Ad Hoc network is a group of PCs installed with wireless LAN cards, this group of PCs is called a BSS (Basic Service Set). PCs in this group can use their wireless LAN cards to communicate with each other, but can not connect to the Internet. The most obvious difference between Infrastructure wireless network and Ad Hoc 24 wireless network is that the PCs in Infrastructure wireless network can access the resource in the Internet through Access Point. Depending on your requirement, you can easily set up your PC's network to be a "Ad Hoc" or "Infrastructure" wireless network. Generally speaking, if in your network, there is an Access Point in it, we recommend you to set your network as an "Infrastructure", so it can connect to the Internet.
