A couple of questions (well four actually)
1. Recently on ebay I bought a (or what I was told was a) Orinoco gold card. When I got the card it had no sticker on it or drivers. I managed to get it working by downloading drivers and I had to specify orinoco 5V driver and this got it working with netstumbler (yay). What I want to do is upgrade the firmware to give the card an identity as currently it doesnt pick up what drivers it needs and some of the software like the signal meter doesnt work (no wireless card found it says although its obviously there).
Do you have any links to things I might try? ive had a look but all I can see is articles about flashing orinoco silver cards to gold. 2. Does windows 2K/XP have any sort of utility to create an ad hoc network? my other wireless card (which doesnt work with NS realtek based) used to have an option to connect to ad hoc or infastructures but since re installing this has gone and ive done everything to get it back?. 3. The card has an MC lucent connector on it for connecting an external antenna. I want to get a 19db one and put it on the roof. WIll I have to connect to it by a pigtail converter as no large antennas I have seen have the small lucent connector....and the pigtails seem to be only about 50cm! I need about 5 or 6 meters 4. With the external antenna...do I need to power it in some way? the orinoco card is 5V and im unsure how it will use the huge surface area of the antenna with such a low voltage. Am I thinking about this in the wrong way? |

Antennae are usually passive devices and are not powered. There are "amplifiers", which as the name implies, amplify the radio signal. However, if you don't know what you are doing, an amplifier is potential DANGEROUS to yourself and others. The manner that the question was asked, and the fact that you're even asking this question indicates you do not know enough at this point about using such devices. You have to learn to walk before you can run. At this point you haven't even begun to crawl. Learn the basics of RF first.

1. Sounds like someone peeled the stickers off your card because you got a re-branded card. In Xp (and maybe 200) you can force the card to accept the wrong drivers (read the dell truemobile 1150 thread) so you can upgrade the firmware. 2. Yes, XP has a built in client manager that can run in ad-hoc mode. 2000, you will need to download the orinoco client manager for for your card. 3. Is this a question or a statement? My suggestion is to get a jumper cable made of low loss LMR cable. It would go between the pigtail and the antenna. 4. Your card should not need an amplifier to drive this antenna. Make sure you do NOT violate the maximum power/antenna gain in this chart: http://www.cisco.com/univercd/cc/td/...g/bkscgaxa.htm High gain antennas can be dangerous, do not look at, stand in the path of, or aim at anyone else.
