Reasons for the lack of Internet connection
The main culprits when it comes to network issues are your device (computer, tablet, or smartphone) and your WiFi router.
Problems on the router side can be anything from outdated hardware to bad firmware or old infrastructure, damaged cables, intermittent signal strength, and too many people connected to the network at the same time. Although rare, it's also a good idea to checkMake sure there is no malware on your router.
If there is a problem with any of these devices, you will see errors likeConnected but no internetoNo internet connectionadverts
Below are some steps you can take when you encounter this common problem. We will deal with the simpler troubleshooting steps first, and then move on to more advanced solutions.
Rule out false alarms
Before attempting to repair your router or hardware, rule out false positives by doing the following:
- Make sure your network hardware is turned on and connected.
- Visit multiple websites because sometimes the website you are visiting might be temporarily offline, so you end up assuming your connection is faulty.
- Confirm that your other devices can connect successfully. If it's just your computer or mobile device, it could be a misconfiguration on that particular device. If not all devices are connected to the Internet, the problem may be with the network devices.
- Change to a wired connection, if available, or try a different connection. If you can get online with any of these settings, your router is probably faulty or there is a problem with the connection between your ISP and your home or office, or with the ISP's connection.
- Restart your computer to fix temporary software errors and try connecting again.
- Make sure your WiFi is turned on or enabled on your device. Most laptops have a WiFi button or switch which, when turned off, can result in you not having internet access.
- Turn off airplane mode if it's on. You can do this from the Airplane Mode button on your laptop or from Action Center for a Windows PC.
- Make sure you are using the correct SSID (router name) and security key. Re-enter the WiFi password and try connecting again. It is possible that you have changed it and are using the old password.
- Relocate your router or computer. This helps maintain a strong signal between the two devices and prevents connection issues. You can also buy a range extender to get strong signals at all times.
- Contact your ISP if your account is locked. This can happen when you violate the terms of service, exceed bandwidth limits, or fail to update/pay your subscription fees.
Check the router's LEDs
Various status lights are displayed on the front of the router, which have different names depending on the model. These include the Wireless LED, the Ethernet LED (for wired networks), the Transmit/Receive LEDs (which flash rapidly), and the Ready/Serving/Connect LEDs.
check if theReady/Service/ConnectThe lights are solid, indicating a good connection. If it is off or blinking, there is a problem with the connection. But if it's still solid and there's no internet connection, check with your ISP to see if there's an outage.
Restart the modem and router
To do this, unplug your modem and router and leave them unplugged for about two minutes.
Then plug in the modem, let it initialize, and plug in the router. Wait a few minutes for both devices to start up and confirm that they are working properly. This will help to reset any underlying issues and clear the contents of the router's memory.
If none of them have lights, it's probably a hardware problem. If you still don't have an Internet connection after restarting your modem and router, try the next step.
Run the Windows Network Troubleshooter
If your connection problem affects multiple devices, this step is not necessary. However, if it's just your Windows computer, there may be a problem with your network settings.
- OpenSettings > Network and Internet.
- CliqueState.
- ChooseNetwork Troubleshootingand follow the steps to diagnose and fix the problem. It may not fix everything, but it will fix most network related issues.
Check IP address
It is possible to connect to your WiFi router and still not have an Internet connection.
This happens when there is a problem connecting the router to your ISP to make it work on the network, but you don't have a valid public IP address because you can't access the Internet. As a result, you cannot send or request data over the Internet.
- Login to your router and go toSettings > Status(or network status) to verify that the IP address is valid. When the state saysOutsideodisabled person, and there are no numbers for the IP address, the router does not obtain an IP address from your ISP.
- You can request a new IP address using theRenew(or similar). If that doesn't work, contact your ISP for more information, as the problem may come from your ISP.
Another way to change your IP address is to get it automatically. This is useful if your device is configured to use a static IP address, but your router doesn't allow it on the network, or if the address is for the wrong network.
- If you are using Windows, go toPanel de control > Red e Internet.If you're in icon view, just click Network and Sharing Center.
- CliqueNetwork and Sharing Center > Change adapter settingsand double click on the connection. Depending on how you connect to the Internet, click Ethernet or Wi-Fi.
- ChooseCharacteristicsand then double clickInternet Protocol version 4 or IPv4.
- At this point you can change the IP address (but it will remain static) or select itObtain an IP address automaticallyfor the router to automatically assign one to your computer.
check network card
Your network card could also be causing internet connection issues, so you may want to troubleshoot to rule out issues.
- the right button of the mouseHome > Device Manager
- expand thisnetwork adaptercategory and look for a yellow exclamation point next to your network adapter. If there isn't one, the NIC is working fine, but if you see the exclamation point, right-click and select it.disable device.
- Wait about two minutes and right clickNetwork adapters > Enable Device. Check if the bookmark is gone and try the internet connection again.
If the mark is still there, there may be a problem with the network card. If this happens, either restart your computer or take it to a professional computer technician for repair or replacement.
Check MAC address filtering
If your router has MAC address filtering configured, you may not have access to the Internet. This setting prevents devices from connecting to the router if they do not have a specific MAC address.
The easiest way to resolve this is to add your MAC address to the allow list.
Redefinir TCP/IP
TCP/IP is a suite of protocols that connect network devices over the Internet and define how data is exchanged. Resetting TCP/IP requires entering a few commands at a command prompt.
- Typecmdin the search bar and selectCommand Prompt > Run as administrator.
- Typenetsh int ip redefinirand press Enter. Wait for it to complete and exit the command prompt. Reboot your computer once you're done.
Clear DNS
This method also involves the use of a command prompt.
- Type CMD in the search bar and right clickCommand Prompt > Run as administrator.
- Forbiddenipconfig /flushdnsto update and reset your computer's DNS settings, and restart your PC to verify that your Internet connection is restored.
Disable security software
Your computer's firewall and antivirus program may prevent you from connecting.
Firewalls prevent unwanted network traffic from interfering with the normal functions of your computer, but they can also malfunction and block actual traffic. Likewise, two firewalls on one computer can cause conflicts and block Internet traffic.
To fix this, disable any third-party antivirus orTemporarily disable your computer's firewalland check if the connection is restored. You can also run a malware scan to rule out malware that may have interrupted your Internet connection.
Update wireless drivers and network adapter driver
Device drivers provide information about how your operating system and other software interact with specific hardware on your computer. If you don't already have an Internet connection, check for driver updates on your computer.
- the right button of the mouseHome > Device Managerand then right click and select wireless controllerupdate drivers.
- to markSautomatically check for updated driver softwareoBrowse your computer for driver softwareand then clicklook for.
You can also uninstall the driver and reinstall the correct drivers from the device manufacturer's website. After that, restart your computer and test the internet connection to see if it works.
Update the firmware of the router
Updating router firmware is different for each router, but there are some similar steps to follow. However, it's a good idea to read the device manufacturer's user guide that came with your router, or go online and search for instructions specific to your router's make and model.
- Download the correct firmware from the manufacturer's website. Go to the hardware version of the routerdownload pageand select the correct file.
- Most newer routers have a page in the admin interface that checks for firmware updates and allows you to update directly, as shown below. If not, download the firmware file and continue.
- get connectedmanagement consoleon your router and locate the Firmware section in Settings, usuallyManagementoProgressive. Confirm that the firmware version of your router you downloaded is the most recent compared to what you are currently using.
- Move the firmware file to your router. You can find instructions on how to do this in the user manual or on the website. Let the installation continue without interruption.
- Reboot the router when the process is complete.
restart your router
Canrestart your routerby pressing and holding the physical reset button (usually a small recessed hole) on your router for about 15 seconds. At this time, the router's LEDs will flash and the router will reboot.
If your router does not have this button, please login to the router and run itFactory resetin the settings panel.
restart your network
If you still don't have an Internet connection, reset your network settings.
- OpenSettings > Network and Internet > Status.
- CliqueReset Network > Reset Nowto remove all network adapters and reset network settings to default. This means you'll have to set it up again, but it might help to restore your internet connection.
If nothing worked after resetting your router and network, you probably have a faulty device. If it's your router, you can try using a USB network adapter, contact your ISP provider, or replace it entirely.
Your wireless adapter or related hardware may be faulty or your computer may need service. Similarly, your computer's operating system may be damaged, in which case you may need to wipe and reinstall everything, but this should be done as a last resort.
We hope that the steps outlined here help you resolve your connection issue. I hope you don't need to do a factory reset as most of the steps above tend to fix the problem.
