Finally fully back to PCLOS. Although I am on the gnome 2010 version now, I am posting here because I had the same problem with kde. In the network center, my wireless adapter is being recognized, but I can not see any available wireless connections. I myself use a wired connection, but I often bring my laptop to work and sometimes need to pick up a wireless signal. I know that there are wireless connections in my building, so they should be showing. Btw, Toshiba Satellite L305-S5955. Also, with 2009, there was a problem with wireless not showing up at all, but that was easily fixed by upgrading to one of the testing kernels available at the time. However, I have the same problem with all the available kernels in the 2010 repos.
Thanks in advance for all replies.
