I recently set up a new account with Comcast. I set up the new cable modem I got and it's currently connected to an old laptop I plan to donate to Goodwill. My roommate and I both have laptops equipped with wireless cards and we want to be able to roam around our apartment while using the Internet. The modem does not come with a wireless router so I am looking into getting one. However, from past experience, the modem is connected to the router with an ethernet cable and the router is connected to a computer, generally a desktop. I will not have a third computer for long. Is it possible to have the wireless router be connected to the modem and still share any internet connection?
