    laptop wifi from scratch - almost

    What are the steps one takes to get their wireless card working on a laptop. My setup thus far is the following:

    Distro - Debian
    Wireless card - Microsoft(What?! you say) MN520 (I know it works it did in Fedora FC3)
    Kernel - 2.6.12-2
    The kernel has been compiled for PCMCIA after which the lights on the card came on.
    An iwconfig returns " no wireless extension".

    I want to learn how to do this correctly so is there a step by step guide to do this. Generic steps to take. I have had a hard time googling this and everything from Debian seems ancient. This wireless stuff to me is akin to F'n Black Magic and I want to know what is going on.

    I think that card has a Prism II chipset, so you'll need to get the driver for that first. You'll need to create a network config script for it in /etc/sysconfig/network, for example if after the driver is loaded the device is wlan0, you'll need to build a config file called ifcfg-wlan0. I've only ever done this through mandrake so just giving you an idea. If you get your driver loaded I'll post a copy of my old config file and you can check it out and modify for your needs.

    Well this is what I have done so far:

    1) Put the following in /etc/pcmcia/config
    card "Microsoft Wireless Notebook Adapter MN-520 1.0.3"
    version "Microsoft", "Wireless Notebook Adapter MN-520", "", "1.0.3"
    bind "orinoco_cs"
    2) Then added the following to /etc/network/interfaces
    auto eth2
    iface eth2 inet dhcp

    wireless_channel 6
    wireless_enc on
    wireless_mode Managed
    wireless_essid Earth
    wireless_key 0xmykey
    3) My iwconfig now yields something whereas before it did not:
    IEEE 802.11-DS ESSID "Earth" Nickname "Prism I"
    Mode:Managed Frequency:2.412 GHz Access Point: "myActualAPMAC"
    Bit Rate 11MB/s Tx-Power=15 dBm Sensitivity: 1/3
    Retry min limit:8 RTS thr:off Fragment thr:off
    Encryption key:off
    Power Management:off
    Link Quality=90/92 Signal Level=1/153 Noise Level=111/153
    Rx invalid nwid:0 Rx invalid crypt:206 Rx invalid frag:0
    Tx excessive retries:0 Invalid misc:0 Missed beacon:0
    I am still not connected, but I am very close I can feel it. I think something might be screwed up in the encryption key. Any thoughts?
