Technical Examples

A system and method for wireless network communications provides a "dual-mode" wireless device that operates concurrently as a member of two disjoint wireless networks, such as an infrastructure ("IS") network and an ad hoc ("AH") network. The dual-mode device has a wireless controller driver inserted in its networking stack (e.g., the stack comprising of the Network and NDIS drivers) that exposes two virtual wireless network adapters, one for the first wireless network and one for the second wireless network. Each virtual wireless network adapter has an associated queue for queuing packets in the flow for the corresponding wireless network mode. The wireless controller driver controls the switching of the network mode. In one embodiment where the two networks include an IS network and an AH network, the mode switching is triggered by poll signals transmitted by an access point of the IS network. When the mode is switched from operating in the first network to operating in the second network, the first virtual network adapter is disabled and the second virtual network adapter is enabled, and the queued packets in the queue for the second virtual network adapter are transmitted over the second wireless network.
