WiFi Help?

Hello - I purchased a lap top recently and I am in search of what I would term a "WiFi Signal Booster" but when I google that topic, it doesn't seem to be what I have seen and am looking for.

I work in a position where I see a lot of traveling sales rep types, and many of them have a device that looks like an antenna. I presume the device would work something like this...

Plug antenna looking device into a USB port and boost the signal receiving ability of a WiFi enabled computer.

In other words, I have a lap top that I want to use in a low signal area so I need better reception. Anybody know where I can find something like that?

 

you might check this wifi antenna or Here

 

It looks like a coaxial cable connector, do you have to have that to use an antenna?

 

My laptop has a built in WiFi card (It's a Dell Inspiron). Can you get an antenna that utilizes a USB port?

Or, can you get an antenna that connects in some other way than directly to the WiFi card?

 

Linksys makes one that will do what you want. Here

 

Maybe what you are seeing the other people use is a wireless USB adapter?
