Orbi Router will not allow 2.5GHZ Blink device to connect

I have Amazon Blink cameras and have not been able to connect them to my Orbi RBR50.   The only way I have been able to get them to connect is directly via the modem.   Does anyone have any config suggestions so 2.5MHZ devices (which is what Blink runs on)  will connect.   I thought Orbi would automatically connect the device but so far not successful.   

Any help and suggestion is greatly appreciated.
