I am installing my modem myself. How much time do I have to complete the installation?

You choose when to start the installation. You won't need more than half an hour to complete the installation, so no need to leave that box in the garage for weeks. ;-) You don't start paying for your Internet connection until you've been able to successfully install your modem and your line is active. We check that, so you don't have to do anything at all for that.
