Unable to upgrade the existing R500 AP with latest Unleased firmware.

I am always getting an error as Failed to download the image upgrade information. The server is not reachable or the file does not exist.

Current firmware version: 200.1.9.12.62

Hello Nat,

You are right I am not able to ping google.com or any other domain. Please check the below images.
Right now AP is just an intermediator for clients - laptops, mobile to connect via AP and access internet via the load balancer.
DHCP is allocated by TPLink load balancer as I can manage security aspects from the load balancer to manage route the traffic to multiple ISP or block the user from mac based filtering or allocation IP on basis of IP-MAC binding etc.

I think this could be the reason of firmware update may be.

Yes, this is the reason as to why you are not able to upgrade using online method. The alternate way is to do via local upgrade. Since you are running older version you have two choices. 

1.  Factory reset the AP and then upgrade at the very first screen. I am assuming you know how to get back to factory-reset AP. If not please refer to "Quick Start Guide" for Unleashed. It is very simple or you can also see on youtube videos.

2. SSH into the AP and then use CLI to do the upgrade. It is recommended to factory-reset the AP before doing the upgrade via CLI.

fw set host
fw set proto tftp 
fw set control < Unleashed software image file name>
fw show  - this command is to ensure your parameters are set right
fw update - this will start the upgrade procecss
