should. done it with a belkin g54 usb. I put N connector to it also to connect it to a 1w wifi amp.
here is a pic of the inside of my promix usb wifi card
it has 2 large solder traces on the board which would be the antenna
if i were to solder a small legth of antenna wire to them and conect a n-type connector to the end so i can attach a proper antena.. would this work..
would i use both solder tracks?
i hope this makes sense?
yes. by the picture you posted i recommend soldering the center wire of the N connector to the conection on the left. I will get pictures of mine posted later today.
center pin of n connector solder to the left, solder the outer pin to the right.
well i fonally got around to this..
its working fine (outside the car)
sorry bout the quality of the pics.
here is my little wire from the board
out the little hole i drilled
the antenna, its about 20cm long and ment to have a 7db increase
and the verdict..
i didnt think it would actualy make much of an increase because ive got about 2m of wire b4 the antenna.. i just wanted to be able to have an external antenna cus the car blocks out to much
but it actually does a little
dunno all that much about wifi (yet) but i believe i read something about two antennas not being all that good.
I think you'd be better off to just loose the internal antenna and connect your wire directly to the leads that go to the metal pads. (if this makes any sence)
A good starting point about wifi is netstumbler.org, might be worth checking out what's going on there.
Hope this helps

If you still care...
If the two meter cable run is the same lmr195ish stuff shown in the picture, replacing it with some lmr240 would almost certainly decrease signal loss noticibly.
also if you desolder the shield of the coax from the 2nd antenna and solder if to the casing you should get even better signal, by soldering the line to the 2nd antenna your not giving the cable a good shield.
