Please log in for more thread options According to a friend of mine, the fastest speed that can be attained using 802.11g equipment in Ad-hoc mode (Peer to peer) is 11Mbps. I understand, even though `g` equipment has a theoretical max of 54 Mbps, the 802.11 standard only ever required Ad-hoc connection to be max 11 Mbps. Can anyone confirm if this is fact ? -- Andy M Moore tubaman@tiscali.co.uk | ||||||||||||||||

If you go between b and g, it will only set itself for the lowest common denominator speed (in this case b at 11). I used to have one set up as one b one g and it ran at 11, changed to two g's, and now it's about 54. | ||||||||||||||||

Nope, but I can see where your friend is coming from. The 802.11g specification does not include any requirement to support Ad-Hoc mode at 802.11g speeds. A company could supply a radio that only does 11Mbits/sec in ad-hoc mode and still be 802.11g compliant. I just setup several WPC54G and WMP54G PCI cards in an ad-hoc (gaming) network. Works at greater than 11Mbits/sec but I didn't bother to check how much faster. One catch is that the WPC54GS "speed boost" technology does NOT work in Ad-Hoc mode. That's why we bought the cheaper cards. There's no guarantee that all manufacturers will work at 802.11g speeds in ad-hoc. For example, D-Link doesn't officially support it. http://support.dlink.com/faq/view.asp?prod_id=1482&question=ad%2Dhoc I guess you're just going to have to disclose what equipment you have and deal with the issue individually by manufacturer and product. -- Jeff Liebermann jeffl@comix.santa-cruz.ca.us 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 AE6KS 831-336-2558 | ||||||||||||||||
