Till Straumann has created a Linux distribution for Airport (to run Linux directly on the Airport or RG-1000 Access Point)
have created, a Linux distribution which directly on Prism II Access Points (such as the US Robotics, SMC or Addtron Access Points)
is a wireless distribution specific to Linksys WRT54G Access Points
They come in two parts, the first part runs between the card and the Access Point (802.1x, WPA), the second part runs between the Access Point and an authentication server (Radius)

Prism II Access Point HOWTO
How to configure "PRISMII" chipset PCMCIA cards as IEEE 802.11b compliant Access
Prism II Access Point Mini-Howto Prism II Access Point Mini-Howto (aka 'The $40 802.11 Access Point') by rose at@-- cafwap dot net Version 0.1.8 Last Updated 1/14/2002 How to configure 'PRISMII' chipset PCMCIA cards as IEEE 802.11b compliant Access Points DISCLAIMER: Like everything else on the net, I, the author, take absolutely no responsibility for the repercussions or use of this document
0.0 Prerequisites 0.1 Mental mindset Setting up an 802.11b access point using PRISMII based cards isn't a simple process.
If you're not comfortable editing Makefiles or configuration files you probably should not attempt setting up an access point on linux
Save yourself the frustration and go out and buy a cheap hardware access point
:-) Actually, setting up an access point might not be so difficult by the time you read this
At the time of this writing, the latest version of the PRISMII drivers for linux was 0.1.8, and very few people on the mailing lists had announced they had successfully set up an access point, and no one had yet documented the process
0.5 Access point firmware You will need to obtain the PRISMII firmware image, usually a .hex file, that allows your card to act as an Access Point

Wireless Attacks and Penetration Testing (part 1 of 3)
A three part article on wireless penetration testing discussing the different
types of attacks that...
First, and perhaps most obviously, an attack using the 'physical' layer in a wireless network is much easier than to attack the physical layer of a wired network -- the physical layer is the air, the general vicinity around a particular access point
Attackers don't need to gain access to your internal corporate campus; they can simply drive by and begin their attack from a car or even a nearby shop or restaurant, depending on how your access points are laid out
At the data link layer of the OSI stack, again one can point out numerous ways in which DoS attacks are simpler to launch against wireless systems than against traditional wired networks
Here's how that might work: say there is an access point, named AP, with diversity antennas A (for the left side) and B (for the right)
If user 1 and user 2 are on opposite sides of the office, then each user by default accesses a different antenna on the access point
By increasing the strength of his signal to at least equal, if not exceeding, user B's signal on antenna A, then the access point will no longer send or receive data from user A
Spoofed access points are another problem with the data link layer on wireless networks, even with WEP authentication

SecurityFocus: Wireless Honeypots
Article discussing the use of honeypot technology to combat attacks on wireless
networks.The human dependency on those technologies has increased to the point where one can find wireless devices almost everywhere, from network devices to laptops, cameras, and so on
This paper won't cover those points, but will instead focus on the core of the subject: wireless honeypots
In the blackhat community, most skilled or curious individuals enjoy penetrating wireless networks because they seem to be: safe: you are not really connected while attacking and you could run away in case of detection (ex-athletes areprohibited); easy: there are still a huge number of open or non secured access points everywhere (hotspots in hotels, airports, public areas, SOHO wireless networks, etc)
One could use something like automated scripts simulating network sessions between an Access Point and its clients, as we'll see below, or use tools that replay recorded packets such as tcpreplay
If you choose to use a real Access Point, then you can safely plug it on a wired network (with at least one computer) with visible resources playing the role of targets on this fake network, and invisible resources to record data and detect intrusions (data capture)
Progetti WiFi per radioamatori
Sono descritti alcuni progetti WiFi interessanti per radioamatori: amplificatori
InternetRelayChat: Callsign: Hosted on Projects Bidirectional WiFi amplifier for 2.4GHz ISM band - WiFi Link Extender Rast2432 [490k - 21/01/2006 - PDF] This project is a bidirection amplifier which permit to achieve up to 30Bm of output power from commonly used access points or WiFi cards (PCMCIA, PCI, USB)
For example, using DWL2000, to achieve best power and linearity it is convenient to set TX power as High but not Highest nor Medium Amplifier does not work with my Access Point at speed higher than 11Mbps Really? The amplifier works with 802.11g, setting the appropriate TX power
WRT54g does not work, with the amplifier, at 48 and 54Mbps! Which bitrate should I use to increase the coverage? To extend the distance coverage, you need to setup the access point to use power-efficient modulations, so it's recommended to set 802.11b standard (bitrates up to 11Mbps), which uses constant envelope modulations (constant power); also, consider that noise immunity increses as bitrates decreses, so to extend the coverage at the maximum value, set bitrate to 1 or 2Mbps Which antenna should I use? It's convenient to use high gain antenna, because it's supposed that you need the amplifier to extend the WiFi coverage, so do NOT connect the amplifier to the small-gain antenna shipeed with the access point, but use high gain directional antennas (11-24dB gain, sectorial, log, yagi, dish) or omnidirectional collinear antennas (6-12dB gain)

Ad hoc networks have multiple wireless clients talking to each other as peers to share data among themselves without the aid of a central Access Point
An infrastructure WLAN consists of several clients talking to a central device called an Access Point (AP), which is usually connected to a wired network like the Internet or a corporate or home LAN
Once the NIC finds the correct channel, it begins talking to the Access Point
Bandwidth on an 802.11b network is limited to 11Mb per access point
This 11Mb is divided among all users on that access point
Because the 802.11b standard does not contain any specifications for load balancing across multiple access points, devices that strictly adhere to the standard have no answer if you find your network becoming over populated
By default the Access Point broadcasts the SSID every few seconds in what are known as 'Beacon Frames'

3) Access points and routers all use a network name called the
4) Each piece of Wi-Fi gear possesses a unique identifier called the "physical address" or "MAC address." Access points and routers keep track of the MAC addresses of all devices that connect to them
5) In Wi-Fi networking, the access point or router typically broadcasts the network name (SSID) over the air at regular intervals
Fortunately, most Wi-Fi access points allow the SSID broadcast feature to be disabled by the network administrator
Turn off DHCP on the router or access point, set a fixed IP address range, then set each connected device to match

Securing Your Wireless Network
Tips for home users to secure their wireless LAN, with detailed instructions on
how to execute each...
Nevertheless, taking a few extra minutes to configure the security features of your wireless router or access point is time well spent
Here are some of the things you can do to protect your wireless network: 1) Secure your wireless router or access point administration interface Almost all routers and access points have an administrator password that's needed to log into the device and modify any configuration settings
As soon as you set up a new WLAN router or access point, your first step should be to change the default password to something else
Without it, the only way to access the router or access point may be to reset it to factory default settings which will wipe away any configuration changes you've made
2) Don't broadcast your SSID Most WLAN access points and routers automatically (and continually) broadcast the network's name, or SSID (Service Set IDentifier)
6) Reduce your WLAN transmitter power You won't find this feature on all wireless routers and access points, but some allow you lower the power of your WLAN transmitter and thus reduce the range of the signal
