Habilitar Wireless INTEL Ipw2200 lenny y squeeze

Installation on Established Systems

The ipw2100 and ipw2200 drivers are included in the mainline Linux kernel since 2.6.14 and 2.6.15 respectively. They are included as modules in Debian kernel images.

Firmware is required to be installed prior to driver operation.

Lenny, Squeeze

1. Add a "non-free" component to /etc/apt/sources.list for your Debian version, for example:

   # Debian Lenny/5.0
   deb http://ftp.us.debian.org/debian lenny main contrib non-free

   or

   # Debian Squeeze (testing)
   deb http://ftp.us.debian.org/debian squeeze main contrib non-free

2. Update the list of available packages and install the firmware-ipw2x00wireless-tools packages: and

   aptitude update
   aptitude install firmware-ipw2x00 wireless-tools

   You are required to accept the license agreement before the firmware is installed to your system. 
3. As the driver may already be loaded, reinsert the relevant driver module to access installed firmware:

   modprobe -r ipw2100 ; modprobe ipw2100

   or

   modprobe -r ipw2200 ; modprobe ipw2200

4. Verify your device has an available interface:

   iwconfig

5. Raise the interface to activate the radio, for example:

   ifconfig eth1 up

6. Configure your wireless interface as appropriate.
