Hi

You can reset the device through RS232 port then please follow the below steps.

You need a laptop with Console port and a console cable for EOC-8610 EXT, You really dont need the IP address if you want to do it via console (RS232) interface.

1. Connect the console cable one end to EOC-8610 EXT RS232 port and other end to Laptop serial port.
2. Open Hyper terminal and select com-port option and then provide the username and password for the device management.
3. Go inside the system menu and select Reset Factory default.

Remember if u set to load the factory default settings, the device will loose its config and will boot up with factory default configuration.

When you push the reset button, you reset the network configuration to factory default. Now you have to reconfigure the unit to re-establish the network routing and addressing for your home network, the same way you configured it when you first got it. Its default address is either 192.168.1.1 or 192.168.1.2, depending on whether it was in bridge or AP mode when you reset it.

The devices can be misconfigured or damaged.
Check if radio working fine, perform a site sruvay with a laptop (wireless).

Try address 192.168.1.1 in most cases this is default IP for the routers.

The seller fibbed. All of these units require configuration before they will operate. Configuration instructions are contained in the user manual:

Resetting the older beige Engenius radios requires a screwdriver and a USB-to-serial cable. You must unscrew the small plate at the bottom, which covers a serial connector. Plug the serial cable into it and then into your computer. Follow these instructions to perform the reset:

I have reset lots of these using the manufacturer's instructions.
Plug in the serial cable before powering on the unit. When you power on the unit, you should be able to see a log of what the unit is doing. If you can't, then your parity, bits, speed, etc. in Hyperterminal are set wrong.
When the unit stops logging (usually with a #), type in
flash reset (and hit the return key)
You should see a bunch more logging, indicating that the unit is shutting down and rebooting. After that, you should be able to log into the unit at 192.168.1.1 with admin/admin or admin/(blank).

Are you saving your settings when you exit the setup screen?
