What's the current "latest and greatest" gateway offered for X1 customers?
I currently have the Arris TG1682G, but I'm wondering if there's a newer version. Thanks.

[Speed] Moto MB8600 + Linksys EA8500 != 200 Mbps over Wifi?
Hey guys. Going on week three of my new service and still having issues. Would love your help if you think I am missing anything really obvious?
Paying Comcast for Premier Bundle + Blast upgrade to 200 Mbps (actually it is supposed to be 250 I believe)
First tried a SB6190 but never got beyond 100 Mbps...
Switched to Motorola MB8600 and fully bonded 24/4 (see attachment for connection details). All is well there.
Wired to Linksys EA8500 (also labeled as AC2600) with ethernet in-wall to a Gigabit switch (TV, PS4, AV)
Wifi 2.4 to most phones, Google Home and 5 Ghz (hidden) on my primary laptop
First test on ethernet when the new modem woke up verified 200 Mbps coming from Comcast
Now I am trying to get decent throughput via Wifi to ANY of my wired or wireless devices
Guest access is OFF
Media prioritization is OFF
Parental controls are OFF
Multiple speed tests have yielded between 30 and 90Mbps only (Ookla built-in to router admin, speedtest.net, Xfinity speed test, Xfinity BETA speed test).
I have checked everything I know to check and I am puzzled why I can not get beyond 90 Mbps even on a wired connection through my router. While 80-90 is definitely a "first world problem" I was getting lots of blips last night while streaming 4K UHD video to my beautiful new Sony Android TV, which is why I am paying for 200-250 to begin with!
Any advice/guidance?

[Signals] Packet Loss - Signals look fine & Arris SurfBoard SB8200 modem
Exactly 3 weeks ago on June 8, 2017, I replaced my Arris SB6190 DOCSIS 3.0 modem with the Arris DOCSIS 3.1 SB8200 modem, I have been having timeouts browsing the internet as many connections will timeout and require that I reload before it will work properly including posting here where I hit the Post Now! button, it just will say waiting for connection in the browser for 1+ minute until I hit Post Now! again before it will post. Even with speedtests, I was getting 50Mbps down/11Mbps up most of the time and about 5% of the time, it will be somewhere in the 140Mbps down/11Mbps up range. This is on a BlastPro 200Mbps/10Mbps connection here in Comcast San Francisco, California. I have already resetted the modem to factory defaults and have tried directly connected via Gigabit Ethernet using CAT6 cable to a computer with the same results. I had confirmed with netcool within 2 hours on the same day I began using the modem and he said it was provisioned correctly and the signal levels look good. The SB6190 did not have the same issues but the speedtests were 80% in the 180Mbps down/11Mbps range but that was when it was running on 24 channels down/4 channels up. Now it's 32 channels down/4 channels up and 1 DOCSIS 3.1 down channel. And we all know the SB6190 has other known issues that the SB8200 does not have. Even on this side, as I have posted status pages before, the signal all looks good even though it reports a T3 timeout about once every 2 days per the error logs.
So on June 15, 2017 - I wrote on the Comcast Direct part of the Comcast/XFinity forums here on DSLReports.com describing the problem and the response was:
"Hello {first name} looking at the signal on your modem I confirmed there is a high amount of resets and highT3 timeouts count which can be related to a RF problem can you please confirm connections from the back of the modem as far back as you can. Thank you"
All the connections look fine to me as there is the underground cable from the underground tap which is in the private street in the back of the house to the grounding block at the back right corner of the house and then cable from the grounding block going up the roof and then down to the left front outside wall of my living room going into the coupler and then the cable directly to the modem. The coupler and cable directly to the modem was professionally installed by a Comcast Business Internet contractor in February 2016 before I switched to Comcast Residential High Speed Internet. Everything before the coupler back to the tap is atleast 10 years old if not longer.
I wrote back and basically the Comcast representative did not respond until 4 days ago saying there has been a huge increase in T3 timeouts and they like to send a technician to check the signal which was scheduled for yesterday at 1PM-3PM.
The technician arrived yesterday near the end of the appointment time window at 2:50PM and first checked the signal from the modem which looked good but was on the telephone with his manager who said there were 100s of resets during the past 3 days while it only shows 2 in my error log so they checked the signal again at the outside of the living room wall and then at the grounding block where the underground cable from the underground tap comes in and they all look good and then we went to the underground tap which feeds 3 houses, mines and my neighbors and basically, instead of the wires deep, it was all on top of the solid dirt and it appears one of the ports on the tap is broken so what was done was the following:
The cable from the grounding block in the rear right corner of the house going up the roof and down the left front outside wall of the house was replaced with a new one and the old one was removed while the coupler was also replaced. I do not have a photo of what it looked like on the grounding block side before the cable was replaced. He had a fellow co-worker came over who agreed that the broken port on the tap could cause ingress even though the signal looks fine. So what is being done is that Comcast Construction will fix the tap as soon as today while they will run a new underground cable from the tap to the grounding block, the later which will take about 7 business days. Now a question, is there a such thing as a defective grounding block since I thought if it is old, it might not pass all the frequencies.

[Speed] Bufferbloat Solution?
I've been trying for months to find a solution to the bufferbloat problem on my Comcast Internet service. My service is nominally 100/5 Mbps down/up. Using my own (Netgear CM600) modem and (Ubiquiti EdgeRouter LITE) router, it has consistently tested at ~118/~6. However, the bufferbloat rating is always either D or F.
I then began trying the built-in QoS in my router. Using the EdgeOS Smart Queue option, I started with down/up limits of 100/5 and got speed results of 71/6, but with a bufferbloat rating of B.
Setting the upload limit at 6 or 7, I gradually moved the download limit up to 110,120 & 130 and saw small increases in download speed with each step - up to 86 Mbps with the limit set to 130.
I then set the down/up limits to 500/12 just to see what might happen. I got the results shown above. I retested with these settings about five times to be sure and the result held steady. In each case, bufferbloat stayed at B.
I am certainly no expert in network technology, but I'm very happy with these results - the best I've seen with this Comcast service.
I'd appreciate any comments. Perhaps I'm misinterpreting the results

[Connectivity] SB8200 Signals. Is this normal or bad?
Around July 17th I am now getting constant disconnects and usually happens out of nowhere and happen at any time. In looking at my signals I have noticed a Channel 159 and it has a huge number of Correctable and Uncorrectables.
Is something wrong with my line or modem?

[Connectivity] Comcast issues with sb6190? packet loss
Hi there, new to the forums here.. since about 3months ago I've noticed weird things going on for our internet, we had a big storm come through around then. We first thought our old SB6121 modem had it's run since owning it from 2012, bit of logs and such would pop up often each day every few hours, etc. We took this chance to go buy a brand new arris sb6190 modem and also replaced our old router with a netgear n900.
Things seemed better for staying stable and not losing connection at all now, but I was still having packet loss in games that I never had before even with the old hardware.. I double checked the settings in both modem/router making sure nothing is holding either back aka firewall, QOS service, etc. My next thing we had done was have two techs come out and double check our signal levels, noise, etc. replace coax cables with new ones and even separate our coax cables from the cable box so one is directly for tv services (which we already canceled our tv services) and the other one is directly for internet.
After we canceled our tv service we had an offer to boost our internet speeds from what they were before (125mbps down/24mbps up) to (180mbps down/24mbps up). So after all of that I was still getting rubberbanding in games at times, latency and packet loss. I ran tests to figure out if it's an issue in house or something with comcast or if it's towards the games servers.
I'm now getting information from a tech saying that the modem we now have has a bad chipset/processor and is suppose to be known for screwing people over on packet loss but I'm not sure if that's true with my case or not based on what info I have.. I just bought this modem a month ago so I'd rather not have to replace it with something else in less I knew that was the major problem here, otherwise I'm out on more money and with no new results. If I do need a new modem because these sb6190's are faulty or something.. is netgear cm500's known to be in good history with comcast?
Above is a bit of pictures of our modem info, some tests I've ran for the last week or so.
I live in northern IL, provider is comcast. willing to provide extra info if needed.

[Connectivity] netgear cm600 Having packet loss while gaming
Hi there, I recently made another thread about a week ago explaining that I was having packet loss issues while gaming and I was told to replace my sb6190 modem since it is known to have issues. I'm going to list everything I've had done so far below in order to fix this. Before listing all the fixes I've done, our setup goes as follows.. street cable box coax cable -> 3 way splitter -> coax cable through F to F grounding bridge -> coax cable to modem.
replaced both modem and router with brand new store bought ones (sb6190 and netgear n900).
had first tech come out and double check the lines, replaced old coax cable leading from splitter to modem and replaced the splitter with new one.
had second tech come out and double check the lines, by the time he left we had the setup listed above now.
Tried calling comcast to see if possible for a tech to monitor our network for 24-48hrs but they did a 5min test from their end "everything seems fine".
Was told that the sb6190 modem is known for issues like this and returned it for a netgear cm600 modem in it's place.
Now we're caught up to today, I'm still having packet loss issues when I play final fantasy xiv but my ping to google doesn't seem to change ms or lose packets. (I have yet to test another game during the timeframe when ffxiv acts up)
below is my recent pings and tests I've ran today..

top is ping to ffxiv data center in cali and below is google. Did a tracert test to the ffxiv servers while it was acting up also.
»/pingt ··· /3438873 (ran this while there was issues)
I also have listed below the timeframes of when my ms in ffxiv goes from avg 70-80ms to 90-100ms and begins losing packets.
(note that after the end time frames the ms slowly begins to even back out at 70-80ms again)

(side note the only pattern I see is that it's roughly 20mins it lasts each time, along with being stable for one hour in between)
I have no idea what else I can do to fix this issue.. My last things I have yet to do is remove the splitter (have a -6db attenuer piece in the mail already so I can use that instead of this splitter). I can try having a tech come out and install a new coax cable leading from the street cable box to our house to replace the one in the ground right now. Lastly I could replace our ethernet cables.
I'm willing to try anything at this point, the thing is I never use to have this issue happen ever in the 2-3 years we've lived in this area. The only thing I can link any of this to is about 3-4 months ago we had a storm come through and it seemed like ever since then we started seeing issues, which is mainly why I replaced our old modem and router thinking they got messed up during the storm or something else, etc.
I also have downloads of 180mbps and uploads of 24mbps, I have QOS service on for my router but it only covers upstream control.. should I just turn QOS off completely? We have 3 computers, 3 phones and 1 tablet connected with one game system at most.. our computers are plugged into the router with ethernet cables.

Half Upload Speed
Hello, all!
Over the past two months or so, I've been getting just about half of the upload speed advertised on my plan (150Mb/s down over 20Mb/s up; Comcast Xfinity; South Florida Resident).
I used to run an SB6141 through a Netgear AC5300.
Because of the upload speed issues, as well as intermittency in the connection in general, I upgraded to an SB6190 and a Linksys Velop mesh system.
The intermittency and slow upload continued, so after doing some research and figuring out that the SB6190 had a bad chip, I upgraded to the Netgear CM1000 modem.
I've had a handful of Comcast techs come by to check the lines outside and the coax running through the house, to help optimize the network. We returned their all-in-one terminal (we used only for landline) and shut down the landline completely, just to limit the amount of ISP devices at this residence to only the one CM1000 for internet as well as two TV set top boxes.
The connection intermittency is now down to a minimum. At this point, the connection sometimes gets dropped randomly about once every 2 hours for about 10-15 seconds, but I suspect that's more due to the Linksys Velop acting funny (new product, frequent firmware updates).
That said, the upload speed (despite *everything*) is STILL stuck at precisely half of the speed advertised.
If it helps; running speed tests via direct ethernet to the modem yields relatively inconsistent but acceptable latency (8ms-24ms), reliably dependable download speeds (160-180Mb/s) and *consistently* halved upload speeds (9-10Mb/s).
I've attached channel info via the Netgear CM1000 web interface.
Any help on this at all would be greatly appreciated!
Thank you in advance :D

[Other] Unable to ping/traceroute most websites outside of Comcast
Today I'm having problems reaching TiVoCommunity.com, despite a down detector web site saying it's up, so I decided to do a ping and traceroute. Both failed, stopping at be-33659-cr02.ashburn.va.ibone.comcast.net. I tried google,com and got the same thing, though Google's web site is reachable. I tried traceroutes to a number of other various web sites and most failed. The only ones that work are ones that don't go through be-33659-cr02.ashburn.va.ibone.comcast.net. It looks like that router is filtering out all ping packets.
Anyone else seeing this issue?

[Speed] Moto MB8600 + Linksys EA8500 != 200 Mbps over Wifi?
Hey guys. Going on week three of my new service and still having issues. Would love your help if you think I am missing anything really obvious?
Paying Comcast for Premier Bundle + Blast upgrade to 200 Mbps (actually it is supposed to be 250 I believe)
First tried a SB6190 but never got beyond 100 Mbps...
Switched to Motorola MB8600 and fully bonded 24/4 (see attachment for connection details). All is well there.
Wired to Linksys EA8500 (also labeled as AC2600) with ethernet in-wall to a Gigabit switch (TV, PS4, AV)
Wifi 2.4 to most phones, Google Home and 5 Ghz (hidden) on my primary laptop
First test on ethernet when the new modem woke up verified 200 Mbps coming from Comcast
Now I am trying to get decent throughput via Wifi to ANY of my wired or wireless devices
Guest access is OFF
Media prioritization is OFF
Parental controls are OFF
Multiple speed tests have yielded between 30 and 90Mbps only (Ookla built-in to router admin, speedtest.net, Xfinity speed test, Xfinity BETA speed test).
I have checked everything I know to check and I am puzzled why I can not get beyond 90 Mbps even on a wired connection through my router. While 80-90 is definitely a "first world problem" I was getting lots of blips last night while streaming 4K UHD video to my beautiful new Sony Android TV, which is why I am paying for 200-250 to begin with!
Any advice/guidance?

[Connectivity] T3 Timeouts and Upstream Signal Strength
So I have been having issues with my signal dropping out for about the last two months and I am getting pretty frustrated with Comcast technical support it figuring out what is going on.
Chaska, MN
When streaming trying to stream video whether by wi-fi or hardwired (tried desktop pc, tv streaming apps, blu-ray, chromecast, ipad) I start having connectivity issues. Sometimes it comes back on and other times it will not resolve unless I power cycle my modem.
It is intermittent, but primarily seems to happen when trying to stream video or audio.

Hardware Version 3

I have noticed when looking at the modem logs that it is continually a T3 timeout.

I checked the power levels to see if there was anything there that was causing problems. Initially the original modem that I had (Motorolla SB6141) was showing normal Downstream signal levels, but Upstream levels were all 29-31 dBmV compared to the recommended approx 45-55 dBmV. When a Comcast tech came out to the house, he said that the power levels all showed fine and that with Comcast, their system had power levels of 30dBmV, so my numbers were actually normal. The tech mentioned that my modem was actually end of life and that my modem (which is an 8 channel modem) was actually only running 6 channels and that was the problem. I know I had had the modem for a while so I just have now replaced the modem with with a SB6190 with 32 channels, but I'm still having the problems. Here are the current levels...

What's strange, is that when the modem is acting up, it seems that my upstream power levels are actually closer to 45dBmV, so can that be the issue? Comcast keeps indicating that it is my equipment, but I've now replaced both my modem and my router with no issues. The cable comes straight out of the exterior wall and goes to my modem with no splitter. Like I said, I've tried wired and wireless, numerous streaming devices. I just have no idea what to do or how to get Comcast to admit it might be on their side. HELP!! PLEASE!!!

[Mobile] "Xfinity Mobile" wireless service
As mentioned in this recent DSLR news item https://www.dslreports.com/shownews/Comcast-Prepares-For-Mid2017-Wireless-Service-Launch-139048 , Comcast is planning a mid-year launch of their wireless service.
Comcast announced today that they will be providing the details on this new service on Thursday:
Comcast to Host Analyst Event to Discuss Launch of Mobile Initiative
Comcast press release, Business Wire - April 3, 2017
http://www.businesswire.com/news/home/20170403005198/en/Comcast-Host-Analyst-Event-Discuss-Launch-Mobilequote:On Thursday, April 6, 2017, Comcast will host an analyst event to discuss the details of its previously announced mobile initiative, which utilizes an existing MVNO agreement. Senior members of the Comcast leadership team will participate in the event. ...There is also this FierceCable article today about it:
Comcast sets Thursday meeting with investors to discuss wireless launch
By Daniel Frankel, FierceCable - April 3, 2017
http://www.fiercecable.com/cable/comcast-sets-thursday-meeting-investors-to-discuss-wireless-launchquote:Some of the telecom industry’s most closely guarded secrets could finally be revealed Thursday, when Comcast hosts what it calls an “analyst event to discuss the details of its previously announced mobile initiative.”
:
Comcast confirmed plans to launch a wireless service combining the strengths of its vast Wi-Fi network and its MVNO deal with Verizon back in September. The launch has been slated for sometime later this year.
:
Last week, FierceWireless reported that Comcast is quietly partnering with Apple as it prepares to launch wireless service under the brand Xfinity Mobile: http://www.fiercewireless.com/wireless/comcast-quietly-taps-iphone-ahead-launch-xfinity-mobile
The cable giant’s name has been added to behind-the-scenes - but publicly available - code that lists carrier bundles for the iPhone. The list of carrier bundles is used by iTunes and iPhones to determine whether the iPhone’s SIM is supported by a service provider with whom Apple has an agreement, then provisions the phone accordingly.
The iPhone's latest list of carrier bundles includes "Verizon_Comcast_LTE_US," and mentions the service "Xfinity Mobile." A source pointed out the reference to FierceWireless, and a different source with knowledge of the matter confirmed that Comcast has indeed partnered with Apple ahead of the launch of Xfinity Mobile.

[Equip] Should I get a CM600 or TC7650-E to replace a Motorola 7420?
Recently stepped up from a ultra reliable 8x4 Zoom 5345 to the 16x4 Motorola 7420. I've had it for a week or so and it is proving to be just as reliable compared to the Surfboard 6141 I've owned before.
I never knew much about downstream channels until I did some Googling and courtesy of this site I see that 24 downstream channels are available in my area. When I look at my Motorola's GUI interface I see that channels 9-24 are bonded iirc.
Couple of questions...should I step up to a 24x8 modem to take advantage of the extra 8 channels? Right now my speeds with Blast are about 233 down and 12 up. Will those extra downstream channels make a noticeable difference? I imagine not in speed but maybe extra pipes help in congestion?
Thanks in advance for any advice if it is worth it to make the change to a 24x8 modem

[Mobile] Mobile slower then verizon
two iPhone 7's side by side both on verizon network with LTE working... xfinity mobile speed tests at 7.4Mbps down ant 1.1Mbps up.... Verizon tests at 28.2Mbps down ant 5.1Mbps up (averaged over multiple tests)
I thought there was suppose to be no speed difference? I think there is prioritization in place for verizon traffic, but these are tests over multiple days and different times of days averaged I never saw xfinity mobile go over 8Mbps down
