Following are a few possible reasons why this may be occurring:
1. Check whether the antenna is tightened.
2. Set maximum transmission power: In some wireless routers, the transmission power can be reduced, which reduces the performance
of the wireless network. Make sure your wireless router has the maximum transmit power set.
3. WiFi channels: Check if WiFi channels are busy, and possibly reconfigure them to “Automatic.”
4. The camera IP address conflicts with other devices, needing to set the camera IP address to be a fixed one.
5. Change the name of the wireless network (SSID): If there are different wireless networks with the same name (SSID) in your environment because a neighbor uses the same wireless router, a wireless repeater has the same name as the router – WLAN devices could try to automatically connect to the wrong wireless network, Therefore, set up a unique wireless network name in your wireless router or repeater.
6. To check the Wi-Fi signal, normally, it should be more than 3 bars.
(The distance between the camera and the wifi router being too far might cause the wifi signal to be less than 3 bars ).
