Turn a external usb antenna into a mobile wifi antenna to get a better wifi signal. I work approximately 24 hours from my vehicle each week. I use my laptop while in my vehicle to access public wifi. My internal wifi antenna on my laptop computer does not get a good wifi signal. I purchased an external usb wifi antenna which gave me better range. I decided to modify this antenna so that I could mount the antenna on the roof of my truck. I saw a big difference in my wifi signal when I mounted the antenna on the roof of my truck.

Step 1: Mobile Wifi Antenna
Drill a small hole in one end of the project box for the external antenna. Take your dremel or file and cut a slot in the other end of the box for the usb cable to exit. Insert the wireless Lan card into the box and screw on the antenna. Plug in the usb cable and run it out the back of the box. Secure the top of the box with the included 4 screws.
