Orbi RBR750 Link Rate

Greetings,

I have an Orbi RBR750 with 2 satelites. The connection between them as well as all of my wifi devices are good. The problem I am having is the link rate for all of my wifi devices. I have 6 wifi security cameras, 2 iPhones, 2 laptops, a streaming device and a couple of smart light bulbs. I noticed in the Orbi app that the best link rate I have is 72Mbps. To me that seems extremely low and I have not been able to locate any good info on why this may be or if there are any solutions. Maybe this is normal.

Anyone have any experience with this subject?

Thanks
