At my college the Wi-Fi uses WPA2 Enterprise to secure the connection. I log in with a username and password. My phone (LG Optimus Elite, Android 2.3.7) successfully connects to the network, and I can use it for an arbitrary amount of time before the phone suddenly crashes and reboots. I've successfully used the phone on other wireless networks, so i know that's not the problem.
The specific configuration of the network is below (per the university's directions)
EAP method: PEAP Phase 2 Authentication: MSCHAPV2 CA Certificate: unspecified User certificate: unspecified Identity: MyUserName Anonymous Identity: Blank Password: MyPassword
Edit: Common times when phone crashes (only on university Wi-Fi, never any other time)
