Issues with IP addressing with EAP245
I am trying to do a site upgrade from our old EAP220 to new EAP245. Our site has 14 EAP220 APs and everything works really well. We are upgrading beceause some of the EAP220 APs are starting to fail after 5 years which is to be expected. We are running into an issue with IP addressing that has us puzzled.
Here is what is occurring:
We have multiple VLANs
Each SSID is tied to a specific VLAN
Client connects to SSID and gets proper IP address according to the VLAN of the SSID
About 2 or 3 minutes later the client gets a private IP in the 169.x.x.x range
This issue does not occur with our EAP220 network that is controlled by TP-Link EAP Controller version 2.5.4.
We have also tried stand alone mode with a couple of the EAP245 APs and they see the exact same behavior.
Our DHCP server for 1 of the VLANs is our Windows Server 2019 domain controller
The DHCP server for the other VLANs is a set of Untangle routers.
Again, everything works perfectly with the EAP220 APs, we are only seeing this issue with the EAP245 APs.
