I just installed linux mint in my surface pro 3 for the first time. I did everything right. Updated every firmware, installed the linux surface kernel step by step.Everything worked just great even the first 2 days wi-fi worked completely fine. But from yesterday it is very slow no matter what i do. I disabled the wifi power saving option, disabled the IPV6 mode for my router on the device and set a fixed dns point too but it is still slow. And not only my device is slow, whenever I connect every other device connected to my router doesnt get any bandwidth as well. But I tried to connect internet on it through my phone's hotspot and it works perfectly everytime i do that.

I have almost done everything I can find in the internet regarding this matter.

How do I connect wifi but not get slowed down and drain all the bandwidth from every other device?

Surprisingly my sp3 still works. But the battery is no more and the touch screen is dead. I remember it being fixed by directly connecting the charger to the device when I took it to repair.

Now I run it using wireless keyboard and mouse.

It now struggles very much even running windows 10.

It has 4 gigs of ram, 128 gigs of storage and the processor is i5-4300U

What distro should I look for?

I dont have much experience with linux but I know the basics.

I need help choosing the best distro to get started on it.
