I need to purchase a cable modem so i can stop my 10$ monthly charge from comcast! Here is what i currently know about the modem im currently renting from comcast..... It is pretty good, no complaints, its a XB3 with up to 32 channels DOWN, and up to 8 channels UP. Has built in WIreless AC 5ghz, and it actually works just fine, just wanting to purchase my own so i can avoid this 10$ charge. My current internet speed is 180Mbps DOWN, and 30Mbps UP using 24channels DOWN and 4 channels UP.... HOWEVER in 6 months when this speed package is over, i am gonna take on their 1Gbps internet speeds so I will need a 32ch DOWN 8 ch UP modem. What modem would you recommend that would be "Plug and Play" with Xfinity Internet and offer at least Docsis 3.0 (Or greater) with or without built in Wireless AC? Really appreciate any feedback. Thanks

I was in exactly the same situation as you, but I also have Comcast Voice, which limited my choice of cable modems. I ended up with an ArrisTM 822R Wireless Gateway, which I got from Amazon. I also bought the backup battery from a third-party.

Once I had the modem plugged in, I called up Comcast. Once I got past the annoying voicemail system, I talked to a first-level support person, who promptly switched me to a specialist. She was very, very helpful and very encouraging. (I wish all support people were this nice. :woot: ) Not 20 minutes later, my WiFi router had connected my laptop to the Internet. I know people like to dump on Comcast, but their support consistently is better than that. :geek: (y)

We have almost the exact same plan as you and wanted to do the same thing as I couldn't get my vpn router to work behind the comcast gateway without turning it into just a plain modem.

We got the sb6190--even though people swear up and down this modem has 'puma' problems (check out dslreports)--we have had no issues and get our rated speeds without issue. Because of the 'puma issue' people unreasonably dump these modems too, so you should be able to find one nearly brand new for under $50. We coupled this with an Archer C5 to use as an access point and have been very happy with the combo.

The gigabit service currently requires their equipment, so I'd hold off on buying anything that might be able to be used and just get what they need if that time comes. You can always sell your existing modem and recoup some of your cost (and you're still ahead $10xNumber of months).
 
Puma has nothing to do with getting rated speeds FYI. It's about latency issues and packet loss. You can easily peg any speed meter, but if you're doing something that is latency sensitive (like gaming) you'll probably notice hiccups while playing games because the modem is dropping traffic or causing delays.

If you just want a modem then the SB8200 would be a good pick as well.

Wow, you're getting wireless from your TM822R?

Not a bad product, I use one myself, but definitely not a Wi-Fi gateway. For the speeds the OP wants, if he wants a wi-fi gateway, he'll want a D3.1 for best service. Looks like Netgear has one available. I understand ARRIS will be coming out with one early next year. I personally think separate modems and routers are the way to go, so I'd invest in the ARRIS SB8200 myself in this situation.

No, I don't get my wireless from the Arris unit. For that I have a TP-Link Archer C9 wireless router. AC1900 speeds, fast enough for me.

Well, you did call it a wireless gateway. I can't tell you how many people I have had to work hard to convince that they are not getting Wi-Fi from their cable modems. We're the manufacturer for goodness sake! You'd think they'd believe us when we tell them what our products can and can't do!

They are also open to DOS attacks due to their design problems.

I use remote desktop all day long which is very, very sensitive to any type of latency, and I have none other than the trivial hiccup. Completely usable and completely stable.
