Wifi unavailable in the William Gates Building
  • Resolved
    UTC
    Resolved

    We believe that (with the exception of the Robotics-CL and govroam networks, as previously mentioned) the wifi service has been fully restored. Please contact service-desk@cst.cam.ac.uk if you are still experiencing any issues. We regret the unexpected disruption.

  • Update
    UTC
    Update

    Fixing the UniOfCam-Guest network will require us to withdraw the Robotics-CL and govroam networks which we believe not to be in use currently. The new software platform for our wifi infrastructure is unexpectedly limited to 6 networks (SSIDs). Please contact service-desk@cst.cam.ac.uk if you are relying on either Robotics-CL or govroam networks.

    Monitoring

    We believe wifi is fully operational again, except for UniOfCam-Guest. We continue to work with UIS on this.

  • Update
    UTC
    Update

    As service starts to be restored, you may find that eduroam starts working before Internal-CL or wgb. If you are seeing our networks listed but are struggling to connect, try selecting eduroam.

  • Update
    UTC
    Update

    Progress is being made towards a solution. We have implemented an emergency fix for two issues which unexpectedly caused UIS's new wifi setup to be incompatible with our existing departmental network configuration. We understand that UIS are still working on some other problems preventing wifi from functioning. We have no ETA at present for a resolution of those.

    Wired ethernet connections are, as ever, available throughout the building upon request to service-desk@cst.cam.ac.uk.

    Statement from UIS:

    The work scheduled to take place this morning to migrate access points (APs) on the West Cambridge site is overrunning. We had hoped to complete the work between 06:00 and 09:00 but have unfortunately not been able to complete the work in this timeframe. We are working to complete as soon as we can and will update this message when complete. We're sorry for any inconvenience caused by this delay.

  • Identified

    Identified

    We are aware of a loss of wifi in the William Gates Building. This is probably due to UIS's planned wifi infrastructure upgrades across the West Cambridge Site today; however we were not expecting a widespread and extended outage. We are awaiting further information from UIS.
