What is this triangle wireless connection in Windows 8?

Question

I just saw this connection show up in my wireless network list in Windows 8.

Answer 1

It's about the ad-hoc wireless connections:

A wireless ad hoc network is a decentralized type of wireless network. The network is ad hoc because it does not rely on a preexisting infrastructure, such as routers in wired networks or access points in managed (infrastructure) wireless networks. Instead, each node participates in routing by forwarding data for other nodes, and so the determination of which nodes forward data is made dynamically based on the network connectivity. In addition to the classic routing, ad hoc networks can use flooding for forwarding the data.

Answer 2

Yeah basically its an ad-hoc network. What that means is that you are directly connected to someones PC via wireless, as opposed to the ordinary method where you would both connect to a Wireless Access Point.
