Can't use touchpad to click in latest KDE

[ONEEYEMAN]

Hi,
I installed Gentoo on this DELL laptop, then installed X and KDE.
So I now have KDE platform version 4.12.5.

Everything works, but 2 things: I can use touchpad only to move mouse cursor, no clicking. I can use buttons to click, but since its a laptop, I'd like to have this functionality as well.
Also wireless card does not work and I'm starting to suspect I need to turn on radio on the keyboard somehow without going back to Windows.

Any idea what I can do to fix those issues?

The laptop has F2 key marked with the antenna, but simply pressing the key does not help.

Thank you.

Does it works on the login manager and in any other desctop environment? if so than it is a kde related issue, if not than it is a kernel issue.
