Glad to hear that it's working better for you and thanks for keeping us posted on your latest results!
I got another wifi drop. And then checked DHCP leases on router's side. It was showing Expires After: 23:59:xx for my laptop. I set the lease time to 24 hours before. So, yes, the drop happens after lease time expires. So, for me either I have to increase lease time for longer period to reduce the frequency of the problem or contact Apple support again.
I'll also try to set it to 8 hours (as this is exactly what apple recommends), if it will happen again (I think so) I'll contact Apple support to check for options they have.

Ok, actually info from my previous comment about DHCP lease time doesn't make sense, because it resets after reconnect, so after reconnect it will be 24 hours (or like set in settings) every time.
Another thing - I had another call with apple support and looks like the only way is to bring laptop to official service and then they can leave it connected to wifi to check if the drop happens for them too. If yes, then they will replace the laptop or fix it for me. I think I'll give it to service but only in September.

I hope you've changed the default SSIDs, and the admin username and password, because you just posted them on the internet, FYI.
Wifi passwords are very easy to hack if you know how. Just FYI.@xraydoc yes, I changed it right after first connection to the router. But actually I don't mind if somebody connects to my router because they need at least wifi password or arrive to my house to connect ethernet cable, I'll not let them go inside
Btw, I had wireless logging enabled in the Mikrotik router.
And I got another wifi drop few minutes ago. In logs I see
"extensive data loss"
which described here:
wiki.mikrotik.com
like this: local interface decided to drop connection to remote device because of inability to send data to remote after multiple failures at lowest possible rate. Possible causes - too weak signal, remote device turned off, strong interference, some other RF related issue that makes communication impossible.
So, it matches behavior I see from laptop, many wifi networks disappear and only few that is close to laptop (like printer's wifi) still visible. Somehow strength of macbook's wifi goes down for some time.

If a lot of devices are losing the 5G signal it sounds more like interference.Btw, I had wireless logging enabled in the Mikrotik router.

There is a WiFi diagnostics mode, though I don't remember how to activate it from memory.
No, only one does - Macbook Pro 14. I have 2 iphones, 2 ipads, 1 raspberry pi, and printer connected to this wifi.
Ah. To get the diag mode you have to option+click the WiFi icon in the menu bar and it shows up there. Maybe the OS can tell you why it is losing only the 5Ghz signal when it comes time to renew the IP address.
One more update. I was working on laptop in another house today in 300m from my house. Was connected to another wifi router. And again wifi dropped one time. So, I don't think this is some special issue with interference, as from old house I took only my iPhone and this Macbook pro 14".

Actually I used the diagnostics and it didn't tell anything wrong with my connection. But there is some mode when it waits for wifi drop and then save the report and I actually catch that moment with that tool and sent report to Apple with Feedback Assistant on 11 of June. There is more than 300 files and it it's useless if you don't know what to check. No response from Apple since then.
Just for info, after my last post I set expiration to 900 days in router's config for MAC Address of my laptop. Since then I didn't have the drops. So, looks like this is working solution. If nothing helps it makes sense to try to make sure there is no DHCP lease expiration or it set to months or years. So, for now I'll stick with this solution.
IMPORTANT NOTE: DHCP lease expiration time and Static IP based on Mac Address are not the same things. May be some routers remove expiration time when you set static IP, but in my case after I set static IP it was still renewing DHCP lease. So, I had to change lease expiration time too.

I'm having exactly the same problem. And I also tried many ways from changing Router, removing metal objects near Mac but it still happens. Everything seems to end when I'm not at home.
Because most of my routers use Broadcom CPUs, I haven't tested with Qualcomm CPU routers yet. But it seems that in cafes or shopping centers where I use Wifi, there is no problem of wifi drop.
I will try adjusting the DHCP Lease time like you and see how it happend. I'm also in Vietnam.

Okay so from what I understand all of these cases got 1 thing common which we are all from Vietnam.
Please try to increase DHCP lease + and verify that your wifi country code is set to VN too, after I rarely get wifi drop (I said rarely because there a few time when I lost wifi for 1s and got back again)
Also only happen to my 5ghz and NOT 2.4ghz
Btw, same for me, I still get the drop sometimes, but may be twice a week or even just once and usually it happens when I leave laptop idle and then arrive to continue using it. And also in this case I can reconnect manually and it connects right away. Before I had to wait 1-5 min before I can connect again.
I still get Wifi Drop even after increasing the DHCP Lease time to 30 days (I'm using Mikrotik Router as my main Router with Deco M4 and ASUS AX55 in network). And it usually happens when I'm using the device, because I plug it in all the time with the monitors. Here's some info on what I'm plugged in and using:
- 1 USB Type C Hub from Baseus that I use to plug Ethernet and HDMI into a Dell Full HD monitor. Previously, I only used Hub Type C to HDMI and still had problems, so I changed to another Hub, which is Baseus.
- 1 USB Type C to Displayport cable to LG 2K Monitor.
- 2 Bluetooth devices: MX Master 3 and MX Keys.
At the coffee shop when I don't see Wifi Drop, I just connect to MX Master 3. I am suspecting that Bluetooth is also a cause of Wifi interference. Because there was one time I typed very quickly and a lot on MX Keys, Wifi Drop happened continuously for about 5-10 minutes.
It seems that this Macbook is very sensitive to 2.4GHz channel because around me a lot of devices use Bluetooth and 2.4GHz channel. I'm still using the 5GHz Wifi channel instead of the 2.4GHz.
I used App Wifi Explorer 3 and found that some Wifi on 2.4GHz channel lost connection on the graph randomly. Including my 2.4GHz Wifi.
Hopefully Apple can come up with some solution to this situation because Apple Support they also want me to go to the service center because they don't understand what I'm having problems with.
Hello everyone.
I'm also living in Vietnam and also have MBP M1 Pro 14' and also have exactly same WiFi problems.
At home I'm using Huawei AX3 Pro router (5Gz network only) and only my macbook has problems with it. Oculus Quest 2 that is using 802.11ax does not have any issue. I did not have any problem with WiFi at the office until the network was not updated to 802.11ax. I tried everyting I could find in the internet but without any success. Does anyone was able to fix this annoying issue?
P.S. I have 3 MBP M1 Pro 16' around me at the office and none of them have any issue with WiFi

So for now the best solution is to set DHCP lease expiration on router side to big value like 1 year for Mac Address of your macbook.
Or if there is no ability to set lease expiration time only for certain machine, set 1 or 2 weeks for all clients. If this is home router, but not router in cafe where many new devices connect, it should not make any issues and same time will (almost) solve the problem.
Here are terminal commands.
