Got a Robovac G30 yesterday and ran into some difficulty connecting it to my Wi-Fi. I know the G30 only supports 2.4Ghz but that should not be an issue with my dual-band router. Really the difficulty was with my mobile phone (Samsung). It does not have a Wi-Fi band priority setting. I know there are some apps out there that can provide that capability. Didn’t want to pay for something that should be built-in to the phone.
What I did to correct this issue was to enable MAC filtering and added my Galaxy S22 Ultra to the deny list of my 5Ghz band. Problem solved!
