There are basically three ways to add wireless to a PC USB adapter, Ethernet WiFi adapter, and internal WiFi card.
Here are the top three option for installing wireless to a desktop PC.
3 Way to Add Wireless to a Desktop PC
- USB WiFi Adapter
- Ethernet-to-Wireless Adapter
- Internal PCI Wireless Card
There are many USB adapters available and depending on the unit bought are very low-cost items
Some are built for range with larger antennas and some are small almost hidden once plugged in.
Wireless 802.11 standards have evolved becoming faster over the years with new versions able to work in the 5Ghz band while older units only work in the 2.4GHz frequency.
Dual Band refers to an adapter that can work in both 2.4GHz and 5GHz frequencies and is usually the best option.
The wireless protocol also matters since new ones can transfer data faster.
Main WiFi Protocols
802.11G or Wireless-G – Speed up-to 54Mbps
802.11N or Wireless-N – Speed up-to 300Mbps
802.11AC or Wireless-AC – Speed up-to 866 Mbps
While older protocols still work getting a Wireless-AC unit is the best option.
Basically, when looking for a USB adapter, get a Dual Band Wireless-AC unit as it will fit into almost any network.

They also are out of the way and don’t take up any USB slots.
Be sure to check that there is an open slot in your PC to use and the type of expansion slot which is usually PCI.
Installing a card is not difficult but does require opening up the computer and inserting the card which may not be for everyone.
If you are wary of opening the case a USB adapter would be a better option.
Example Dual Band 802.11AC PCIe Wireless Card on Amazon

Setting up WiFi on a Desktop PC is easy to do with any of the above options.
The easiest way is to simply buy a wireless USB adapter with many units available in all shapes and sizes.
If you are a technical person installing an internal WiFi card is also a good option and can often see the best performance since there is no bottleneck from the USB.
Both internal and external WiFi card work well and most setups will have no problems with either.
Keep in mind some motherboards have WiFi built in and don’t have the option setup.
This is not common but depending on the motherboard your computer may already have built-in WiFi.
Check the boards documentation to see if it has this feature.
As always be sure to read reviews on Amazon, here, or elsewhere to be sure a unit is the right pick for you.
