15.9% of Australians report having their internet impacted by connectivity issues. This affects both personal and professional lives, as most businesses have transitioned to a remote or hybrid setup, making internet connectivity a vital part of one's career.
To address this issue, some opt to seek professional help. While helpful, seeking help is not always reliable since help might not always be available.
This is why it's important to know how to do basic troubleshooting to fix common network issues. To do so, you'll also need knowledge of the common internet problems and what causes them.
How to Fix Common Wi-Fi Network Issues
There isn’t a single way to fix network issues, since it varies per case. However, you can troubleshoot most of them by following the steps below:
1. Check the network status by clicking the network icon and making sure the Wi-Fi is turned on. Also, ensure Airplane Mode is turned off.2. In the Settings app, select Network & Internet > Wi-Fi > Manage known networks. Click your network, then press Forget.
3. Unplug and restart your modem and wireless router.
4. Connect to the same network on a different device. If you can connect, the issue is likely your device.
5. Try running network commands to reset the TCP/IP stack manually. To do so, follow the steps below:
- Press Win, type Command Prompt, then Enter. Type and enter the following commands:
- Type netsh winsock reset and select Enter.
- Type netsh int ip reset and select Enter.
- Type ipconfig /release and select Enter.
- Type ipconfig /renew and select Enter.
- Type ipconfig /flushdns and select Enter.
7. Restart your PC.
Common Internet Connection Problems
Common internet connection problems include slow connection speed, Wi-Fi option missing and dropping frequently, limited connectivity, and authentication problems.
Connected to the Internet but Slow Speed
A slow internet connection is still possible even when properly connected to the Wi-Fi. This issue is often caused by network congestion or a background application consuming bandwidth.
To remedy the issue, try disconnecting unused devices and closing unnecessary apps. Move closer to the router and run a speed test to see if the issue is with your ISP.
Wi-Fi Option Is Missing
The Wi-Fi option may go missing on your device because of disabled network settings or system errors. There are numerous ways to fix the issue, including restarting your device or running a system update.
In some cases, resetting network settings may restore the missing option as well.
Wi-Fi Connection Dropping Frequently
Weak signal strength, interference, router issues, and the like all could cause frequent disconnections.
To improve stability, it's recommended to place your router in a better location to ensure every room in your house or office has a strong signal. It's also important to keep your router firmware updated to prevent potential issues.
Limited Connectivity
Limited connectivity is when your device is connected to the network but can't access the internet. This issue often results from IP conflicts or ISP problems.
To fix this, you can restart your router, renew your IP address, or reconnect to the network. If none of those worked, it's best to consult with your ISP as soon as possible.
Wi-Fi Authentication Problem
Authentication errors happen when your device cannot verify the network credentials because of incorrect passwords or mismatched security settings. Double-check the Wi-Fi password or forget the network to resolve this problem.
Common Wi-Fi Network Issues Causes
Poor router positioning, signal interference, and network congestion are common causes of network issues.
Poor Router Positioning
A common reason for an unstable Wi-Fi signal is poor router placement. A poorly placed router, such as one behind thick walls, results in signals having difficulty reaching all areas of the space.
This means dead zones or inconsistent connectivity. For better performance, it's best to place the router in a central location, ideally an open area where the signal can spread throughout your home.
Signal Interference
Signal interference occurs when other devices disrupt your Wi-Fi signal, such as microwaves and Bluetooth devices. These devices have similar frequencies, weakening or interrupting your connection.
To minimize interference, place your router away from such devices or switch to a less crowded frequency band for a more stable connection.
Network Congestion
Network congestion happens when multiple devices are connected to the same network. This issue is more common in households or offices that have many users streaming videos or downloading files.
As a result, internet speed slows down, and performance becomes inconsistent. To improve performance, it's ideal to manage the connected devices or upgrade your internet plan as a whole.
Interference from Neighboring Networks
In populated areas like office buildings, multiple Wi-Fi networks operate close to each other, causing an overlap that results in signal interference.
This leads to slower speeds and dropped connections. Adjusting your router's settings or switching to a less congested frequency can help reduce the interference, improving connection stability.
Outdated Firmware or Hardware
Outdated router firmware or older hardware affects your network's performance and reliability. Older routers don't support newer technologies or faster internet speeds, while outdated firmware leads to bugs and connection issues.
Updating your router's firmware ensures optimal performance, while upgrading hardware provides better coverage and improved network stability.
