     Do a search for "Wireless Networking" in the archives. There loads of stuff
    there about WEP and detailed explanation about how Authentication and
    encryption works

    Subject: Dumb question abt. Wireless WEP security

    Hi all,

    There seems a general understanding that WEP is not secure enough, because
    theoretically WEP encyrption can be broken.

    The question is abot the practical usage; how easy it is for WEP to be
    broken?

    Does it suffice to sniff the wireless network for one hour, or do we need to
    sniff for few days? What happens if the wireless network is periodically
    stopped let's say every 10 hours for 15 minutes,

    Regards,
