Hi,

 

Model: NC210

Hardware Version: V1

Firmware Version: 1.0.9

 

They do not lose connection at the same time. It happens suddenly and it might be that one camera goes offline and others work just fine.

Wifi-signal shows "very good" in four of them. One is "good".

 

There's three meters from every single camera to wlan access points. I think that wifi signal is good and strong enough to keep devices connected. Like I said there is no other devices dropping off like these tp-link cameras do.

 

I have tried static ip's and now I'm using dhcp reservation. Changing between dynamic and static ip does not change the behavior. I also have to mention that sometimes there is like few weeks that they are online and working normally. Sometimes they drop off 5 times per day.

 

I bought them from store in Finland.

Hi,

 

I'm using Google Wifi:

It's a mesh network so channel in 2,4Ghz and 5Ghz is decided by Google wifi.

 

I bought them 8-10 months ago. They have done this from the beginning and I'm bored to unplug->plug. 

First I did have tp-link powerline extenders but cameras had exactly same problems as they do now with google mesh.

 

You mean ul and dl speed to internet. Not quite sure how it has nothing to do with this but most of the time:

UL: 20Mpbs

DL: 30Mbps

 

Have you red other topics where people are reportins same issues with different models:

Is there a problem with your version management? Could it be that you did publish version which was not properly tested and now users are testing it for your guys and reporting connectivity issues?

and today..two cameras offline..

three online..

 

It's offline, there is no ip address. Dhcp reservation is still there of course waiting for camera to get back online but camera is not active and is in offline.

Because it drops off from network it can't answer ping request, or telnet. Like said..it is offline...

If it would be in online mode like it should be ip address would be 192.168.86.17. That's normal local network ip address and normal Google Wifi LAN address pool where the ip is reserved.

 

Led status is solid green. I may be stupid but I'm 99% sure that this has nothing to do with my local network or ip address it uses or in what position planet earth is at the time when camera X goes offline. I'm 99% sure that it is your firmware which has some weird sh** going on. 

What do I need to read log file from camera? Notepad ++ did not understand log file.

Would have copy paste log file to forum but that's disabled in camera configuration page. So let's post some pictures.

 

 

Here's basic log loop.. first many lines "time changed". That seems stupid that camera logs ntp time changes in every 5min but what ever.

Then suddenly NTP is f*cked up and we go back to the year 2016. Then it starts camera modules again and changes ip to bu ip 192.168.0.10 which is not google wifi local networks ip address. So that is the moment that camera goes offline. Now I'm not sure at which point I unplugged camera and put it back on. It might be that line where it says that year is 2016 and maybe because it hasn't yet got network time.

Last few lines show that camera was rebooted and that's what I did just for fun.

..and just to clarify... ip 192.168.86.14 is right ip for this camera.
