Model: Archer NX200  
Hardware Version: V2
Firmware Version: 1.3.0 3.0.0 v60e0.0 Build 260311 RC.45976n

Hello,


I am experiencing intermittent connection issues with my router.

The main problem is that my PC, which is connected via LAN cable, randomly loses internet access. In most cases, the issue resolves itself after around 5–10 minutes, but sometimes a router restart is required.

During these outages, the Wi-Fi connection continues to work normally on other devices. In rare cases, the opposite happens and the Wi-Fi is affected instead, but this occurs much less frequently.
 

An important detail is that even when the internet connection stops working on the PC, I am still able to access the router interface via LAN without any issues. The router itself also does not show any internet connectivity problems or other errors during these incidents.


I have already tried the following troubleshooting steps:

  • Replaced the LAN cable
  • Performed a factory reset
  • Updated the router firmware


Unfortunately, none of these steps solved the issue.


Additionally, when using a different 4G router with the same PC and cable setup, the problem does not occur.

Could someone please help me investigate this issue?


Best regards

Hi, 
Please confirm the following information for the reported phenomenon.


  1. How often does the PC lose internet connection, such as how many times a day?
  2. When the PC loses internet connection, do you have internet on another laptop if you connect it to the router via LAN cable? 
  3. When the PC loses internet connection, can it ping www.google.com or 8.8.8.8 successfully?

 

Best Regards

Hi,
Here are the instructions to use the Ping command on a PC: How to use the Ping command. Can I know why you can't use the ping command?
 

How often does the PC lose internet connection, such as how many times a day?

 

If you do not have a laptop, is there another device wired to the router? If so, when the PC has no internet, does that device work fine?

 

What's the model number and OS version of your PC?

 

Best Regards

When I tried to ping 8.8.8.8 or Google, I could not establish a connection.

I am using Windows 10 Pro Version 10.0.19045 Build 19045.

My internet provider is O2 in Germany.
I lose the connection 2–3 times per day, usually within a short period of time.

Hi, 
Can you connect another wired device to the Archer NX200 to test whether it works?
If you have another wired network adapter, you can install it on your Windows PC, connect the PC to the router via Ethernet cable, and check whether the connection is stable.
Best Regards
