This disclosure describes, in part, techniques and systems for enabling new devices introduced into respective environments ('provisionee devices') to be provisioned by existing devices in the respective environments (“provisioner devices”) in a manner in which the provisioning requests sent by the provisioner devices are allocated over time and, thus, do not overwhelm the provisioning system(s) at any given time.

Allocating requests

Techniques for establishing connections between user devices and headless devices attempting to connect to networks. A headless device may attempt to connect to an access point that requires interaction with a captive portal webpage for access to a network. However, the headless device my lack a display to present the captive portal webpage. The headless device may establish a connection with a user device using a PAN protocol. The headless device may then receive the captive portal webpage received from the access point, and relay the webpage to the user device using the PAN protocol. A user may use the user device to interact with the captive portal webpage, and the user device may then relay interaction data back to the headless device using the PAN protocol. The headless device may then provide that interaction data to the access point to be provided access to the network.

Establishing communication links to assist headless devices

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.

Establishing data channels between user devices and remote systems

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.

Software-enabled access point (SoftAP) based bridging of devices in two wireless networks

Technologies directed to determining a TCP throughput of one or more communication links between two or more devices of a LAN. One method includes a first device that generates a second data packet from a first data packet by modifying a destination address field to be the same as a source address field. The first device sends the second data packet to the second device and receives a third data packet in response. The third data packet specifies the address of the first device in a destination address field and a source address field. The first device generates a fourth data packet from the third data packet by modifying data in the source address field to specify the address of the second device and determines a first value indicative of TCP throughput of a first communication link between the first device and the second device.

Independent transport control protocol (TCP) throughput measurement on a client device

This disclosure describes, in part, techniques and systems for enabling new devices introduced into respective environments ('provisionee devices') to be provisioned by existing devices in the respective environments ('provisioner devices') in a manner in which the provisioning requests sent by the provisioner devices are allocated over time and, thus, do not overwhelm the provisioning system(s) at any given time.

Techniques for performing high-precision presence detection by establishing and monitoring peer-to-peer communication links between user devices residing in a same physical environment. A user device that resides in the environment may establish communication links with multiple other user devices residing in the environment. The user device may monitor the channel properties for those communication links to detect fluctuations in the channel properties caused by a user moving through a signal of the communication links. In examples where the user device detects fluctuations in channel properties for multiple communication links, the user device may determine that the user had moved though signals of the communication links. The user device may determine that, because the user moved through signals of multiple communication links, the user may be in close proximity to the user device, such as in the same room. Thus, the user device monitors multiple communication links to perform presence-detection techniques.

Proximity detection using device-to-device communication links

Technologies for cloud-based secure WLAN group self-forming are described. One provisioner portal device receives, from a client provisionee device that desires to connect to a home WLAN, a first SSID and forwards, to a cloud service via a wireless AP device, the first SSID and a MAC address. The provisioner portal device receives, from the cloud service via the WAP device, a second SSID and a passphrase. The provisioner portal device sends, to the client provisionee device, a response that includes the second SSID. The provisioner portal device creates a one-time provisioning wireless network with the second SSID and the passphrase. Through the provisioner portal device, WAP credentials can be exchanged from the cloud server to the client provisionee device over a secure channel. The WAP credentials can be used to switch to the home WLAN without user interaction to manually enter the WAP credentials at the client provisionee device.

Cloud-based secure wireless local area network (WLAN) group self-forming technologies

Techniques for connecting computing devices to a network are described. For example, a network access device (NAD) connects to a first network that includes a first access point (AP). The NAD receives, from a computing device, first data identifying a second network to be established for the computing device and sends the first data to a server. The NAD receives back a first credential associated with access to the second network and sets up a second AP to the second network. The second AP is associated with the first credential. The NAD sends, to the computing device, second data indicating that access to the second network is available, generates a second credential associated with access to the first network via the first AP, and sends the second credential to the computing device via the second AP.

Managing access of a computing device to a network

Techniques for providing a server-based Wi-Fi Protected Setup (WPS) PIN procedure are described. In an example, a computing device generates a PIN associated with a WPS-PIN procedure. The computing device encrypts the PIN to generate an encrypted PIN based on a public key associated with a server. Further, the computing device sends, to another computing device that is communicatively coupled with the server via an access point, a WPS probe request that includes the encrypted PIN. Based on the WPS probe request, the computing device receives, from at least one of the other computing devices or the server, a credential associated with the access point. The computing devices connects to the access point based on the credential.

Server-based Wi-Fi protected setup (WPS) PIN procedure

Devices and methods are provided for determining and establishing network path for a streaming video device. The device may receive video from a remote digital video recorder (DVR) through a first access point (AP) wirelessly connected to second AP of the remote DVR, wherein the streaming video device, the first AP, and the remote DVR share a network, wherein the remote DVR includes a third AP. The device may determine a first connection quality associated with a first frequency band between the streaming video device and the first AP. The device may determine a second connection quality associated with a second frequency band between the streaming video device and the second AP. The device may determine that the second connection quality exceeds the first connection quality. The device may establish a direct connection between the streaming video device and the second AP using second frequency band. The device may receive DVR video over the second frequency band.

Network routing selections for wireless devices

A first device transmits network-login information corresponding to a network to a first device, thereby permitting the first device to join the network. A discovery request from a second device is received; the discovery request includes identification information corresponding to the second device. The first device outputs output audio corresponding to the identification information and optionally receives a confirmation from the user.
