How do I switch from 5G to 2.4

If you want to provide feedback for apple. please see this form Product Feedback - Apple

In the meantime you might be able to set your router that it only emits a 2.4 ghz signal, I have that because I have a bunch of devices that does not support 5ghz

I have a Macbook Air M1, and I guess I am far enough from the router... That the machine keeps switching from 2.4/5Ghz in WIFI. As it keeps asking for a wifi password everytime 5G becomes unstable. Another fix, that usually works is just turn the wifi on and off. Sometimes that helps, but it becomes unstable you have to keep doing it.

It's really weird, because my android pixel phone does NOT have this issue and it is next to the computer in the same room / distance away from the router. Go google!!! YAY!

So, to solve this issue, I turned on the wifi hotspot on my phone. And I use the MAC to connect to the hotspot. Otherwise, it may work for about 15 or so minutes, then the connection becomes unstable. I get over 200 Megabits off the hotspot, But, when the machine is close to the router I get over 500. So, I guess this will be temporary, until I can get a ethernet cable punched into the back bedroom to install another wifi router.

It really would be nice for apple to make the machine connect to the stronger 2.4 signal and not automatically switch over to 5G. Since 2.4 signal is slower, but the range is much better. Apple should fix this in the next update.

What I would try is this:

Create two network connections in Network Preferences, one for the 2.4GHz and one for the 5GZ connection. Place the 5GZ connection above the 2.4GHz network in the list of networks. Then the connection will default to the 5GHz network. If the 5GHz network is not available the connection will automatically drop to the 2.4GHz network. If you want the default connection to be the 2.4GHz network just change the order of the networks in the preferences list.

5G generally means a cellphone communications protocol. Macs do not have cell capability.

I assume you mean 5 mHz and 2.4 mHz as supplied by a router. And not all routers may have 5 mHZ; you'll have to open the router and look. Or check the literature that came with the device.

I think the OP is asking about WiFi:

• The 2.4 GHz band provides the most coverage but transmits data at slower speeds.
• The 5 GHz band provides less coverage but transmits data at faster speeds.

What is "5 mHz and 2.4 mHz as supplied by a router"?

With respect to "cellphone communications protocol" 5G refers to "Fifth Generation" and has nothing to do with speed.

Sorry if I misunderstood your post.

"I think the OP is asking about WiFi:"

Yep, and that means his router: "The options are in your router". That why I delineated 5G Cellular from 5mHZ wi-fi.
