I have a new FRITZ! Box and look at the overview of the connected devices thrown. Currently there are a notebook and three smartphones.
I noticed that the notebook and two of the three smartphones have a band of 2.4 GHz and one of the smartphones has 5 GHz. It seems the device / system automatically determines what is used. However, in some cases it makes sense to change the whole thing from 2.4 to 5 or from 5 to 2.4 GHz (if that's even possible, but I mean to have heard something like that) and what does that mean?
Some devices do not support 5 GHz, the standard is newer.
In short: 5 GHz is faster but does not go as far as 2.4.
I have given the 5GHz WLAN a different name and can log in as needed on one or the other.
If your phone / tablet supports 5GHz, you should try this. It is at least twice as fast in my download. But it may be that the range is lower.
Recommendation: buy the 1750E repeater from Fritz (about 60 EUR) and install as a WLAN bridge in the house, if the range is too low.
With me in 2,4ghz 50mbit and in 5ghz 250th
A dual-band WLAN with SSIDs of the same name offers 2 WLAN networks (2.4 + 5 GHz) at the same time (the smartphone shows only 1 SSID but there are 2 SSIDs) Basically, the terminal first decides which network it uses. Often the devices change (due to sophisticated logarithms of the manufacturer) only the access point, if the current connection gets worse. It would be stupid to risk a change in a sufficiently good connection.
Conclusion: So it is device-dependent, when will be changed!
In addition, in the WLAN protocol "protocol extensions" (802.11r and 802.11v) via this protocol extension r + v, the WLAN client can be made to perform the change by the access point. A change is always a bit tricky, it can cause short dropouts, interfering with streaming.
Here's more to read about how a wireless router handles it:
PS:
And here are all WLAN protocol features and protocol extensions in an understandable short version:

YES, the 5 GHz ac standard is 3 times faster than the n standard at 2.4 GHz.
Gosh. I have 48/97
