Using Air Sketch with an Ad-Hoc network (no hotspot needed)

Several users have asked if its possible to use Air Sketch when a WiFi hotspot isn’t available. It turns out the answer is YES! Air Sketch works just as well when connected directly to a computer running an Ad-Hoc network.

An Ad-hoc network is basically a private WiFi hotspot that runs off your notebook or desktop computer. All modern operating systems allow you to create one very easily in a couple minutes. This can be very useful when you are in a WiFi-less environment, or don’t want to risk connectivity issues on an unfamiliar network.

Here’s how to use Air Sketch on an ad-hoc network with Mac OSX Snow Leopard:


1. Start on the Mac. Click on the Airport (WiFi) icon in the menu bar and select "Create Network...". Give it a name, and (highly recommended) a password.

2. Go to network settings on your iPad, and join that new network. Wait for the WiFi icon to appear in the status bar. We found that it can take up a minute for the ad-hoc WiFi connection to be established.

3. Now launch Air Sketch. The IP address will be different, but everything else should work the same.


That’s it! On the first connection it may be necessary to manually refresh the browser a couple of times if the network hasn’t been fully established yet.

The steps for other operating systems should be very similar. Here are the steps for setting up an ad-hoc network on Windows Vista and Windows 7. Note that you can’t set up an ad-hoc network from the iPad itself.


But wait, there’s more!

Once you have your ad-hoc network set up, additional devices can connect to it and to Air Sketch as well, just like any other WiFi hotspot. You can even connect your iPhone, another iPad, or iPod Touch to the network and project Air Sketch to those. Before you go too crazy on this, remember to limit the number of Air Sketch clients (we recommend less than 4) to avoid performance issues.
