I have a problem with my Wiz750sr module. first when i connected the status in the configuration tool was “OPEN”. I clicked on “UPDATE” for installing the latest firmware. Then there was an error showing “firmware was not installed” . So two leds(green & Blue ) starts to blink continuously for a very long time. I tried reloading the firmware, but it was not a success. So I searched the net and find that firmware can be uploaded through ISP Tool. So I connected the device in ISP Tool and gave the path of the firmware there and clicked on the ISP button. Then it starts to load memory and shows a dialogue box that “Download Completed” not firmware installed. After that the led’s start to stop blinking and i couldn’t even find my device in the configuration tool or in cmd windows. I used WIZnet MAC tool and entered the MAC ID of the device and Clicked the button" WRITE MAC" . It shown “READ MAC ADDRESS”,“FINISH WRITE MAC ADDRESS”. I tried many methods to make the device to recognize by the configuration tool and to upload the firmware. But it was a not a success. Not the present condition is that the configuration tool cannot recognize the device, no led’s blinking(except the red led for the power), not installed the firmware.
If anyone sees this please reply the solution. It will be a help for me.
