Wi-Fi Services--Wi-Fi connectivity issue in High Density Wi-Fi locations
IT Services have identified an issue with some Windows laptops being unable to connect to College Wi-Fi services in certain High Density Wi-Fi locations around College. If affected then you may find that when you are in one of these High Density locations Windows displays a message ‘No Internet Access’ or you may experience limited internet connectivity with no web pages displaying.
This issue affects a small number of Windows laptops once they start using a wireless encryption setting called 'WPA2 Enterprise'. This WPA2 Enterprise setting is required to allow devices to connect more securely and at higher speeds to the College Wi-Fi services. IT Services are currently deploying new wireless access points which take advantage of the higher speeds in some locations but the issue identified means that some laptops cannot connect to these newer access points without intervention. This issue has been reported by other institutions using High Density Wi-Fi and usually affects devices running Windows and that have Broadcom wireless network adapters.
If you believe you are experiencing the issues outlined above then please follow the instructions below to update the driver software for your wireless network adapter.
