2,4 / 5Ghz Wi-fi Time Capsule

Do not name the 5ghz .. It is not necessary to name it.

Here I use it named.. and it is ticked.. that means i have two different SSID.. which by the way is the best way (IMHO) to run things. I will explain why below.

If you do not wish to have a separate name.. Do not check this.

So you have the main wireless page filled like this.

Use a short wireless name.. eg TCwifi (no spaces and pure alphanumerics).

The 5ghz will be active and clients will join 5ghz or 2.4ghz depending on signal level.

Here is the catch.

Only 5ghz provides high speed wireless.. 2.4ghz in apple systems can go no faster than 217Mbps link speed on a good day.. mostly 130Mbps.

The client will connect to the best signal.. If you move one room away from the TC.. the signal from 5ghz will fall dramatically but will still work faster than 2.4ghz.. usually much faster.. but the client will use 2.4ghz because it links to best signal.. NEVER best speed.

This is My Opinion and others around here strongly believe in Apple doing its automagical voodoo stuff.. and that works for most people albeit slowly.
