Please log in for more thread options The only limitation would be what 802.11 functions the vendor decided not to support in a device mean to be used as STA-only. [Frankly, if I were designing an 802.11 module, I would simply integrate all functions, and disable as necessary, if even that, but that is another matter.] I looked around USENET a bit and saw that this question was already asked at least once, and several people responded by asking, "Why would you want to do that?" Well, I still want to do it, and I am certain that it is what I would ultimately want to do, all things considered. I am not a noob - I do research in computer networking, so helpful responses will be helpful. :) [Must be Windows for now, not Linux]. Thanks! -Le Chaud Lapin- | |||||||||||||||||||||||||||||||||||||||||||||||||

Please log in for more thread options I would say that a Windows PC can't be an access point, but maybe a PC plus an 802.11 NIC can. In that case, you would either only have access to that PC, or it would have to act as a bridge or router. I believe the Internet sharing feature of windows would allow access through to another network connection to the internet. -- glen | |||||||||||||||||||||||||||||||||||||||||||||||||

> maybe a PC plus an 802.11 NIC can. =A0 :| I am currently reading the 802.11 standard: http://standards.ieee.org/getieee802/download/802.11-2007.pdf Before, I was too cheap to pay IEEE for a copy, so I got my information from secondary sources, but now it is freely available. :D It is obvious from the document that those who make WiFi dongles enjoy feast not tasted by many. The harwdare vendors have the option of including or omitting certain functions that would be provided by an AP. Some vendors took the liberty of simply including every function prescribed in the standard, as it eliminates multiple version syndrome. > In that case, you would

Actually, I am not trying to achieve pass-throught. I intend to set up a proprietary DHCP-like system inside a PC, and attach a WiFi dongle to the PC to test it with PDA's, each having their own Wi-Fi transceiver. I simply have to find a full-featured dongle for the PC, and a corresponding driver that exposes 802.11 services primitives to a user-mode API. Microsoft already encourages this scenario using Windows CE, making a PDA act as the AP: http://msdn.microsoft.com/en-us/library/aa450270.aspx -Le Chaud Lapin- | |||||||||||||||||||||||||||||||||||||||||||||||||
