    strange results involving functionality of ethernet and wireless

    About a week ago, my ethernet card stopped working, but i
    figured out that it still worked in Windoze98 and in Morphix.
    a few days later, my wireless pcmcia card stopped working too, but
    again, it works in windoze98 and in Morphix.
    I have re-installed mandrake 10.1 twice with the original cds I had,
    then finally with a newly downloaded DVD, and there is no change in
    this behavior. I have tried all the configuration methods I know of
    and still no go, however Morphix has them working totally effortlessly,
    just like it used to be in Mdk 10.1.

    some additional info...
    the machine in question in a IBM thinkpad T22 that I use both at home,
    off a network and at work on the net, I am somewhat of a n00b, but use Linux as my primary OS 99.5% of the time.
    here at work, I am setting up an apache server, an FTP server and an
    email server on a seperate machine(s) but have installed various programs to my laptop temporarily, to simply investigate them and read the docs. I have no-doubt done some stupid, dangerous stuff from a security standpoint on this machine like running gui as root, etc.
    I figured that a reformat would handle whatever crap I could get myself into, but here is the thing- to protect myself from data loss, I have the large
    majority of my disk partitioned as /mnt/uzr where I keep everything I do not
    want lost- music, pictures, my personal files etc, no programs or anything
    just files, this way when I reinstall, I leave this partition alone and mount it again in the new installation... works beautifully.
    I am wondering however if my issues could be stemming from something hiding on this partition. I have looked through every single folder twice
    and there is nothing out of the ordinary of unrecognizable.
    I have run rkhunter and another root-kit checker without results.
    I know little about security issues but obviously need to learn.

    can someone give me some advice, suggestions, ideas, anything!?
    this is very perplexing

    When my eepro100 went to the NIC graveyard, it's MAC was reset to FF:FF:FF:FF:FF:FF. I'd think that the other events are unrelated. The MAC *can* be spoofed by ifconfig, so I'd reboot onto a livecd (to make sure that no initialization scripts had been modified) to see what the MAC is there. If it's still FF:FF:FF:FF:FF:FF, time to get a new NIC.

    The ethernet card works normally with a live cd and in windoze98,
    just not in my mandake installation.
    this is what is so confusing since I've reinstalled alot even with a new download.

    any thoughts?

    DOS attack?

    could this be some form of Denial Of Service attack?
    how could I figure that out?
    I'll be reading up on DOS attacks in the meantime.

    finally fixed!

    I was able to fix this problem by re-installing yet again-(fourth time now) but this time,
    unlike before, I changed and lengthened all the passwords and it worked, just like before- effortlessly. This further supports my theory that there was some form of intelligence behind my problems and my password had been compromised.
    I know re-installing is not the ideal was to solve anything, but for three minuites of work
    resulting in a solution, Im not complaining!
    my big lesson from all this...running GUI as root on a network IS as stupid as everyone
    says it is!
    lookout fellow newbies!..
