So for a while now, the wifi on my T440s would constantly disconnect and when it is connected it's slow as hell compared to my phone. That's why I'm planning to upgrade my wifi card. I got a suggestion that I upgrade to an intel wifi 6 ax200, but all vendors say it doesn't support my laptop. I've seen that you can whitelist wifi cards in bios to be able to use ones that aren't supported by default by your laptop, but will this card work if I whitelist it? Any other suggestions on what I should do?
