    5.0 out of 5 stars For X-Finity/Comcast customers... easy install, excellent performance, great price.
    Reviewed in the United States on December 18, 2024
    This modem is on the Xfinity approved replacement modem list and gives me identical speeds to the X-Fi gateway both directions, upload and download. The installation was ridiculously easy to do with zero interaction with the Comcast support team. Just have a cell phone ready, download the Xfinity app, follow the supplied directions and if you get lucky like I did, the whole process will take about 5 minutes.

    This particular modem model, the "Hitron Coda56", does not give you telephony jacks like the x-fi gateway does and it comes with no built-in Wi-Fi router and only a single "out" ethernet plug. If you have a router with Wi-Fi already, you're all set. If not, get one before you start the setup or purchase the model that includes those features.

    Color me impressed, I'll be dropping their gateway off at my local Xfinity store and saving a few bucks.

    5.0 out of 5 stars The best of the best Docsis 3.1
    Reviewed in the United States on November 10, 2024
    OK, with everything being working from home these days, online shopping and bill paying, researching, news, TV, and so on, I had a real need for speed and although my ARRIS Docsis did the job at almost 100 Mbps, it was not cutting it with seven high speed computers on routers and switches and one coaxial cable at high speed from COX. I signed up for high speed at COX but was not getting it. The issue was Docsis 3.0, cannot handle the new standards.

    So I did all my research from high prices to renewed, and found that the new guy on the block that seems to make only a few products, mainly the Hitron CODA56 Multi-Gigabit DOCSIS 3.1 Modem | 2.5 Gbps Max modem, seemed worth looking into. It wasn't the highest price, so I was suspect a little, but do not go by price alone. So I do reviews. The reviews were outstanding. A few reviews were a little down but I now know why.

    This is why I think some are having problems, not with this one, but all others as well:

    When you are upgrading speed, the latest standards are just not important, it is vital. If you keep the older Linksys SE1500 switches and router that runs at the 10/100 speeds, which were wicked fast for the times, you will stay at that speed. So, here's my biggest tip. Make sure all your older switches connect your scanners, printers, and peripherals that do not need that much, no need to discard the switches and buy all new GB switches and routers, just use it for peripherals.

    Also, with APC power containers in event of power failures, any switch lines going into it need to be taken out unless you have the newest models because, as I found out the hard way, it will limit you to the older standard. You can still use the APC without the lines or buy a new APC.

    Now, if I haven't scared you, it is really dead simple. Take the time to get the information, most of it is given to you along with the MAC address on the label on the box itself and call your ISP, and as long as you have done all the connections to your modem, just needs to be switched on and a competent ISP person will walk you through. Ours is COX. I know this model favors Xfinity of Comcast fame, but this model works with the most major carriers I have ever seen.

    That being said, most all the reviews were for Xfinity. I found you also need to use a tool and make sure the cable from the ISP is securely screwed on.

    Well, mine is a COX ISP, so all those that would like to know, COX is the catch up company still growing like lightning all over the country and for good reasons. They do mostly direct connects. Not all this wireless 5G do anything is all that reliable I believe. Anyway, I like direct hookup to cables for reliability.

    You hear all about wi-fi drilling a hole in your head. I believe it. So, I use routers and connect a TP-Link with an on/off switch, not expensive, and can connect a wireless for when I need it, even a travel wireless by ethernet or USB, but I can put it off to give my home a peaceful feel without wireless running except for when needed for laptops and kids. Shut the wireless off, shut the kids off, lol.

    When the router is GB and switches are GB and modem is GB, you have it made. It is as simple as that. Now it would have taken me about 30 minutes with COX to upgrade but I made all these mistakes I just mentioned here. I mentioned it in the hopes you will not make the same mistakes I made. Even with my mistakes you can learn from, it took me about 3 hours to get seven computers running.

    As a side note, don't fret your printers, drivers, windows, or setup. It is just upgrading your speed. You can always put your old modem back if you have to but I see it as the worse thing that can happen, or most likely, is your speed doesn't change. In that case, you will have your new modem running but using the older speed. Don't panic. There is some switches or routers that are older causing the speed not to increase. For all the new first timer setups, no problem, you will have all the newest stuff. This is just tips for us older timers, lol.

    Also, check your plan with your ISP. It may not be the higher plan. This is the best router I have ever seen that in this online world and it should not mean a technician will have to come to your home and pay $75 an hour or more. Buy this modem. It will pay for itself in less than a year without having to rent it from your ISP monthly charge. It works, it is brand new, and not refurbished with some renewed ones from Amazon even cost more on some of the more famous models.

    Always look at the number sold in a month, how RECENT the reviews are, and the product itself how many ISP's they support. I am sometimes in CT and live in RI and if I move, this modem handles so many different ISP's, that it can go with me and even for remote, I will never need 2.5 GB speed when I was getting along with just 100 Mbps. Now 1 GB modem speed is all I will ever need but nice to know if I need to download or upload a huge amount of data that I can up my speed with COX to 2.5 GB.

    Just like the old axiom, you are as strong as the weakest link, so remember with online website and cloud stuff, you are only as fast as the server you are on when in the cloud and, of course, assuming you have a decent speed computer. I highly recommend the Hitron CODA56 Multi-Gigabit DOCSIS 3.1 Modem | 2.5 Gbps Max modem.

    I took the time to write this because this Hitron company is running a huge discount right now, I think 43% at this time I bought it, cheaper than most. So, for cheap, I wasn't sure I should buy it, the you get what you pay for. In this case, this is a quality item and better than the pricier ones I believe, else I would not right this review. Mostly, it is so a few of you reading this not to make my mistakes. Upgrade your routers and switches, all should run at GB speeds first. Then call your ISP and connect your MAC address.

    In fact, they give you the number to call and it is the only one for any price I could see that claims it can handle 2.5 GB speed for the price.

    Hey, it's Amazon, don't work, can send it back. I ordered this modem last night, got it today around noon time and on a Saturday! Can't beat Amazon! Hope this helps anyone thinking of buying this model, 5 stars in my book.

    5.0 out of 5 stars Works well for Xfinity

    It was an easy setup, clear instructions and a recommended router per xfinity. Speeds are definitely noticeably faster.

    5.0 out of 5 stars Excellent Value and Performance
    Reviewed in the United States on January 26, 2025
    I used this on Xfinity and was pleased with how easy the setup was. While I still needed to call Xfinity to complete the process, it wasn't too much of a hassle. The performance is excellent, and it offers great value for the price. The only downside is the lack of web management or a user interface, but given the overall quality and affordability, it's a minor issue. Highly recommended for anyone looking for a reliable and cost-effective option.

    5.0 out of 5 stars Faster upload w/ Comcast/Xfinity
    Reviewed in the United States on December 1, 2024
    Delivers slightly better than the plan's sticker (800/110). Can install the modem without a technician, their fee, or half day window.

    - Connect the modem and turn it on. Wait for the online light (@) to become solid. If the upstream light keeps blinking check your connections. The upstream/downstream lights might be solid green or solid blue at this point. Coax can get permanently damaged with tight bends, and the center conductor can get corroded requiring cable or connector replacement.
    - Use xfinity app to activate the modem. You need the MAC address off the modem. Your phone will need data to do this either from carrier or "xfinitywifi" hotspot. It will take a few minutes then the modem will reboot, and you should get upstream/downstream solid blue and a solid green connection light. Internet should work.
    - Run speedtest. If you continue to get 18-20mbps but your plan has a higher upstream limit, reboot the modem. After several reboots over an hour or two it should finally get provisioned for higher upspeed. If you don't get faster upload the next day after a reboot (or are limited at about 60mpbs but your plan is faster), you'll unfortunately have to deal with the technician dance. There are analog filters upstream in the cable that they'll have to remove to enable faster speeds. They should be able to demonstrate a speed faster than your plan on their cable tester device at the point where the cable enters the house.

    Pros:
    - Gets advertised faster upload speeds

    Cons:
    - One of very few higher speed modems you can buy (vs rent).
    - Modem is extremely large even though it doesn't conceal a wifi antenna.
    - Unlike Arris modems, modem status page is not accessible through most routers (unless you can configure your router to have a 192.168.100.x address on its WAN port, in addition to the DHCP address from comcast. For most people this means it only has a status page when you directly connect a PC to the modem, reboot the modem, and set your PC to 192.168.100.x. The only time a status page is useful is when you have poor performance due to bad SNR, you know what that means, and need to argue with a technician who doesn't want to fix the problem (and won't show you the test results on their portable line tester). This is tiny fraction of users.

    Increasing the upload speed will improve your VPN experience if you work from home. It will also reduce latency when upstream of 18mbps is the bottleneck (which can force latency up to several hundred ms, making gaming experience very poor).
