Two D-Link DAP-2553 Access Points: #1 is DHCP server, #2 doesn't see it - clients fail

I have two of these access points. They are both on the latest firmware. #1 of 2 is the DHCP server for that LAN.

Device #1 has a static address 172.16.0.5 (SSID is 'fitness')
Device #2 has a static address 172.16.0.4 (SSID is 'SWcorner')

My WiFi phones and tablets can see both access points by their SSIDs. If a device signs on to device #1, it gets an IP address and everything works wonderfully. If a device signs on to device #2, the device will hang on 'obtaining IP address'.

It's the same LAN, and the same subnet. Both D-Link devices are physically connected to the same switch.

Why aren't client devices getting an address from device#1 when they connect to device#2?

The devices should get DHCP addresses from the main DHCP server. What is that? Device 1 ?

If so, on Device 2, turn DHCP OFF. Then devices attached to Device 2 should get an IP from the DHCP server.

Device#1 is the DHCP server and is the only DHCP server on the LAN.
Device#2 has DHCP disabled.

Thank you for the added information.

Make sure the Ethernet cable from Device 1 to Device 2 plugs into a LAN port on Device 2 (not the WAN port).

So then in summary, Device 2 has a static IP on the LAN, uses a LAN port to connect to the LAN (Device 1) and has DHCP turned OFF.  

This should work (and it does work for me in my setup).

Will You Be GDPR Compliant by 5/28/2018?

GDPR? That's a regulation for the European Union. But, if you collect data from customers or employees within the EU, then you need to know about GDPR and make sure your organization is compliant by May 2018. Check out our preparation checklist to make sure you're on track today!

Being 'access points', and not routers, they only have one RJ-45 port, for the LAN.

Yes, I agree that it should work. It's driving me a little crazy.

Being 'access points', and not routers

I suggest you get a proper router to form your network and let it be the DHCP server.

Then hook up as suggested above:  Use a static IP for the access point on the LAN, connect the one LAN port of the access point to  the LAN, and be sure DHCP is turned OFF.

Start with one access point (Device 1 because you know it is working) and ensure it works as above. Assuming it does, add the second access point.

Well, I heard back from D-link and the answer is that the DAP-2553 only hands out leases to wireless devices that connect to (through?) it. In my experience, it will hand out a DHCP lease to client devices on the WIRED LAN. It will not provide leases to devices connected wirelessly through device#2.

Oh well, I'll just move the DHCP duties to my firewall appliance.  I had been trying to avoid that because it is a little harder to configure.

I've requested that this question be closed as follows:

Accepted answer: 0 points for oakie22's comment #a39920932

for the following reason:

IDK if this behavior is unique to this particular model, or is common in other hardware. The only information that closed the issue came from D-Link.

I suggested the very same thing in my post http://#a39913815 , specifically get a router and let it be DHCP server.

So I think I have provided the answer here.
