Always start here, using another Wi-Fi client to determine which is the likely culprit, the network or the client.
If multiple clients are unable to connect, follow instructions in our wireless network troubleshooting tip to debug probably AP or router or upstream network problems.
UITS recommends that you specify a certificate authority (CA) certificate for IU Secure connections to provide an additional layer of security to your wireless device; for help, see Validating the connection below.
Optionally, depending on your Android version, you can select either Validating your IU Secure wireless connection adds an additional layer of security and ensures the authenticity of an IU Secure wireless access point.
The list of trusted root certification authorities is built from the trusted root CAs that are installed in the computer and in the user certificate stores.
Abstract This article describes the tools used to troubleshoot a Microsoft Windows XP or Windows Server 2003-based wireless client, a wireless access point (AP), and the Internet Authentication Service (IAS) when using Institute of Electrical and Electronic Engineers (IEEE) 802.1X authentication for IEEE 802.11-based wireless connections.
When you deploy both PEAP and EAP (which is not protected), do not use the same authentication type.
For example, if you deploy PEAP-TLS, do not also deploy EAP-TLS.
If server authentication does not occur, users are exposed to severe security risks, including the possibility that users might unknowingly connect to a rogue network.
You must type the name exactly as it appears in the Subject field of each RADIUS server certificate, or use regular expressions to specify the server name.
You can validate your connection by specifying a CA certificate.
