I have an older airport Extreme and 2 newer Time Capsules. Each of these is wired into an Ethernet Cable. I'm trying to get the best coverage I can and I don't think I'm doing it correctly. Each can do 2.4Ghz and 5Ghz and I believe the Time Capsules can also do 802.11ac. Anyway - I have each currently set to "Create a wireless network" currently. Historically I've named the 2.4 network "myNetwork" and the 5Ghz network be "myNetwork 5GHz". That doesn't seem right to me as on my device I have to sometimes manually choose one or the other to get the best signal. So I figured I'd go through them and I renamed the wireless network "newNetwork" in all the 2.4 fields as well as the 5Ghz field. I figure that's the way it's supposed to be and let the device figure out the best connect. But when I do that and go back into the 5Ghz section the checkmark goes away indicating it's in use. When I try to click it again it doesn't stick. Is this the right way to do it? Am i missing anything? Any advice would be appreciated. Thanks!!
