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.

Swapped out my older modem for this Hitron CODA56 and the difference was immediate. Setup took just a few minutes and it synced right up with my provider. Speeds are consistent, latency is low, and the 2.5 Gb port works perfectly with my multi-gig router. No random disconnects or overheating after several weeks of use.

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.
