Can't get wifi in my room, but only in linux in my new notebook.

Hello, recently I bought a Loq e 15iax9e with Windows (the Linux edition was out of stock) and as soon as I got it I went to install Linux, but I noticed that it wasn't connecting to the wifi. Long story short, in linux I getting wifi in every place of the house except my room, but I can get wifi while in my room with Windows, my cellphone and my old netbook (both in linux and windows). I think it's a Network Manager configuration issue but I have no idea how to fix it.

I'm using ubuntu 26.04 beta (so I now the problem is not the kernel version - 7.0 - or driver version) on a flash drive (I want to get it fixed before installing), my network adaptor is an intel wifi 6 ax203 and my router is a HI3120 (EMTA DOCSIS 3.1 from CLARO - I am from Brazil), which supports wifi 5 (in places where the signal is weaker it *seems like* it uses wifi 4).

Running "sudo apt update && sudo apt upgrade -y", disabling ipv6 or increasing mtu doesn't fix the problem.

If anyone got any idea, please I need ur help.
