Requirements:

1) FW: DWL-8610_FW_v_4.3.0.2_B053.tar (Please always check our website for new release)
2) PuTTY - http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
3) Tftp Server http://tftpd32.jounin.net/tftpd32_download.html (Install the “Standard Editiion” – depending on plataform 32 or 64 bit)

Step 9 – Due to this is a SSH connection and not Console, the session you have with PuTTy will have terminated and no screen feedback will be shown on the progress. 

To check when the upgrade has completed go to “Advanced Settings”

WLAN > Administration > AP Management > Advanced Settings

Click “Refresh” until the “Debug” status shows “Disabled” NOTE: The AP will disappear from the above list… the AP is in “Reboot” Mode and will return.

Once you have the above status “Disabled”, then the AP has successfully been upgraded. 

Step 10 – To confirm this, you may go to “Managed AP Status”

WLAN > Monitoring > Access Point > Managed AP Status
