1. The model number of your wireless router. - it is an Asus ZenWifi AC

2. The MAC address of the C510W - PM sent

3. The configuration page on your router that showing you have assigned a fixed IP address to the C510W, and the IP address obtained on the C510W. - PM sent

4. Your network diagram, ensure that the C510W connects to the router's Wi-Fi directly, or connects to an AP/RE. - PM sent

  @Solla-topee in the ink to the shared file area i sent you i have added a new screenshot called IP Scanner. It shows all devices on the network (wifi and ethernet) and as you can see it lists the camera at 192.168.0.127 with its correct mac address and there is also no device at its DHCP assigned IP address of 192.168.0.18

Pinging 192.168.0.18 comes back as Destination host unreachable.

Allocating the above IP is more a management thing. I reserve 192.168.0.2 - 192.168.0.30 to my reserved IP allocation and then open the rest of the subnet to DHCP dynamic allocation.

Within this I have certain IP's allocated to my cameras.

As I mentioned the other 4 Tapo cameras are fine (albeit wired etherent connected). One thing that has crossed my mind is whether the C510W hard coded the first IP it gets set when you install it. I dont want to do this but a factory reset followed by aa reinsall may then allocated it the 18 IP address. But really it shouldnt do this. There is obviously a quirk somewhere.

  @Solla-topee just for reference (and after discussions with you technical team) I did a 'remove' the camera and then set it up again. This time it has now picked up the 192.168.0.18 allocated IP address.

But maybe it should, like the other Tapo cameras I have, do this on a reboot when a fixed IP address has been assigned.

Anyone wanting to fix IP on the C510W then note they should allocate it a fixed IP BEFORE you initially set up the camera then it will find it as it goes through its setup procedure.

Of course some will ask why do you need to fix its IP at all. Well sometimes these camreas are uses with CCTV software like Ispy and Blue Iris. These will use the ip address specified. If the IP address is DHCP allocated it runs the risk of changing if the router gets restarted for whatever reason. A fixed IP means the software always uses this address.

Hi,

I noticed that when I changed my DHCP server it took a few days before the c510 was reachable again. It seems dhcp had to time out before a new ip address was accepted. (also dhcp assigned)

In the old situation I bound the ip address to the mac address on the dhcp server. So whenever the c510 asked an address he would get the bound ip address assigned

After a network change I had a new dhcp server and all cameras came back with new ip adresses ( the new dhcp server gives a complete different ip range, so the old addresses can not communicate anymore) I did not use the binding trick in the new situation. I may do that later, but simply have not looked into that yet.

Letting dhcp time out (and make sure the dhcp server is not reachable anymore)might do the trick for you for now. But the situation is not exactly the same.
