WNCE2001 power led blinking green and no connection

[ Edited ]

Hello,

I have a WNCE2001 wireless adapter that has worked for couple of months.

Now, the power LED is blinking green instead of being solid... usb powered or AC plugged...

I tried to access to it throught http://www.mywifiext.net but cannot connect.

Factory reset didn't worked.

I tried to push again the firmware using "tftp -i ip@ put firmware_file" following instructions found here : http://kb.netgear.com/app/answers/detail/a_id/18989/~/router-power-led-blinks-slowly-and-router-no-l...

Anyone got an idea why it is doing that? what could I do to fix it ?

Re: WNCE2001 power led blinking green and no connection

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.

Re: WNCE2001 power led blinking green and no connection

I dont know what that blinking means.

All I could find on the Net was a power LED blinking green on a router and it seems it was a firmware corruption.

No idea what the cause was though. Maybe a power failure or a power peak...


I have contacted netgear support as the unit was still on warranty, they make me reset the device but nothing changed. So they issued a RMA and we will proceed to an exchange of the unit.

Re: WNCE2001 power led blinking green and no connection

This is the conclusion I have come to about the blinking green led via trial and error; poor signal strength.

Re: WNCE2001 power led blinking green and no connection

This is the conclusion I have come to about the blinking green led via trial and error; poor signal strength. I had moved the unit too far and it would not connect and just blink but moving closer achieved a solid wifi led.

Re: WNCE2001 power led blinking green and no connection

The adapter suddenly stopped working. When switched on, performs a sort of quick check and the LED power switch quickly from red to amber to end in green. At this point begins to flash without stopping. The LED is used to power a regular basis if a cable is connected but the adapter is in fact unusable.
I tried to connect to the GUI in several ways but I did not succeed. I tried using direct ip set on the network card, I tried to DHCP, I tried using the link www.mywifiext.net and variations without success.

Is there a way to reflash the device?

Re: WNCE2001 power led blinking green and no connection

I have the same problem. Since couple of days ago, it started to connect to network after loads of on/off switching and today I gave up and wanted to reconfigure it again, but to no avail. Have the blinking power led, steady LAN and no W-Lan, ofc. Reset didn't work eather - nothing happens when pressing reset for over 5 seconds.
Please help!

Re: WNCE2001 power led blinking green and no connection

Hi everyone... just registered because i had same problem and want to share how i fixed it:

First this to note is that, as stated in first post, blinking power led is due to firmware corruption.

To fix it you have to follow this tutorial:

http://kb.netgear.com/app/answers/detail/a_id/18989/~/router-power-led-blinks-slowly-and-router-no-l...

Just few considerations:

-Default IP should be 192.168.1.251 (even if your unit is "bricked"). You can check it by installing any software like fing or lookatlan.

-tftp is by default disabled in windows vista/7... just google how to enable it.

-As stated in tutorial you have to wait some minutes (2 or 3) after firmware upload to let wnce2001 to write new firmware... when it's done it will auto-reboot.

Example of command using last firmware:
tftp -i 192.168.1.251 PUT WNCE2001-V1.0.0.26.img


Here you can find last firmwares:
http://support.netgear.com/product/WNCE2001

Hope this may help someone

Re: WNCE2001 power led blinking green and no connection

I just registered here aswell to help you with your problem. This reply above helped me a lot, but it was very hard to understand.
So I will make a step by step tutorial now.
Here we go!

Steps:
1. Download the last Firmware from http://support.netgear.com/product/WNCE2001
2. Open Telnet Client and TFTP client. To enable them, open Control Panel > Programs and Features > click Turn Windows features On or Off in left side > enable Client Telnet and Client TFTP then click in OK.
http://s1.directupload.net/file/d/3234/8svqfrsi_jpg.htm
3. You have to connect the WNCE2001 to the computer via LAN.
4. Deactivate your normal internet connection!
5. Configure the computer with a static IP address of 192.168.1.2 subnet mask of 255.255.255.0 and gateway of 192.168.1.1
a. From the Start button, select Control Panel > Network Connections.
b. Right click Local Area Connection and select Properties.
c. Highlight Internet Protocol (TCP/IPv4) and click Properties.
d. In the IP Configuration page, select the Use the following IP address check box and enter the IP address, subnet mask and gateway above.
6. Open a command window.
a. On Windows 7: From the Start button, go to the Search box, type cmd and press Enter.
b. type in "ping 192.168.1.251" without "" and press enter.
c. something like this will popup in the cmd window:
Ping statistics for 192.168.1.251:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 2ms, Maximum = 2ms, Average = 2ms

http://s7.directupload.net/file/d/3234/eqmkznfi_jpg.htm
7. If everything was successful until now then go on. Else repeat the steps and check for a failure.
8. Find and install your firmware.
a. Use the cd command to navigate to the directory/folder containing the firmware.
b. Run the command tftp -i 192.168.1.251 put firmware_filename, where firmware_filename is the actual name of the firmware file.
c. I did it like this:
cd C:\Users\jalloma2\Desktop\WNCE2001 Firmware Version 1.0.0.26 (NA)
*Press Enter*
tftp -i 192.168.1.251 PUT WNCE2001-V1.0.0.26NA.img
*Press Enter*
http://s1.directupload.net/file/d/3234/sl7dmutj_jpg.htm
9. Now you have to wait. It will auto-reboot. DONT DO ANYTHING :eek:
10. The power led is just green now without blinking.
11. Undo the 5. step. Delete the static IP address, subnetmask and gateway. and check Ip adress automatically.
12. Press the wps button on your router and on the WNCE2001.
13. just wait for it to connect and you are done.

Re: WNCE2001 power led blinking green and no connection

Thanks so much for the HowTo - it helped me fix my adapter as well!

With one additional step: between 7. and 8., one might have to disable any active Firewall (check your AntiVirus software for that), to allow port access for tftp.

Re: HELP! My WNCE2001 power led blinking green

I have tried the advice already given and none of the websites with info are helping: www.wifiext.net "cannot be found" and the one mentioned with the tutorial gives me files that appear useless: Release notes telling me to go to wifiext.net for the download and an img file that I cannot open not matter what I use.

I've spoken with a Netgear support person telling me that the img file is where the firmware is, but I thought that was simply an image. I was also online live chatting and got cut off.

I've wasted so much time and could use any other advice possible.

Thanks!

Re: WNCE2001 power led blinking green and no connection

When you are directly connected to wnce2001 with Ethernet cable you need to DISABLE wireless od the computer if there is one.

If you have active Internet on your computer when you use http://www.wifiext.net/ it will not reach so wifi on computer needs to disable

*.img,*.bin,*.chk is all fimrware extension Netgear uses.

Re: HELP! My WNCE2001 power led blinking green

I have tried to follow the detailed instructions (thanks jalloma2!) and all goes well until I try the tftp step when I get the message that the img file cannot be read. Is this a Firewall issue? Thanks for any help.

Re: WNCE2001 power led blinking green and no connection

I fixed this problem - My WNCE2001 unit was blinking the power LED after powering it up after a move. Here is what I did:

Download WNCE2001 WNCE2001-V1.0.0.26NA firmware from netgear and store it on my machine (unzip it so i can see the IMG file directly.

Download TftpD32 and Wireshark

Turn off my computer's WiFi, set ethernet port to IP: 192.168.1.2

Run wireshark to discover the IP that the WNCE2001 was sitting on (for me it happened to be 192.168.1.251)

Run TftpD32, use a put operation to push the firmware to the device. Set the client (in my case as 192.168.1.251:69) port 69.

Push the firmware up and wait to see if the block count goes up - if not, something is wrong, change port or IP.

Wait 10 minutes before powering off the WNCE2001 box. I thought after the transfer completed I was out of the woods as the light stopped blinking. I pulled the power and the box reverted to blinking after bootup. Eventually for me it restarted on its own and it continues to work.

Oddly, all of my old settings for my WiFi were still cached.

Hope this helps someone else!

Re: WNCE2001 power led blinking green and no connection

Many thanks to jalloma2 and others who helped me to fix the blinking power LED issue!

I think the NETGEAR Support Team, whom I addressed this problem initially, could improve their skills by reading these forums.

Best regards.
