I have tried loading this new Firmware update that I downloaded from Dlink's support web-site. 
Using a hard Wired Connection Port 1-4 directly from my pc I try uploading the Firmware file dir615_revC_firmware_311NA.zip from the tools-firmware menu 
upload. The file partially loads then fails? now is this because I am uploading from 
Rev 3.01 to 3.11NA. Meaning do I need to upload the intermediate firware updates  between 3.01 & 3.11NA  before uploading or am I doing some thing wrong?
Thanks
