This sounds like you have two DHCP servers.   Ideally the Deco should be the only DHCP used on the LAN (192.168.68.x)

 

The 192.168.178.x is usually from a fritz box router, so may be coming from your ISP router..   just ensure that the only LAN connection from your ISP router is into the Deco.   Plugging anything else into the ISP router will cause it to get the wrong DHCP

 

 

Thanks for your replies. Sounds logic, I turned off WiFi on my ISP-router, but didn't turn off DHCP.

 

Basically I wouldn't mind having DHCP through my ISP-router, which would mean I have to change operation mode of the Deco in "Access Point". This way I could also have more LAN-ports occupied on my ISP-router. Correct?

 

If I want to have my Deco to do the DHCP I have to turn off DHCP on my ISP-router, but then I can only have one LAN-port occupied on the ISP-router. Correct?

 

Most of my network relying equipment is still wired at the moment. Is it most logic then that I use DHCP on my ISP-router and switch my Deco's to "Access-Point-mode"?

 

My Home Assistant devices will be a mix between Zigbee and WiFi.

Yeah pretty much.  You will only be able to use the LAN ports of your router if its the DHCP server.  When using Deco in router mode (deco being dhcp) then you are best not using the LAN ports on the ISP Router, else you will get a different address range.

Yes.  That one LAN port would be the port connected to the Deco.   Everything else would have to go downstream from that Deco device.

If LAN port space is your issue, then yes.   Or add a cheap 8 port switch where you need one connected to the Deco

 

 

  @Philbert Thanks for the clear answer !!

 

I use my ISP-router for the main distribution.

 

LAN-setup

ISP LAN 2	8p-Switch-1	TV
		Receiver
		ISP-recorder
		Media-PC
		Apple-TV
		Philips Hue
		IKEA Bridge
ISP LAN 1	Deco1	8p-switch-2	Deco2
			Octoprint (Rpi)
			Work-laptop
			Mac-Mini
			Miner
			Printer
			Device
ISP LAN 3	Surveillance Cam

 

As you can tell, it's pretty full. I'm thinking of changing the order of the 8p-switch-2 and Deco2. I'm trying to remember if I did that before and might not have worked.

 

As a conclusion: There were 2 DHCP-servers active on the network, which is solved now. Maybe I'll check in future to see which device is easiest to manage in regards of the combination of Fixed IP and DHCP because of some Home Automation issues.

Still a problem on the network. When I look on my laptop that is connected wireless to the Deco1 I only see the devices that are connected to the Deco1 through the 8p-switch-2. I don't see the TV etc that are connected to 8p-Switch-1. When I check the Media-PC I see all the devices connected to the network. What did I do wrong in this network? What should I change to get everything to work? The issue is that I con't get access to the Media-PC that is running Home Assistant from anywhere in the network.

Looking at the setup you posted in the update before, the ISP router is basically the backbone LAN connection and this isnt always ideal.  

 

Try a quick test, switch to switch and see if you can then see the other devices.  Routers should not really be used for LAN traffic unless it is going to the WAN, yes technically nothing wrong with it but switches are a better option

 

Test switch to switch and see if that sorts, then you know
