EAP110-OUTDOORv3 not get DHCP address
EAP110-OUTDOORv3 not get DHCP address
2021-08-25 22:58:26
Model: EAP110-Outdoor  
Hardware Version: V3
Firmware Version:

I'm trying to set up at a new site a new EAP110, but EAP does not apply offered IP address via DHCP. Other TP-Links devices working fine on other sites with the same settings.

 

DHCP log:

Do you use the Omada controller to manage this EAP? Is the DHCP server also a TP-Link router? If you can provide more details about your topology, I think we can help you further. But before that, I think you can check whether your EAP110-Out door is running the latest firmware from this link: https://www.tp-link.com/us/support/download/eap110-outdoor/#Firmware

@Somnus 

How I can connect to EAP and check for firmware update, if EAP not getting IP?

 

I using dedicated dhcp server. Also I'm tried local dhcp server in same subnet without success: dhcp server in cisco router and tftpd32.

If you didn't use omada controller, the firmware is not that important. But you can connect a laptop directly to the LAN port of the POE adapter, assign a static IP to this laptop, and use the default IP 192.168.0.253 to log into the EAP's admin page, and then you can check if the EAP is getting IP via DHCP or static IP.

Not working for me.

 

I see the MAC address of the EAP, but I don't get ARP record:

My mistake. Mixed it with OC's. Are you able to log in via 192.168.0.254?

Dear @DmitryG,

 

DmitryG wrote

@Somnus 

How I can connect to EAP and check for firmware update, if EAP not getting IP?

 

You may refer to Situation 2 from the FAQ below to log into the web UI of your EAP, then check the current firmware version.

How do I login to the web management page of the EAP Series products

 

The latest firmware of EAP110-Outdoor V3 is 5.0.2 Build 20210604, I'd suggest you install it if the current firmware it's not up to date.

Besides, please ensure the LAN Network of EAP is configured to Dynamic IP (you can check it from its web UI).

 

If you cannot log into the web UI of the EAP, please check if you can ping the EAP in the LAN, try to factory reset the EAP then try again.

 

If your concern is resolved, I'd encourage you to give feedback to the community so others can be confident of the solution.

 

Thank you so much for your cooperation and support!
