It's a wireless N card.
I've noticed other people adding antennas to their cardbus cards
havent found anything on wireless N though.
Trying to somehow attach an mc/mmcx connector somehow.

Any help would be appreciated.

Thanks

Thanks for your reply Jeff.

I'm not sure what type of connector they are; doesn't seem as if you
can connect anything to them. Definitely not Hirose connectors, there
is no pin in the center, just a hole.

Speed is not a big issue, all I have is a G router.
Do you think this will work:
I disable the original antenna by removing the capacitors C51 & C107.
Solder the pigtail to end of J4 (or L24) and connect J4 to J6 (or
L24).
If that doesn't work try connecting separately, test results.
How can you determine if you require reverse polarity? I assume if I
use an N connector it souldn't matter SMA does?

Thanks again.

Thanks again Jeff.
I'll start destroying and see what I get out of it.
BTW I love your Salad-Dish!!!!!!
