HOWTO

Remove right or left WiFi cover next to latch, and replace PC board antenna with an SMA connector mounted on a piece of bar stock. Solder connector to the coaxial cable, screw into existing mounting holes and then test with an external antenna. If satisfied, then cover area with epoxy or silicone. One other tip on antenna connectors is to use a standard female SMA and then couple it to the RP-style antenna connector with a center conductor from small coax such as UT-141. This antenna configuration allows me to use a 7 db Linksys antenna and regularly see 5-6 db of actual gain. Other antennas (dishes, loop yagis and omni verticals) do even better! Also can use amps!
