nfs3 over wifi works just fine for me, I use it all the time at home.
Setting it up was no different to setting up a wired interface - set
exports on the server, mount from the client.

I suspect the problems you are having are unrelated to wifi as such and
are probably something more mundane. I take it you've checked all the
usual suspects such as your current IP is allowed to connect to the
server, there's no access rules blocking you and so on?
