Most things will do EAP-TTLS/PAP these days. Windows XP/7 are the
only real big exceptions I'm aware of. And if XP is a problem then
that's the least of your issues.

It doesn't *technically* need installing. But then you're open to
your devices talking to a rogue RADIUS server and giving their
cleartext password away. So it's pretty stupid not to.
They stopped their instructions before the big certificate warning
appears on screen.
With wireless, for example, this means little more than someone
coming near your site advertising your SSID, and people hit the
"trust this wireless network" button and immediately give their
So yes, it needs installing.
But then, you should install a client CA root cert with pretty
much whichever EAP method you use, otherwise you risk the same
