Hello again,
So a few days ago I posted about a new computer with issues in wifi department, yesterday i returned it for another one of the same model, the exact same. Had no internet disconnection at all until a few minutes ago, it did the exact same thing the other did. WiFi cuts without warning, can't reconnect to it for a minute or so. I did everything I could, updated the drivers, beyond what Windows gave me (a version from July 2019, i installed a version from this January), I uninstalled Norton, I disabled powersaving mode, I made sure my channel wasn't full (I'm the only one in it). I rebooted the wifi card. I don't think my provider is to blame, my phone did not disconnect when the computer did.
Done pretty much everything, except opening it up, cause I don't have that kind of knowledge.
I'm not mad anymore, I'm just desperate, I saved money for over a year to buy this computer, and of course i like some gaming, but I also use this computer to work, I'm a student, working a Master's thesis, and Internet is quite an important part of that work.
I just want a functioning computer, if you guys have any tips, any advice, anything... please.
Good day, and I hope one of you can save me

PS : I'm sorry if the language is a bit clunky, English isn't my first language
