Abstract: Techniques for establishing communication channels between user devices experiencing network connectivity issues and remote communication systems are described herein. The techniques include the use of a secondary device to act as a proxy, or a “middle man,” to facilitate the communications with the user device. A user device may detect lack of network connectivity, and begin broadcasting advertisement messages that indicate the lack of connectivity. A secondary device may detect the advertisement message, and send a discovery message to a connectivity system indicating that it detected the advertisement message. The connectivity system can provide this information to a remote communication system, and the remote communication system can establish a connection with the secondary device and instruct the secondary device to establish a connection with the user device. The remote communication system then has a communication channel with the user device, using the secondary device, to troubleshoot the user device.

Abstract: A softAP bridge is created to support a mesh network that also works seamlessly with any home Wi-Fi AP routers by using Layer-3 techniques to simulate a Layer-2 bridge. With this softAP bridge, Wi-Fi chipsets with integrated special Wi-Fi MAC Layer-2 mesh network support (e.g., 802.11s), or external gateway hubs, are not required. To accomplish this solution, one of the wireless devices may be designated as a relay device for communicating IPv6 data packets between a home AP router and the remaining wireless devices designated as client devices.

Abstract: Devices, systems and methods are disclosed for enabling a device to act as a wireless extender and adaptively control a transmission power for capability messages. For example, when the device has the capability to relay traffic without affecting a local processing of the device, the device may transmit capability messages at a normal transmission power and may relay traffic between a network device and clients. However, when the device no longer has the capability to relay traffic without affecting the local processing, the device may transmit capability messages at a reduced transmission power. As clients use the capability messages to determine a signal strength of an access point, the reduced transmission power results in the device appearing to have a lower signal strength and thus decreases a desirability of the device as an access point.
