I have asked a similar question on the Ubuntu pages but this is likely a generic Linux issue: what variety of wireless cards/drivers will support being placed in a bridged connection? I have been using very old Prism II hardware as it worked while I believe more recent cards did not, but the old hardware died, killing the bridge.

I think that youarn't go in the right direction. I would suggest to you to choice on wireless card and then look for its bridge support in the 3.x kernel. Here you want us to give you a list of supported cards, which is hard to get, since there are many manufactures out there, and many cards are with same design and so on. –  Hanan N.

Thanks for the comment. My thought was that there are a limited number of chipsets out there - I am not looking for a recommendation on a brand or manufacturer, but on the broad characteristics of the card. –  adrianmcmenamin Dec 30 '11 at 0:33

According with the hostapd guys, wireless cards that fits better as a AP or even a WDS(that obviously, requires a bridge interface) are:

  • Linux mac80211 drivers
  • Linux drivers that support nl80211/cfg80211 in AP mode
  • Host AP driver for Prism2/2.5/3
  • madwifi (Atheros ar521x)
  • BSD net80211 layer (e.g., Atheros driver) (FreeBSD-CURRENT)

There is no list, but generally, prism drivers and mac80211 ones that uses SoftMAC(more control over the configurations through software) will work just fine.
