Yeah, I have Knoppix DVD fixated 2008-03-26. I'm currently using it
to perform a memtest on another laptop which came to me complaining
of freezing up (WhenDoze). Fortunately, memtest is not selfish and
promptly surrendered the DVD upon request.
That's interesting. When I booted up on Knoppix and ran ifconfig, I
noticed that eth1 had an IPv4 address, something like 192.168.0.25 or
the like. That suggested to me that I was wirelessly logged into
someone's network. So I tried surfing the web. I went to the Knoppix
home page, CraigsList, and YouTube.
I rebooted on Fedora 9, but couldn't access the web from there. I
didn't have an IPv4 address. I did ifdown eth1, which made it
disappear from the ifconfig list but not from the iwconfig list. Then
I did ifup eth1. But eth1 wouldn't come back up, saying:
Determining IP information for eth1... failed; no link present. Check
cable?
But when Fedora 9 boots up, ifconfig lists it.
Why would Knoppix activate it on someone's AP, but not Fedora?
I'm going to go back to Knoppix. I'll let it run overnight, connected
(but not using the /borrowed/ network connection), and see if I get
any ipw2200 error messages in dmesg.

Hmmm, it would seem that whatever network I was connected to has since
been shut off:
$ iwconfig eth1

Bazaar, It's back. Maybe I have a weak signal and it just took a few
minutes of sitting on the table next to the window to re-acquire the signal.
Knoppix dmesg has encountered one of the ipw2200 error messages, but not
the one that is common in Fedora ("Failed to send ..."), rather the
other one "ipw2200 Firmware error detected. Restarting." and my
/borrowed/ wireless internet connection hasn't responded since. Oops, I
spoke too soon, Google just came up.
So, despite the firmware error, it appears as tho it is still internet
capable, using Knoppix, but not with Fedora 9.
Using 'iwlist eth1 scan | grep "ESSID\|key:off"', I can see those who
are not using encryption. The one that comes up consistently is "print
server 05B297". The others not using encryption do not come up
consistently in the scan. One is "default" and the other is "NETGEAR".
The latter seems to come up more consistently. I did "iwconfig eth1
essid NETGEAR" and iwconfig eth1 shows 'ESSID:"NETGEAR"', but
'unassociated'. How to I get it to try to connect?
I won't be doing any downloading or anything that slurps up the
bandwidth. I just want to learn how to set up a wireless connection,
and pull up a web page for proof. Knoppix, well, just worked. But
apparently I need to recite the magic incantation for Fedora 9.
(Back to Knoppix for now (so it can show me how it does with ipw2200
errors), and off to bed.)
