Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

IDF version.

idf5.2.2

Espressif SoC revision.

esp32s3

Operating System used.

Windows

How did you build your project?

Command line with Make

If you are using Windows, please specify command line type.

CMD

Development Kit.

esp32s3

Power Supply used.

External 5V

What is the expected behavior?

I have tested idf 5.2.2, 5.3.1 with or without PSRAM support, when PSRAM enabled, I also tested "allocate memories of wifi and LWIP in SPRAM first" and "allow .bss in external" etc. but the result is similar:

1. If I used my phone to connect the router, and view viedo stream, it will hang up after around 5 minutes, and then you can not access any internet.
2. If I used my phone to connect the router, and not view viedo stream, but visit internet not heavily, it will hang up after a couple of hours, and then you can not access any internet.

What is the actual behavior?

it hangs up.

Steps to reproduce.

A log is like below, but it not always reports "esp-netif_lwip-ppp: pppos_input_tcpip failed with -1" before hanging up.
