Which modems are compatible with comcast

Great site! Very informative but was hoping someone could give me some guidance. Then about 14 months ago I bought a Motorola MT and saved on the monthly modem rental. Customers are also complaining about the quality of my VOIP business phone calls. I called Comcast and they said they could not see my modem from their end.

Then they sent a technician and all he did was verify all the connections were snug. Cable TV works fine never any problems. I told him I would take speed but every internet speed test I ran on my computer showed I was getting between 10 and tops. So what am I supposed to do? Does anyone want to weigh in? You are correct, Michael, you should be seeing about Mbps internet speed. You will need a separate router if needed.

You could try a faster modem listed above, but something is not right with your service. Your current modem should be providing faster speeds than what you are receiving.

You could try swapping out any cable splitters you are using. Hi, is the CMV know to have Broadcom chips? What is basis that it does not have the Puma bugged chips? I am looking to get one after losing a CMV, and I want to confirm its chips. Netgear support was no help. It is assumed the CMV is using a Broadcom chipset, because there have not been any mass complaints of latency issues with the modem. Both use Broadcom chipsets S33 proof and MB proof.

Motorola Zoom has stated they do not use Intel Puma chipsets in any of their modems. You can then combine your modem with an Ooma device free calling — cheaper service for you. When we started working from home this summer, we were having a lot of internet issues so we called Comcast and upgraded our Internet, Phone and TV package. The new bundle gave us MBPS however, we were continuing to have issues so we called Comcast again and they told us we need to upgrade our equipment to Docsis 3.

So out of frustration and really stuck on what to do, tonight I ordered the Arris Surfboard T Thank you to anyone that can provide some assistance!!!! Question — If I have a separate cable modem and WiFi router, each with ethernet ports, which is the preferred device to plug in an ethernet cable from a smart TV? If your cable modem only has one ethernet port, that should be connected to your WiFi router already.

So, Kevin, using one of your ethernet ports on your WiFi router is the way to go as long as it is giving you a fast enough speed to stream a movie or game online. If not, then you would need to use your modem ethernet connection. All I need is a modem for xfinity land line phone service. Pat, your options are limited. What modem can we buy that will work for us? When we have family visit us sometimes there are 2 to 3 laptops on at the same time plus cell phones using the internet. We are not tech savvy at all.

If you already have a router and just need a modem, then the Motorola MB is the best option. Dave G. My computer speed is mbs. Will any of these work and can I hook it up myself. Yes, Dave, all of those devices will work. The other two options would be nice devices for you. These modems are easy to hook-up. Will I be able to change this setting on the Motorola modem? I would like to use a different DNS for privacy.

Also any thoughts on this product would be appreciated. Sorry, Peter, you need to contact Motorola for a definitive answer to your question about changing the DNS setting. Motorola lists a few modem models with the ability to set static DNS , but does not include the MT Perhaps Comcast blocks this setting due to the device being a phone modem. The MT is a solid device if you are not planning to go with 1 Gig speeds in the future, Peter. Yes, it is, A. I received an email from Comcast saying they have upgraded my speed from mbps to mbps.

No charge but my current modem is too slow for the mbps. This is what got me to find your website. I see the info about the bad Intel chipset. My laptop is 9 years old. This happens every day. I looked to see what other modem I could purchase but we need modem, wifi, and telephone. Comcast list just has this same modem or two others: Motorola MT up to mbps and also Netgear CV up to mbps. As an FYI- it is just two of us in the house so no more than two devices on at a time. Just did a speedtest and Ping is 17ms, download At some point you will go from Mbps to Mbps with the next free upgrade.

Then you can combine the modem with a stand-alone router. Another option, Richard, is to eliminate the phone service from Comcast and purchase an Ooma device ; it offers phone service to your home by using your internet connection. Your laptop may also need an upgraded WiFi adapter to handle these faster speeds if you are using a wireless connection to the PC.

I cant believe that it is no longer going to work on Comcast. What is going on here?? Comcast over the last year has begun removing slower modems like 4-channel and 8-channel download devices from their approved modem list. So, I did. Seller subsequently contacted Xfinity and was told that the modem is nowhere listed on his account.

That Xfinity agent also told him to call Netgear to have them reset the modem as it was already used in another Xfinity account before so that it can be used in another account. Seller confirmed CMV was last used on Xfinity 5 months ago. Have you heard of that need before to be able to successfully activate a CMV or any modem previously used on Xfinity?

Doing a factory reset is a local action on the CMV. That sounds utterly inefficient and seems unnecessary? Buying used modems is not a good idea for this exact reason. Plus, used electronics can be a fire hazard because you have no idea what the previous user or users did to the modem. The suggestion is to return it to the seller, because you can not activate it and purchase a brand new modem. Yes, it will cost more, but you will at least know the condition of the device and it should activate with little trouble.

The previous user may have switched internet providers or passed away or a the internet provider makes a human mistake, etc. Unfortunately, purchasing a used modem involves risk, Kei. So we will need a modem wifi router that will work for us but not sure which one will work. Your best value option will be the Motorola MG modem router combo unit.

The device is capable of wired speeds up to around Mbps, so your son will have room to grow when he upgrades his speed in the future. I just checked, that a Docsis 3.

Please advise. Would the Netgear CAX30 be my next best bet? A few more but hopefully better. While the price increases, you do gain some valuable upgrades. The device can handle speed plans up to 2 Gbps no need to upgrade the modem in the near future. WiFi 6 is backwards compatible with WiFi 5, so if your son is currently only using WiFi 5 devices, everything will still work. I have Comcast Business and needed phone services.

The MT is on the supported devices list. I spoke to three different reps and none of them was able to activate my modem. They all said model MT is not on their list. Perhaps business and residential are different.

The approved modem list above is for residential, although residential and business modems are usually the same lists.

Unfortunately, Andy, Comcast Business does not allow you you to use your own device for voice services. You will need to rent a device from Comcast Business for phone capabilities. Hello, I have some questions.

The lights would recycle on it like in a continuous reboot loop. Is that because of the firmware not being able to be updated?

Should I get docsis 3. Thanks in advance! If you already have a device active, it will still work for sometime. Your modem may have experienced an electrical surge or just finally gave out. Adding a router to that doubles the cost. Maybe that is two years. A recommendation for you, the Motorola MG If you want to go the cheaper route, you purchase a separate router and modem.

You will likely have better performance from a separate router anyway, as opposed to a integrated router. When talking about channel bonding, the first number refers to the number of channels available for downloading data. The second number refers to how many channels are available for uploading data. For example, a cable modem with 8x4 channel bonding features eight download channels and four upload channels.

This modem should support an internet plan with up to Mbps download speeds. So look for a modem with just enough channel bonding to support the internet speed advertised in your plan. Your Xfinity internet plan comes with a promised maximum download speed.

For example, the Performance Select plan comes with a promised max speed of Mbps. Another way to check what speed your internet plan comes with is to run a speed test. This gives you a more accurate view of what speeds you actually get. We recommend running several speed tests over the course of the day to get a bigger picture of how much your speed fluctuates at different times.

You could spend almost the same amount for just a modem. So the C might save you more money in the long run. The router also comes with excellent features like beamforming, which directs your Wi-Fi signal to your devices. Think of it like lining up for a slam dunk versus blindly throwing 20 balls in every direction and hoping for a basket.

Granted, all those features cost a pretty penny. Our pick for the best Xfinity-compatible cable modem is the Motorola MB, thanks to its low price and support for wired speeds up to 1, Mbps.
