I purchased 3 Tapo cameras during one week (a set of C420 and a C520ws). I'm testing the C520ws inside ma house, C420 are already working for one week.During the set up process of C520ws the internet connection in my house has crashed twice (even disabling the modem). I'm connecting to a TP-Link router. The router is doing a good job for several years, has never ever generated any issue like this. The internet connection till the modem is healthy, the service provider detected the router failure. Unplugging the camera did not help, neither switching off or resetting of the router, I had to reach the router quick setup and go through all the steps. I faced the similar issue the next day.Can you pleaser advice what the cause of this can be? Thanks in advance
