Hey everyone,
I have a zoom cable modem 5341J modem and a Asus ac-68u wifi router. For about the last month I have been getting my proper download speeds but my upload has only been 1mb to 3mb. I have called xfinity 3 times, The first time the lady sent a reset signal and that helped for about a day. The second time I called back with the same issue a day later, they sent out a tech. The tech found nothing wrong with lines, he directly plugged into the modem with his device and did a speed test and saw my proper download but upload was only 1mb to 3mb and was suppose to be getting 10mb. So he said there was nothing else to do. I talked to a few other friends and tried a new modem and router to rule those out. At first they worked great! Then 3 days later I was in the same boat. So I thought okay lets go direct from modem to just one pc via eithernet and only use eithernet now so everyone knows and same boat. Still slow upload speeds. I have done a lot of reading and can't figure out where to go next to figure this out. Anyone else having any issues or insghts to my problem. I also read that I could open cmd in windows and type ipconfig/release then type ipconfig/renew This helped for about 20 minutes and right back down to 1m upload. My mind is blown for now. Any insight or help would be great from you all. Thank you.

Latency spikes, 5% packet loss, Unsure Upstream signal levels
I've been having Latency issues with Comcast/Xfinity for almost a year now.
Started around Spring time of 2020 and started to get really bad around summer, now winter is here and its 2021.
Originally I had a cm700 modem with Two X1 boxes and two standard digital setup boxes with SD channels (i.e. ch 4 - 72)
So typically I had a 4 way splitter installed by Comcast. 1 direct line to modem. 1 direct line to X1 primary box. 1 direct line to secondary X1 box. 1 direct line with a 2way going to the SD setup boxes.
For the past year I've been getting Intermediate packetloss its not huge or anything roughly around 5% to be fair. I've used ping plotter and regular ping terminal -t usually ping the Comcast servers.
I also get ping spikes as well highest I've seen was around 300ms.
I've had a guy come out and check my lines and replace some with the new R6 cables I think they was called, and each time they say my signals appear to be good and then replace the 4 way splitter.
Had one guy do a 2way into a 3 way with the modem at the 2way from tap and then the boxes on a 3way attached to the 2way each time a different guy came out they had different opinions.
Now to my understanding downstream is best between -8 / +8 best is closest at -0 or maybe it was -8 / +5 but that is considered perfect for downstream from what I recall them saying.
But as it comes to the upstream I'm not quite sure what the range should ACTUALLY be at to be honest. I think is where my issue might be. ( my downstream is fine btw )
I was on the phone one night for 3+ hours with a Comcast guy that pretty much said there is nothing they can do...the signals look fine and its prob my modem, and since I own the modem they can not look at my signals or get in to the modem and to see if the firmware needs updated, and I should maybe try a different modem.
Well I now have 3 modems now one is a DOCSIS 3.0 the cm700 I bought two DOCSIS 3.1 modems as well to test. T25 and SB8600.
So my main question here is what would the better setup be for a modem the standard 4 way splitter or a 2way with one to the modem and the 2nd to a 3way for the cable boxes?
Also what would be the actual best upstream signal for no packetloss or latency issues. I've read that 3.0 and 3.1 modems have a different range low of +35 to +47 max depending on 3.0 or 3.1
I notice with the different splitter set up I get different readings for the power levels in dBmV so curious to what upstream signal I should be aiming for the two way gives me around +47 upstream and the 4 way gives me around +50. So which is better??? I also hear from some old Comcast tech guys that I could try to use a coax drop amp but not sure which to buy if so because there are so many...passive return active return zero signal loss etc...I just want my latency issue to be fixed as I've tried tech support on Comcast and called in so many times and had guys show up and nothing has corrected the issue with my internet at all.
Now I will say the 3.1 modems seem to be better IMO and 3.1 seems to only work on the downstream from what I can tell. it lowers my ping by about 5ms and also has good bufferbloat with the AQM implemented in DOCSIS 3.1 but as for the UPLOAD on 3.1 I'm getting huge spikes in the loaded latency on my uplink with 3.1 and IDK WHY like massive bufferbloat I'm guessing AQM does not work for upstream and that kind of sucks because even tho with 3.1 the download is great and ping is nice once you use any of your upload speed at all even a little bit of it you get a lot of jitter and the loaded latency increases the ping by 80ms I've seen it spike up to 150ms but it balances out down to around 40ms after time. kind of worthless to be fair I might just go back to the cm700 3.0 router unless I can apply SQM with a special router down the line but I digress.
All testing was done with the modem connected to a single PC with Cat-8 Ethernet.
TL:DR What is a ideal signal level I should be getting for my Upstream. As I know this controls the latency ping mostly. I know its a range but I'm looking for perfect range here that I should be getting on my DOCSIS 3.1 modem so I can correct my latency spikes and packet loss issues finally as nothing the services guys have done corrected this issue.

[Speed] Modem reboot, now low speeds
It appears my modem rebooted last night. I am on the Gig tier and my speeds were 940+ down via the speedtest Windows app. I am now getting between 400-525. My modem is a Netgear CM2050v and the signals look good. Did they screw-up and send me the wrong config file?

Netgear CM2000 vs Arris S33 vs Motorola MB8611
I know these 3 modems are fairly new, especially the Arris S33. I notice they all have a 2.5gb ethernet port, which I like for future proof. I am upgrading to a 1 gigabit internet with Xfiniy/Comcast.
Netgear CM2000 - $249
Motorola MB8611 - $169
Arris S33 - $169
Why is the Netgear so expensive? I don't mind buying the CM2000 but I would really like to know first if it's even worth it. Is the chipset different in each of these modems? Not sure which one to get.

Data Usage Meter Broken?
Anyone else having issues checking the data usage meter? When I click on the link nothing happens. I can only get the chat bot to tell me what the usage is. Last month I went over and it looks like this month I will as well. However, I never got a notification, charge, etc.
I was chatting with support and they were not able to look up my usage history either.
We have 3 college students and myself working full time remote, so I'm sure usage is high. I'm just trying to see if I need to purchase unlimited data.

Will Comcast and AT&T drop Fox News and NewsMax...
Like the looney liberals want them to? I'm surprised they haven't already since Comcast is liberal owned. Before anyone mentions "a bridge too far" or ratings, liberals have no idea what the former means and care more about politics than the latter(CNN and MSNBC, whose combined ratings =Fox News' ratings, are exhibits A and B for that).
Does Comcast have OAN? Its not in my line-up. I've heard they same thing about them.

[Speed] What markets still can't get gigabit?
We still have no DOCSIS 3.1 here in Northeast TN and are stuck on a 550MHz system. The only upgrades we get are the price hikes (which Comcast says are partially justified by having access to the "nation's largest Gigabit network"). Besides Northeast TN and some areas in rural Michigan, are there any other Comcast markets that still lack access to gigabit speeds?

Gig/2Gig > fiber?
Recently had Node+0 work completed in my area. Since then I see both Gig and 2Gig service available.
Is this with fiber or still coax, just Docsis 3.x?

2 routers connected to xb7 possible?
On my old att connection I had two routers connected to our modem (one for my stuff, the other for the rest of my family). Is this possible with Comcast? I read in another post it would only assign one WAN IP? Maybe I read it wrong.

[NEWS] NJ State Senators File Complaint Against Comcast
In this time of Work from Home, School from Home, and just quarantining at home, Comcast caps the Internet!
Here in my local District of NJ, across the river from Comcast Headquarters in Philly, our local State Senators are taking action!
Maybe other States will follow suit and let Comcast know that this ISN'T ACCEPTABLE at this time! :mad:

Comcast Aims for True 1-gig Over WiFi Experience

XB6 - What is going on with 160 MHz Channel Bandwidth?
I had my XB6 replaced a while back after contacting support because WiFi settings were no longer accessible. They sent me a replacement modem to fix the issue, although I knew the modem wasn't the issue. The replacement was supposed to be an XB7 but another XB6 was shipped instead. At least the replacement wasn't locked out and we were getting approximately 600-900 Mbps with control over the WiFi settings.
Recently, the WiFi speeds have dropped down to a peak of 300 Mbps. Now the gateway's settings are not disabled, but not matter what I select for manual settings the gateway always goes back to Channel 44. For the bandwidth the 160 MHz continues to show selected but the clients are connecting at 80 MHz.
I found a post on reddit saying the blocked settings were part of the xFi Complete package. However, I don't have the xFi Complete package.
Is there any solution other than getting my own equipment? I know that's a popular option on here but I've come to like the simplicity of the setup, especially that it works really well. At least when comcast doesn't muck it up.

How are my signal levels? (Gigabit - speeds inconsistent)
I had my service installed Monday and i've been able to get around 940 Mbps down sometimes, but other times i'll only get around 300-500 Mbps. I think from my research these signal levels look good? If this isn't the correct information please let me know and i'll look elsewhere in the modem stats. (Sorry these arent sorted better, I couldn't get it to copy right, but each category is in the same order as the channel index)

I get this every time I try to test. Sometimes it will eventually work, but always after at least a few errors.

Modem reboot
I’ve been having extremely high uncorrectable errors on frequencies 621, 627, and 633. My power and SNR numbers were also not great. Rebooted/unplugged my modem multiple times and replaced various cables to no avail. Yesterday I logged into my Xfinity account to check the status of my connection and used their modem reboot function. This resolved my uncorrectable errors and power/SNR issue. I was under the impression resetting the modem by turning it off/on was functionally the same as Xfinity’s reboot. I guess I was wrong.

Comcast says they can't update my Modems firmware?
Hello again,
I have a question. My brother has a Motorola MG7550 modem that we purchased years ago so we wouldn't have to lease the modem. Today when he was looking at tier speeds I asked him to get the tech to make sure it was running the latest firmware and my brother told me that the tech told him that they do not provide firmware updates for non leased modems. Is this true, because I have a very hard time believing that.
Thanks for any advice you can give us.

[WiFi] Suggestions for buying my own modem so that I can disable 5Ghz?
Hello,
Because of my home theater setup I need to disable 5GHz from the router provided to me by Xfinity. This is because the wireless rear speakers are cutting out when the router is on. Unplug the router, wireless rear speakers work fine. Turn on the router: rear speakers cut out.
Since Comcast/Xfinity does not allow for disabling 5Ghz, I cannot use my home theater.
I'd like to purchase my own modem, but the combo modem/router from Comcast/Xfinity will continue to broadcast 5Ghz wi-fi signal in my home, making the wireless rear speakers from my home theater useless.
Can anyone suggest a combo modem/router so I can plug in coax from Xfinity and disable 5Ghz?
Thanks,
Murph
