Sometimes, your EAP may become bricked during a firmware upgrade. If this happens, you can use the Firmware Recovery Mode of the EAP to recover its firmware and restore functionality.

 

Note: if the model of EAP doesn’t support firmware recovery or your bricked EAP cannot enter recovery mode, you may submit a ticket email to our technical support team through here for further support.

 

Working Principle

 

Each device has a mechanism to check if it can boot successfully. When a device's system has crashed and it cannot boot successfully, we can hold the reset button for 5 to 8 seconds until the device enters Recovery Mode. The device will then automatically launch an HTTP server to display the Recovery page. We can then type the device's IP address into a web browser and load a working firmware onto the system.

 

Experiment Equipment

 

• 1 x PC
• 1 x Switch (TL-SG2210P)
• 1 x EAP (EAP245) with PoE adapter
• 1 x Clip (or other tools that can hold the reset button of the device)
• Ethernet Cables

 

Network Topology

 

 

 

 

 

Note: The DHCP server shouldn’t be included in any topology.

 

 

Configuration Steps

An EAP245 is used as the example for this guide.
 

Set Static IP address for the PC

 

1. Open your PC, go to Control Panel > Network and Internet > Network and Sharing Center > Change adapter settings > find your Ethernet Adapter and right-click it to go to Properties.

 

 

2. Double-click Internet Protocol Version4 (TCP/IPv4) in the item list > choose Use the Following IP address and set as rules below.

 

Note:

• If you are using EAP245 v3/EAP265HD v1, set the IP address/Subnet mask as 192.168.1.100/ 255.255.255.0.
• If you are using other EAPs, set the IP address/Subnet mask as 192.168.0.100/ 255.255.255.0.

 

 

 

Firmware Recovery 

 

1. Download the firmware of EAP from the official website and unzip the compressed file.

2. Prepare the PoE adapter for EAP.

3. Connect your PC to the LAN port of the PoE adapter.

4. Hold down the reset button of EAP.

5. Connect the EAP to the POE port of the PoE adapter.

6. Wait until LED is on to release the reset button.

7. Open a browser->input 192.168.1.1 (If you are using models out of EAP245v3/265HDV1, input 192.168.0.254 here) in the address bar and enter it.                                                              

Note: please make sure you use HTTP when accessing the IP address, otherwise the connection will be refused.

8. Choose the firmware you downloaded before.

9. Press Upgrade.

 

 

Verification

 

After firmware recovery, the device will use the firmware version you downloaded. You could check it on the Controller or Standalone page.
