Check if your system and switch firewall is allowing port 80. Here is what you should do to figure it out from a remote machine in your network:

$ traceroute <IP_on_which_python_server_is_running>

Also try:

$ telnet <IP_on_which_python_server_is_running> 80

This will help you to figure out if the port is accessible or not.

I'm trying to view a website I am building on my Mac on an iPad that is connected on the same LAN on the same Wireless AP.

I've got the right IP address, I can load up the page just fine on the same machine (http://localhost)

and this is how I started the server sudo python -m SimpleHTTPServer 80

What are the steps I can take to figure out why connections from other machines on my network don't work?

  Have you figured out what the exact problem was ? I am facing the same problem at the moment and found this very old question

  The question is too old and not specific for me to remember what I was doing so I do not remember what the resolution was. But it sounds like if you have a third unix computer you can use traceroute etc. like the answer says.

Ah, yes, traceroute and telnet. good tools that I have used before but forgot about yesterday.
