Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesTo manually fix Wi-Fi, first identify whether the failure is on one device, the wireless link, your router or modem, or your internet service. Check Wi-Fi and Airplane Mode, test another device on the same network, then work through reversible fixes before resetting anything.
Identify what is failing
“Wi-Fi is broken” can describe several different problems. Note which one you have before changing settings:
As an Amazon Associate I earn from qualifying purchases.
- The network does not appear: The router may not be broadcasting, the signal may be out of range, or the device may not support the network’s band.
- The device cannot join: Check the password and whether the saved network profile or router security settings have changed.
- The connection drops or is weak: Signal, distance, obstacles, interference, or router placement may be involved.
- Wi-Fi connects, but there is no internet: The device has joined the local wireless network, but that does not prove the router has a working connection to the internet. Microsoft describes this Windows state as being connected to the local network but not the internet (Microsoft’s Windows Wi-Fi troubleshooting guide).
Also note when the problem began: for example, after an operating-system update, waking the device from sleep, changing the router, or changing a VPN or security setting. On Windows, record the symptoms and when they occur before trying steps that reset settings or remove drivers; doing so can change the behavior you are trying to diagnose (Microsoft Learn’s network troubleshooting baseline guidance).
Check the device and compare connections
Start with the basics
- Make sure Wi-Fi is on and Airplane Mode is off.
- Move closer to the router and try again. A weak or missing signal can mean the device is out of range (Google’s Android connection guidance).
- If Wi-Fi is disabled or unavailable on an iPhone or iPad, check whether the Wi-Fi control is greyed out. Apple recommends restarting the device in that situation (Apple’s Wi-Fi troubleshooting guidance).
Test another device on the same Wi-Fi
Try the network on a second phone, tablet, or computer. If that device works, focus first on the original device’s Wi-Fi adapter, saved network profile, or settings. If several devices cannot get online, investigate the shared router, modem, or internet service instead. Apple also recommends checking other devices and contacting the ISP if none can connect to the internet (Apple’s Wi-Fi troubleshooting guidance).

If possible, connect the affected device to a different Wi-Fi network. A device that fails on unrelated networks while other devices work points toward its own software, adapter, driver, or hardware rather than your home router.
Try reversible fixes first
- Toggle Wi-Fi off and on. Wait a few seconds before turning it back on, then try the connection again.
- Reconnect to the network. If you suspect stale saved credentials or profile settings, forget the network and join it again. Make sure you know the correct password before removing the saved connection.
- Restart the affected device. This is a reasonable early step if toggling Wi-Fi does not help.
- Power-cycle the router. Unplug it, wait 30 seconds, reconnect power, and allow time for its lights and connection to return. Google gives this 30-second interval in its Android troubleshooting instructions; follow your router’s own instructions if they differ (Google’s Android connection guidance). A combined router/modem may have only one power connection. Other people using the network will be disconnected briefly.
A power cycle is not the same as a factory reset. Do not press a reset button as a substitute for unplugging the router: a factory reset can erase its setup and require reconfiguration.
Check range, frequency band, and compatibility
Try the device close to the router, then test another band if the router offers one and the device supports it. Some consumer routers broadcast separate 2.4 GHz and 5 GHz networks; a device may not support every band the router offers. Microsoft and Apple both recommend checking band or frequency compatibility when troubleshooting (Microsoft; Apple).

Neither band is always the better choice. Distance, walls and other obstacles, local interference, and device capability affect the connection. If the connection repeatedly drops, changing the router’s wireless channel may help, but the menu and available options depend on the router model.
If Wi-Fi connects but there is no internet
When a device is associated with Wi-Fi but offline, check whether it received a usable address and whether the failure is upstream of the wireless link. Router menus and labels vary by model, so use the manufacturer’s instructions for device-specific settings.
Windows: check the address and router connection
Microsoft recommends checking the assigned IP address, renewing the IP configuration, flushing DNS, and reviewing proxy settings. An address beginning with 169.254. can indicate that Windows did not obtain an address from the router; the router’s DHCP service or its connection to the device may need attention. Microsoft also describes checking the default gateway and pinging it: if the router responds but internet access still fails, the modem or ISP may be the problem (Microsoft’s Windows Wi-Fi troubleshooting guide).

Review proxy settings if the device is configured to route traffic through a proxy. On a managed school or work device, ask the administrator before changing organization-managed network settings.
Recommended Free Tools
Test the modem or service
Check that the physical WAN connection between the modem and router is secure. If you have an Ethernet cable and a computer with an Ethernet port, you can connect the computer directly to the modem to help distinguish a Wi-Fi-router problem from a modem or ISP problem. Follow your ISP’s instructions for connecting devices to the modem; some service setups require restarting the modem when changing the connected device. TP-Link also recommends checking modem and WAN connections and testing directly on the modem for its equipment (TP-Link’s no-internet troubleshooting guide).
If the direct modem test also fails after the modem has restarted, contact your ISP. Avoid advanced router changes such as MAC cloning, LAN IP changes, or manually assigning DNS as first-line fixes; they are configuration-specific and can make diagnosis harder.

Windows 10 and 11: run network commands carefully
If the basic checks fail, Microsoft lists these commands in this order for an elevated Command Prompt on Windows 10 and Windows 11. Open Start, search for Command Prompt, select Run as administrator, and run each command separately:
netsh winsock resetnetsh int ip resetipconfig /releaseipconfig /renewipconfig /flushdns
The first commands reset Windows networking components, the release and renew commands request an IP address again, and the final command clears the DNS resolver cache. Follow any restart prompt and retest the connection. These steps and their order come from Microsoft’s Windows troubleshooting instructions.
If the problem began after an update, check Windows Update and the device maker’s guidance for network-adapter drivers or firmware. Uninstalling a network adapter driver is a later step; Microsoft advises having a backup driver available. Windows network reset should be a last resort because it removes and reinstalls network adapters with default settings. Record relevant symptoms and timing before using disruptive steps (Microsoft Learn).

iPhone, iPad, and Android: leave network resets until later
iPhone and iPad
Apple’s network-settings reset removes saved Wi-Fi networks and passwords, mobile settings, and VPN/APN settings. Use it only after the other troubleshooting steps fail. If the device is managed by a school or business, consult its IT team before changing managed network settings (Apple’s Wi-Fi troubleshooting guidance).
Android
Android settings names and reset paths vary among manufacturers and device versions. Use your phone maker’s support instructions for the exact network-reset path rather than assuming every Android device has the same menu. A reset can remove saved network information, so try toggling Wi-Fi, reconnecting, and restarting first (Google’s Android connection guidance).
When to contact your ISP or device maker
- Contact your ISP if multiple devices are offline, service may be out, or a direct modem test does not work.
- Contact the router maker if a router-specific setting, firmware issue, or suspected hardware fault remains after basic checks.
- Investigate the affected device if it fails across unrelated Wi-Fi networks while other devices connect successfully; the operating system, adapter, driver, or hardware may need attention.
Router instructions from one manufacturer may not apply to another brand or model, so use the documentation for your equipment when checking firmware or changing configuration (TP-Link’s router-specific guide).
