Here are several documents MIT has available for troubleshooting networks:

Connecting the phone over wifi▼

I'm using wireless and the phone won't connect to the blocks editor.

Try the following steps to troubleshoot your wireless connection.

1. Try to reach http://rendezvous.appinventor.mit.edu from your computer.
2. Try to reach http://rendezvous.appinventor.mit.edu from the phone itself.
3. If the steps above both work, try using the "ping" command to ping to the IP Address of the phone (displayed by the MIT AICompanion in its startup window). If you are using windows, type "ping" + *IP address of the phone* in cmd.exe window, if you are using mac or linux, type type "ping" + *IP address of the phone* in terminal window. Detailed instruction see http://www.wikihow.com/Ping-an-IP-Address
4. If all of these steps succeed and Wireless App Inventor *still* doesn't work, then there may be a firewall between the computer and phone that is blocking ports 8001 and 9987. If you have a "telnet" program you can attempt to telnet from the computer to the phone on these ports. If the connection won't complete, then there is likely a firewall in place that is blocking connections to the phone.

You probably have already been there, however you may not have looked here at the treads discussing firewall issues:    https://groups.google.com/forum/#!searchin/mitappinventortest/firewall     .   The list is a bit disorganized but there will be suggestions/solutions others faced while battling school network firewalls.

It may help.   If it does, let us know.   If none of this stuff works for you, please return and let us know what else you have tried.

Regards,

Steve
