Because all my is high so I have 2 c520ws & C425ws and c420s without any issues connecting to wifi but this c530ws make me so mad so I cannot use yet, if I use If something is happening I need it to remove to connect it to the cable on my router:(((

  @Martina1935 I tried many ways only if I plug in Ethernet cable is worked for me, then I choose wifi! But if I have my camera up somewhere higher so what I am going do removed it the camera come inside the house to plug in? Tapo needs fixing this issues soon is possible or giving us a beta testers to helping the team! Now my camera is in the box I cannot use it yet! 

Hi! I had the same issue with a new Tapo C520WS device. I have an ASUS RT-AC65P router. This can manage more SSIDs than one, i have a seperate network for smar devices. The SSID contains underscore characters "_". During the setup of this camera it was not able to find any of my 2.4Ghz networks, nor the main one neither the guest network.

I tried to rescan more times, i resetted the camera but it did not help. The camera was recognized more networks from the neighbours but not mine... it's crazy....

I tried to setup a new guest network without underscores. It did not help at all.

Finally i connected the camera via cable (ethernet) and i finished the setup successfully. During the setup i was asked about the wireless use, i confirmed the connection with exactly the same SSID and password and it was connected! 

Now i am updating the firmware than i'll try to remove the wired connection and use it wireless. I'm not sure maybe with new firmware it could be setup properly.

Let's see...

  @GaborHungary Ok so finally i unplugged the LAN but i had to reset the camera because it was not working without ethernet connection. I resetted the camera, the firmware was kept at 1.1.1. I started over the initialization but it did not recognize my wifi networks AGAIN! WTF!

Ok, i choosed V1 connection, i set ip up with hotspot wifi connection and when i was asked about the wifi i've set it up properly. The camera said loudly: "wifi connected". Ok i was than surprised. I started to use the camera with wired connection and wifi too, it was quite fast.

Than i unlpugged the LAN and surprisingly it was working on WIFI! Okay, it was reacting very slow on the controll commands like directions. But it was at least working.

I don't get it... I've bought 4 smar plugs too in the same time with camera. All of the smart plugs were able to connect without ANY issues! I've finished the connection and firmware updrading of 4 plugs in 15 minutes. But this camera....My chinese tuya compatible camera (half price like this) is working from long time wihout problems.

For me, changing the router's 2.4G Wi-Fi channel to 6 worked. It was able to detect the network after that. 

  @Allen8777 this was very useful. I also had similar problem and by changing WLAN setup from b/g/n auto to g/n helped and 520ws connected smoothly. Thanks for your support. Don't know why this is not getting fixed till today

Thank you, this worked for me on my Fritzbox 7490 and Tapo C52A. I switched from 802.11 g+n to 802.11 b+g+n. All the sudden, the new configuration finally found my own Wifi and I was able to set up the camera wirelessly. Perfect, thanks so much!
