Good thing you don't want WiFi!!
Yes, you can connect to Comcast.
SAM-SUNG has sung his last tune for me!
Samsung Model UN32J5500: after two months I can no longer connect to my wireless network. I have 13 devices in the house that CAN connect to any of my 3 networks, but not my Samsung.
Search the internet and you will read PLENTY of users with the exact same issue. The TV sits next to me at my home office, and my computer and phone are both on wifi but not my Samsung. SMART HUB is not so smart! As far as brands, choose any other.
