1 edit | firmware upgradable?
My understanding has always been than existing b/g hardware would not be firmware upgradable to 802.11i/WPA2 due to various cpu and other hardware alterations within the circuits? As mentioned in the Article itself.

Elk Grove, CA | If the card or access point has a dedicated AES chip (I believe Zyxel and some Netgear's has this) all it would take is a software/firmware upgrade to use the cchip for AES processing. |

WPA support should be in the Radio unless the vendor is implementing host mode AP functions (processing and encrypt/decrypt raw frames in CPU environment). Most AP implement AP functions in the card firmware itself (firmware AP). They download the AP firmware to the card and card (wireless module) does the enryption and decryption. For this reason if the card firmware could be upgraded to handle AES than WPA2 upgrade could be done. |

I believe soft radio based 802.11b/g cards should be able to support the new standard. Atheros and Broadcom 802.11b/g and 802.11a/b/g cards come to mind. |
