A method of managing a wireless access point device having a local network interface (231, 233) for wireless and wired connections via a respective wireless network and wired network, and an interface to remote networks, the wireless access point being connected, via the local network interface (231, 233), to at least one cellular network base station device for providing cellular network connectivity to cellular network devices, the method comprising: at the wireless access point: monitoring characteristics of flows of data of packets travelling between the at least one cellular network base station device and a remote resource located on a remote network, determining, based on the monitored characteristics, whether said at least one cellular network base station device is an interference device which can affect a wireless network environment of the wireless access point; in response to a determination that an interference device is present: listening for a second wireless network associated with a second wireless access point; and if a second wireless access point is present, measuring characteristics of said second wireless network; sending a message to an interference management server, said message containing information relating to the interference device and the measurement characteristics of said second wireless network; at the interference management server: sending instructions to alter a configuration of the wireless access point in response to a determination that an interference device is present; and sending instructions to alter a configuration of the second wireless access point. at the wireless access point: monitoring characteristics of flows of data of packets travelling between the at least one cellular network base station device and a remote resource located on a remote network, determining, based on the monitored characteristics, whether said at least one cellular network base station device is an interference device which can affect a wireless network environment of the wireless access point; in response to a determination that an interference device is present: listening for a second wireless network associated with a second wireless access point; and if a second wireless access point is present, measuring characteristics of said second wireless network; sending a message to an interference management server, said message containing information relating to the interference device and the measurement characteristics of said second wireless network; monitoring characteristics of flows of data of packets travelling between the at least one cellular network base station device and a remote resource located on a remote network, determining, based on the monitored characteristics, whether said at least one cellular network base station device is an interference device which can affect a wireless network environment of the wireless access point; in response to a determination that an interference device is present: listening for a second wireless network associated with a second wireless access point; and if a second wireless access point is present, measuring characteristics of said second wireless network; sending a message to an interference management server, said message containing information relating to the interference device and the measurement characteristics of said second wireless network; at the interference management server: sending instructions to alter a configuration of the wireless access point in response to a determination that an interference device is present; and sending instructions to alter a configuration of the second wireless access point. sending instructions to alter a configuration of the wireless access point in response to a determination that an interference device is present; and sending instructions to alter a configuration of the second wireless access point.
