Step One: Confirm Whether Your Internet Provider Is Down
If all your devices get no internet connection, yet your WiFi indicator is still on, the most obvious answer is that your internet provider has an outage. Before you start rebooting and shuffling wires around, it's always a good idea to check this first.
Restart your device.
Open your Settings app and tap Network & internet or Connections. Depending on your device, these options may be different. Turn Wi-Fi off and mobile data on, and check if there's a difference. If not, turn mobile data off and Wi-Fi on and check again.
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.
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.
Whatever style of modem/router you have, you can do a manual reboot by unplugging the power cable (typically black) from the power port on the back of the router.
It's generally a good rule of thumb to reboot the main router and modem every couple of months. As mentioned previously, a router reboot can fix your connectivity issues— from having no connectivity at all to getting bogged down by a slow connection.
Routers, like computers, work best with regular hard resets. Resetting a router can also clear the memory, which is critical for those with multiple devices or an older router. Resetting your router is an easy way to prevent malware attempts – the FBI even recommends router resets for that reason.
Reset your network settings
If you're using iOS or iPadOS 14 or earlier, tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.
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.
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.
Wait 2-3 minutes for the modem to fully power off. All the lights on the modem should be off. Reconnect the power and Ethernet cables to the modem. Wait for the Internet light to turn solid, then check if the internet is working properly.
Reset Your Modem and Router (Power Cycle)
Leave the devices unplugged for 30 seconds, then plug the modem back in followed by the router. Give them both time to boot up and connect by watching the activity lights (usually 1 to 5 minutes). Then try connecting to the Internet again on your computer or connected device.
Check to make sure that your phone is connected to the correct network, and that the network's settings are correct. You may also want to try forgetting the network and reconnecting to it, as well as checking for any updates to your phone's firmware.
No data or media are deleted. Reset Network Settings: All network settings are removed. In addition, the device name assigned in Settings > General > About is reset to “iPhone,” and manually trusted certificates (such as for websites) are changed to untrusted. Cellular data roaming may also be turned off.
Reset your Network Settings
Go to Settings > General > Transfer or Reset [Device] > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.
Ideally, you should reboot them at least once a month to clear out the memory and refresh your connections. But don't confuse the term “reboot” with “reset”—they're not the same. A “reboot” simply restarts your wireless router, while a “reset” restores your router to its default factory settings.
Resetting your router will completely wipe any configurations you've saved and restore your router to its factory default router settings. That means you'll have to set up your password, network name (SSID), and more all over again.
A reset restores your modem to its factory default settings. It will also erase any customized settings you may have changed, including static IP address setup, DNS, personalized password, WiFi settings, routing and DHCP settings.
A modem is a box that connects your home network to your internet service provider, or ISP. A router is a box that lets all of your wired and wireless devices use that internet connection at once and allows them to talk to one another directly.
