Select the Start button, then type
Restart your device.
If restarting doesn't work, switch between Wi-Fi and mobile data: 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.
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.
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.
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.
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.
Reset Your Modem and Router (Power Cycle)
Unplug the router first, then unplug the modem. Neither of them have power buttons, so it's a matter of pulling the power cord out of the back of the modem or router. Leave the devices unplugged for 30 seconds, then plug the modem back in followed by the router.
Internet (Green) - The Internet LED lights up when the router is connected to your cable or DSL modem. If the LED is flashing, the router is sending or receiving data over the Internet port. POWER (Blue/Red) - The POWER LED lights up blue when the router is powered ON.
If you're seeing slow internet speeds on Wi-Fi, but your speeds improve when plugin into your modem, the issue is probably somewhere with your router. But if your speeds are a lot slower than you should be getting, your internet service provider (ISP) may be at fault.
As mentioned before, reduced connection speeds and poor performance are key signs that your modem is starting to have problems. This can be your first warning sign that you need to get a new modem before you are left without internet connectivity due to your modem failing.
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.
Then reinsert the batteries and reconnect the power cable. Wait up to 10 minutes for everything to get reconnected. Your connection lights should now be solid (not blinking). Check your internet connection.
Router reset will wipe out all of your customized settings. Router username and password will be reset to factory default values as shown on the router label. Personalized Wi-Fi settings will be deleted, including the Wi-Fi name and password you created.
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.
The modem and router are essential in ensuring a stable and reliable connection. Without a modem, the router would not be able to connect to the internet, and without a router, devices on the network would not be able to communicate.
A modem brings internet service into the home, and the router delivers the internet to the devices in your home via WiFi or an Ethernet cable.
A router must be connected to the modem to distribute the internet connection to your devices. Some devices combine the tasks of a modem and a router these days. As a result, you won't need to purchase a separate modem and router while setting up your home internet connection.
Most companies recommend rebooting your router at least every couple of months. If you're ever wondering whether or not you could benefit from a router reboot, just go ahead and do it. There aren't any negative results from rebooting your router, and it provides quite a few positive benefits.
Summary: Should You Turn Off Your WiFi Router at Night? In a word, yes. Turning your WiFi router off at night drastically reduces exposure to unnecessary radiation. You'll also save energy in the process.
