Download speed problem with 3rd party modem
History of my issue::
Worked perfectly for almost 4 years - consistent download 750–800 Mbps.
Around mid-August 2022 my download dropped by 300 Mbps. I watched it for several days and called Xfinity.
August 24, 2022 – tech came out to check all cabling outside and up to the modem. He then stated that it was the modem. The modem works fine, it just drops on speed and was not malfunctioning like on and off.
I went out bought a new Motorola MB8611 modem (sanctioned by Xfinity) and installed it. Download speed was the same. Called Xfinity and they said a tech needed to come out.
August 29, 2022 – tech came out to check all cabling outside and up to the modem. He then stated that it was the modem. Tech was baffled and said a Supervisor would call me.
No Supervisor called at all. I called back to Xfinity and was told that because the issue was not repaired it goes to a tier 3 so that when a tech come next time a Supervisor will be there as well.
September 5, 2022 – tech came out and before he started I asked if he was familiar with the past notes from the last 2 visits. He said NO. I told him that I was told that a Supervisor should be with him to tackle the trouble call. He said he would call his Supervisor for guidance. The tech said no Supervisor was coming because he was a 3rd party tech (with an Xfinity labeled truck). He was definitely confused. Finally, the contractor Supervisor got a hold of the Xfinity Supervisor. The Xfinity Supervisor said I will be calling the customer.
Again, No Supervisor called at all.
August 29, 2022 – tech came out. I asked him if he read the past notes. He said he did, but could not work on the ticket because my 3rd party modem did not have my Xfinity phone service-connected and it was a liability. I actually pleaded with him and then he checked the line inside the house only and said it looked fine. He stated that I should buy another brand of 3rd party modem. The download speed was still degraded. No fix by this tech.
I went out and bought 2 Arris SB8200 modems. I called Xfinity again and they said that another tech needed to come out. No other way.
September 12, 2022 – tech came out to check all cabling outside and up to the modem. He then stated that it was the modem. Tech could not fix the download problem.
I called Xfinity again. They said again that a tech had to come out for the repair.
September 16, 2022 – tech came out to check all cabling outside and up to the modem. He was baffled at the download speed. A supervisor did show. Why I have NO IDEA.
I called Xfinity again on September 19 trying to get an XFINITY modem provisioned (what a job over the phone). The reason I went to get the Xfinity modem is to prove that the speed is still the same as a third-party approved Xfinity modem. Can somebody in God's name tell me what this company is doing? They waste resources, but always want your money at the end of the month. I am now going on #7 for a tech visit on September 21, 2022.
What do think will happen this time? This is turning into a Circus for sure. I never had this issue before. I am pretty sure that a config change on their network/infrastructure side has caused my almost 4 week pain with these people. Xfinity said they saw a problem over the network on the downstream to my modem. I was told multiple times by the Xfinity tech person on the calls that they saw the errors. What the heck is going on HERE?
Does anybody think somebody at Xfinity will read this or maybe figure this issue out?
I asked one of the techs, which 3rd party modem does Xfinity recommend I purchase to remedy this problem. No answer – fell upon deaf ears.

Another visit by Xfinity
September 21, 2022 - tech came out to check all cabling outside and up to the modem. He was baffled at the download speed. Tech said he pushed it to the back-end for maintenance.
What do think is going on here? Does Xfinity know what the hell they are doing?!?

You are not alone my friend. In my case, it was even worse because there was no tech showed up on the scheduled date.

You should contact the headquarters at Comcast to file an Executive Complaint, which is a level higher than regular customer service. The phone number is [Edited: "Personal Information"].

All in All - the issue is the left hand does not know what the right hand is doing in a nutshell. The agent on the phone at Xfinity says one thing and the tech has a totally different approach. Are the top Leadership dogs at Xfinity pulling their weight? Probably NOT!

Remember, I was getting roughly 780 Mbps download, and then it drops to this. You are ripping customers off. It's a CRIME!!

That is incorrect. Again you are reading from a sheet. They do not use laptops. They should have laptops like customers do - they have a sophisticated meter for testing downloads.
You all need to get your wording together.

One tech brought in a laptop as a hunch and only got 200 Mbps for download. Then he figured out he didnt have a GIG network card in the laptop. Again, this is all a crime.

You know bought a new modem for the 1.2 down 200 up. Well the new modem got 700 down and 5 up. I thought the modem must be bad. Hook up the XB8 back up and I must have been right since 950-1.2 down 50 up which was better then 5 up. Get another new modem install it and 700 down 5 up. What are the odds two different modems (3.1) same exact speeds. Then when 192.168.100.1 into the modem the down Signal is some long HZ number staring with 711*********hz. I call and was told there must be some leak at my end since they show all working great. I read the same thing here on this forum people asking about this and they were told it all looks good so must be a leak at your end. And I know they are doing the best they can. So hmm what if I put the XB8 back in? I did and 950 down 230 up. WHAT?
Modems used this week. Motorola 8611 and Netgear nighthawk cm2000. Since I kinda know a few things when it comes to this.. and anyone can clearly see there is no problem at my end. It does make me wonder is there some fine print somewhere? Its their network they can do what ever they want. Money can be tight these days and wanted to save $25 a month :) I do love the XB8 and have no complaints with with Xfinity. I will say with the APP which at first is great easy to activate new modem...but every time I would activate the new modem 700d 5 up then back to XB8 with the app I got 930 down 40 up. So today trying to use the app.. said nope contact them chat? You hit yes and get a blank white page every time. So had to use the phone to use chat to have them call since that is SUPER FAST and she was awesome! This time she said she would do it manually and haha guess what the speeds are with the XB8 930 down 230 up.
hmm

Jim,
As far as the modem logs, I did point out that on the Arris SB8200 (newly purchased) I was not getting a blue light on the upstream. The light on the upstream was white in color. I called Arris and they said that the white means “Incorrect signal coming into the modem”.
On the Motorola, MB8611I had some errors in the event log. I did not call Motorola tech support because they was nobody available. But I do have the event log though.
I thought the tech ops team was monitoring this problem. I was told yesterday that as of August 20 they were monitoring. I was also told that they saw some errors and a bad speed test.
Again, there are multiple people and teams on different sheets of music. It is mind-boggling how Xfinity can function.
Inserted are 2 different event logs. One from the Arris and the other from the Motorola.
Arris
Motorola

One last item I want to stress here folks. When this all started in August 2022. The UPLOAD numbers have never changed. The DOWNLOAD numbers have changed. To me, that is key here in the resolution or at least should shed some light for the folks at Xfinity.
As of this morning August 24, 2022

Here is the latest from direct messaging for all post readers. “XfinityJim” suggested on September 24 and I quote “I will be more than happy to get your case over to our Executive Relations Professionals. They work with Corporate, I am sure they will be able to address your concerns”.
Let us see how long this process takes.
