Here is a high res pic of the board: http://www.bagpipes.net/files/front-linksys54g.jpg

Sorry for being a n00b but where do I need to solder on to? I found an old thread (wpc54g version2 external antenna w/ tnc jack) which says connect the pin to the end of C155 (top left corner of the image) but checking with a multimeter this appears to be connected to the GND points nearby. Maybe my multimeter isn't good enough to spot the very low value capacitor in between? In that case presumably I should just solder shield to one of these ground points...
