CentOS4, KDE3.3 and 128 WEP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



That seems a bit better so I can add the 128 bit WEP code.  But for some
reason I still can't activate it.  I get:

SIOCSIFFLAGS: Resource temporarily unavailable

which does not point too far.

I have checked that the atmel_cs module is installed (the card is a Belkin
F5D6020 rev 2).

I have tried an strace and it seems to be looking for a file libc.mo in
/usr/share/locale/[en.UTF-8|en.utf8|en]/LC_MESSAGES but there is one in
/usr/share/local/en_GB/LC_MESSAGES and pretty nearly every other locale
which are all in glibc-common.  

I guess this is because I switched from en_US to en_GB when I installed -
ie I unchecked US English.  I don't seem to recall having this problem 
with other machines although this is the first one that I have tried
to use wireless with...

I tried changing LANG to be en and I get the same result although the
strace now fails rather earlier.

So it seems at least that I should reinstall en=en_US but I am not
convinced that this will solve the problem. And where is it anyway?  I
can't see it in any of the CentOS4 rpms - I have been through all 1404 of
them.  It seems to be installed from somewhere when you set up CentOS4.  
Surely I don't have to reinstall?

Clues?

TIA
