I have installed App Inventor on my home computer and the companion on my phone
My computer is connected to the internet using a nic card/cable (my computer has no wifi)
Using same modem/router, I am connecting my cell phone using the wifi
App Inventer says there is a connection problem to my cell phone
What is my problem?
Do I need to use the emulator? or get a wireless card for my computer?
Ideas?

Connecting over the Phone Over Wifi Troubleshooting
Try the following steps to troubleshoot your wireless connection.
1. Try to reach http://rendezvous.appinventor.
2. Try to reach http://rendezvous.appinventor.
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-
4. If all of these steps succeed and Wireless AppInventor 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
