D-Link AC1200 DIR-822 vs AC750 DIR-816. I found an AC750 at good will. AC Wifi is 5 years old??

3 questions! 1- What type of WiFi Analyser are you using? 2- What do you mean by checking the the "Crystal are still charged" and 3 - What is a Flux capacitor and how can you tell it is in good shape...
Thanks
