The following screenshots/instructions were written for Ubuntu 14.04, but should require little or no modification for any Linux computer which uses Network Manager.
Collecting your token
To connect a personal device to ChemNet you will need some ChemNet credentials (ChemNet identifier and ChemNet token). You can get your personal token from https://apps.ch.cam.ac.uk/ssms/collectchemnet if you know your Raven password and are registered in the department database. If instead you want to connect a shared device (eg a lab computer) to the network please get your group computer rep to register the device.
