Known Issues

  • Google Android Gingerbread 2.3.6: We are aware of an issue with Gingerbread 2.3.6 and Phase 2 Authentication. This will prevent successful authentication on the eduroam service. This appears to be a known issue as a patch is available for Samsung devices via Kies ». This is reported to fix the issue on the Samsung Galaxy Y. For users of none-Samsung devices, please refer to the manufacturer for an update.
  • Google Android Wireless Roaming Issue: There is a known issue with Google Android devices roaming on a Enterprise WPA2 infrastructure, which is what eduroam is based on. i.e. when moving from one location to another you will be disconnected from eduroam. The only know solution is to turn off/ on Wi-Fi and if this fails Forget the eduroam Wi-Fi and re-configure.
  • Google Android 2.2: There is a known bug with 2.2.x Android phones that may prevent automatic connection to eduroam » It is expected that 2.3.3 (Gingerbread) will fix this issue.  A temporary workaround to this bug is to toggle wireless off and on again. It has also been reported that Juice Defender will do this automatically (this is useful if your manufacturer will not issue an OS update).
