I recently built the GalaxyRVR kit. I was able to connect to its Wifi and run the app on my iPhone. But had no camera feed. So I bought another camera and replaced the old one. But now it is not sending out the GalaxyRVR wifi. I reloaded the Arduino code. I saw the other similar post and did what it said. Here is the serial port feed: GalaxyRVR version 1.1.0 Initialzing… SET+RESET …[0;32mI (524) esp\_image: segment 5: paddr=0x0020f3b0 vaddr=0x4008d178i(a3sgdc0e [I:pte[mt neBin version(Wroom32):1.1.2 I (626) wiw: few idinf i i (Ienf ied28wtf SET+RESET …SET+RESET …[FAIL] I fear that I may need another GalaxyRVR shield.

You can try to change Wi-Fi setting to STA if you use Rover at home. If you want to use it outside you can turn on Wi-Fi access point on your iPhone, set Wi-Fi settings into Rover and enjoy!

Hello, I entered my home’s Wifi properties, but still could not connect. I think I may have zapped the GalaxyRVR Shield. Is it possible to buy one or get a replacement? Thanks, John ---

Wi-Fi connection is made by the esp32 module. Take a look on connections between esp32 and main board. Make sure that little switch is at RUN position. ---

I should have seen the Wi-Fi on the esp32 module. Thank you. Here is my situation. The esp32 module that came with the GalaxyRVR could connect but had no camera feed. I bought 2 esp32 modules from Amazon. Although their esp32 modules look the same, they cannot connect to Wi-Fi. I tried the two new cameras with the original esp32 module, but still no camera feed. So, I guess I need a esp32 module. Thank you, John Layne ---

Have you try to update the firmware of esp32 module? > **[FAQ — SunFounder GalaxyRVR Kit for Arduino 1.0 documentation](https://docs.sunfounder.com/projects/galaxy-rvr/en/latest/faq.html#how-to-update-firmware-for-esp32-cam)** ---

I updated the firmware. Now I can see the GalaxyRVR Wi-Fi, but it says the password 12345678 is incorrect. ---

Yes I know, was the same thing for me. Now you can try to set Wi-Fi as STA with your home Wi-Fi settings. It’s supposed to work now. ---

* * * 1. Update SunFounder\_AI\_Camera to version 1.1.1 (as shown in the image). 2. Update the firmware for the ESP32 CAM: [How to Update Firmware for ESP32 CAM](https://docs.sunfounder.com/projects/galaxy-rvr/en/latest/faq.html#how-to-update-firmware-for-esp32-cam) 3. Change the Wi-Fi channel: [How to Change Wi-Fi Channel](https://docs.sunfounder.com/projects/galaxy-rvr/en/latest/faq.html#how-to-change-wi-fi-channel) 4. Re-upload the zeus-car.ino code: [How to Upload the galaxy-rvr.ino Code](https://docs.sunfounder.com/projects/galaxy-rvr/en/latest/faq.html#how-to-upload-the-galaxy-rvr-ino-code) If the issue of repeated disconnections persists after trying the above methods, it is recommended to downgrade the ESP32 CAM firmware back to version 1.4.0 to see if the disconnection issue still occurs. ![d9c759e4c3f0a85a9c2b122ce4f3a4d1](https://canada1.discourse-cdn.com/flex029/uploads/sunfounder/original/2X/f/f449b4f9b527a9551c9a0ecde1103873f4dade9a.png) ---

Now I have the intermittent disconnect problem and I need to install firmware ai-camera-firmware-v1.4.0 and I have 1.4.1. Can see GalaxyRVR WiFi but it does not accept “12345678” as the password. Spent many hours trying to update the firmware with the esp32-cam board wired up to an Arduino Uno board. ARG. Is it possible to buy an esp32-cam board and camera that works?? Thanks ---
