SB6141 Modem End of Life?

[So after one year with Xfinity, I renewed my contact and finally decide that it was time to purchase my own modem/router. I purchased the Arris SB6141 (Modem) and Asus RT-N66U. I called customer support gave them my MAC ID, when I was prompted to and waited for them to connect my modem then hooked it up to my router. All seemed fine for I was able to configure my router, then I disconnected from my internet. I reseted my modem, router, modem and router, multiple times. Then I called back CS, this time they try to reset the connection, still "no connection." Afterwards, I was told to switch modems and to plug in the modem/router that I was renting, received no connection at first, then I'm connected and all is fine. I ask the operator if I could find out why the new modem I purchased was not working (since I asked at a store if that particular model, SB6141, would work for my service plan when I renewed my plan). He said it was declard "End of Life" and that I should return it.]

 

One quick google search and I find this post: http://forums.xfinity.com/t5/Your-Home-Network/SB6121-6141-End-of-Life-Details/td-p/2708003

SB6121/6141 End of Life Details

"no longer supported by Comcast typically because of updates or changes in technology.

Customers who own their own SB6121 or SB6141 modems can continue using these models with their Internet services. The only versions of SB6121 and SB6141 being declared End of Life are modems being leased from Comcast."

 

This states that those "who own" (the category I fall into) can continue their services with, but I was told that the SB6141 wouldn't work. So given this, should I return my modem and buy a new one, or try again knowing that it'll likely be a waste of an hour or so. 

If I buy a modem, anyone got a recommendation for a fairly recent Comcast approved modem that pairs well with the ASUS RT-N66U.

FWIW, personally, I would not invest in a DOCSIS 3 modem at this point with the new DOCSIS 3.1 spec right around the corner and already upgraded in some areas. I would get a DOCSIS 3.1 capable modem like these;

The 3.1 modems remain backwards compatible with yet to be upgraded 3.0 systems.
