Accept any certificate warnings you may see, this is perfectly normal and safe

Step 2 – We first need to download the latest firmware available from our website. We are going to download for the DWL-6600AP

Step 3 – Once done, you will need to install a tftp server. You may use the following link:
http://tftpd32.jounin.net/tftpd32_download.html


Step 3 – Open the tftp server and transfer or copy the firmware you had downloaded for the APs from our site to the following destination:

Current Directory: C:\Program Files\Tftpd64

Server interfaces: 192.168.1.142 (This is the IP of where the tftp Server resides)

In our example we are going to upgrade the DWL-6600AP and use the above file. We have shortened the file name from:

DWL-6600AP_4_2_0_9_B021.tar

To

DWL4209B021.tar

Due to we have used a DWL-6600AP we need to upgrade the AP twice (because it has dual-Images)
Please note this will also apply to the following APs:

• DWL-8600Ap
• DWL-8610AP

Other supported APs the firmware upgrade will ONLY need to be once

Note: If you have a failed success, please confirm the following:

1) You have clicked “Save” in Step 6
2) No firewall or and Antivirus program blocking the tftp server
3) Network connections are correct
4) Check Cables
