Most users, when facing network errors or inability to access certain websites, opt to call a technician for network repairs. However, waiting for a technician can be time-consuming. So, why not try troubleshooting some common network errors on your own?
WAYS TO FIX NETWORK ERRORS ON COMPUTERS AND LAPTOPS
1. Limited Access Error, Wifi Signal Drops
The main reasons for the Limited Access error are IP address conflicts or issues with your network devices (modem, router, etc.), despite checking all network and power cables for a secure connection.
Resolution:
- Turn off the network device for a while, then turn it back on. This action helps the device rest and resets the IP system.
Press the Windows + R key combination to open the Run window, then type cmd and press enter. In the Command Prompt window, enter the following two commands ipconfig /release and ipconfig /renew then press enter for each command to reset the IP range for your computer.
If you have tried the above two methods and still cannot resolve the Limited Access network error on your computer, contact your network provider as the network cable to your home may be cut or the signal transmission from the service provider (ISP) may not be stable.
2. Unable to access certain blocked websites
This error is quite common when your computer can still access some website addresses but cannot access others, such as Facebook, Blogs, or many other foreign sites.
Solution: Changing your DNS can enhance internet access speed and address this issue. Google's DNS with the range 8.8.8.8 / 8.8.4.4 is stable and widely used. In cases like international fiber optic cable disruptions, you can utilize this DNS range to improve connection speed to foreign websites.
3. Unable to Connect to Network, No Network Icon Displayed on Windows
After reinstalling Windows or using a ghost image, you may not find the network icon in the system tray, and network connection fails with network errors. This commonly occurs when the computer fails to detect the network driver after Windows installation or encounters issues extracting network drivers during ghosting.
Solution: The best way to address this issue is to prepare an original set of drivers from the manufacturer. You can use Download 3DP Chip to check your network drivers and download the necessary drivers before proceeding with the installation or ghosting of Windows to prevent network driver detection issues.
4. Network Slowdown or Occasional Network Loss
Even if you encounter no issues like dot placement errors or DNS setup, sometimes you may experience a slow or even a complete loss of network connection while using your computer. This problem is mainly caused by the firewall system (Firewall) on your antivirus program, leading to this network error.
Solution: Access the Settings section of your computer's antivirus program and disable/turn off the Firewall. Alternatively, you can completely uninstall the antivirus program using Revo Uninstaller if possible.
5. Network Disconnection, Network Icon Displays a Cross
A red X appears on your system tray network icon, preventing you from accessing the Internet through any browser or software. The primary cause is a connection issue between your computer and network devices (modem, router, etc.).
Solution: Check the network cables and power cords of your network devices to ensure secure connections. Then, systematically check the signal lights on your network device to see if the light corresponding to the LAN port you've connected to your computer is lit. If the light is not on, try connecting to another port.
If your laptop can't connect to Wi-Fi, it may be because you haven't activated the Wi-Fi function on your device. Newer laptop models often come with a toggle switch or a combination of a function key (Fn) to enable/disable Wi-Fi. Follow the instructions to toggle Wi-Fi on Windows to resolve the red X network issue on your laptop.
6. Network Connection, Weak Wi-Fi Signal
Every wifi device, such as modems or routers, has a specific wifi coverage limit. Connecting to wifi farther from the network device means weaker wifi signals and network strength.
Solution: You can use a beer can as a trick to enhance wifi signals indoors or replace a modem/router with better quality. If you can't meet these two requirements, you can refer to these 10 tips to boost wifi speed.
7. Unable to Connect to the Network despite Stable Signal Lights
Suddenly, one day, you find yourself unable to access the internet through any browser or any software with network connection, even though you've checked all the jacks, the signal lights are fully lit, the network icon is normal, etc. It might be because you unintentionally set up a 'dead' or non-existent proxy address, causing your computer's requests to not reach the destination.
Solution: Go to Control Panel, navigate to Network and Sharing Center, and select Internet Options.
In the Internet Properties window, switch to the Connections tab and choose Lan Settings. Check the Automatically detect settings box and uncheck Use a proxy server for your LAN, then click OK. This will enable the system to automatically use the default proxy settings, ensuring normal network connectivity.
