Hi my friend. I have X5C with husky air cameras (believe it's the same you have except it's 4 channels). I installed the first time in 2019 and now I had some grainy images and decided to reset them. Now the NVR doesn't detect the cameras no matter what I do. Since the cameras don't have security code, I cannot add them through the app. Tried different codes, the same as NVR and nothing. I know wifi is working because their networks appear. I was able to connect through wired connection but it can't configure the wireless connection, and it is lost when I disconnect the wire. Using 2.4 Ghz wifi only. Any idea if there is a conflict of IPs or some configuration that is not letting the NVR connect to the cameras?
