I'm trying set up th beagle board as an access point using a USB
dongle. Can any one recommend one? Or working one?
i struggled with this a year or so ago. there are only a few usb chipsets
that work as an access point but the problem is manufacturers
are always changing designs. so you see a post where the XYZ
works but when you buy one the vendor/product ids have changed
(new chipset) and they don't work (they work fine as clients usually)
maybe the situation is better now.
here's the table of working chipsets; you want AP mode and USB.

Yes, I saw the same table. That is what I'm struggling with buying a
USB dongle with beagle board or buying a pandaboard with TI chip set.
It indicates the TI chip set can work AP mode. Was hoping some has
tried this to help not buying HW that does not work...
