I'm also having issues. Before I put my new power supply, cpu/motherboard, and graphics card in everything ran amazing with KDE4 on top of a minime install. But when I tried a fresh install after putting the new hardware in, I can't seem to get any wireless connection at all after the update. I am also watching the progress via the site, forums, and twitter. Hopefully when the new release comes out I can try again and have more success. I do love the distro and community. But for now i've had to go back to an old favorite starting with F. Their KDE4 system is actually somewhat nice at the moment.
