    Hi Group,

    I am new to Cisco and I am about to start CCNA course in the next few
    weeks - but I want to learn as much as I can before to maximise what I
    get from the course.

    Work has provided me an old C1801 router and spare 1142n Aironet with
    automous IOS installed to learn with. We have no CCNA as all our
    network support is outsourced.

    I want to setup the 1142n to have a wireless network with WPA2

    I am confused about radius server section on the 1142n? Do I need to
    configure radius on the Cisco1801 to authenticate the WPA2 connections
    or is this done on the 1142n?

    If I need to configure on the Cisco 1801 could someone point me to the
    command sets to review?

    Also how do you factory default the 1142n as the one I have has had a
    previous setup which?

  2. Sure. I recommend reading the Cisco installation docs, and following
    along. Their documentation is pretty decent, the intro stuff does walk
    you through the basics pretty quickly and efficiently.

    The router generally you'll be expected to do command line access on
    it with a serial port, so make sure you have a working serial port/USB
    dongle first and console cable.

    Go through the motions of setting a simple IP address on an interface
    with the Quickstart guide.
    The 1142 quickstart guides generally refer you to the web GUI on the box.
    It may just be me, but I feel the CLI is still much easier on the AP
    than the GUI, but the docs for the CLI of the 1142 aren't as good.
    You need RADIUS in order to do enterprise level authentication, or if
    you are doing a more advanced security model with 802.1x and certificates
    and such. Cisco has both a built-in RADIUS server for authentication
    on the 1142, as well as the option to use an external one. Or you can
    forgo that altogether and just use pre-share-key (PSK). Cisco does
    de-emphasize PSK quite a bit for their WiFi stuff, but it can be done.

    Start with the Quickstart guide, and the installation manual in the
    Cisco docs. I'd point you to some URL's, but Cisco.com seems to be
    down today right now.

    It's not just you! http://cisco.com looks down from here.

    Console in and 'write erase' and reboot. Or do you need to do password

    Once you have some basics on your routers, be aware that
    you can now emulate a whole network of cisco
    routers on your PC.


    It runs real cisco code so you need to have access
    to real cisco software images. Someone with a clue
    might be able to find some on t'interwebby.

    I might eventually read emails sent to me on this
    junk account.
