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.
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!
The wifi card's a Netgear WG511.

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"
In Root (SU)
http://prism54.org/mcgrof/firmware/1.0.4.3.arm and copy it to /usr/lib/hotplug/firmware/mkdir /usr/lib/hotplug/firmware/ chmod 777 /usr/lib/hotplug/firmware/ cp /home/leftfieldnz/Document/software/wifi/isl3890 /usr/lib/hotplug/firmware/
modprobe prism54 iwconfig
From there you can follow the normal procedure for setting the ip address etc.
Then startup airsnort, change the driver to 'other' and hit start.
To switch back to non-promisc. do: iwconfig eth1 mode managed

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!

airsnort http://rpmfind.net/linux/RPM/cooker/10.1/i586/media/contrib/airsnort-0.2.4a-1mdk.i586.html
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

iwconfig lo no wireless extensions.

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"
