random other mod today...
the built in laptop wifi doesn't work so good when it's sitting closed in it's cradle down in the back of the jeep right up against the metal body panel. today i found that i had a netgear wn121t wireless adapter sitting in a pile of parts, so i decided i'd try it out for the carputer.
i opened up the case and took out the circuit board which has an integrated antenna. then i threw some shrink wrap around the exposed wires near the end of the usb cabe, and used some gorilla tape to seal the whole thing up and make it all black.
i'll double-sided tape this flat to the rear side window near the laptop dock and that should get me a little better wifi reception. not as nice as an external antenna, but it was free!
