1. I Own It. No rental fee.
2. Took 1 five minute phone call to Comcast to setup. Just had to provide MAC address.
3. Works just fine with my CISCO Linksys E2000 Router.
4. Provides enough speed for 2 PCs, 2 smartphones, 1 iPad, and 2 Netbooks.


None so far. Everything has worked and is completely hassle free to setup and use.

Other Thoughts:

I had been renting a modem from Comcast that started randomly resetting itself sometimes every 10 minutes. After doing some research this modem seemed a good choice. It was up and running and is still running with no resets at all. Took 5 minutes to setup and I have had issues with it. Great Comcast modem replacement!
