MS Windows 10, latest update on a laptop with core i7 10th gen CPU.What operating system are you running on your laptop?
I also did a network reset via Settings/Network/Status but all that did was screw up my WIFI link between my laptop and the mobile broadband modem.
(Although I don't need/want the modem in order to use the NVR I'm now busy trying to sort that out. I can connect to my mobile phone hotspot via WIFI but not to the modem. I am able to use the modem by plugging in the ethernet cable between my laptop and the modem.)
