Re: ural-linux and kernel 2.6.14-*
Update : WPA and 2.6.14
ural + WPA (wpasupplicant) don't work with 2.6.14. I think this is
because of wireless extension v19.
A workaround :
I downgrade to wireless extension version 18
http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html#wext
After patching the kernel to wireless extension 18, ural-linux works
with WPA using wpasupplicant version 0.4.2 (not 0.4.4).
