uncheck Allow the computer to turn off this device to save power, then check the network list again. If that tab is missing, continue with the network troubleshooter.

Run Windows troubleshooting and restart its wireless service

On current Windows 11, open Start > Settings > System > Troubleshoot > Other troubleshooters. Select Network and Internet to open Get Help and follow its troubleshooting prompts.

If networks remain missing, restart WLAN AutoConfig. Press Win + R, enter the following command, and press Enter.

services.msc

Right-click WLAN AutoConfig and select Restart. Reopen the available-network list to check whether scanning has resumed.

Update or reinstall the wireless driver

Right-click Start, open Device Manager, and expand Network adapters. Right-click your wireless adapter, select Update driver, then choose Search automatically for updated driver software.

If you need to install a driver manually, download and extract the manufacturer’s package that matches your laptop model, Windows version, and processor architecture. Dell owners can identify their laptop by model or Service Tag on Dell Drivers & Downloads. HP owners can identify their laptop and select its operating system on HP Software and Driver Downloads.

Back in Device Manager > Network adapters, right-click the adapter and select Update driver, then select Browse my computer for drivers. Select Browse..., choose the extracted folder, select OK, and select Next. For affected Intel adapters that cannot see newer TP-Link Wi-Fi 6, 6E, or 7 networks, install the latest driver supported by your adapter.

Uninstalling removes the adapter from Windows, so save your work and keep a manufacturer driver available offline first. Right-click the adapter in Device Manager > Network adapters, select Uninstall device, then select Uninstall. Restart your computer so Windows can attempt driver reinstallation. If Windows does not restore it, use the saved manufacturer driver.

Restore wireless scanning on a Mac

On macOS 27, open System Settings > Wi-Fi and turn on Wi-Fi, or switch it off and back on. Open Control Center, point to Wi-Fi, and click its arrow, then expand Other Networks. This shows networks outside the known-network list.

If the Wi-Fi network service is missing and the wireless hardware is recognized, open the Apple menu > System Settings > Network. Open the Action pop-up menu, select Add Service, set Interface to Wi-Fi, and enter a Service Name. Click Create, then check Wi-Fi again.

For a deliberately hidden network, open the menu-bar Wi-Fi menu > Other Networks > Other. Enter the exact network name, choose Security, provide the required credentials, and click Join. On macOS 27, when the missing network uses legacy options, open the Apple menu > System Settings > Wi-Fi > Advanced and enable Show legacy networks and options.

If scanning still fails on macOS 27, hold Option while clicking the Wi-Fi menu, then select Open Wireless Diagnostics. Follow the analysis and inspect the Summary; this tool does not change network settings. Restart the Mac, and if another network works, use it to install the macOS updates offered for your Mac before retrying the original network.

Check Chromebook wireless controls and diagnostics

On a Chromebook, select the time, select Not Connected, and turn on Wi-Fi. Alternatively, open Settings > Network > Wi-Fi and enable it. The Chromebook scans automatically.

To join a hidden network, open Settings > Network > Add connection > Add Wi-Fi, enter its details, and select Connect. For subsequent discovery, open Wi-Fi > Known networks, select the network, turn on Hidden network, and select Save.

If Wi-Fi still fails, restart the Chromebook, then select the time and open Settings > About ChromeOS > Diagnostics. Inspect Connectivity, and select Save test details to preserve the results for the manufacturer. A working Ethernet cable or USB Ethernet adapter connected to the router can provide temporary connectivity.

For a Chromebook still receiving updates, use that working connection to select the time and open Settings > About ChromeOS > Check for updates. Restart when the downloaded update requests it. On a managed Chromebook, ask your administrator for help if you cannot update it. Contact the manufacturer if wireless troubleshooting still fails.

Rescan wireless networks on Ubuntu

On Ubuntu Desktop using GNOME, open the top-right system menu and select Wi-Fi. Scroll through the networks, select the desired name, enter its password, and click Connect.

If your network is hidden, open the system menu, select the Wi-Fi arrow, then select All Networks. Open the window’s top-right menu and select Connect to Hidden Network…. Choose New under Connection, enter the network name and Wi-Fi security details, then click Connect.

On Linux distributions using NetworkManager and nmcli, you can enable wireless and request a fresh scan from Terminal. Run these commands separately, in order; they cannot override a physical radio block.

nmcli radio wifi on

nmcli device wifi rescan

nmcli device wifi list

Reset Windows networking or check the hardware

Keep Windows network reset as a last resort after the adapter, troubleshooter, and driver checks. Resetting Windows networking may require you to reconfigure VPN software. On Windows 11, open Settings > Network & internet > Advanced network settings > Network reset, select Reset now, select Yes, and wait for the restart.

On Dell laptops with these BIOS controls, you can enable wireless in firmware. Restart, press F2 at the Dell logo, open Connection settings, check WLAN, and save changes and exit. BIOS paths vary by model, so use your model’s instructions when these controls differ.

On Dell laptops with these preboot diagnostic options, restart and press F12 at the Dell logo, then select Diagnostics. Select ADVANCED TEST, uncheck Select all, select NETWORK, select Through mode, and select RUN TEST. Report failures to Dell, since a failed wireless adapter can require replacement.

Frequently Asked Questions

Why can’t my laptop see a 6 GHz network?

For Intel Wi-Fi 6E or Wi-Fi 7 systems, both your laptop and router must support Wi-Fi 6E or Wi-Fi 7; Wi-Fi 6 alone does not provide 6 GHz compatibility. Update Windows 11 and the Intel driver, and confirm manufacturer and regional enablement. Wi-Fi 7 functionality additionally requires Windows 11 24H2 or later.

What should I do if my HP wireless key does not work?

For supported HP Windows notebooks, identify your laptop on HP’s driver site and open Driver-Keyboard, Mouse and Input Devices. Install HP Wireless Button Driver or HP Hotkey Support, whichever HP supplies for your model.

How do I restore a missing Wi-Fi icon on my Mac?

On macOS 27, open System Settings > Menu Bar and select Wi-Fi. This restores the menu shortcut; it does not repair failed wireless hardware.

Can a Chromebook hardware reset help after other fixes fail?

A hardware reset is a later troubleshooting option for most Chromebooks, though Google lists model-specific exceptions. It can delete some files in Downloads, so back up Downloads first. Turn the Chromebook off, hold Refresh, tap Power, and release Refresh when startup begins; use your model’s instructions if it requires a different procedure.
