Hitron CODA56 Activation issues and slow speed

I purchased a new CODA56 to replace my Xfinity modem. I first called Xfinity at 8 a.m. today. After 6+ hours on the phone with different reps, there is still no resolution. One rep added the wrong mac id, and the next rep added a different modem. Then, once the modem was added, they removed my internet plan entirely from my account. I had to Google the modem issue to walk a rep through getting myself a solution. One of the reps told me I needed to change the password to my Xfinity account (not my Wi-Fi) and that would fix my Wi-Fi issues... I'm at a loss for words with the experience I’ve had today dealing with Xfinity.  Currently, as of now, my modem has internet, but my speeds are still capped at 150mbs yet my plan allows for 2 gigabytes. The last rep said they were going to send "super strong signals" over the next 1-2 hours to my modem, and he was supposed to call me back 2 hours ago.... I'm not even sure what to do at this point.

Update: A technician came out, 2 hours later confirmed the hardware is perfectly fine, and it's a software issue. I bought another NEW Hitron CODA56 modem (expecting Xfinity to say it was defective) and had them install it, and again, the same problem. The tech confirmed that it's a software issue coming from Xfinity customer service, and there's nothing he can do physically. Essentially, 2 hours wasted. I'm supposed to wait for a callback from another tech tomorrow. At this point, I'm contemplating splurging on the Netgear CM3000 Modem and hope I don't run into the same issue. This is going on 36+ hours with no resolution in sight, just to add an Xfinity-recommended modem to an account... extremely ridiculous.

Purchased the Nether CM3000 modem. Getting the same speed issues after activation. Another rep said they have to send another tech out. 3rd tech in 2 days. It really makes it seem like Xfinity is forcing consumers to use their modems by making this process so difficult you want to give up trying

Thanks for reaching out to us we do apologize with any inconvenience you're having with your services using your own customer modem. If you actually have another tech coming out in the next couple of days, the hands on tech will be able to get your modem activated and check the speeds and check everything inside and outside the home.  

 

Since this is a repeat issue the technician will most likely have Xfinity equipment with them so they can test everything inside and out and roll out any possibilities and go to the next steps.

 

What I would like to do is follow up with you in a couple of days to see if the techs  got everything updated and working as it should be

@XfinityOrlandoM​ Both technicians who came out confirmed the cables and hardware are fine, and the issue is with the provisioning. They say there's nothing they can do, and I need to call customer care. Customer care runs a diagnostic, and says everything looks fine on their end, so they need to send a technician out. I'm in an endless loop. This is day 3, I've had 3 technicians at my house over 3 days, spoke with 12+ different reps over the phone and chat. I've bought 3 different modems, and it's always the same issue after activation and provisioning from Xfinity. My speeds get throttled down to 100 Mbps, I'm on a 2gig plan. I actually get better speeds (300mbps) with the new modems before I reach out to Xfinity to provision the modem.

@user_yoi1xy​ I had a problem like this a few years ago when I upgraded my modem.  At the time I had 600Mbps down (~720 actual), which had been bumped up over the years from the 150 I had when I first got Comcast service.  Fire up the new modem and all of a sudden I was getting a rock solid 180.  Apparently, the system provisioned it for the 150 I originally had, which wasn't even an available speed at the time.  I just went ahead and upgraded to the faster 1200/40 plan I wanted, and as soon as that went through I was getting ~1400 down.

I'd try downgrading one speed tier, then upgrade back to 2Gbps later if you want.
