Model: EAP225  
Hardware Version:
Firmware Version: 2.4.0 Build 20181121 Rel. 55897

Hello all,

 

I am trying to setup a network in my house with the use of access points. I have Cat6 UTP cables going up to different floors and have sockets in the wall to connect it again with a ethernet cable. When connecting a laptop all is working fine. When I connect the AP in the same manner, it does not show up in the Omada Controller.

When I connect the AP directly to the PoE switch the Omada Controller is able to find it and it works like a charm.

 

So, why can't I connect it with a cable, to my socket in the wall, which is connected to the PoE switch? It's is merely a simple extension of the ethernet cable, right?

 

Hope you can help me. Thanks in advance!

 

Kind regards,

Marlies

@Marlies, where did you connect the laptop to? To the PoE switch or to the cable's socket? If the latter, can you ping Omada Controller from the laptop? How long is the cable? When connecting the EAP, did you use the same port on the PoE switch the cable is plugged in or did you use another port?

I also think that when you connect the EAP to the socket, the AP can connect to the internet but it is not in the same subnet with the Omada Controller. 

We can manage the EAP on the Controller directly only when they are in the same subnet.

@R1D2 Thanks for your reply. I connected the EAP to the same port via the socket as when connecting directly to the PoE switch. I tried both options, different ports and same port. They still get disconnected. The cables are shorter than 20 meter. Since I created 3 sockets with a 50 meter cable.

 

PC with the controller was directly connected to the PoE switch.

 

About pinging the controller from the pc, I am unsure how. How do I ping software?

Hello @forrest , is there a way to see if this is the case?

@Marlies 

 

Just as R1D2 said, we can try to ping the EAP's IP address from the Controller host (PC). If you can ping it successfully, then they should be in the same subnet, and we will try other ways to help you. If you cannot ping it successfully, it means they are not in the same subnet. 

 

If you don't know the IP address of the EAP, you can also connect your laptop to the socket, then you can check the IP of the laptop. After that, ping the laptop on the Controller host.

@Marlies Is the AP properly powered on (what does the LED on the AP show)?

Hello Marlies, ping the host's IP the controller is running on. As forrest wrote, connect the laptop to the socket or PoE switch and you will see its IP (run command ipconfig in a command window). Then either ping the laptop from the system running the Omada controller (»server«) or ping the server from the laptop, either way will work. However, you need to find out the server's IP address to be able to ping it. If it's a Windows system, use the ipconfig command there to find out the current IP address. If it's a Linux system, use ifconfig or ip addr to do the same.

 

See https://en.wikipedia.org/wiki/Ipconfig and https://en.wikipedia.org/wiki/Ping for more information.

@forrest So, the IP's that were assigned are as followed:

 

I tried pinging 192.168.2.22 and get the following result:

 

192.168.2.13 is my laptop with the Omada controller software.

 

When connecting the EAP directly to the PoE switch I am able to ping it again and it shows connected in the Controllor page.

 

Does this mean I should remove the socket, add a connector to that cable and plug it in? It would then be directly connected via a 15m cable.

Marlies, there you have it: no connectivity over this cable. Get a cable tester for $ 15 or 20 € from Amazon and check the wiring of the cable and the socket. You can then either correct the wiring or probably you need to replace the cable.
