3 2) Installing the VPN software (detailed version) System Requirements You first need to check that your computer meets the minimum system and connection requirements: - Broadband Network Connection (If using BT Infinity check the Troubleshooting guide in section 4 first before proceeding) Operating systems Microsoft Windows o Windows 10 x86(32-bit) and x64(64-bit) o Windows 8.1 x86(32-bit) and x64(64-bit) o Windows 8 x86(32-bit) and x64(64-bit) o Windows 7 SP1 x86(32-bit) and x64(64-bit) o Cisco no longer supports AnyConnect releases for Windows XP. General Microsoft Windows Requirements: - o Pentium class processor or greater. o 100 MB hard disk space. o Microsoft Installer, version 3.1. o Upgrading to Windows 8.1 from any previous Windows release requires you to uninstall AnyConnect, and reinstall it after your Windows upgrade is complete. o Upgrading from Windows XP to any later Windows release requires a clean install since the Cisco AnyConnect Virtual Adapter is not preserved during the upgrade. Manually uninstall AnyConnect, upgrade Windows, then reinstall AnyConnect manually or via Web launch. o To start AnyConnect with Web launch, you must use the 32-bit version of Firefox 3.0+ and enable ActiveX or install Sun JRE Apple MAC OS o Mac OS X 10.9, 10.10, and General MAC OS X requirements: - o AnyConnect requires 50MB of hard disk space. o To operate correctly with Mac OS X, AnyConnect requires a minimum display resolution of 1024 by 640 pixels. 3

Connecting to the University via VPN To gain access to resources via VPN users will need an internet connection from home or any other location. For reliability issues we would recommend a wired connection. Once you have confirmed a usable internet connection you should open a web browser and go to which will present you with the main VPN page. NB We recommend using Internet Explorer or Edge (if using MS Windows) to install Anyconnect. Most other browsers are supported on MAC OSX and Linux but we would recommend Firefox. Step 1. Login page requesting users login credentials. 4

5 Select the either the Student or Staff group from the drop down box and enter your username and password in the username and password boxes. NB. Previously usernames were in the format of staff\username or student\username. This is no longer the case so staff \, student\ can be omitted and you can enter your username on its own (i.e. ab for Students or ab12 for Staff). After filling in the Group, Username and Password fields, select Login to proceed. Step 2. Once logged in you will be presented with the University Policy. NB. It is mandatory that you agree to terms and conditions of access. If you are unsure please visit for more information. 5

6 Select continue to go to the next step. Step 3. You are then prompted to Install ActiveX Controls as below figure shows if applicable. This is so that the correct version of AnyConnect is installed for your computer. Depending upon your web browser, you may have to follow the on-screen instructions for installing the ActiveX Control. Please see the troubleshooting section at the end of this document for help on this issue. Once computer detection has been determined, the client will proceed to install itself. 6

7 Step 4. A prompt will appear requesting you to install the AnyConnect client software on the machine. This will begin the automatic installation of the software. Select Install to continue. Step 5. This process can take up to 5 minutes depending on the speed of your internet connection. 7

8 Step 6. Once the AnyConnect client is downloaded, it will automatically establish a connection with the VPN service. You are now connected to Staffordshire University VPN system and can now continue to use University services. NB This is a one-time process to install the Cisco software. There will be a Start Menu (Windows Only) shortcut on your system that should be used to start Anyconnect. Should you move computers then you will need to repeat the above process to reinstall the client to access the service. 8

9 AnyConnect on a Client PC Connecting Once the AnyConnect client has been downloaded it will remain on the PC unless the user decides to uninstall it.
