ESP32 Cam network problem

By default ESP32 Cam uses 192.168.0.1 as it's default IP address. Unfortunately this clashes with my router's IP address! How can I change this as I am unable to configure the camera.

RE: ESP32 Cam network problem

You mean esp32 camera in AP mode so it annouces the network? You connect to it and reconfigure device to connect to the existing network.

Otherwise you need to edit firmware on the camera to enable DHCP client or change the assigned IP address for the device (and I also recommend to write down MAC address and set static DHCP lease for it on the router), recompile the firmware  and upload to the device.

See my GitHub and printables.com for some 3d stuff that you may like.

I cant log into it. It automatically boots with wifi enabled on same ip address as my ISP router and router freaks out and thinks it's a hacking attempt. Using the locahost option doesn't work either  Trying to reconfigure it simply doesn't work - it takes me to my router log in page. That's the problem. I need to alter it before flashing the firmware.  I can't change my router ip as it would mean reconfiguring every device in the house!

Couldn't edit post. I have no clue on how to alter the firmware - I'm not a software/firmware guru and a bit late to learn in my mid 70's. I cant even remember what I had for breakfast never mind learning a new skill 😉

RE:

Can you provide photos and model details about it such as where did you get it, how do you try to connect to it?

You probably need to connect to the wifi network the camera creates via a phone and reconfigure it. This is usually default .ode for the new preconfigured devices. You are redirected to the camera web interface and then you can configure it to connect to the different wifi and after providing user/password it will try to reconnect and use DHCP to get the IP address. If it fails the after some time it will recreate its own wifi and you can try to reconfigure it again.

If you try to do it on the laptop with the ethernet cable you will get two networks with the same addresses on different interfaces and link metric will route traffic to the router over the faster link, so you would have to unplug the ethernet cable and use browser incognito mode to avoid cache in the browser.

It's an ESP32-CAM identical to the one the Github page. It was working with Prusa Connect but I changed ISP and now new router with a different ip address so I reflashed it and the camera now conflicts with my ISP router which does both my Ethernet and WiFi and it's impossible to access it without turning my router off which means no WiFi. If I do turn the router off things multiple think the camera is my router and try to connect it! Localhost via usb doesn't work either.

RE: ESP32 Cam network problem

Get the camera and the smartphone somewhere outside the range of your router and wait until the esp creates its own wifi network - connect to it via smartphone and reconfigure it.

Other idea is to change router ip and reboot the router.

Another option is to temporarily change wifi name on the router.

Or use he boot button on the camera to trigger it into a flash mode over usb.
