WiFi Setup: "Brown" on Linux

The Brown secure wireless network may not work correctly with Ubuntu and some other Linux distributions out of the box. These issues are caused by an SSL certificate verification failure.

  • Wireless Network Name (SSID): Brown
  • Security Type: WPA2-Enterprise
  • Encryption Type: AES (CCMP)
  • EAP Method: PEAP
  • Phase 2 (Inner Method): EAP-MSCHAPV2
  • Root CA Certificate(s): AddTrust_External_Root.crt
  • User Certificate: N/A
  • Anonymous Identity (Outer Identity): [Leave blank]
  • Username (Identity): [Your Brown Username]
  • Password: [Your Password]
