Techniques for monitoring presence of a remote device at Layer 2 that allow reducing power consumption without compromising the device's availability. A device that pairs with a remote wireless device may establish a Layer 3 connection, such as an IP connection, to the remote device to provide services to a user. The Layer 3 connection may be formed over a Layer 2 connection via an access point or as a peer-to-peer wireless connection between the devices. When the Layer 3 connection is not actively used to access the remote device, the Layer 3 connection and the supporting Layer 2 connection (e.g., WI-FI, WI-FI DIRECT&#x2122; or BLUETOOTH&#xae;) may be terminated and presence of the remote device may be monitored using a Layer 2 device discovery mechanism. The Layer 2 and Layer 3 connections to the device may be reestablished when use of the remote device is desired.
