Check for Physical Connectivity Issues
Sometimes internet connection may fail due to simple things like a loose or unplugged network cable, modem, or router. If you're on a wireless network, your computer's wireless network interface card might be turned off.
Why is a WiFi network not showing up? Wi-Fi not showing up can be a technical glitch or an issue with the router. Besides this, using outdated drivers can prevent some Wi-Fi networks from showing up. Updating drivers or turning Wi-Fi networks off and on are probable solutions to this problem.
Network adapter turned off/disabled: The Wi-Fi connection problem isn't always caused by the router; your device could be the culprit. If a restart doesn't help, your network adapter could be disabled, or its drivers may need updating. Virus: If your device has a virus, it could block your ability to connect to Wi-Fi.
Your wired connection isn't plugged in properly. Your device is out of Wi-Fi range. Wi-Fi interference, problems with your internet provider. Outdated or missing network adapter drivers.
The error “Windows could not find a driver for your network adapter” only occurs when the driver installed for the adapter is either outdated, corrupted, or it is unavailable to use. Press Windows + R on your keyboard to bring up the Run box. Type – devmgmt. msc and press Enter to open the Device Manager.
Reboot your PC. Reboot your modem and router. Disable any VPN connections. Run the Windows network troubleshooter.
Resetting network settings, in simple words, resets your phone's network settings such as Wi-Fi, Bluetooth, VPN, and cellular connections to default values. That is, a network settings reset brings back all the network-related settings to their original state.
A no data connection error can be the result of a basic software glitch, damaged hardware, or even a system-wide outage that renders the entire mobile network unavailable.
Performing a network settings reset on a Windows 10 PC can fix several internet problems. Resetting network preferences can also solve Wi-Fi problems on an iPad and get the internet working again on Android tablets and smartphones.
Unplug the router and modem's power cords from the power outlet for 15 seconds. Plug the power cords back in. Check that all cords and cables are secure at both ends. Wait a few minutes, until the lights on the modem and router are working right.
Restarting your modem and router should be the first thing you do when encountering an internet signal issue. Don't skip this step! This is almost always what tech support will ask you to try first, as it often solves the problem. To restart your equipment, unplug the power cable for 60 seconds and plug it back in.
Restart your Windows 10 computer. Restarting a device can often fix most tech issues including those that prevent you from connecting to a Wi-Fi network. Check for Windows updates. These updates can fix problems in addition to downloading the latest versions of software and drivers needed to run everything efficiently.
It is possible that your PC's WiFi adapter can only detect the older WiFi standards (802.11b and 802.11g) but not the new ones (802.11n and 802.11ac). The other WiFi signals that it detects are probably using the older (b/g) ones. Check your router, or rather log into it, to find out what kind of signal it transmits.
Your issues with your wi-fi not working could be caused by you simply not being in the optimal range for your router. Most routers aren't designed to transmit signals through a large area, so you could be running into an issue with “digital dead zones” in your home or office.
