Review: Recommend this seller highly - Works great no problem and was packed really well. It came in perfect condition for a refurbished item. Recommend this seller. The only thing negative is it took a lot longer to get than I wanted but it was still in the estimated time frame. It was roughly 3 weeks after ordering to delivery. But it was work it overall.
Review: SIMPLE SWAP WITH XFINITY - Cable has been acting up for a couple of weeks and I noticed the modem's light were flashing differently and intermittently. Ordered the modem and it came the SAME DAY!!! I just used the same power cord and Ethernet cable for the new modem. It took all of one minute. Turned it on and waited for all the 4 lights to turn green and the bottom one to turn amber. It took about 20 minutes.It did keep on resetting, but that was expected. Called Xfinity with the new MAC#. They reset everything. I then reset the router and I was back in business. Total time from beginning to end (including waiting on the phone with Xfinity) about an hour and a half. Now I have a good connection and the speed of the internet seems super fast now. The old modem was installed in 2017. I am extremely happy with purchase.

## Questions & Answers

**Q: Does this work with cable one internet provider?**
A: It works will all cable internet providers

**Q: Does it support mu/mimo?**
A: No, because this isn't a router with WiFi. 
This is just the cable modem, it converts the signal on the coax cable from Comcast (or whatever) to Ethernet. From there, you need a router with WiFi.

**Q: My internet is Mbps 1000 i have a netgear router this provider is fiber optic can you tell me if this is the right modem for me i have 4 tv's and a ga**
A: This is a Docsis protocol modem. It does not work with a fiber provider.
You should look into switching from the coax connector on the ONT (the fiber modem that your provider installed is the ONT) to the Ethernet port. The Ethernet port can supply a gigabit connection to your router, but the coax connection likely can't .

Please do some quick googling on this topic so you know exactly why you're asking what you're asking. It's confusing if you don't know what the terms mean.

**Q: Will this modem work with internet that comes through a phone line?**
A: this is a cable modem, not a dial up modem. Will not work with a phone line, nor will a phone line provide these kinds of speeds

### ⭐⭐⭐⭐⭐ Almost 1 year later!
*by T***S on September 1, 2024*

I ordered this back on October 4, 2023, its now September 1, 2024 so its been almost a year. I was a bit skeptical about how well this would do given some of the negative reviews and the fact that I bought it as a 'renewed' item. I replaced my old Arris Surfboard Docsis 3.0 modem and let me tell you this thing doubled my internet speeds. Its been a workhorse since then. The setup is super easy and it kinda just sets itself up for you. I've had to power cycle this thing several times whenever I see super slow speeds or Netflix isn't loading. Its the whole turn it off and back on again and that's the only thing I've ever had to do to fix any issues with speed. The last time I had to reboot it was probably over a month ago. I can't recommend this enough to anyone wanting to get a discounted, high quality item!
