Wired, wireless, all the same.

You are learning, questions are good.

Search Google for:
"Safe Layer 2 Security in-depth version 2" again, Cisco focused, but the
basics are there.

Learn the basics of *what* someone is trying to prevent. That is, you
need to better understand networking in general before you try to
prevent something bad from happening.
You are trying to 'fix' a single piece of a flawed networking system. In
order to 'fix' it, you need to understand it.

*ALL* systems have the ability to protect against *ALL* attacks, without
needing commercial software. You need to know what you are protecting
*against* to be effective.
I use commercial solutions for _pieces_ of our security strategy. The
only reason I use commercial products for some things, is because it is
easier, or it is cheaper in the long term. I run an Internet Provider. I
don't know everything about security, but I know enough about the
network to know *why* I should do something, and *why* I should
sometimes buy commercial software/hardware. You should *not* buy
software or install security software just because you saw it do
something. Understand *why* it does what it does.

I see that you are proceeding recklessly with 'testing' on your network.
I'm assuming you are running Windows, but it doesn't matter.
If you disregard my previous warning about using these tools on a
production network without knowing what you are doing, then these will
be of benefit to you:
- tcpdump / wireshark
I'm pretty certain that they are all available for win32 nowadays.
