Tapo C520WS keeps disconnecting from wifi
Tapo C520WS keeps disconnecting from wifi
Hi TP-link support ,
I am currently using a Tapo C520WS it worked well for 5 days after installation but now it randomly disconnects (mostly while viewing the live stream) and is not viewable even in local network until I reset the power manually and the video is very stuttery in the rare time it works.
The camera freezes and disconnects from the router and the status led turns yellow
But local recordings and motion tracking still works
It's highly unreliable and defeats the purpose of a security camera
Some stats :
WiFi range: -64 RSSI (router placed within 8 metres of the camera)
RTSP/Camera Account : Turned Off
Network Settings: Turned Off
Video Quality: 720p 15FPS
Router: Nokia G2425G-A (provided by airtel)
The diagnostic Logs reveals this before the disconnection
[Transmit]buffer full! iov_size(1659) try_send(1659) sent(752) left(907)
idle --> dns query.
[Transmit]buffer full! iov_size(65388) try_send(65388) sent(41594) left(23794)

<4>2025-06-14 13:48:23[HTTP]http client(local-0) send buffer is full!
Further followed by:
DNS failed, error_type: 1006.
I have tried setting 8.8.8.8 and 1.1.1.1 in the DNS of my router and in the camera also
I tried factory resetting the camera too and is of no use
Other devices in my home network works fine except the camera
I use only the 2.4 Ghz band for the camera and it's a single router system
I have even tried using a mobile hotspot and it has the same results
I use the original adapter
Please find a solution to this problem at the earliest or replace/return the camera if found faulty.

Hi,
The Tapo C520WS V1, v1.3.2, has no known bugs related to the Wi-Fi disconnection issue. There are new features and optimized algorithms added to the new firmware v1.3.3, and they improve the product's use experience and stability.
You can press the reset button on the camera for 10 seconds to factory reset it, reconfigure it to make it work, and then update to the v1.3.3 firmware to see if it improves the disconnection problem.
If the problem persists, please confirm the following information:
1. Is your camera connected directly to the router's Wi-Fi? What is the signal strength(RSSI value on the camera's Device Info page)?
2. When the disconnection issue occurs, is the LED solid amber on the camera? Can other devices connected to the same router successfully ping the camera's IP address?
3. How frequently does the disconnection issue happen?
4. Please refer to the instructions below to collect the camera log for further analysis.

@Joseph_ Did you get a replacement for the defective product?

Hi,
I managed to contact local support and they accepted the unit for a replacement but they told they will still replace it with a V1 unit.
If V1 is faulty why not replace it with a improved V2 unit with good connectivity.
If so what are the changes between V1 and V2

Hi,
1. Usually, you can go to our official website, search for Tapo C520WS, go to its Overview page, select V1, go to its Specifications page, repeat the steps, select V2, go to its Specifications page, and check their differences.
2. Your camera's disconnection problem may be a problem with the specific camera, not the Tapo C520WS V1. TP-Link generally provides corresponding replacements based on the model and version of the product you purchased. If you have further RMA requests, it is recommended that you contact the local team for discussion.
Best Regards

I’m having the exact same issue with my C520WS. It worked fine for the past 2.5 years, but after updating the firmware to version 1.3.2, the camera started going offline. I tried every suggestion and solution from Tapo support and the internet, but nothing worked, until one day I disabled auto tracking. After turning it off, the camera stayed online. When I turned auto tracking back on, it started going offline again. You might want to try disabling auto tracking on your camera to see if you can reproduce the issue.
