This article contains some tips on how one may want to troubleshoot network problems on an Android phone. If you are having trouble connecting to the WiFi network try the following the solutions.
Clear Security Certificates
Go to Settings, Select Security, Select Clear All Credentials. Re-connect to eduroam.
Reset WiFi Connection
The first thing to try if the network isn't working, is to Go to Settings, and turn off the WiFi, and then turn it back on. Sometimes, that's all it takes.
Restart Device
Sometimes the best thing to do when a feature isn't working to allow the device to reboot. To do this, power down the phone, and remove the battery. Wait about thirty seconds before putting the battery back in, and powering the device up. After it boots, retry connecting to eduroam.
Reconnect to eduroam
Try forgetting the network and then manually adding eduroam back onto network list. This can help by correcting any typo in login id, password, or incorrect settings that may be preventing connection. The following steps will show you how to do this:
1. Open Settings & tap Wi-Fi.
2. Under Wi-Fi networks you will see a list of available networks. Tap eduroam, if it is listed.
(NOTE: If you do not see eduroam, proceed to manual configuration)
3. In the pull down menu of 'EAP Method', select 'PEAP'.
4. In the pull down menu of 'Phase 2 authentication', select 'MSCHAPV2'.
5. Scroll past CA certificate and Client certificate. (In some phones we have found that setting these two options to N/A works)
6. In the 'Identity' field enter your [myLSU ID]. (Ex. mtiger1@lsu.edu)
NOTE: Enter your MyLSU credentials in the form <myLSU ID>@lsu.edu. If you do not do this, you WILL receive an error message.
7. Skip the 'Anonymous identity' field.
8. In the password field enter your myLSU password.
Note: If your cursor is stuck at 'Identity', click "next" on your keypad twice to get to 'Password'.
9. Tap Connect. The account settings, including username/password are now saved and you will connect automatically when eduroam is in range.
