Color: White DOCSIS 3.1 Modem 2.5Gbps
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.

Color: White DOCSIS 3.1 Modem 2.5Gbps
TL;DR: 1) The CODA and CODA56 seem to be the best price/value buy for Comcast/Xfinity in 2024 2) Comcast/Xfinity certified for their new improved upload speeds (100 and 200 Mbps, up to ~455Mbps) 3) Easy install via new Xfinity app (no interaction w/ CS needed (yeah!!!) 4) Shaved off 5-6 ms in ping times on my end for both wired and wireless connections with only the cable modem swapped 5) Stable! Long version: So far so good, it's been running 72h so far. I had a very stable setup with the Netgear CM1100 cable modem (excellent as well) and did not really need a new modem, but read somewhere that Comcast offers new uploads of 100 and 200 Mbps in the Bay Area if you have the Gigabit or Gigabit plus speed tier. The CM1100 does not support that. But it also depends on your exact address and if available already at your place (apparently not for us). In any case, I kept reading and figured I get us ready and get a new modem. Never heard of Hitron (Taiwan), but reviews were OK, so I gave it a shot. It works. Best ever modem install. Downloaded the new (purple) Xfinity app and deleted all the old Xfinity Connect and Account apps (discontinued). Launched the new purple app and said new equipment, entered the MAC address (via cellular Internet), connected and plugged in the new cable modem and voila. App was searching a few minutes, then downloading new firmware to cable modem, restarting, and we were live. No wasted 45min chatting with CSR as many times in the past. I have the 2x ASUS RT-86S routers running Merlin in mesh behind the modem and a set MAC for WAN there, so nothing else needed to be changed. Rebooted the AI-Mesh and the modem one more time and everything has been running fine the last 72. I have "SuperFast" speed or whatever they call it listed at 800/20, and I usually get about ~940/24 wired and wireless download depends on the device. We have mostly Apple and only the new 15pro supports 160 MHz WiFi, so I have 160 MHz actually still turned off so far. The 15pro is by far the fastest WiFi device in the house, I have seen ~940 download on WiFi now for the first time when I tested the 160 MHz shortly. I checked with Comcast, and I cannot get the 100 upload yet, but it's supposedly coming... The one thing I saw that the modem change reduced the ping times. From a regular ~15ms on wired it went to ~9ms, I even saw 8 once. And on wireless I see 12-15ms now instead of 17-20ms. I am not an online gamer and don't really care, but that is good reduction and consistent. Of note: This modem has one 2.5 Gbps Ethernet port only (downward compatible, of course), but you cannot do WAN aggregation. So, if you have the RT-AX86U/Pro with the 2.5 port and want to use that for the LAN, you cannot leverage higher WAN speeds. The CM1100 allows to combine two 1Gbps ports and the AX-86S/U allow to use 2x 1Gbps for WAN as well, and then you could use a 2.5 Gbps for LAN. If any of this concerns you, then the Netgear CM3000 modem may be your friend, albeit at a much higher price. It's also on the recommended Comcast list supporting the latest speed tiers. It has 3 ports, 1x 2.5 Gpbs, and 2x 1Gbps for link aggregation. For regular use though, from a price value perspective, the CODA or this CODA56 seems to be the way to go. The regular CODA is the cheapest of the bunch and the only difference is the 1Gbps port vs 2.5 Gbps port. Both support up to ~455 Mbps upload speed on Comcast/Xfinity as stated by Comcast.

Easy installation. Comes with a quick start guide. There is a downloadable manual at the Hitron site. Also comes with high speed coax cable, and ethernet cable. Activated with Xfinity. Internet up and running with a separate owned router attached. Everything working perfectly together. No hiccups or workarounds needed. Only configuration change was a new ip address. Ran a speedtest and delivering reliably fast internet. Also, want to mention I had never heard of Hitron brand and was reluctant until I did my research. Very happy with the quality of the modem and the price.

Update 5/1/2025 I have been using the Hitron for over a year. After a refresh from Comcast, the booting and looping bug are gone. I go months now without reboot, it is rock solid and even with the price increase, it delivers the speeds as advertised at a third of the cost. Still not the best looking piece of hardware but for the price and performance, you can't beat it. I'm very please and happy with the hardware. Update 10/22: After losing power in my office and the UPS going out while I was gone my first Hitron went into some strange loop. I left it on for 2 days but after pulling the power and leaving it on I had to purchase a new one. The new one has been on without problems for almost a month. Bottom line, this unit is a third of the price of a Netgear or ARRIS, the only other approved modems for Comcast's top speed offering. Don't get me wrong, the Netgear and Arris are very good modems but even after replacing my first Hitron modem, I'm still ahead on coast and it works as advertised. Updated 5/19. Pros: When up and running no issues, pretty solid. Cons: Not very good looking. Boots extremely slow There is a reoccurring bug, repeatable. A sync problem between the modem and my Wifi 7 router observed by a Comcast service guy. Had a tree fall on the street taking out power, telephone and I thought (and was told, cable from the power people). Tech from Comcast came out and to check everything at the house and noticed the issue and recorded the problem but still no fix. Initial install in December: No QR code (as shown in the documentation that came with it), I had to call support with the MAC address to get it provisioned (always fraught with peril when contacting Comcast). Not the sexiest looking piece of hardware. I was hoping it came in black so minus 1 star. Hit a strange bug this morning. Unit was up but no connection to Comcast. I rebooted both units and nothing, then rebooted the modem again and it started working.

I bought this model a recommendation from one of my techy sons - and I couldn’t be happier with it. Set up and activation (dreaded) was an absolute breeze! It’s compact size is ideal for the space I had and all I had to do was plug it in, wait for all the lights to light up, and since my internet provider is Xfinity, the rest of the activation was in that app and it was as simple as watching it do its thing and it told me when I was done! Seriously, I had no idea it could be that simple. The streaming performance has been flawless (it’s been a week), it makes no noise and the brightness is visible but not distracting. This fits my needs perfectly and I’m pleased - highly recommended.

So I decided to give the CODA56 another shot. I "upgraded" from the Netgear CAX80. Comcast app makes it easy to change the modem over to the new one. So that was painless. The modem lacks a UI unless you have a very particular setup and you know what you are doing. Otherwise you have to directly connect the modem to your computer and do some fine tweaking with it to bring up the UI. Not ideal. But thats for us nerds. Everyday user it should be A OK to use and connect to a router. It works flawlessly thus far. Now Comcast says the CODA56 is "mid-split" ready as well as my CAX80. Im very doubtful that my $450 CAX80 can work on mid-split. Why? Well the CAX80 seems to be capable of doing uploads at least to 40MBPS, I can confirm this when I was on Comcast's Gigabit Plus plan. On Comcast's 300 MBPS plan (it really is crazy that you really dont need a gigabit down unless you have literally 50 + devices online at the same time watching a 4k movie, 300 will literally work for pretty much anyone) my CAX80 caped about 22 MBPS. Now this is where the CODA56 shines. As you can see on the screenshot, I'm on the 300 MBPS Comcast plan, but I am no where near 20MBPS upload I'm in the 110's! Having a ample upload can actually impact your internet for a "faster" experience, because as much as the download is important, upload and also important because even though most of the work is being done on the download end, your devices still need to communicate out to let the server know where you are in the process. I have noticed a slight increase in webpage loading. It was almost instant before, but now its less then that. And if you do have multiple devices on at the same time this will help compensate and make your experience faster. I wonder what the upload is on the Gigabit plus plan, ill be honest, I'm happy with the 115 up. Remember this modem is only a modem and NOT a router, you will need that separately. My CAX80 was a combo Modem/Router. But my wireless interference in my area is terrible and there's no room on the 2.4 Ghz and the 5GHz to operate even close to these speeds. So I have this modem with a ZenWifi ET8 mesh. Both units are wired and all my wireless devices are 6E (except my smart thermostat, it can only 5Ghz, but its not far from the unit and it doesn't need speed to work), man I get the FULL speed of my internet on these devices. Its AWESOME! Not sure if you have "mid-split?" Just goto Comcast online and see if you can get the 2000 Mbps plan. If so you got mid-split. Heck I would even recommend just buying the modem to get the faster upload then what you are probably getting now.

This thing is definitely way faster than my previous cable modem router with built in WiFi. I am really surprised how much snappier and quicker it feels because the one I had was higher end, it was just getting older. Now that I have separate access point and switch I just need a cable modem that just does the cable modem thing, and this does that one job really well. I am really happy with it! One thing it doesn’t explicitly state is that it does support 1gb Ethernet just fine, truly multi gig no problem. Great!

I guess I really don't know how to review this model so picked middle of the road. But can share my failures and frustrations getting it activated with Comcast/Xfinity. The first CODA56 modem Amazon sent had a MAC ID that was already registered in Comcast's customer database and they couldn't reset it and assign to me -- nothing tech support could do for me. However, since the CODA56 appeared to work with Xfinity, I bought another with 1 hour delivery (very cool, although Amazon selling me a returned unit as new was very NOT-COOL). The second CODA56 was a bit newer than the first, the last few digits of the part number were a few digits higher and the serial number was about 200,000 units later (assuming Hitron uses sequential S/Ns like everyone else). After hours on live chat with Xfinity this cable modem failed to activate as well. It seems Xfinity needs to be able to somehow correlate the MAC ID with the manufacturer and they could not. So, this modem maybe great and perfectly good device, but not with Comcrap Xfinity. I also picked up a "cable modem only" device from my local Xfinity store which the first live chat agent told me the stores had -- but it turned out to be one of their all-in-one cable modem-router-WAP-VoIP boxes. That was all the store had. That worked as an all-in-one, but would not work with my router in "bridge mode." I could reach some IP's on the internet, but not others, and the DNS addresses assigned to the router were not reachable. Plus it was huge and pumped out a ton of heat, what a POS (model was CGM4981COM if anyone cares). It took another hour with live chat to get my original cable modem working again, which is insane. They also promised me they could ship me a "cable modem only" direct from Xfinity for $15. I was super frustrated and said "fine." It showed up the next day -- fast, nice, right? Only what they shipped me was another CGM4981COM POS. At least I can return both to my Xfinity store at the same time, and I better get my $15 back. I pissed-away 9 hours of my weekend on this, should have been 30 minutes or less task. I will say all the live chat agents I spoke with were very responsive and as helpful as they could be, but I think they are stuck working in a broken system. So now I've ordered the Netgear CM3000. Almost twice the price, but it is the top-rated cable modem and supposedly blazing-fast. I just want to be done. Fingers crossed.
