Thanks Alex. Great information. Do you use a min-usb to normal usb cable/adapter for working with the gumstix?

The edimax is discontinued =\ looks awesome but i can't find an online supplier. I love the external antennae.
The belkin looks good (even w/ bad reviews mostly from 2005). I may give that a shot but I'm concerned about range. External antennae would be great but the belkin one also is cheap. Pros/Cons as always.

Thanks again for getting back with me.

Sincerely,
Blaine

You can use wifi dongles without powered hubs, at least just one.

We've been using wifi dongles for over 2 years on one project.

g not n though. Belkin and edimax dongles both work very well with
aircrackng and scapy. Edimax EW7318USG with external antenna which is
nice if you need to use an extension cable to mount the antenna on the
outside of the case/equipment box.Or belkin F5D7050
Both also work nicely if you need to do packet injection.

Also the huawei E620 USB Modem(gsm/3g) works nicely.

Using the wifi dongle also spreads the heat sources around.
