2.4GHz and 5GHz SSID name - the same or different names for the frequencies?

I have a question, if a router, e.g. Netgear R7000 supports 2.4GHz and 5GHz, then I should set their SSID and password the same for both frequencies, e.g. "NETWORK" and expect that, for example, the MacBook will choose the best frequency for itself at the moment, or also the SSID should be different for both of these frequencies? e.g.:
ssid: "2.4GHz NETWORK" for 2.4GHz
ssid: "5GHz NETWORK" for 5GHz
?

On the fritzbox 7390 router for 2.4 and 5 GHz networks, the names are the same by default (FRITZ! Box Fon WLAN 7390).
Conclusion - yes, set the same name.

I'm not so sure. For this to work well with the same name, the router must support the ability to quickly switch between, or whatever, different networks. And the fritzbox can support something like that, and other hardware doesn't have to! And then the effect will be such that you will move a few meters and the WiFi on the device will disconnect, because another network will have a better signal in this place.

If both cards have different MACs and they certainly have, the name may be the same, for devices that connect, the SSID name does not contribute anything, it is the user layer.

The problem will only be for the user because he will not know which network is 2.4 which 5, of course, in such windows XP after hovering the cursor and stopping it on the network name, information will be displayed, but it does not make sense.

So, to sum up :
- for the action itself, it does not matter
-may be annoying situations depending on the software
-may happen like m.jastrzebski wrote, wagging networks back and forth, but first you need to notify windows about network passwords, the same names will not cause switching, if someone adds one as the default, everything will work (this will happen in in total, it counts as the second point, the persistence of the software) but _ it will not break itself_.

ost wireless stacks do not consider these networks to be different to each other, so 2.4GHz has the same weighting as 5GHz.

If this isn't important to you, then keeping the SSIDs the same will mean it will pick whichever it sees first.

If you keep the SSIDs different, it means that you can prioritise 5GHz over 2.4GHz by adding both to your Wi-Fi connections, and saying that one is better than the other.

Note that 5GHz is not inherently faster than 2.4GHz. They both have the same theoretical maximums, 150 megabits per second (single radio chain), 300 megabits per second (two radio chains and two spacial streams), or 450 megabits per second (three radio chains and three spacial streams). However because the 5GHz frequency band is less crowded, there is more chance that the AP can get a full 40MHz band of radio to carry data.

It follows as much as is already written.

Exactly, I have a feeling that I had the problems that you wrote about.

It happened that the phone or laptop lost its range when moving from room to room with the same SSID and passwords for 2.4GHz and 5GHz networks

I will now run tests with other SSIDs

The names of the networks alone will not cause this, I know that everyone wants to check how it works, but at this point the phone remembers and then he wags, just click forget (in android) in windows, it works similarly
If you set up 5 routers, gave them different names and passwords (but remembered them on the phone), walking around the house, he would also change
-BECOMES
-BO connects with the strongest of those he REMEMBER.

This is a user error .... I would say not the problem itself.

How to do it in the most optimal way to make the connection as fast as possible?
Make 5GHz your priority network?

It depends on the equipment used, the priority will be what you set on the equipment, and the equipment varies, one will go anyway and another will not, and still another will only have 2.4.

There is no prescription here.
I will not mention the noise because it depends ... on the specific situation.

There is no AC mode in almost any equipment yet.
70% of the equipment will not even fly on N-ce
So the discussion of performance feels a bit like a shrimp for a Monday breakfast.
