Are there any USB wireless adapters out there that support 802.11g in AP mode under Linux? Binary drivers are a no-go, as I plan to use it with an ARM device. Support for WPA would be very desirable as well.

Try a D-Link device. They have an excellent record of using Atheros chipsets with superb linux compatibility.

Try looking on Linux-Drivers.org for compatible hardware.


I have a TP-Link device with an Atheros chipset (which I believe all their devices use). Plug 'n play :)

Looks like I was wrong on this one (see comments)

  • And it supports access point mode under linux?

  • I've only used it once as an AP to test, but it seemed to work just fine.

  • Your asking made me second guess myself, so I dragged out the adapter and I couldn't get it into master mode. I'll let you know if I manage it, but at this stage it looks like I was wrong. Sorry.

I'm not sure about non-x86 support, but I could get a ralink PCI card to work in Master Mode very easily (after a lot of previous attempts). I've posted the details in my blog.

I know that USB ralink cards are more trickier to work in Master Mode, and I don't know the current status for USB cards, but you might check the rt2x00 project forum.

So, besides prism54, you might also try ralink (rt2x00 driver) devices.


It appears that the Linksys WUSB54G is supported by prism54, which claims to support AP mode, so I'll give that a shot. Moshen pointed me to linux-drivers.org, which pointed me in the right direction.


The WUSB54G has multiple variants, not all of which are supported by prism54. I ended up finding a Netgear WG121, which worked nicely through prism54.


Using Atheros USB devices in AP mode you'll be limited to 7 or 8 connected stations.
