    I've been back on Comcrap since mid-2011.
    Yep. FWIW, I've been using an Asus RT-AC68U since late 2016 just fine. It's connected to my TiVo Bolt+ and was previously connected to my TiVo HD.

    It replaced an old Westell 9100EM that I retired that I received from Verizon (in 2009!) when I was on FiOS in WA state. It seemed like it was no longer supported so no more firmware updates. When I had that, I was using a TiVo HD with it for many years.

    I'm using a Motorola SB6141 cable modem that I got for free from either someone at work (most likely) or someone on Nextdoor. I started w/a customer owned modem on Comcrap with a Motorola SB6120 that I bought from Amazon in 2011. I had to rent a modem for a few weeks until I received it.

    FYI at least here in VA, Performance Pro service is 150Mbps down and 5Mbps up (usually 170-180Mbps down and 6Mbps up measured). This is with an older SB6141 (DOCSIS 3.0 with 8x4). We're in a small town of 24,000 and we don't have any issues with congestion here.

    I have the same one. And I'm in Middlebury, VT with zero congestion too. I get excellent performance!

    Based on Amazon, the 3 major D3.1 modems are $160-$180.

    What is your advertised speed? It appears that for most regions that's 150 or 200, which would be provisioned at 181.5 or 242, respectively, which a 4x4 are obviously not capable of. 242 is pushing it for an 8x4 on an uncongested node.

    There are some 16x4 modems available for $55-$60, which is probably fine for Performance Pro as long as you're not on a really congested node, but 16x4 can only handle up to a 400mbps tier, and barely at that, so another promo package and speed bump later, that will be obsolete too.

    A DOCSIS 3.1 modem is as "future-proof" as you can get, but of course you could get N+0 and FDX, and then that's obsolete too, so as it goes with technology, you can never truly "future-proof".

    A 24x8 might be your sweet spot, those are around $80-$90. Like I said before, I'd avoid 32x8 modems since they are Puma 6.

    It's the node that matters, not the town. I've been in two different locations on the same system, one with significant congestion issues, one with none. The apartment complex had congestion, the neighborhood of SFUs didn't. I didn't upgrade my modem because at the time, they were running 8x3 on the system, and the other cable company was running 8x2 when I switched to them. I believe both offer gigabit today, I'm not sure if Comcast rebuilt, or if they just reclaimed space with MPEG-4.

    Wow, that was remarkably hard to find.

    So looking at the PDF of my bill.. it's called "Performance Pro Internet" which is basically the same as what I said before.. but on the right side I see "Internet: Download as fast as 150 Mbps"

    So again, it seems to me like you're saying that I really DON'T need a new modem, and the Motorola I have is just fine, and I wouldn't even notice a difference with a new one?

    That's literally the opposite of what I said above, and also just mathematically wrong. You would have 181.5 provisioned if you had the correct modem. I don't know what they provisioned you at, what are you getting on Speedtest.net? If they actually allowed you to get 181.5 off of a 4x4 modem, you'd literally be uncapped for that modem, since it's theoretical maximum is 160 and probably pulling somewhere in the range of 100-140, but sucking down more than half the capacity of the channels you are locked onto is not really how DOCSIS is supposed to work. My parents have a TM822G, which is an 8x4 on Blast! 250, which is provisioned at 302.5, and it can't pull over 290mbps on the very, very best day, so absolute best case scenario for the SB6120 is probably around 145mbps.

    So the question isn't if you would notice a difference, as you absolutely would see higher Speedtest results. The question is what are you getting now, how congested is your node and do you care? That modem is getting really, really long in the tooth. I would have had my parents upgrade way sooner from an 8x4, except that it's their eMTA, and there wasn't a DOCSIS 3.1 eMTA out until the last month or so.

    Correct, it is the node but even the locations in our town where we have apartments they are just not that dense (did I mention small town. :)) None of my friends and family who are spread across town are seeing any congestion issues here or even in the next small town or 20,000 which feeds off the same headend (my dad was the head field engineer here back when it was Adelphia and did the redesign when they switched to fiber nodes and we were one of the first to have the 1-way cable modems with dialup for the uplink).

    Some regions use different names for tiers, and some tiers aren't offered in all regions. IOW "Performance" in one region may not be the same speeds as "performance" in another.

    I used to work phone support for them, but no longer have the relevant material.

    I try to keep the components separate.

    Separate modem, router, Moca 2.0/Tivo Bridge if necessary

    Personally arris sb8200 docsyis 3.1 modem
    Asus Rt-AC5300 Router with merlin & fq_codel qos optimized to negate blufferboat

    Tg862/g voip, modem router emta combo with backup battery for phone service. Note that you can use separate devices for phone & cable internet connections. Also note that I wouldn’t have purchased something this expensive just for phone connection if there where more options. Well, there are more options...they just don’t advertise it.

    Comcast doesn’t like to advertise it, but I’ve gotten them to activate old used docsis 2.0 Emta voip gateways alongside more recent cable modems

    I’ve had one of the aris modems with the PUMA problems. Definitely skip the 6190....go 8200, 6183, or 6140...all are rock solid & the 8200 can easily give you 1gb down with 32 downstream channels & 4+ up channels in real life use.

    A roamio Pro 3tb (built in stream & MoCa adaptor)
    Tivo Bridge (MoCa 2.0 bridge) $40 on eBay.

    MoCa signal levels can be tricky—especially with a house that has hidden splitters hidden in the walls instead of one wire from outlet to a central splitter.

    I was topping out around 160-190mb max until I put put 75 ohm termination caps on all unused coax outs & put MoCa filters at the splitter to block MoCa from going down legs where it isn’t used in addition to using it as a POE filter. The MoCa filters & the termination caps reflect the MoCa signal & give me better signal levels & thuroughput.

    As far as upgrading from MoCa 1.1-2.0/2.5.
    Pointless unless you are using it as a wired backbone for your access points,

    I have a Roamio that maxes at MoCa 1.1 & 5 Tivo Mini (9300) boxes
    The boxes all claim to be capable of around 280-290mb/s over MoCa 1.1. Minus Streams don’t use as much data as you might think with the hardware decoding chips. MoCa 1.1 is good for 6 simultaneous screens (Roamio & 5 mini) plus an Actiontech MoCA 1.1 AP all off the Roamio’s MoCa bridge, MoCa 2.0 sounds nice, but it doesn’t make sense to upgrade just yet... probably not until 4k broadcasts are regular

    Don’t see any point in paying for a 4k setup when cable is only 720p
    Or 1080i for locals.

    Im waiting for something after the minivox....For $180, I would get an Apple TV or something else. All it provides is streaming 4k apps, but most every 4k tv already has those built in. The mini 9300 have rf remotes natively...so you don’t need dongles for rf, vox, slide remotes like you would with the 9200 mini. The 9300# go for about $100.
