FIRST: You will need a Gmail Account. Sign up HERE.
Before hanging out for the first time, there are a few things you'll want to do:
If you don't already have it, download Google Chrome Browser...Click Here to download.
Download and install the latest version of the plugin.
You will need a webcam. Make sure you have the latest drivers for your webcam. Remember sometimes your audio will come for an external webcam.
Connect to your router or modem by using a Cat 5 cable. This will improve the visual and audio. See below video.
Check your Internet connection speed using http://InternetFrog.com to test (for example my numbers for Comcast's medium level of service are about 35Mbps down and 5Mbps up. with a 65ms round trip time)
For the best video quality, make sure you're well lit from a light source that's coming from behind your camera.Webcams don't work well in low light situations.
Go the checkerboard icon on the top right. Click on it and look for profile.
Establish your profile to include uploading your picture.
Shut down extra browser windows or programs behind you, e.g., FaceBook, etc
Connect your head set to your device! Headphones with a built in microphone will dramatically improve your Hangout experience or use earbuds to control sound.
