Ever frustrated with the yellow triangle with an exclamation mark over the Wi-Fi or Ethernet icon? When you move over the symbol, it will show you limited or no Internet access message. You can see this warning message during Windows 10 startup and when the Internet connection suddenly stops. When you get the ‘Limited or No Connectivity’ notification, it means that you can’t fully get connected to the web. There are many reasons why this could happen.
The below solutions may help you to restore Internet access.
1. Windows Network Diagnostics
When you see the limited or no Internet access icon on the task bar, right click on the Wi-Fi icon with warning symbol. Choose “Troubleshoot problems” option to open Windows Network Diagnostics.
Windows will check your network connection and show the possible errors like below. In most cases restarting your PC will solve this intermittent Wi-Fi connection problems.
2. Reset Network Connection
You can perform TCP/IP reset to re-establish the Internet connection. Follow these steps. Press “ Win + X” keys or right click on the Windows start menu. Select “Windows PowerShell (Admin)” option in recent Windows 10 version.
If you have earlier version of Windows then you should see “Command Prompt (Admin)” instead of PowerShell. You can reset network either in Command Prompt or in PowerShell. Inside the command window, type in: netsh int ip reset C:\resetlog.txt and hit enter. You will see the status like below asking you to restart the computer.
Reboot your computer and check whether the Internet is re-connected. If you still can’t fix the problem, use the following additional commands in the command prompt.
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
Remember to run these commands in administrator mode, otherwise you will see a message like “The requested operation requires elevation (Run as administrator)” message.
3. Wake Up Wi-Fi Adapter
By default Windows 10 turn off the network adapter when the computer is in sleep mode to save power. If your network adapter is in sleep mode, you may have connection issues when you waking the computer. Follow these steps to disable the power management option.
- Search for “device manager” and go to Device Manager in Control Panel.
- Go to “Network adapters” section and right click on your adapter and choose “Properties” option.
- Go to “Power Management” tab and disable the option “Allow the computer to turn off this device to save power”.
4. Enable Download Over Metered Connections
This solution may help you to fix the connection issue, if you use a mobile hotspot. By default Windows 10 will disable downloading of software in metered connection. You can enable this if needed using the following steps:
- Go to Windows Settings and then to Devices section.
- Enable “Download over metered connections” under “Bluetooth & other devices” section.
Restart your computer and verify that the Internet connection problem has been resolved. Remember to disable the option when you are back with wireless so that additional charge on metered connection can be avoided.
5. Restart Wi-Fi Adapter
In many cases, you can resolve the problem by restarting the adapter or modem. Follow these steps:
- Type ‘device manager’ in search and hit enter key.
- Right click on your network adapter device and choose “Disable device”.
- Restart your PC.
- Go to the device manager again and enable the networking device.
This should restart the network adapter and the connection can be restored to normal.
6. Update driver
The driver files of your adapters may get corrupted, causing intermittent connections and other issues. Downloading the latest driver files should solve the problem.
Go to Device Manager, right click on your network adapter and choose “Update driver” from the context menu. Choose ‘Search automatically for updated driver software’ and wait for the process to complete.
If the driver isn’t found, go directly to the official website of your network adapter manufacturer. Download driver for your adapter model and update manually.
7. Check For Weak Signal Or Loose Cable Connection
If your computer is connected to a wireless LAN, make sure that the signal is still strong in your spot. Remember that the network signal can weaken significantly when you change the location away from the router or modem. If you are using standard wired connections, you need to check cables and connectors, to make sure that they are not loose or disconnected.
8. Check Bridging Router Configuration
In many networks, routers can be used for bridging, with the purpose of extending Wi-Fi. If you use many routers, make sure that they have similar settings for bandwidth and channels. If one of the routers uses different settings, there will be connectivity problems in some areas of the network. You need to check the settings of bridging router to make sure that the configuration fully matches with the access point or modem settings.
9. Change to Google Public DNS
Bad DNS may contribute to poor Internet connections. Using Google Public DNS should be a good solution and it may fix your connection problems. Follow the instructions in this article to change DNS settings.
Restart you computer and check whether the problem has been resolved.
10. Disable VPN and Proxy
VPN and proxy settings will change your network settings in order to bypass the blocking from Internet Service Provider. Sometimes this settings will interrupt the Internet connection and cause limited or no Internet access issue.
So it is a good idea that you disable VPN or proxy or any additional settings that overwrites your default network settings. After disabling restart the PC and check you can access Internet without problem.
11. Contact ISP
If you have tried everything on your side, then discuss with your network administrator if administrator manages you network centrally. Otherwise contact your Internet Service Provider (ISP) to make sure that the problem isn’t on your side. Ask them to check the connection to your computer and find out where the data transmission stops.
