Hi  @Procorp 

Is the first EAP245 under defualt config?

Are there any VLAN settings on the network?

Normally, we can get internet access from the ETH2 port under default settings.

What IP address will the wireless clients connecting to EAP245-2 get? 

You mentioned that a PC works with the port; did you use the same cable to test?

 Thank you for your kind response @Vincent-TP

Yes

Are there any VLAN settings on the network?

No all are in default VLAN 1

What IP address will the wireless clients connecting to EAP245-2 get? 

The same IP addresses that the EAP245-1 will provide from Netgear's DHCP Server

You mentioned that a PC works with the port; did you use the same cable to test?

Yes I have tested with the same cable

 Hi @Procorp 

So the clients will get correct IP addresses but have no Internet?

Please use ping tool to ping the following IP addresses in order and let us know the results:

The IP address of EAP245-2;

The IP address of EAP245-2;

The IP address of the main router;

The gateway IP address;

8.8.8.8;

google.com

One more test you can try:

Swap the connection of the two EAP units and see if the issue comes with the EAP unit, or the location.

 Hi @Vincent-TP

No. This is the exact problem, neither the EAP245-2 nor the clients of EAP245-2 are getting IP from DHCP. I have tried giving static IP to AP and clients, but still not able to ping the gateway or get internet connections. 

The IP address of EAP245-1;

If DHCP then no, if Static also no

The IP address of EAP245-2;

If DHCP then no, if Static then yes

The IP address of the main router;

No

The gateway IP address;

8.8.8.8;

google.com

No

Swap the connection of the two EAP units and see if the issue comes with the EAP unit, or the location.

Done but the problem is not resolved. Same thing is happening

Hi @Procorp,

Any way to verify that the POE injector is not the problem?  I don't think the 245 has a DC power option so maybe you can power the EAP245-2 from an isolated port on your switch to prevent a loopback and then connect the two EAPs together by their non-POE ports.
