Have you ever experienced a sudden loss of internet connection while using Windows 10 or Windows 11?
Or the connection may be interrupted frequently, requiring you to reconnect or restart your PC each time.
If you use the internet every day, frequent disconnections can be a nuisance.
This time, I would like to introduce some causes and solutions for when your internet connection is interrupted.
Frequent internet connection drops
1. IP Address Conflict
One reason your PC can't access the Internet is if it's caused by an IP address conflict on one or more devices.
An IP address conflict occurs when different devices use the exact same IP address.
Normally this doesn't happen, but occasionally an IP address conflict can occur.
In this case, you can solve the problem by simply running the following two commands:
Open a command prompt as an administrator, type the following code, and press Enter:
Learn how to open a command prompt
1. Press Windows key + R to open Run.
2. Type "cmd".
3.Shift + Ctrl + Enter Please press.
4. When the "User Account Control" message appears, click "Yes".
ipconfig /release"ipconfig /release" is the command to release the current IP configuration.
Then enter the following code and press Enter:
ipconfig /renew"ipconfig /renew" is the command that tells your PC to automatically renew its IP address.
Reclaiming the IP address will resolve the IP address conflict issue.
2. Fiber optic cable
Some people who use fiber optic cables bend the cables.
Do not bend too much, especially near the tip.
Bending at less than 90 degrees can cause signal loss, resulting in slower speeds, intermittent connections, or even breaking the cable due to excessive bending.
Fiber optic cables are long and can get in the way, so when you organize the wiring neatly, be careful not to bend them as shown below.
Be sure to avoid bending it in the following ways:
Make sure the angle near the tip is gentle and at least 90 degrees.
3. If you are connected via Wi-Fi
If you are using a Wi-Fi connection, you may experience connection interruptions or slow speeds due to a lack of signal or instability.
Connection drops are especially likely to occur in environments where you are connected to the high-speed 5GHz band.
Due to the characteristics of 5GHz, the signal will be weaker and the connection will be unstable if there are obstacles in the way, so in that case we recommend connecting to 2.4GHz.
Although 2.4GHz is slower than 5GHz, it is more resistant to obstructions and provides a stable connection. For example, if you are experiencing stuttering or crashes in online games, simply switching to 2.4GHz can often resolve the issue.
4. Router Settings
Many users probably use their Wi-Fi router with the settings as they are after purchasing it.
Although it is not widely known, the settings may cause unstable connections and slow speeds.
Check the following items and try disabling unnecessary functions or changing the settings.
- Check for firmware updates
- Be sure to update the firmware. You can expect various bug fixes and improvements.
- Change the "Transfer Strength" for 2.4GHz and 5GHz in Wireless Settings to "Medium".
- I believe the "Transfer Strength" is set to "Strong" by default. However, if it is set to "Strong," there is a very high possibility that the connection will become unstable. As the saying goes, "too much is as bad as too little." If it is too strong, it may have the opposite effect, so I recommend setting it to "Medium." In fact, in my environment, setting it to "Medium" eliminated interruptions and was more stable than "Strong."
- OFDMA/MU-MIMO
- If your device (PC or smartphone) does not support "OFDMA" and "MU-MIMO," disable them. They are likely enabled by default, so please check.
- Easy Mesh
- Are you using a third-party device that supports EasyMesh? If not, disable it. It should also be enabled by default, so please check.
Please check the Wi-Fi router settings listed above, disable any unnecessary functions, or make any changes to the settings. After doing so, be sure to restart your PC.
