Make desktop wireless

Make desktop wireless.
I need some basic advice on how to best make a desktop computer work with wifi  It is a Dell OptiPlex 7020.  I assume that the network access for the computer will run faster by installing a wifi card inside the computer as opposed to a USB plug in adapter.  Is this correct?  The computer would be approximately within 20 to 25 feet of the 802.11ac router and the signal needs to work through walls.  I also need to know if the signal quality would be improved by buying a MIMO router.  My current router is Sagemcom brand router provided by the cable company of which I pay $5 a month for.  If I buy a router I am looking to invest in a Linksys brand one.

Also:
What brand of wireless wifi card is best.  A brand and part number would best answer this question.  Is their a review site that you can provide me with that lists reviews for 802.11ac wifi cards?

A wireless card bus connected will be better. I got mine from Lenovo for my Lenovo Computer. You need to look at your manufacturer website for accessories

Install WiFi Adapter and attach the antenna. Done.

The WiFi card must be suitable for your computer.

USB Wireless adapters are very common at your local electronics store. Here is a review list.

https://canada.bestreviews.guide/wireless-adapters

Get one that is compatible with your operating system and is at least N speed or preferably AC.  

Netgear and Cisco have very good wireless routers.

You should go to a shop and ask questions, then make your selection.

Not in my experience, no. I've struck scenarios where the opposite was true in fact. I've found USB Wifi adaptors work equally well to physically installed cards with antenna's, with actually less chance of interference from the mainboard and case electronics as they can be moved a short distance away from the case with a USB extension cable.

If you get an AC card, it will be just as fast as Ethernet, but Ethernet remains the fastest.

I have a Wireless Card in my own Desktop computer but I predominantly use Ethernet.

Still, as noted earlier, there are lots of USB Wireless cards you can use.

I need a review site that lists reviews for wifi for more wifi adapter cards and not just USB adapters.  Preferably ones that are MIMO.  Which is faster. usb 3.0 or a card that is connected to the motherboard?  I'd like get one that is MIMO and has 3 antennas.

Thank you

I think if I opt to move the computer I would like to buy something like this:

That looks pretty good from my read so it should work. I use a Cisco wireless router so almost any good wireless card works
