Is D-link a good router?
The Good. D-Link Wireless N Router DIR-615 offers decent Wireless-N performance at a very affordable price. It also has a responsive and intuitive Web interface.
What connection type does Comcast use?
Basic Connectivity. Generally, the basic setup is that your Comcast coax cable gets screwed into the F-Type connector on the DOCSIS modem. Unless you're forced to rent this, the far cheaper, and more secure, option is to buy your own (new) modem.
