Unexpected disconnection occurred (every 5-10 minutes)

Title say it all. I have extreme 'unexpected DC' problem since launch. I play 5-10 minutes then I experience insane rubberbanding (5-10 seconds freezes). Here's the steps I tried to fix it without any effect :

- Tried DX11, vulkan and DX12, didn't worked.
- Tried a LOT of different graphic options, lowest to highest, didn't worked.
- Tried to use 1 core from my 7800X3D cpu, didn't worked.
- Updated, restarted my modem and router, didn't worked.
- Tried ALL servers, didn't worked.
- Updated my GPU drivers, didn't worked.
- Tried a VPN, didn't worked.
- Tried using my iPhone wireless network, didn't worked.
- Verified files on Steam, didn't worked.
- Stopped my Bitdefender antivirus, didn't worked.

I have 0 problem with any other games on my PC or Xbox Series X or PS5 Pro, the only problem is with POE2 :(

I played for 1h30 between 00h30 and 02h00 AM today without any problem, but this morning and this afternoon it's totally unplayable.

My setup :

- CPU : AMD 7800X3D
- GPU : 4090
- RAM : 32 Gb of DDR5
- SSD : everything is on NVME

If anybody have any idea, that would be greatly appreciated because I really love the game but for now it's impossible to play.

Here's a quick video of the problem, it's like that 80% of the time :(

Thank you for the help :)

Video for my problem, the only thing I notice is that I have more problems when the servers are highly populated (AKA 8-9 PM on NA EST). I don't have a lot of problem in the morning.

Alright everybody so I found the problem on my side. It was the 5ghz router. I tried 2,4ghz earlier today and I had WAY LESS problem (more stable connection) but I just installed a 75 feets ethernet cable to my PC and... 8 ms network stable, no issue now. For me, not using the 5ghz router and going to ethernet fixed the issue.
