connect two computer

Without an Internet connection, you can’t use syncing services like Dropbox to share data between devices easily. If you have a networking device like a router, hub or switch, you can get the connect two computer to each other, but it requires quite a bit of additional work (file sharing, permissions, firewall configurations, etc).

if you have a laptop or computer that has a wireless card and so does your buddy, you can use the cards to make a wireless connection between the two computers. Once they are connected wirelessly (also called a peer-to-peer ad-hoc wireless network), you can easily share data between the computers.

You can create an ad-hoc network in Windows or in OS X and in this article I’ll explain the steps for creating the network for each OS. It’s important to note that ad-hoc networks in general have certain limitations that make them only useful for certain situations. Firstly, the speed of an ad-hoc network is normally less than that of a normal infrastructure network. Ad-hoc network specs only require a max speed of 11Mbps, which is way slower than b/g/n/ac max speeds.

Secondly, you can’t monitor signal strength of ad-hoc networks, so you have to make sure the computers are fairly close to each other and don’t move around a lot. Lastly, ad-hoc networks don’t support all the security features of normal infrastructure networks, so they can be more easily hacked.
