Not sure if this is relevant,
but as an experiment I tried to get NM (NetworkManager)
working with the F-7 KDE Live CD,
with a ThinkPad T43.

I didn't try for long,
but I couldn't get it to accept my WEP key
(yes, I tried hex and ascii).
It saw my access point OK;
but whenever I gave the WEP key, it simply asked for it again.

My conclusion: NM shouldn't really be part of a standard system.
I'm sorry to say this, as the NM people have been very helpful to me.
But in my experience, NM just adds another layer of obfuscation
to the already murky world of WiFi.
I think NM tries to do too much (eg including Ethernet as well as WiFi).
what is needed is something which does the minimum necessary
to get WiFi working.

The whole WiFi setup in Fedora could do with a fundamental re-think.
