Hi, i bought a new laptop couple weeks ago. the laptop as you can tell by the title is a dell inspiron 14 5000 series. It includes the driver is an Intel dual band wireless- AC 3160. The problem I have is that the internet is very slow. I am getting 1 mbps when i am in my room, but when i stand right beside the router i get my normal mbps which is 20 mbps. I have done some research on resolving this issue and the most common answers i have got is get a wired connection (if i am gonna do that, than i might as well get a pc) and get new driver (2x2). I have also changed my HT Mode to disabled which works, but the internet connection is still really bad (5 mbps). Now my action is to get a new driver but just to be sure is there any way to fix my internet connection? 

I know its not the internet since the internet on the other laptops work perfectly fine. And i would return the laptop but unfortunately my 2 weeks are up.
