Wifi disconnects and is unable to reconnect with WIFI_REASON_MIC_FAILURE code (IDFGH-5142)

[robertoimai]

Environment

• Module or chip used: ESP32-WROVER-E
• IDF version (run git describe --tags to find it): v4.2
• Build System: idf.py
• Compiler version (run xtensa-esp32-elf-gcc --version to find it): xtensa-esp32-elf-gcc (crosstool-NG esp-2020r3) 8.4.0
• Operating System: Windows
• (Windows only) environment type: VSCode.
• Using an IDE?: VSCode]
• Power Supply: external 3.3V

Problem Description

Module is disconnecting from wifi with reason code 14 (WIFI_REASON_MIC_FAILURE). Any attempt to reconnect will also fail. You can see from the log that the failure did take a long time to show up. About 75hrs. I saw a reference similar here: https://github.com/espressif/esp-idf/issues/5023 But it led to stale. My router is a TPLink AC1750
