Internet sharing stopped working

[RhineEllery]

So I've been using Internet sharing on my Macbook (OS X 10.6.8) for about a month in order to connect my iPad mini to the internet.

I've been using sharing via ethernet to devices using airport.

I don't know what happened, it just stopped working overnight.
My iPad can see the network and will try to connect to it, but it doesn't work.

Please help me, I've tried everything I can think of!

As we do not know, what you can think of, how about listing the things you already tried, thus we do not repeat the to you.

Have you restarted your Mac and iPad mini yet? Have you disabled and enabled Internet Sharing on the Mac yet?
