Hitron CODA56 experiences?

yes definitely interested as i'm looking at this as well for cyber monday deals. 

yes, does it work up to 200 Mbps up?

@petersk - The CODA56 device is listed on our compatible devices list for our next-generation market, and will work up to 455 Mbps wired upload speed

Hi there! Thanks for your detailed message, sorry to learn of your experience since buying your new modem. Based on what you mentioned I would suggest reviewing the service plan in detail. Gigabit equivalent speed tiers have been available before the next-gen rollout, and having an older or "legacy" plan would also cause a hiccup in acquiring the higher speeds. How long has it been since you had that same service plan? 

Customers will not receive faster upload speeds if they:

- Do not reside in an Enhanced Speed market
- Have Internet Essentials/Internet Essentials Plus or Prepaid Internet
- Customer-owned and managed (COAM) modems that are not the approved list at this time
- Have an XB2 or XB3 Xfinity Gateway
- Are on a Legacy speed tier (examples include Blast! Pro+, Performance Select, etc…)

I purchased this modem and went I went to install Xfinty said it was not approved. I don't understand. I bought it because it was supposed to be compatible.

Hey there, @user_52mnn0! I am sorry to hear about the experience. What modem did you buy? 

I too just got the Coda56, I've been using an MB8600 for a couple years and it seemed to be working pretty well, I pay for 1200/200 and was seeing 600/40 on a daily basis. The "40" was driving me nuts and I got an email from Comcast suggesting I upgrade the hardware to improve the upload speed, something on a short list that included the Coda56, so I decided to give it a go. Immediate speedtest results were 900/240, fantastic! But then, a day later, it's 950/80, and a very consistent 80 that looks like something is capping it. 

At the same time I noticed the 80, I got an email that a tech needed to come look at my line - they came out today, detached and reconnected the cables, rebooted things, declared that the "ingress issue" was solved and left... they were very nice, but I'm still getting 950/80. :-) It's 2x the upload speed I had before, but where'd the 240 go?

@markdeloura  are you hardwired ethernet straight to the modem? i was originally and i was getting very fast speed. santa didn't bring me a new router with a 2.5gb port so i'll have to keep an eye on sales so i can get > 1tgb. you might be capped by your router with 1gb ports only.

only 1 machine of ours - my personal desktop - can take advantage of > 1tb since my motherboard has a 2.5gb port too. . i can't remember what wifi level i need to be to get higher than 1gb on wireless (have to look at all the 802.xx stuff). but probably mine and the soon kid's gaming pc will be the only ones capable of getting that speed though kid's will be wifi connection w/o ethernet ports in his room. 

Try to disconnect the cable from the modem and reboot it. Reboot your router at the same time. I don't have a CODA, but with modem that are working as a bridge like here, this was the only way to access its admin page. Not sure if this will help you. Some provided the info about the IP and how you need to setup your adapter. A few things to try.

The Coda56 actively blocks any connection requests that don’t come from an ip address in the 192.168.100.x address space. There are ways to trick it by adding a second virtual interface to your router (Asus works), but it’s beyond the scope of posting here.

See https://www.dslreports.com/forum/r33757940-Hitron-CODA56-status-page-access

The diagnostic page of the modem is garbage though.  It has logs, but they aren’t visible on the UI page. The signals it reports make little sense either. 

@user_kcu8gv​  will setting the router starting IP to be 192.168.100.1 allow me to see it? i have mine at default 192.168.1.1 though i have the static dhcp to be in the x.x.x.100 range. 

@user_kcu8gv​ Thanks, I was hoping to avoid that since I'm lazy but I'll give it a try hardcoding an IP on my laptop.  I hate doing that because in the past, I have had problems with reacquiring an address from the comcast servers when I switch back & forth between my laptop and router being connected to the cable modem.  But I'm sure it will be fine...

@user_dtuno3​ i just checked amazon as a starting point. then go to ebay, best buy, wherever reputable to see how things compare since being in amazon doesn't always mean it's the cheapest price. Far from it at times. 

hope you're sitting down when you see the price for the ARRIS SURFboard G54

i kept my old arris 6183 which works perfectly fine except that comcast caps it at 25Mbps upload for no good reason.  That's still 5x faster than with my old plan so uploading backups to cloud storage still works a lot better.  I'm not going to pay $500 plus for a new cable modem without a better reason.  The Coda (not 56) was $80 on sale, that I was willing to pay.

It works initially and then weeks or months later, the modem will start dropping connection to your LAN.  Give it time...has happened on two of these CODA56 modems.  Went back to the Arris S33.

@user_7f78ff​ Have you researched / found anything as well performing as the CODA56 but more reliable? They originally saddled me with this frickn' xb7 modem/router but I'm ditching this thing since I already have a phenomenal router and want to invest in a solid modem. I don't feel like paying $140+ for something that is going to have performance issues after a few months.

@user_kcu8gv​ Hi, how did you get the new boot/bin file sent to the modem? Just set mine up and getting great download but upload is capped at 5mbps (should be 100 or close to it on my plan). Xfinity support said i need to contact the manufacturer, but wondering if there was another way?

Thanks in advance

@user_7f78ff​ 

Mine started dropping WAN connections, not the LAN.  Xfintiy would say the modem was offline, but all lights were still solid and I could ping the modem from the LAN.

@Morac2 Hello, I am happy to be of assistance. Can you please send us a DM. You can start by clicking the chat icon located in the top right corner of your forums' page when signed in. Once there, you can direct your messages to "Xfinity Support." Please add your full name and service address to help us locate your account. Let me know if you have any questions. 

@user_zqz452​ Faster upload speeds are only for Gigabit Extra and Gigabit X2 plans. Do you have one of these plans?

@user_7f78ff​ Thank you so much for sharing those details regarding the faster Uploads, and sharing the link for us! Have a wonderful rest of your day! 

@user_7f78ff​ Sadly it all depends not on your plan but on whether or not you are in the upgraded "10G" zone.    I found out after several hours of chat and direct messages, that I am not.   How one finds this out?   You have to direct message someone at Xfinity on this forum.  No one else seems capable.  Nor can they tell you when or if this will occur.

Sorry hear about the issues. I'm using the CODA56 and was curious about how you viewed the logs. I did it by directly connecting to my computer when I need to, but then I lose internet through the router. Did you get it to work while connected to your wifi router?

Hello tuckerskahuna, we're limited in the troubleshooting support we can provide for 3rd party equipment, but we'll do all we can. Were you able to activate your new modem or connect to your network name? 

@tuckerskahuna​ No need to change your router IP range. The modem just passes the signal to the router and the router does all the heavy lifting. The modem IP is just there for you to address the Modem directly to get some modem information (limited). 

@XfinityMarcos​ 

I did get the modem working tonight, and got my router connected with my regular IP DHCP so everything came up.  It took a few tries and reboots for the modem to be happy with the router but it took.  

Is there a way to connect to the modem's administration page?

I got this new modem to replace my very good Netgear C7800 modem/router. But the Netgear is not approved for the new upload speeds.  This Coda56 is!  But I am getting the same download and upload speeds as before.   I received an email this week about the new speeds.  I need more upload speed as we have two remote workers in our home who use video a lot.

What can I do to get the best upload speed?

I have the Extreme Pro+ Plan  1Gig down and 20mb up with the unlimited on top.  I get 900 down and 22mb up with both the old and new modem. 

I ran the troubleshooter again tonight with the new modem and it says everything is fine.

Greetings again, @tuckerskahuna! Thank you for following up about this. If your neighborhood just received the mid-split upgrade, there will be a specific series of communication events and requirements that need to take place before the next gen upload speeds become available.

The first and most important event is the mid-split upgrade itself. You will usually receive advance notification this is happening about two weeks prior to the upgrade. That initial email will mention the "mid-split upgrade" by name, and will usually cover all the necessary details and requirements for the increased upload speeds. It should also provide an estimated timeline for the upgrade process.

On order for you to receive the increased upload speeds after the mid-split upgrade, you will need to have an Advanced xFi Gateway (XB6, XB7, or XB8) or compatible third-party modem like the Coda56. You should be fine there. In addition to having a compatible modem, you will also need to have a current internet speed tier, like Connect, Connect More, Fast, Superfast, Gigabit, or Gigabit Extra. If you are still subscribed to Extreme Pro, which is a legacy speed tier, you may need to upgrade that before you can receive the increased upload speeds.

Once the mid-split upgrade has been implemented, everyone in your neighborhood will receive an in-home assessment test (iHAT) to validate the new upstream bandwidth to your home. These usually take about a week to complete. Once your home has received the iHAT, you will either receive an email saying the assessment passed, and the increased upload speeds are now available, or you will receive an email saying the assessment did not pass, and you will be able to schedule a free technician visit to address any issues.

The email you listed in your post was a little different from the mid-split notifications or iHAT results emails I've seen. That one may have been referencing a different speed increase that was recently announced on our website here: https://corporate.comcast.com/press/releases/comcast-boosts-speeds-xfinity-internet-customers
