your 8950 should have the latest wireless mini card already installed in M.2 slot of motherboard.  not sure whether your own wireless card will perform better than that.  for connection to router far away from pc around corners on different floor, try the 2.4 ghz band which is less susceptible to corner signal loss and also consider a Wi Fi booster.

The following table lists the Wireless Local Area Network (WLAN) module specifications of your XPS 8950.

You should be able to install a Wireless NIC PCIe Addin card (with rabbit-ears out the back). 

First, disable or remove the XPS-8950's on-board one.

If you instead try to Frankenstein-up a solution ... remember that the antennas need to be matched to the radios and frequencies in the NIC card.

Finally, your best-bet would be to just go ahead and run an actual (CAT-6 or CAT-7) ethernet cable to the downstairs room.

For reference, My 8950 gets about 450 Mb/s on my gigabit wireless network with my nearest access point 3 rooms away. I have a Dell notebook computer in the same room as the 8950 and it gets about 350 Mb/s on the same network.

In short, I don't know if you will get much better performance unless you get a WiFi card with a really large external antenna.

Translation:

The best way is cabling! Or install Access Point closer to XPS. It's just my suggestion! Good luck!

Thanks @edupferreira for the post. Yes, I agree. 

I say save the WiFi for the portable devices (like phones, tablets, and laptops).

Thanks for the report.

Nothing against using WiFi (when appropriate), but Gigabit Ethernet is 2 times faster, more reliable, more secure, and has no wireless processing over-head.

With a Desktop Gigabit Ethernet Switch at the end-point,  it can serve all the machines in that room.

Personally, I don't think WiFi was ever meant to be an "easy switch".

No worries, all the machines in my office are in fact wired to ethernet at 1 Gb/s. I was merely running a test on the WiFi card in my 8950 to give the OP a reference. I agree that wired is the way to go whenever possible.
