I guess: not anymore. The last ones I saw without firmware were in the 11MBit era of wifi. All the new ons with 54Mbit and up are actually so-called "software defined radios" which are not more than a multi-purpose HF chip plus a controller which can be used to programm (nearly) any functionality into the hardware. I remember some of the Atheros-based cards were/are very sought after by amateur radio operators and hackers (in the white hat meaning of the word) because you can reprogramm them to be _any_ type of radio in the frequency range from 800MHz to 6000MHz. > 2) Is the RAM built into the Wi-Fi card chipset?

It would seem that way, yes. Grüße, Sven. -- Sigmentation fault. Core dumped. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
