Hi
radio0

vs
radio1
Generic 802.11bgn
Channel: 11 (2.462 GHz) | Bitrate: ? Mbit/s
can I delete radio1? They have different GHz, what does that mean?

5.4 GHz and 2.4 GHz, respectively. Simple.

5.180 GHz
Naftali:

Ummmmmm...
Spectral bands are regions of a given spectrum, having a specific range of wavelengths or frequencies. Most often, it refers to electromagnetic bands, regions of the electromagnetic spectrum.
More generally, spectral bands may also be defined in the spectra of other types of signals, e.g., noise spectrum.
A frequency band is an interval in the frequency domain, limited by a lower frequency and an upper frequency. For example, it may refer to a radio band, such as wireless communication standard...
Some devices work on 2.4, some work on 5.4...some devices can access both bands.

which devices work only on 2.4? Is this some legacy standard?
All devices I connected to 5.4...
!?!?!?
Are you serious or joking.
Again:
Then this mean you know what is is, correct?
I'd suggest to leave it alone until you understand radios more. Disable if you honestly have no 2.4 devices that need to connect and it keeps bothering you.
Most modern wireless routers have radios for use with both bands.
Don't delete it. Some devices like 2.4Ghz while others like to speak on 5GHz.
2.4Ghz goes best through walls, but 5Ghz will usually give you better speed.

No. It's by chance. Which has more performance?
I guess you're confusing 5G of wifi & 5G of cellphone. Are you worried that using 5G wifi will cost your money ?

I not use a SIM card in router. So no

If a device can use both, usually the 5.4 GHz radio is better
If a device only has 5.4 GHz radio, no choice , you use the 5.4 GHz radio
But if a device only has a 2.4 radio there is no choice , you have to use 2.4...
I really think you're misunderstanding here...
Not only that, but even dual-band devices that use both 2.4Ghz and 5Ghz will drop to the 2.4Ghz band the farther away you get from the device, since 2.4Ghz has a much better range and less of a chance of being blocked by items between you and the base-station (at the expense of bandwidth speed).
If you aren't really using it, then just Disable the WiFi entry for 2.4Ghz, don't delete the radio itself. You never know when you might need it (most IoT devices are 2.4Ghz, for example, as are older devices)
