Antena wi fi for dell latitude pp01xc840


The reason you don't have an antenna is that there is no WiFi built in that computer.

Getting an antenna is not going to give you WiFI.

If you want WiFi, you must buy a USB WiFi adapter.

You can get an excellent one
HERE
You can also get a great antenna for it HERE

Or you can go downtown to a store that sells computer stuff and get an ordinary USB WiFi adapter that will probably work Ok.
