@Ntidy79 KEEP AT THE TOP

@Ntidy79 Can you do a video tutorial? I can´t solve the problem 

@Ntidy79 Thank you for posting this! I had this exact problem.
The camera would respond to pings but refuse to show the UI or a video feed.

This is how I did it:
1. Connect the camera via ethernet cable. (I connected it not directly but via a network switch, and using its usual ip address.)
 

2. Start continuously pinging the camera's IP address (as assigned by your router). It should ping successfully, meaning it does not timeout.
- For windows open the Command Prompt  and use the command  `ping -t 192.168.1.1`. (and replace the ip with your ip address)
- For Mac open the terminal and use command `ping 192.168.1.1`. (and replace the ip with your ip address)
 

3. Open a browser and enter the camera's ip adress in the address bar.
 

The next steps will need to be done in quick succession:

4. Unplug the camera's power and ethernet, wait a minute and plug them back in.  (The pings will start to time-out)

5. Immediately after press the camera's reset button for ~6 seconds and release.
6. Now keep an eye on the ping command. After a while they should stop timing out. Once they do go to the next step.

7. In the browser press enter in the address bar. It should now show the camera's UI. (If not try to reload a couple of times.)

It might warn about the connection being non-private, or say something about certificates. You can safely proceed. (How this works depends on your browser)
8. Login to the camera's UI. With the username and password you have set previously. (The default was admin/admin).
9. In the UI click on to System -> Management -> Reset. You should see a progress bar.

10. After waiting out the progress bar the camera was back alive for me. I just had to reconfigure my settings.

I hope this might help someone.

@Ntidy79 Thanks it worked just perfect! Hate TP-Link... they do not provide support at all. I promise I'll never buy products from this brand ever.

Instead of helping they blame you for posting this workaround...

I understand why they told me not to buy their products

Hey, bro.

Nice sharing.

It is very amazing and  I would try to take it for reference to fix my old NC220 to see if I am lucky enough.

Thanks

i tested "quicly" all thing i see here, but no luck

just power off you camera, unplug your cable or turn off your wireless (mean that disconnect internet)

power up the camera, when you hear the night vision starting, push the reset button for 5 sec, and it working again and be reset

have a nice evening

Thank you !

I turn off all modem and wifi router  

Then power up the camera, when hear the night vision starting, push the reset button for 5 sec, it become factory reset.

Then we must start over again like it's new again.

It's work for my NC260 which nearly throw away to trash bin

Bravo !!

I had exactly the same experience.

My cameras seemed to get worse over time with not connecting and showing offline via app.

First one then the other. Was about to go out and buy two new cameras.

I couldnt seem to get the internal web page working with the above tips

however tried the process of waiting until camera was on (clicking noise and red lights just before the green)

pressing the reset button for 6 seconds and this factory reset the camera

From there i was able to add the cameras again via the phone app and get it setup on wifi.

They seem pretty rock solid again now
