Connection mode of the 802.11 Wireless Protocol. Ad Hoc is typically used for a link between two computers and I think it can be used to make an "Ad-Hoc" network of 2+ computers as well.
+
+To setup a Wifi Network!
+========================
+
+Current problems
+----------------
+Can setup an Ad-Hoc link to main PC from my Notepad but;
+Can see a AP but cannot access via TCP/IP or anything else
+Can Not use Internet just times out
+Drakconnect (the Internet Wizard) will not setup TCP/IP on Wireless crashes
+Do I use Samba to access wifi network?
+
+apradar shows me the AP
+ethereal show packets of UDP and other are transmitted and received but no TCP/IP
+changed hostname, now ethereal doing ARP to correct IP 192.168.0.1
+I know of dhcpd but it will not run!
+
+My Setup
+--------
+The wifi card's a Netgear WG511.
+www.netgear.com
+I have a Dell Notepad Inspiron 2650
+Intel Chip
+running Mandrake 10 KDE 3.2
+Kernel 2.6.3-7mdk
+
+Card Chip is
+Prism54
+firmware Intersil ISL3890
+ESSID: "$@4@M"
+
+To get card working follow these steps:
+---------------------------------------
+In Root (SU)
+# Download the latest firmware from:
+http://prism54.org/~mcgrof/firmware/1.0.4.3.arm and copy it
+to /usr/lib/hotplug/firmware/
+# Rename the firmware to 'isl3890'
+mkdir /usr/lib/hotplug/firmware/
+chmod 777 /usr/lib/hotplug/firmware/
+cp /home/leftfieldnz/Document/software/wifi/isl3890 /usr/lib/hotplug/firmware/
+# Remove and then slot the pcmcia card back into the laptop.
+# Run the following:
+modprobe prism54
+iwconfig
+# iwconfig should now list the card as: Network controller: Intersil
+Corporation Intersil ISL3890 [Prism GT/Prism Duette] (rev 01)
+# iwconfig should see the card as eth1
+
+From there you can follow the normal procedure for setting the ip address etc.
+
+BTW, if you want to run airsnort you need to set the card to monitor:
+iwconfig eth1 mode monitor
+
+Then startup airsnort, change the driver to 'other' and hit start.
+
+To switch back to non-promisc. do: iwconfig eth1 mode managed
+
+And here is the content of my
+cat /etc/sysconfig/network-scripts/ifcfg-eth1
+DEVICE=eth1
+BOOTPROTO=dhcp
+ONBOOT=yes
+HWADDR=00:09:5b:c2:c7:1a

+
+Since about 15 people a month seem to download them, and someone even requested
+them via email here are the 'new' WG511 drivers uncabbed.
+
+http://www.e-kyle.ca/stuff/WG511v210_uncabbed.zip
+
+I draw your attention to this relevent post.
+http://www.linuxant.com/pipermail/driverloader/2003q4/000280.html
+
+This could still be an issue. It doesn't seem to affect me though.
+

+
+Setting up the pcmcia card
+under Linux was harder than setting up the networking on my wife's mac
+powerbook, but not by too much. I had to download the firmware and
+place it in /usr/lib/hotplug/firmware, then use iwconfig to set the WEP
+key, set up the default route, and I was away!

+
+
+The laptop's an old Gateway PIII 550, running Mandrake 10.0 official.
+Kernel 2.6.3-7mdk.
+
+The card's a Netgear WG511.
+
+One caveat; this card is running the prism chipset (or at least, it's
+using the prism54 driver) Some people have reported that Netgear have
+changed chipsets on the WG511 a couple of times, so you can't guarantee
+that all WG511 cards will work.
+
+One other problem; the prism54 driver doesn't support WPA yet. WEP
+works fine tho', and WPA is coming Real Soon Now(tm) :-)
+
+BTW, the firmware is for the Intersil ISL3890. Googleing (sp?) for that
+should get a download site, or email me and I can email the one I
+downloaded. It's only about 90k.
+
+Install the LATEST version of libpcap. Please make sure that you have removed any old version of pcap that you may have installed.
+
+Make sure you have gtk+-2.2 installed as AirSnort is a gui application. You will also need gtk+-devel in order for autogen.sh to work.
+
+Perform the following steps
+tar -xzf airsnort-0.2.3a.tar.gzcd airsnort-0.2.3a./autogen.shmake
+Poof you're done. The airsnort executable is in the airsnort-0.2.3a/src subdirectory, do with it what you will. There are some man pages in airsnort-0.2.3a/man

+
+===============================
+
+Setting up the interfaces:
+
+When you run ifconfig, you might not see your wireless device. Use the command 'iwconfig' to show the wireless devices that are connected and set to use. First things first. You need to set an IP for this device. If you do not set one before setting the wireless options, you will not get a link.
+
+ifconfig <device> <IP address>
+
+Now to set it to link up with the wireless access point. once again we'll use iwconfig to set the ESSID, which needs to match the SSID of your AP or Router to link to.
+
+iwconfig eth1 essid MYWIRELESS
+
+Generally this should link you to the wireless AP. If it doesn't, you might try to set the wireless device a bit more. Some devices will not take some of these options.
+
+
+=======================
+
+I'm having problems getting my netgear wg511 to work. I compiled the
+drivers from ISL3890 fine and changed /etc/sysconfig/pcmcia to contain
+PCIC=i82365 & PCMCIA=yes. However, when I modprobe islpci_cb I get
+the errors
+
+Try changing your PCIC=i82365 line to "PCIC=yenta_socket"
