As the previous post about version 1.7.0 was too long to navigate for information on the newly released 1.8.x versions, I have created this new post. Kindly share your feedback on how the new 1.8.x work. Your input will greatly benefit other users.
Thank you very much.

@ARGamingPK1 this is a false 😃 the version of 1.8.2 has too many bugs in it 😆 like Gateway handshaking, client finding to connect as Luci failed in critical condition 😲 Guest network errors even it is turned off 😆that means ffirmware forces deco to find them, IPTV VLAN and VPN errors in critital with an alert even if is not set up 😨 Now Deco is mad of maintaining blllshit firmware's instructions 😫

@DanielKir You can update to 1.8.2 which is much better than 1.8.1 in overall performance.

After some time, I’m coming back here to once again question the terrible update that was released for the M4.
It’s surreal! After version 1.8.0, my router has never worked as it should again! With every version released, it seems to get worse. The developers must be amateurs or you don’t have an efficient testing pipeline, because it’s not possible to release firmware with so many problems.
I updated to version 1.8.2 and devices connected to the network constantly lose connection. I’m in the middle of a call, the internet fluctuates on the PC, but works on the cellphone.
I can’t understand how you still haven’t been able to solve this after so much user feedback.
What’s most irritating is not being able to downgrade to a version prior to 1.8.0.
Do the users, and yourselves, a favor, enable downgrade to the last version before 1.8.0, go back to the development table, fix all the problems, run proper tests, and only then release it to the public.
Sorry, but unfortunately there’s no way not to be angry about a situation like this. 😤📡

I believe the issue is related to DNS or to some configuration associated with it.
After manually configuring the DNS on my computer, the dropouts, curiously enough, stopped. On mobile devices, the issue does not occur, since I use AdGuard DNS for ad blocking.
On the router, Cloudflare and Google DNS servers have been configured from the start.
I am unable to precisely identify the root cause of the instability, but, so far, this change has apparently resolved the issue.

The problem really is with the firmware. I accessed the router through the web interface and exported the error logs.
If you look closely, you will see that DHCP is restarting on its own, redistributing IPs and reassociating the connected devices:
udhcpd[1900]: Received SIGTERM
udhcpd (v1.22.1) started
clear ip c0a84467
Sending ACK to 192.168.68.103
Sending OFFER of 192.168.68.250
client_action:disassociate
client_action:associate
Clearly, this latest firmware version is disastrous. 😤.
I attached the complete log for review.
