If this is happening to you, you can disable mobile networking (cell phone carrier based Internet connectivity) from your device's settings menu. If you use a wireless Comcast router, there's a very good chance that it's functioning as a public hotspot for any Comcast customer wandering by. On some devices and in some locations, even with Wi-Fi enabled, the phone continues to use the cell network. For detailed instruction setting up a computer as a router, see Why is my phone still not connecting?Ĭheck that your device is connected to Wi-Fi and not the cell network. A way to get around this is to use your own or a local computer as a Wi-Fi router and have all computers and devices using App Inventor connect to the network using the new router. Many networks have firewalls set up that block connections to the phone. If you do not pass step 4, your network most likely looks like this. Of course, by using another WiFi router/access point as a wireless bridge, you could connect a CCTV DVR to your router wirelessly. If the connection won't complete, then there is likely a firewall in place that is blocking connections to the phone If a CCTV DVR or NVR don't have a built-in WiFi support, then you have to run internet cable (CAT 5 or CAT 6 Ethernet cable) to connect your DVR or NVR to the internet via the router. If you have a "telnet" program you can attempt to telnet from the computer to the phone on these ports. 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 80. 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. If the steps above both work, try using the "ping" command to ping to the IP Address of the phone (displayed by the MIT AI2 Companion in its startup window). Try the following steps to troubleshoot your wireless connection:ģ. Ideally our network situation should look like this: Connecting over the Phone Over Wi-Fi Troubleshooting Device and computer communicate directly using IP
MIT RendezVous Server tells the device and computer with the matching 6-character code the other's IP addressĦ. MIT RendezVous Server records the IP address of your phoneĥ. Your device checks in with a 6-character codeĤ. MIT RendezVous Server records the IP address of your PCģ. Your PC checks in with a 6-character code generated by the MIT AI2 CompanionĢ. The phone or table must be using Wi-Fi and not the cell network for Internet connectivity.
The MIT AI2 Companion allows users to make a connection between an Android or iOS device and a PC over the MIT RendezVous Server.
To use the AppInventor connection over Wi-Fi, a user must download the MIT AI2 Companion App via the Google Play Store or Apple App Store, and install it directly to your phone. How to get wifi/wlan working Is there a way to get it working yet As much as I'd like to use Qubes OS, without wifi it is. Below we explain in more detail how this process works. How does my Android or iOS device connect over Wi-Fi?Ī feature of AppInventor allows users to connect a device to a PC over Wi-Fi to test their apps.
