Upgrading my Cable Modem to DOCSIS 3.0 SB6141
This is both a question and gives information on how to save some bucks and a grip about cable company price gouging.
Suddenlink keeps calling me trying to sell me an internet speed upgrade. I already have 100 Mb download 10Mb upload with a 350GB download limit.
I have no issues with the speed. But I'm starting to hit my download limit every month. I know my usage has gone up with the addition of an Apple TV, Netflix and HBO now.
BTW. Instead of getting premier services like HBO from them, I did it through iTunes. You get three hook ups, so if I buy HBO Now, I can have it and also set it up at my girlfriends, she buys Netflix and shares it with me. It's about three dollars cheaper than the cable company but I can also have it on my iPhone and iPad,
So I checked and naturally I have to get a better faster cable modem, a DOCSIS 3.0 Cable Modem. The cable company will rent this to me for $10 a month, (a ARRIS SURFboard SB6121 with 4X faster speed or I can buy one outright new for $70.00. I bought one off eBay for $40.00 one step up from what the cable company was offering. A SB6141 Surfboard modem with 8X faster speed.
My question is, can I just install it or do I need to register it with the cable company, then upgrade my plan?.
