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.
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?
