Data network management

In a network, such as WLAN, with many concurrent users, a wireless access point is configured with information relating to a set of priority devices (such as regular users) and when network utilisation exceeds a particular threshold (i.e. experiences congestion), the wireless access point is arranged to identify a priority device connected to the WLAN, determine a policy for reconfiguring (i.e. modifying band steering/QoS/access control) the WLAN to enable better performance to the priority device, and offer the improvements to the priority device. The changes to the WLAN are only applied if a user of the priority device opts to apply the changes (for example via e-mail or HTML page) thereby changing the WLAN performance in accordance with user requirements. The solution is concerned with modifying software of the access point, without/with minimal altering the configuration of the client devices.
