Slick Dealers don't rent from Xfinity. Slick Dealers buy a modem and router. Bite the bullet and buy. Don't rent.

I've been running one with zero downtime and consistently great speeds for 6 months now. Highly recommend this.

I've had this modem with Xfinity gigabit internet service for 6 months with no issues so far. It has been solid.

This modem is probably fine, but I didn't realize it didn't come with built in wifi. Don't buy this if you need wifi.

What you're looking for is often referred to as a wireless gateway, not a modem. This is a good modem, but it is a modem only, and doesn't have any built in routing, switching, or wireless access point capabilities. Quick explanation here [minim.com].

Really? I need uncapped data limits, and for me it's cheaper to bundle that with a rented XB7 than use my own. My customer-owned modem is sitting in a closet.
Same here. Plus is you want VOIP like Ooma, theXfinity gateway includes that as a plugin.

When renting the modem gives you unlimited data for cheaper than the price of adding unlimited data, then renting is indeed a Slick Deal.

Is this worth it to avoid $12 monthly model rental charge ?

This is 170 and tax so about 185
It would take 15.5 months to break even.

For optimum
If all of the following for you are true:
  1. There is a new modem or new modem technology that comes out every two year,
  2. You are the type of person that will buy the newest modem every two years,
  3. Your $12 rental charge will give you the newest modem every two year,
If all of the above are true for you, then no, buying this modem will not be worth it for you and renting will be better.

Alternatively, if you plan to stop using cable internet in 16 months and after that will no longer need a cable modem, then yes renting will also be better for you in this situation.

Thanks but I assume this is very high end modem and I could use something cheaper as an alternative

Is this overkill for a regular home spectrum connection so I don't have to rent their modem? Just casual internet and streaming tv. I have separate wifi router. If not, anyone have a good cheap recommendation?

All these high end routers are useless when cable internet companies are limiting upload speed to 5 or 10 mbs only.

Buy a used cable modem for $20. Even Xfinity 400mbs plan only gives you upload speed of 10mbs.

I've had an SB8200 for a few years now. Comcast tells me I have up to 1.2Gbps down but I've never seen it. I test on Ookla, speedof.me, and the Xfinity app and it bounces between a reported 400Mbps to 840Mbps. This is on a *wired* connection through an ASUS RT-AC68R router.

Would this modem increase my throughput? If not, any comments on how to get above 840 Mbps on a purported 1.2 Gbps line?

TIA.

800-950Mb/s is about what you should expect from your setup under ideal conditions, so 840Mbs isn't surprising.

Your ISP providing a 1.2Gbs connection doesn't necessarily mean you will be able to see that speed on a single client. With your current setup, everything you have is connected at 'only' 1Gb/s, so it will be impossible for you to see anything above that. Your modem has a 1Gb/s connection to your ISP (because it only has a 1Gb port). Your router has a 1Gb/s connection to the modem (because the modem and router only have 1Gb ports). Your computer has a 1Gb/s connection to the router/switch (because the router and [I'm assuming] computer only have 1Gb ports).

Think of it this way: just because you have a 100A electrical service at your house doesn't mean you can just plug something in to an outlet in the bathroom and pull 100A. You would need to have the proper panel/subpanel, breaker, receptacle, and cable connecting everything.

If you want to be able to pull 1.2Gb/s from your ISP (split among all of your connected devices), you will need to upgrade both your modem and router. If you want to see 1.2Gbs from a single client (like you were trying to test), you will need to upgrade the modem, router, and the Ethernet adapter in the client.
