IP Address Clash

Guggsy

I brought 3 Reolink E1 pro cameras , with ethernet ports. I initially had the 2 cameras setup on my WIFI network, but today decided to put 1 of them that were both on the same wifi network, hard wired. So one is still using the WIFI and the other is now hard wired. My problem was that even though 1 of the camera's was hard wired the IP address clashed with the other camera which was on the WIFI. Both cameras kept disconnecting and kept saying wrong password, due to the IP address clash.

All I had done was added a unmanaged switch to my second router and hard wired my camera into the switch, but for some reason it did not change IP address on the camera so I had two cameras on the same IP address. even though they were working fine when they where both on the Same WIFI network, using WIFI.

To solve the issue I had to manually change the IP address on one of the cameras, and now they stay connected and no Password errors. DHCP is enabled on both cameras, so they both should have automatically had a unique IP address automatically. But this was not the case.

Please can some explain to me why this may have happened when I hard wired the camera.

The 2nd router has DHCP disabled, as my 1st router automatically assigns IP addresses. I have various items hard wired into my 2nd router and Items that use wifi all run fine. I don't understand why, when I plugged in a switch and plugged my camera into the switch it was not assigned a unique IP address automatically.

My 3rd Camera which was on another WIFI network, was also hard wired today going into a different switch with no problems. It was only the 2 cameras, that were initially on the same WIFI network, until i decided to hard wire one of them i had the IP address issue. It was as if the DHCP was not working correctly on the cameras. I even tried a factory reset on the cameras, and a reboot, of my 2nd router, but nothing worked, until i manually set the IP address, on 1 of the cameras.

Please can some one help or has anyone else had similar problems.
