Ring doorbell 2 and TP link x20 mesh wifi

Hi I have installed a tplink x20 mesh system and my ring2 battery doorbell isn’t liking this setup, the only way I have managed to get it to connect is to have a guest network without any security key, as the device would time out the setup and it would just keep being sent back to the start of the setup process, now I don’t think having a wireless signal without a security key is ideal, this needs to be fixed!!
