Brand new Aurora R4, Wifi slow

Hello

I received my computer yesterday and all my attempt to fix the problem failed so maybe you guys can help me.

After doing the first login setup I did the updates and everything but noticed how slow my internet was so I ran a speedtest and the results were horrible, 1-1.5Mbps downloading speed.. Upload seems fine at 3 Mbps. I ran the same test on my old computer and I get around 20 Mbps.

I though maybe the drivers of the Wireless Adapter need to be updated, so I downloaded the drivers on dells website right here:

Now before I even finish downloading the file I get a bluescreen saying APC_index_mismatch yadada. I reboot the computer google the error apparently It might be the drivers, good.. I finish downloading the drivers...remove the previous ones and install the new one.. same issue. Now I tried a few times and I got a little upset so I reinstalled Windows thinking It might do the trick. Nope, I reinstalled everything.. all the drivers.. I got a few bluescreens and very slow internet speed. The signal is at Excellent. 

I'm a little upset as I had many delays in my order and I get a computer that just doesn't work properly.... Anyway, I'll contact Support whenever I'm off work but If anybody got any ideas why and how I can fix that I would appreciate it! 

Thanks!
