My buddy got his new XB7 with much trouble from Xfinity trying to get it. Lot's of okay we'll ship it and they never did. After several days and several phone calls he finally got it hand delivered from a tech already provisioned. It's working for him in router and bridge mode full speed. He's had it for a few days now and he's had no issues.
Mine is also working well still. Got my new equipment and have moved onto a new issue with chromecast not working even with MDNS on the new UDM Pro. AirPlay is working, but not Chromecast. Oh well... always something.

Yes to the above. IPV6 on or off didn’t seem to make a difference for me. Hardware Nat “on” did. 2.5 connections are not very common yet, but it is growing. My Synology NAS offers it. Looking at the UDM Pro so I can start doing VLAN’s. And also because the regular UDM isn’t WiFi 6 and it would be easier to replace AP’s later than the UDM.

Still on the XB7 in bridge mode. I had IPV6 turned and Hardware NAT turned off on my Amplifi HD. The fastest I can get is about 917/42 late at night very early in the morning. It's close to 6PM where I'm at. Since my wife isn't working from home and no one in the house is on the internet besides me I thought I would experiment a little.
I ran some speed tests. I got 879/24 and 893/28. Figured it's prime tv streaming time. I turned on IPV6. The router did indeed grab an IPV6 address. I got 800/36 and 799/34.
I turned on Hardware NAT. I got 945/36 and 945/37.
I turned off IPV6. I got 949/31 and 949/36.
I turned off Hardware NAT. I got 844/42.
I turned Hardware NAT back on. I got 948/38, 948/41, 953/38, 949/38, 947/31. Looks like I need Hardware NAT on. These are the fastest downloads I've ever got.
Sorry this didn't help with the IPV6 scenario, at least not for me. I did tell my buddy about IPV6 and I'm still waiting for him to tell me his results or maybe he'll share them here. I'm looking at replacing my Amplifi HD with a Unifi Dream Machine Pro and FlexHD AP's.

I had a similar issue with ATT U-Verse. I had issues with them for months. Had several techs out messing with my lines connections each blaming the last guy. I finally had a supervisor come out and I showed him a sprectum analysis of the signal coming to the house. He than discovered I'm a electronics engineer. I switched to Comcast, now Xfinity, after that. This was about 8 years ago. We have 2 local AM radio stations that was interfering with the U-Verse signal. The neighborhood is still twisted pair phone-line which acts like a big receiving antenna. The U-Verse signal was operating in a bandwith that both radio stations were also in. Albeit the U-Verse signal being much wider, but the AM radio stations stronger causing a complete drop in signal in two spots making the U-Verse signal all but unusable. So I can totally appreciate your story. I run into this more often than I should They do try to take advantage of you if they can. I don't understand why people are so lazy anymore. Than you find a few that are willing to go the extra mile. I had an issue just a few months ago. Best Buy didn't want to install the dishwaher we had ordered. The guy came in the house and said it wouldn't fit after measuring it. I told him you're not measuring behind the tile because the dishwasher doesn't sit on the tiles. I get this song and dance about he's been doing this for years and he's a 100% positive it won't fit. Than I ask to measure the new dishwaser and thusly proving it will fit. He still refused to install it. There's a lot more to the story than that, but let's just say Best Buy hired a sub-contractor to isntall it and it only took 2 minutes to put it in and another 10 or so minutes to hook up the water line. Best part was the refunded the install fee for all the trouble. I could have installed it myself, but that's not what we paid for and end the end didn't have to pay for it at all. I don't understand techs these days. And the amount of flat out lying that is taking place. Anyways, I hope you all get the problems fixed soon. I hope mine stays fixed minus the node. It's defintely an Xfinity issue. I did share the IPv6 theory with a friend of mine as it's not the first time I read about it. He will try to that as a fix, if it is indeed turned off on his router, this weekend. His wife is working from home and cannot have service interupted. My wife is in the same position.

I get what you're saying about provisioning. And when my replacement XB6 much earlier this month worked great for a couple of weeks than all of a sudden did not. I truly believe that is a firmware or provisioning problem they're pushing on it. I've only had my XB7 for less than a week and so far so good, but they may push something bad on it. As far as the node.... the tech did show me that the upload on the node was overloaded which would negatively effect the download speed. During the day when there is a lot of traffic in my neighborhood and in the eveninings I can see my download speeds go down and the upload is also impacted. Late at night or early morning I'm getting full speed, at least full speed for me. When I was on the XB6 both times I had similar high speeds than all of a sudden I cannot get past 650Mbps and even the tech thought they had me on the wrong speed plan. He was confused. When he was troubleshooting he checked the node. So he knew that was an issue. Not the main issue we've all been facing, but a separate issue for my neighborhood. I'll continue doing speed tests to check to make sure my new XB7 doesn't get provisioned to a slower speed.

I got 839.44/13.61 almost 3 hours ago, 1:14PM my time. Quite obvious the node is being hit hard.
Way later at night when most people are in bed a little after 2AM I got 917.60/41.27 as my best. Which is what I was getting before I starting having problems.
When the upload on the node starts getting even more over loaded I get timeouts and major lag on websites and programs connected to the internet.
So far the XB7 is still working well for me, but will it last?
... View more
You are correct. The United States pays more than anybody I believe and we have the slowest plans.
Kind of like California and it's gas prices. We have some of the worst roads and the highest gas prices. Anyways. Node is still not fixed, but my speeds are still doing pretty good with the new modem.
... View more
Aside from the Node being overloaded during the day and till much later at night the new modem has been working out pretty well the last couple days. It's the new XB7 ( CGM4331COM) and I am using it in bridge mode. Around 2:30AM I'm hitting over a little over 900 down and 40-42 up which is where it was when I first got the service back in January. During the day the I'm getting anywhere from 10-20 upload which in turn slows my download by 50-150 roughly.
... View more
@Here4Help Considering it worked fine when I first got the 1GB service is January and the fact that I can hit 985Mbps transferring files back and forth on my NAS........I'd say yes my equipment is up to task. I know what the issue is. It's the Node across the street. It's at 90% capacity for upload. The line tech told me as much and said this is what is causing the slow downs and disconnects. They need to add another Node to split the traffic, but in a meeting the xfinity tech went to he said they won't do it. So I'm paying for a service I'm not getting. Furthermore, the problem has been identified and they refuse to fix it because of quaratine. The Node is outside! The quarantine is a poor excuse. Look at down detector. Xfinity nor ATT can handle all the data under quarantine, heck they have slow downs before quarantine. They're selling speeds that the infrastructure cannot handle.

Connecting from Xfinity Assistant. I have a question about internet.
A.K. 9:26:01 AM
You are now chatting with Sunidhi
Hello, thank you for contacting Xfinity Support. My name is Sunidhi .Who do I have the pleasure of assisting today?
Sunidhi 9:26:56 AM
Hello, this is A.K..
A.K. 9:27:12 AM
Could you please elaborate your concern so that I can assist you better?
Sunidhi 9:28:22 AM
I'm still having issues with my internet speed and it's been happening for the last 3 months. They troubleshooting system already did a reboot a few minutes ago and my speed actually went down even further. I am directly connected to the gateway, i do not use wifi.
A.K. 9:28:54 AM
I've been paying for the 1gb service starting back in January and I have not been getting that speed but a few weeks out of the last 4 months.
A.K. 9:31:34 AM
I apologize for the inconvenience faced by you and I will do my best to help you on this.
Sunidhi 9:31:53 AM
Please help me authenticate your account by providing your complete name and complete service address with zip code.
Sunidhi 9:33:33 AM
A.K. 9:33:57 AM
Don't worry. Your sensitive data has been masked.
Great, thank you for sharing the information, please give me a moment to review the account details
Sunidhi 9:35:25 AM
Thank you for waiting.
Sunidhi 9:38:27 AM
Just to confirm, may I know how much speed you are getting now?
Sunidhi 9:38:47 AM
A.K. 9:38:59 AM
It was just over 600Mb before the modem rebooted.
A.K. 9:39:32 AM
When it works I get over 850MB to just over 900Mb.
A.K. 9:39:55 AM
Thank you let me refresh the account for you and I will do my best to help you.
Sunidhi 9:40:05 AM
Thank you for sharing information please stay connected.
Sunidhi 9:40:33 AM
What do you mean by refresh my account?
A.K. 9:40:43 AM
I mean let me refresh the signals.
Sunidhi 9:41:52 AM

Is it rebooting?
Sunidhi 9:45:05 AM
You are now reconnected with Sunidhi
A.K. 9:45:30 AM
A.K. 9:45:41 AM
Due you see any change in speed?
Sunidhi 9:47:21 AM
Let me test it. Hold on.
A.K. 9:47:29 AM
Sunidhi 9:47:37 AM
A.K. 9:48:03 AM
OKay please stand by let me check again.
Sunidhi 9:48:48 AM
Just did another test 618.1Mb... it's way slower than it should be. My upload speed is also about half of what it is normally. I'm at 19.1Mb when it's normally 32Mb to 41Mb.
A.K. 9:50:01 AM
Okay, can you confirm are you using wireless router?
Sunidhi 9:53:25 AM
I do not use wireless to connect my computers. I told you that earlier.
A.K. 9:53:47 AM
It's not my equipment. I've had 3 different techs and a line engineer to my home a few times a month ago.
A.K. 9:54:31 AM
Okay, let me check
Sunidhi 9:55:52 AM
If I'm only getting roughly half my speed I should only be charged have my monthly rate right?
A.K. 9:57:31 AM
I am sorry
Sunidhi 9:58:21 AM
I am sorry for the issue you are facing right now. xfinity will credit you 22$ in your next month bill.
Sunidhi 9:59:19 AM
What about last month?
A.K. 9:59:48 AM
Could you confirm are you using personal router?
Sunidhi 9:59:49 AM
I'm connected to your gateway.
A.K. 10:00:25 AM
You will be getting $22 for the bill circle march to April.
Sunidhi 10:00:49 AM
I've been dealing with this for 3 months. $22 is all I'm getting for 1 months bill? You do realized I've spent many hours on chat and on the phone trying to get xfinity to fix this problem right?
A.K. 10:01:58 AM
I am really sorry for the issue you are facing and if I would be the customer I can feel the same.
Sunidhi 10:03:39 AM
Okay, but what are you going to do about it? $22 is a start, but that doesn't cover my time on this issue nor does it cover half the bill since I'm only getting half the speed. Giving me a credit doesn't fix my speed issue, what are you going to do about that?
A.K. 10:04:58 AM
Also, I can see that $22 has been credited in your current bill and your next bill would be after the adjustments will be $93.00
Sunidhi 10:05:58 AM
That credit is unrelated! That is because xfinity is giving everyone unlimited data and i'm already paying for it so they're giving people that are paying for it a discount.
A.K. 10:07:11 AM
I can understand and I am doing my best to help you on this and I have refreshing the signals so that you will get the actual speed, however if you have billing concern, we have a dedicated team, who can help you on this.
Sunidhi 10:07:47 AM
We need to talk to 2 people. Billing because as I explained that other $22 credit is for something else. Also an engineer to fix this problem.
A.K. 10:09:04 AM
A.K. 10:12:54 AM
I can understand what you are trying to say, however as I can see from my end the Internet speed is good and checking the modem.
Sunidhi 10:13:51 AM
I am here.
Sunidhi 10:13:59 AM
How can you verify my speed is good when I'm telling you otherwise? What's your proof?
A.K. 10:14:30 AM
If you're saying my speed is good on your end why would you offer me a $22 credit on my bill? You see how it very much sounds like you're lying to me right?
A.K. 10:15:30 AM
My friend is on xfinity 1 city over and he is having the exact same problem. It's not me, it's xfinity. It's also on the xfinity forums that people are complaining about this very same issue. It's sounds like maybe we should all pull together and file a class action lawsuit.
A.K. 10:16:57 AM
How about you connect me to someone higher up than you?
A.K. 10:17:43 AM
I am sorry for the inconvenience, this is the only resolution available from my end and if you want I can raise the ticket from my end so that you can get the actual speed
Sunidhi 10:18:15 AM
If you want I can connect the chat to my supervisor, shall I do that?
Sunidhi 10:18:35 AM
So you just admitted I'm not getting the speed. Yes, connect me to a supervisor please.
A.K. 10:19:10 AM
Sure, please allow me minute, please stay connected.
Sunidhi 10:19:33 AM
I would request you to stay connected as it will take 3-4 minutes to transferring the chat.
Sunidhi 10:23:42 AM
Not a problem.
A.K. 10:24:08 AM
Sunidhi 10:24:28 AM
Hello, My name is Rishab and I am the available supervisor
Please allow me couple of minutes to read your previous conversation.
Rishab 10:41:51 AM
A.K. 10:42:03 AM
As I can understand you are getting slow speed issue
Rishab 10:43:51 AM
A.K. 10:44:10 AM
So are a lot of people. My buddy is on the line with me to find out what is going to be done. He had a tech visit scheduled for a month and now they cancelled it on him. Understandably as we have a quarantine going on, but this problem started before the quarantines started.
A.K. 10:45:18 AM
I have checked your account and it shows that all possible trouble shooting has been done on chat and for further trouble shooting you need to call on our advance technical team 1800-934-6489
Rishab 10:46:17 AM
Why do I have to call and start all over again with someone new? Why can't a ticket be made and escalated? There was a ticket open last time I was on this chat a few weeks ago and nothing ever happened.
A.K. 10:47:22 AM
I am sorry but advance technical team is not available on chat, however I can create a ticket and you will get with in 48 to 72 hours
Rishab 10:47:59 AM
Okay, please provide me the ticket number once you have it.

Router Mode isn't working either for me now.
Had a long wasteful conversation with online chat and the tech 0 lied to me. I got a call back on via text message service and got a nice guy who is sending me a newer model modem than my current device. He said I should have it in a few days. Meanwhile........my node across the street is still at capacity causing drop outs now. I lose internet almost daily and have lag spikes throughout the day.

That would be great, but they keep asking the same cookie cutter questions. I've had several ask me the same questions even after telling them at the beginning of the conversation I'm wired.
Comcast: Are you wireless or wired?
Me: I'm wired.
Comcast: Are you using a the hot spot?
Me: No, I'm wired.
Comcast: Have you tried deleting your cookies and internet cache?
Me: Are you kidding me? Is this dial-up and we're on AOL now?

So an update to my saga.
My old modem was capped at 600Mbps and I could only get 1000Gbps in router mode. In router mode Xfinity kept blocking my clients even though I used port forwarding and even DMZ mode. I could only allow them access for 30 days and what was more frustrating I wasn't getting notified of the block and it took me a few days to figure out what was going on. My modem wouldn't connect anymore in bridge mode for some reason either. I conctacted my line tech on Thursday to let him know the issue. He got me a new modem yesterday(Friday). It worked, speeds were all over though. Upload was god awful. On occassion though I was getting high 800 on the speedtest. He checked the node across the street and he found out it was at 93% for upload. He said that is why the speed is all over. He said he had a meeting today, Saturday, and he'd bring it up. I concacted him about it today and he said Comcast has no plans to do anything about it. It wasn't designed to have everyone online like this. I told him this is Saturday though and all the M-F people are usually home anyways. He said they're not going to do anything. So I contacted Comcast today to try to get a discount on my bill. I can transferred to a technician. The technician said he could fix the speed issue with a new boot file on my modem. Well..........now I'm capped at 600Mbps again which is what started me on this journey about a month ago! He said he's going to escalate it and it should be fixed in the next 24-48 hours and gave mea ticket number. I really have my doubts. Keep calling in and complaining about this issue people or they're going to just keep ignorning us.

So I had a great tech out yesterday. My modem was locked out... Couldn't get into it at all. It was also stuck in bridge mode. They did a factory reset. In router mode I'm over 900. Put it in bridge mode and it won't let any equipment connect to it. Put it back in router mode and I have full speed again. This morning I was getting over 900 still. Went out in the elements and came back this afternoon. Some tests over 900 and others above 850. Seems to be a lot better. We shall see how long it lasts.

I'm having the same issues. I'm only getting 600 speed, but I'm paying for 1Gb.
I just had a line tech come out and checked my modem. He said it's like I'm on the wrong plan. He went to go get me a new modem, but hasn't returned yet. It's been over 2 hours now.
My friend is also having this issue. He took it out of bridge mode and his speed went down to 200Mb. He went back to bridge mode and he's back at 600Mb.
They need to update their phone center and technicians to this problem if it is indeed a firmware issue.
