Hi, I can fix your ESP32 Wi-Fi instability and ensure a rock-solid connection that survives your 24-hour stress test without drops. MY APPROACH - Root Cause Analysis: Analyze your serial logs and event callbacks to identify the specific disconnect reason (e.g., Beacon timeouts, DHCP lease failures, or Power Save mode conflicts). - Logic Hardening: Implement a robust Event-Driven Reconnection Engine. This includes disabling aggressive Modem Sleep (WIFI_PS_NONE), handling specific WIFI_REASON codes, and implementing an exponential backoff to prevent driver wedging. - Optimization: Fine-tune DHCP handling and esp_netif configurations to ensure fast re-association and stable IP retention on 2.4 GHz networks. DELIVERABLES Annotated Source Code: Your original file with every change clearly marked and explained via comments. Technical Note (1–2 pages): A clear breakdown of the identified root cause and why the implemented remedy ensures long-term stability. Stress-Test Script: A simple tool/procedure to verify reconnection speed and log 24-hour uptime. EXPERIENCE I have solved "flaky Wi-Fi" issues for dozens of ESP32-based industrial and consumer products, specifically focusing on reliability in noisy 2.4 GHz home environments. ACCEPTANCE CRITERIA The project is complete only when the board maintains a continuous connection for 24 hours on your network. I am Ready to start immediately once you share the code and logs.

@elect2eng

Hello, Can you please send me your code so that I can try with my hotspot and see the performance . Did you try your esp32 with other wireless hotspot. Is there frequent data updates or the connection is stagnant without data transfer? I need to check what other functionalities are added. What we can do is to enable debug messages to spot the reason for failure.

@Shrutibimpl

Hello, I will troubleshoot and fix the connection instability issues on your ESP32-based product to ensure it maintains a steady Wi-Fi link. I will conduct a thorough review of your existing codebase, focusing specifically on the Wi-Fi connection logic, serial logs, event callbacks, power-saving configurations, and DHCP handling. The core of the task is to identify and fix the underlying cause of the frequent disconnections and slow re-association time. I will deliver clear, working code fixes that prioritize stability and reliability. 1) Which specific framework (e.g., Arduino-ESP32, ESP-IDF) is the existing codebase written in? 2) What is the highest measured RSSI value (signal strength) that the device sees when it successfully connects? 3) Are you currently using a specific low-power mode (e.g., Modem-sleep, Light-sleep) on the ESP32? Thanks, Bharat

@nabeelraza1993

Hello sir, ESP32 Wi-Fi drops almost always come down to a few fixable culprits event handling gaps, aggressive power-save defaults, router compatibility quirks (DTIM/beacon timing), DHCP renew edge cases, or reconnect logic that blocks and misses events. Well, what I can do for you is review your existing ESP32 codebase and harden it into a 24-hour stable 2.4 GHz connection: correct Wi-Fi event callbacks, robust reconnect strategy, sensible power-save settings, clean DHCP/IP handling, and logging that proves exactly why the link was failing and why the fix works. In fact, I’ve debugged “works until it doesn’t” embedded connectivity by instrumenting the full Wi-Fi state machine , then eliminating the common failure patterns: blocking calls inside callbacks, missed reconnect triggers, and sleep misalignment that causes periodic dropouts.

@engrhasan01

Hi, I’m an experienced Electronics Engineer with strong hands-on expertise in ESP32 firmware, Wi-Fi stack stability, and embedded network debugging. I have worked extensively on ESP32-based products where long-term Wi-Fi reliability was critical, including IoT and always-connected systems. For your project, I will carefully review your existing codebase to identify the exact causes of frequent Wi-Fi disconnectswhether they stem from event handling, reconnection logic, power-saving modes, DHCP timeouts, or improper use of the ESP-IDF/Arduino Wi-Fi APIs. I will focus on eliminating unnecessary resets, improving event-driven reconnection behavior, and ensuring the device recovers cleanly from temporary signal or router-side issues. All fixes will be clearly annotated directly in your source code so every modification is transparent and easy to maintain. I will also provide a concise technical report explaining the root cause, why the instability occurred, and how the applied solution resolves it. Finally, I’ll include a simple stress-test procedure or script so you can independently verify 24-hour uninterrupted connectivity on your home 2.4 GHz network. My goal is a stable, production-ready Wi-Fi connection—not trial-and-error tweaks—so your device remains reliably online.

I can resolve the Wi-Fi stability issue on your ESP32 using a combined hardware and firmware approach. I have hands-on experience with ESP32-based products, covering schematic-level hardware review (power integrity, RF considerations, antenna layout, and decoupling) as well as bare-metal and RTOS-based firmware development. I will analyze your existing code to identify causes of frequent disconnects and slow re-association on your 2.4 GHz network, including Wi-Fi event handling, reconnection logic, power-saving modes, DHCP behavior, and serial logs. Where needed, I will also verify that hardware-side factors are not undermining link stability. I will deliver your original source with all changes clearly annotated, a concise technical note explaining the root cause and fix, and a simple reconnection stress-test procedure you can replicate. The work will be considered complete once the board maintains a continuous Wi-Fi connection for 24 hours without a single drop.
