Hello @murashi 

 

What is the Operation Mode of the TL-WR1502X? Is it working in Client Mode?

 

Since the Client PC has already successfully obtained a valid IP address from the main router via the TL-WR1502X, please try to ping the IP address of your main router using the How to Use the Ping Command. Kindly show us the result.

 

If you can ping your main router successfully but cannot access the internet through the TL-WR1502X, it may be due to special settings on your main router, such as IP or MAC filtering. Please check them carefully.

 

BTW, what is the model number of the main router?

hi,  @Kevin_Z 

Sorry for the late reply.


> What is the Operation Mode of the TL-WR1502X? Is it working in Client Mode?

It is working in Client Mode

 

> BTW, what is the model number of the main router?

It is an ISP-supplied router.
KAON KCM3101

 

> please try to ping the IP address of your main router

I will also inform you of the status of the TL-WR1502X's LEDs.I've attached the final results.

* Since uploading the .txt file failed, I zipped it and attached the archive instead.

 

Kindly review the attached file.

Hello @murashi, thank you a lot for sharing the ping test results.

 

You mentioned that when the WR1502X is working in Hotspot Mode or Router Mode, it connects to the ISP-supplied KAON KCM3101 properly without issues. I wonder if there is a specific concern or purpose you would prefer to use it in Client Mode for.

 

If not, you may use it in Hotspot Mode or Range Extender Mode.

hello, @Kevin_Z 

Thank you for your reply.

I will use it in one of those modes.

 

> t connects to the ISP-supplied KAON KCM3101 properly without issues

 

The issue I experienced was the lack of connection stability. I observed a persistent situation where the device disconnected a few minutes after the connection was successfully established.However, The issue is likely due to the router(ISP-supplied KAON KCM3101), so I will check if the same condition occurs using a different router.I will share an update later.
