Trouble connecting to Ring Network

Hello all, I am hoping someone out there can help me before i throw my camera in the bin. We recently upgraded our wifi, and ever since i have not been able to connect my camera. I have followed the steps and each time i get to the stage of connecting to the Ring Network, and it tells me "connection failed" - i have tried on multiple devices ( Apple and Android) - i have disabled the 5G network on my wifi - i have fully charged the battery - i have reset the router - i have disconnected my phones wifi and reconnected I am at a loss and reslly hope someone out there can help! Thanks
