Abstract

A boundary of a wireless network is monitored for incoming wireless signals that may interfere with an ability of a first wireless computing device to connect to the wireless network within the boundary of the wireless network. For an incoming wireless signal determined to interfere with the ability of the first wireless computing device to connect to the wireless network within the boundary of the wireless network, a directional opposing outgoing wireless signal is emitted to counteract the incoming wireless signal and to stop the incoming wireless signal from further interfering with the ability of the first wireless computing device to connect to the wireless network within the boundary of the wireless network.
