Let me preface this by saying I'm pretty tech savvy, but modems/routers throw me for a loop.
I am upgrading my internet with Comcast to their 300/30 package. The 150/15 just isn't enough for what I do(Twitch streamer).
I have been reading these forums for the last week or two and trying to figure out what is going to work best for me.
I have one hard wired computer and 4-6 wireless devices connected at anytime. From what I know in the past, a separate modem/router combo is going to give me the most performance and security.
I have been looking at different Arris modems and can't differentiate which one would work best for me. The SB6183, the new SB8200, or an all in one which I would rather not, but if it is more than fine for what I'm doing, then so be it.
I'll be more than happy to answer any other questions as I hope to have provided as much information for you guys to help me come to a good decision on my equipment purchases

[Neutrality] Comcast wants me to pay a premium for data to go to Twitch
I apologize for the length of my post.
I'm a long-time Justin.tv/Twitch.tv Partner and recently began having streaming issues. I can't broadcast to Twitch for longer than a minute without getting disconnected.
All PCs in my house are connected via ethernet to my Comcast modem (CM MAC 68EE963364D6).
I did all the typical things one knows to do in these situations:
- I flushed/released/renewed my DNS.
- I switched from Comcast DNS to Open DNS.
- I confirmed that modem downstream/upstream signal levels were in spec (no codeword errors).
I could access Twitch via http in all of these scenarios, but broadcasting was still impossible. Whenever I tracerouted Twitch, I would see the same timeout errors at 6/30 hops. This did not happen with any other websites I tracerouted except for Twitch and Netflix.
When I contacted Comcast about this issue they told me that everything was working fine on their end, that they do not throttle websites, and that this was likely a node/line issue at my residence (even though I had no modem codeword errors). They scheduled a tech visit, and when the tech didn't show, they told me there was no record of the appointment. When I asked if they could schedule a new one, they told me it would cost $40 ($50 with California sales tax) because "they saw no noticeable errors in their system." After talking to two different supervisors, they finally agreed to send a tech out for free.
The tech checked the line outside my house and was nice enough to explain the readings to me. He confirmed that all was within normal parameters (power level, downstream and upstream signal power/dbmv, signal to noise ratio, etc.). When he went to look at the modem in my room, he was taken aback by my streaming setup, saying he never saw that sort of thing before. I explained to him the nature of my issue, tracerouted Twitch.tv as an example, and showed him my overnight WinMTR results for comparison. The tech politely apologized and said it was all out of his depth, that most of his job involves checking the lines, and that he hadn't done any of this "traceroute stuff" since school. He called his supervisor and asked me to explain the issue to him.
Once the supervisor heard me say "Twitch", he went into a sales pitch for "Comcast Business" and how it has better speeds with no data cap. I told him that speed was not my issue -- connecting to Twitch reliably was the issue -- and I'm nowhere near the 1TB cap in my contract. He went into a detailed explanation about how traffic works for residential areas with high usage, and without coming right out and saying it, strongly implied that a cap on my residential area could be interfering with my traffic to Twitch. I asked if Twitch specifically was being 'throttled' for my area, but he refused to answer that question. I asked if he could guarantee that my connection to Twitch would no longer be 'capped' if I adopted a business plan, but he would only say that "business plans do not have caps like residential plans." The whole while he kept reiterating that if I "valued my business as a Twitch streamer," I should be able to justify the additional expense of a business plan like "every other streamer he's talked to regarding this issue." He assured me he wasn't trying to give me a sales pitch, only a solution -- but it felt more like extortion.
I thanked him for his time, ended the call, and the tech left. Comcast is now unwilling to help me with this issue outside of signing me up with a Comcast Business plan, and I'm no closer to understanding the problem. I have no idea if my traffic to Twitch is being throttled. I have no idea if traffic from my residential area to Twitch is being throttled. I have no idea if a business plan with Comcast would fix throttling, if it is occurring. I currently pay Comcast a little over $100/mo for Blast! Pro alone. If I get a business plan, I'll have to pay a $300 cancellation fee.
Below are my WinMTR statistics and traceroute information for today. I have removed some of the IP information at the beginning out of privacy/DDoS concerns as a streamer.

[Speed] Thinking of Moving To WOW
:( WOW came to my door last night and offered 500/50 for $59.95 mo with a 1 year contract and $69.95 with out.
Called Xfinty about an upgrade in speeds ,there are none!!! This market used to be one of the first to see any kind of upgrade,now nothing!!!
Should I leave and go to WOW??

upstream
talking about the upstream signals,should the upstream power be lower or higher on lower frequencies?wondering this because my lowest frequency is 2dBmV higher than the other 2 frequencies,and does it really matter?

[CustSvc] Comcast..., UGH!
I recently 'upgraded' from slow 12/1 Mbps DSL to 100/5 MBps with Comcast.
But after about 2 weeks, I have decided to go back to the much slower 12/1 Mbps DSL.
Why? I was getting way too many errors (both correctable and uncorrectable) with Comcast. And it was causing problems with my online gaming. For example, in less than 2 days there were 6 downstream channels (16 channels total) with over 500,000 uncorrectable errors (and like 5,000,000 total).
I called Comcast, and they sent a service tech out to check the lines. But all he did was get on my computer and check that it could get online, and run a speed test. Then he announce that there were no problems. When I logged into the modem and showed him the errors, he just said the power levels and the signal to noise levels were all good, so the lines were good. He dismissed the errors as some tech error not related to the lines, line connectors, or splitters.
In the end he said the line are good and he refused to even look at them (which is what he was sent out to do).
Not sure where Comcast gets there service techs from, but this guy was lazy, rude, very annoying, and just plain stupid. And with a 30 day guarantee and only another week until the first bill payment was due, I decide to just drop the service before having to pay the bill.
So, for now, I am stuck with slow DSL until Google Fiber gets installed. (Which strangely they have already wired the building for Google Fiber, and I have had a Google Fiber jack for months. But they will not actually run the fiber in the area for maybe another year.)

[WiFi] Xfinity Wifi Hotspots
Can anyone please enlighten me as to if these are "safe" for general browsing on the Android platform? I'm not real savvy in this area and T-Mobile is rather weak in some parts of NW Houston so this would come in handy if the Hotspot is not a threat. I'm familiar with basic PC stuff but this isn't one of them. Do I need a VPN & if so, which one?
Thanks

[Equip] Is there a Recall on Cisco 3941T?
Read something about a Recall in Offical Comcast Forums, just got this modem on September 2nd from Comcast Service Center? Do we have to go back there to exchange for a Arris Model? or will they be shipping us one if there is a recall on the 3941T
↧
uncorrectable errors?
Hi,
is this number of uncorrectable errors reasonable? it's over 3 days! I had removed an upstream splitter that brought my power levels to like 7mdbV. i put it back in on monday and pushed the power levels back to where they were originally ~0mdbV.
the router is a cm600. last column is the uncorrectables, next to last is correctables.

[Plan] Side Discussion on DOCSIS 3.1 Gigabit service
Mod Note: This topic started as "XI Gigabit DOCSIS 3.1 - data cap with 3-year agreement?" It has become a general discussion of this deployment, hence the title change. uid://455626
If you actually have had this service installed, the stickied report topic is here. > https://www.dslreports.com/forum/r30960001-Speed-Report-DOCSIS-3-1-Gigabit-Service-Here If you report, please include info requested in the first post and keep that topic strictly on topic. Thanks, sortofageek
The XI Gigabit DOCSIS 3.1 is now available in my area. I am tempted to sign up. Early reports said unlimited data with a 3-year agreement. The Comcast website says nothing but the typical disclaimer about the data usage plan. I don't want to sign a 3-year agreement for a plan with a data cap. Does anyone know if the XI Gigabit service is subject to the data usage nonsense?

[E-mail] Unreliable Comcast email past week or two (acting up again 3/9)
Has anyone noticed issues with the Comcast email the past week or two? As of Thursday morning (3/9), it is very flaky. Sometimes it will work, sometimes not. This is webmail, Connect app, or Thunderbird (via POP3). This has been happening on and off for awhile now.

[Speed] Blast Pro 200/10 only seeing 100/12 actual
Hello,
I was on Performance Pro (100/5) and was seeing 105/5 mbit (provisioned 121/6). I needed more US so I changed to Blast Pro (200/10). Speed test then shows 105/12, the same DS!
At my previous house I had an older 100/10 plan that ran at 120/12 on my same SB6120 and router.
I have a Motorola SB6120 and WNR3500L with gigabit LAN to computers.
I thought maybe the 4 DS channels was limiting me in this node, so I bought a new Zoom 5170 16x4.
With the Zoom 16x4 I am getting the exact same speed of ~105/12 mbit.
The config file says BlastPro.
All modem lights are on (blue US and DS, green LAN gigabit) and it appears to be bonded to 16 channels, but it would appear to be using quite a few less than 16 since I saw no speed increase from the 4x4 modem I was using previously.
Have a reputable HSI splitter (only one ahead of modem), and I have very few errors and OK signal strength. I did replace the coax from the wall to modem and it brought the errors to near zero from previously high numbers.
Tonight I will try moving my modem to connect directly to the incoming drop to the house. Beyond that I don't know what to try...

[Connectivity] New network created? named network 2
I turned my computer on today after getting home from work and noticed windows created network 2 as I can no longer connect to my previous network which is just called network. The computer is hard wired with no option for wifi. Could this have been caused by my isp? I contacted them earlier and they did tell me a network outage occurred a few hours ago. I went ahead and deleted the old network and renamed network 2 back to just network. Any help would be much appreciated. Thanks!
I should mention i'm using Comcast.
-Update: I've contacted comcast tier 2 and basically they are suggesting I factory restore my modem/router since I've also noticed issues with the wireless gateway comcast offers.

I visited Xfinity. there was a promossion 39/mo for 75 Mbps and an agents suddenly appeared
many time I declared that I cant pay so much dont lease modem but at the end suddenly price was changed and became 49/mo. I tried to contact the agent and he suddenly disappaered
I thought modem was included. But learnt that not inlcuded
Today they sent a sorry message that double charged mony "I'm writing to let you know that due to a processing error, our payment vendor charged your credit or debit card twice for your recently authorized payment. "
I talked them many times but everyone pass me another agent who do not know what to do like a tennis ball
5 email message i received. nobody sent me my account number and i could not access my internet account too.
I entered my phone number but the system never could sent messages to my phone
The company is like a swamp : money oriented
I pay double 49/mo for 75 wihout promossin and modem

[Signals] DS channel aquisition question
Does it matter that my modem is selecting the 729000000 Hz for the start-up "acquire DS channel" when there are higher frequencies, please ? This has happened twice in the past 6 weeks: about 4 weeks ago when I power-cycled, and then yesterday after we had a 24-hr electrical outage. I had turned off my PC prior to that but not unplugged.
MODEM: Zoom5341J
Connection: wired; no router other than Vonage adapter
Location: greater Grand Rapids, MI area
I've not noticed any connection issues but just curious. Thanks very much in advance.

[Business] Business account, Comcast disconnected internet for no reason
I have been a business customer of Comcast for about 5 years. Yesterday my internet stopped working, and it turns out they disconnected my internet. Apparently my coworker returned a small digital TV converter to a store, and the store thought it was a business router and cancelled my service.
I have been on the phone all morning and no one can help me - I basically want them to just turn it back on. The modem is still installed and online (they acknowledge that they can see it) but they all claim there is nothing they can do except set up a new service install for me with a brand new contract and new equipment, which seems insane. I have tried talking to tech support and retention.
I am not sure how much detail to post, but if anyone works for Comcast and can fix my account that would be really appreciated. My original support ticket that should have all my account information is:

"Plant Noise"
I jacked that other thread, so I figured it was best to start another thread because this is going to get messy again.
This is the album where I've been collecting pictures: http://imgur.com/a/0TDuL
Here are my stats after the tech left:
[att=1]
Narrative: I opened the door and the tech recognized me from 3 years ago when he did the install. Good guy, willing to answer any questions, but that's as far as it went. I told him that I'm still using all his original cables and terminations. Immediately after opening the door he said he was going to check everything out and there's no reason to come inside. I confirmed what his WO said and he said "It's dropping out" and I said well not exactly and clarified that I get intense, intermittent periods of dropped packets. The connection is still active, but websites get slow to load and the packet loss approaches 40%.
The *I*N*S*T*A*N*T* I brought up my upstream SNR, he shut me the fuck down. It's "plant noise". This triggered my memory and I remember going through this with him before. So, I hate to say I told you so, but this tech visit went exactly how I expected.
I think the "plant" here is maintained like garbage. I've always had these issues and have been down this road before. When I left to run MY service call, he was replacing the grounding block in the box. That's when I asked him for a grounding strap because I just made it worse and he laughed and said they have improved ones now. Looks the same to me, maybe him just being nice because I couldn't get it on? There was no way to get it tight because he cut the excess strap off. Whatever, I don't care, I understood why and appreciate his attention to detail.
He said he's putting me on a "watchlist", great, just what I need; to be put on another watchlist.
So what's next, boys? He wasn't interested in chatting so I was too apprehensive to even ask him for an attenuator.
