I had three DS-2CD2442FWD's (R6 Cube 4MP) and updated them from 5.4.x to 5.5.0 and it ruined one and made the other two unmanagable via WiFi. I spent hours trying all kinds of things around DHCP, Static IP, etc. Basically it really messed up the network settings. Yes, all the Hikvision tools can...
