With these Tyco MiniPCI U.fl cable WiFi antenna for laptop retail - eBay (item 370349619251 end time Jul-12-10 08:59:37 PDT)
The stock antennas were giving me shit. Low signal strength.
The new antennas are great, much bigger and more quality feeling than the stock ones, and I get perfect signal now.
What netbook, and do you have any pics of the process?
I'd love to do something like this on my Eee 901.
