Tags: #Device Connectivity #DHCP bug
Model: Tapo C320WS  
Hardware Version: V2
Firmware Version: 1.1.15 build 240605 rel 49436n

when I choose advanced settings >> network settings and deactivate the static IP choice there and click save, the camera after reboot stays always with static IP enable if I have choose in my rooter static IP lease. The problem is that it assigns static IP on the camera level and not on router level so in case of IP conflict the camera is not accessible. The correct behaviour would be to remember and respect the user choice of no static IP at the camera level. The camera should then request an IP from the DHCP server of the local network and if the user wants a static lease at the router level so it be.

 

This persistence with static IP on the camera level sometimes but not always remain or changed erattically even without reboot. So I chose NOT static IP on advanced settings >> network settings and after a while (from minutes to hours) I found again the toggle button enabled for static IP.

 

Someone has to seriously review the code there guys 😕

Hi,
Do you mean the operation to disable the Static IP feature does not work properly on the Tapo C320WS? If so, please confirm:
1. The model number of your router. Have you enabled the feature such as address reservation on the router?
2. Is the camera connected to a NVR/PC/NAS via RTSP/ONVIF?
3. Ensure the Tapo app is up to date.
Best Regards

Yes this is what i am saying, the disabling feature in static IP in c320ws is not working as it should. Router Mikrotik RB 5009, yes i have enable the address reservation in my router and when i disable the static IP in my cameras it is working well but after a while the camera static IP enables again. Yes it is connected to a NVR via ONVIF It is uptodate.

Hi,
Is the static IP address feature enabled automatically on the Tapo app after something happens? For example, reboot the camera, reboot the router, etc.

Or the static IP address feature will be enabled randomly after disabling it.
Best Regards

Both, after reboot of the camera and randomly even you will not reboot the camera - after some minutes to hours it is happening by itself. After 1-2 days its almost sure it is enabled again (static ip in the camera level).

They have reached out to me. 1. They requested to describe the problem from the beginning. I am wondering if you have sent them the description. 2. They have requested a video of the problem and a log file from the SD card of my cameras - really? Guys, you have to understand that we are not being paid for finding and solving YOUR ERRORS. It is your job to try to replicate the problem and IF YOU CANT then you can ask the client to spent time and effort to help with this bug. For this bug, just follow my instructions and it is 100% reproducible. Just do your job and REVIEW the CODE. It is a bug in the CODE.

Hi,
1. Yes, I have sent them the link to this thread for reference, they may want to learn more about the usage scenario and network environment when the problem occurs.

 

2. Generally, we will try to reproduce the problem, but due to the various of customer usage scenarios and network environments, we may not be able to reproduce the problem successfully. Therefore, your cooperation is appreciated in providing the log when the problem occurs in a specific scenario for further analysis. You can inform the tech team of your situation by email, and they will continue to help you handle the case.

 

Best Regards

Hi,

I have 2 C320WS affected by the same problem. I configured out of the box to get dynamically an IP (my router's dhcp assign them a fixed IP).

Never watched this setting in the app, but they always showed issues in the router config page. Despite the router couldn't detect them, as if they were powered off, the cams worked perfectly, so I didn't think of resolving the issue.

I then found this post on the forum and went into the app and found that the cams had fixed ip configured with the parameters they took from router's DHCP only on the first configuration. I disabled this setting on both, the router finally detected them. After a couple hours the fixed ip setting is on again.

So this is definitely a bug. both the cam are on firmware v.1.1.15 that is the newest.

Please fix it soon

Hi,
Is the camera connected to a third-party app via RTSP/Onvif connection?
If so, can you disconnect the RTSP/Onvif connection and then check if you can disable the Static IP option successfully on the Tapo app? If the problem remains, factory reset and reconfigure the camera for a try.
Best Regards

Mikrotik RB5009 with DHCP server on it

Mikrotik cAPax connected to the RB5009 to which the cameras are connected to via wifi

Other TP-LINK cameras (2x C210, 1x C110, 1x C310) connected the same way have no issues

The issue happened even when I used 3x Deco M4 connected to the RB5009 instead of the cAPax

 

the two C320WS ar the only devices out of 30 doing this

 

I already factory reset twice one of them. Same issue

 

clearly there is no third part device interacting with the cameras that would be able to force the firmware to enable again something has been disable using the only way possible to disable it (the app). If it could be possibile, well you have a big security issue to solve first.

 

Open the code and fix it please
