I am a Mac user and did not see any reference to how to do the fix discussed by jalloma2. However, I was able to apply this fix from a Mac.

A couple of observations.
1. I use a MacBook air without an ethernet port. I found an older MacBook pro at work that has an ethernet port and used that machine. You can also purchase a USB to Ethernet adapter at Best Buy, the Apple Store, etc. - not expensive.
2. The link to the CNET website to download the TFTP Cient has an option to download a Mac version. You can also get the tFTP client at the Apple App Store. It works!
3. When configuring your Mac, use Network in the System Preferences ("gear wheel") app. Use the same settings for IP address, etc. specified by jalloma2. NOTE: After setting the IP address manually (and be sure to turn off WiFi on your machine), I tried to ping the WNCE2001 using the Terminal utility and I could not reach the unit; message was "timed out". IGNORE THIS.
4. In the Address field in the TFTP (Send) client, use 192.168.1.251. Press "File" and navigate to where you have downloaded the Firmware and then Start. THE WNCE2001 CAN BE FLASHED WITH THE NEW FIRMWARE EVEN IF THE PING COMMAND FAILED!!!!!
5. To test the success, with wifi still off on your computer, go to "mywifiext.net" from your browser. It will open and check that your firmware is correctly loaded an correct version (V1.0.0.26NA)

Hope that helps all you Mac users out there. Would also like to add my thanks to jalloma2 for a great post. BTW, I use this unit to connect my solar panels to my wireless network for monitoring purposes.

I have the exact problem: after a few months use, the unit (WNCE2001) suddenly starts Power LED green blinking and lost connection! Tried power up with “Reset" button hold;
"reset" button after powered up;
change to a different AC outlet;
.....

No success!!

Any other brand of such "universal wifi adaptor" recommended?

Thanks

  Hi SV_Gary,
  
  Can you please confirm that your WNCE2001 is running firmware 1.0.0.26 ? Also, is your modem/router updated?
  Were you able to replicate the steps provided by other community members?
  
  I look forward to hearing back from you.
  
  Regards,

    I was able to successfully flash the firmware on the WNCE2001 to 1.0.0.26 using the methods described and brought it back to a working condition. My router, a WNR2000v4, is up to date as well at version 1.0.0.60. If you would like to send out a Nighthawk X4 or X6 for feedback and firmware tests I would be more than happy to write up an honest and technically objective eval using iPhone 6 and Surface Pro 3 wireless ac network adapters. :smileyvery-happy:
