Do I Have The Hardware For Wifi In My Computer?

I see that my computer (Dell Optiplex 7010 SFF Desktop, Intel Core i5-3470 3.2GHz Quad Core) has the following network hardware:

I guess the network hardware is built into the motherboard. (I see 2 empty pci slots in my computer.) I don't see any antennae though I don't have much knowledge of what that would look like.
I think I don't have hardware to connect to wifi. Am I right?

 

I agree your computer does not have it - but it is easy and inexpensive to add. There are USB adapters or PCIe card adapters.

I prefer those with external, movable antennas.

 

The manualmight be useful to keep- shows Ethernet port --Page 9 in the manual , shows an optional wifi antenna connection- check on yours .

I don't see an antenna on the back. I also don't see any port where an antenna would plug in. Maybe different motherboard and case for those models. Or, I'm not looking closely enough for the port.

 

Then see post 3 -Digeratti suggested the usb type, or, PCIE CARD- USB type is simpler- just plug in- I found they worked well when I had touse one, and very cheap topurchase.
