If anyone is having issues and uses a Pixel, try using any other device to set up the S7 then once set up, you can go back and manage it via your Pixel.
You were very lucky, I have tried for one hour and it won't connect. And seems I am not alone, many users have this issue, so I'm very disappointed in roborock
I disabled 5GHZ on my router ....still a nightmare. Even tried to connect to a guest wifi ... did not work. ... tried Phone Hotspot (setup via iPad), did not work. @@MrMisuma Did you get it connected`?
