supports docsis 3.1

you're always better off with your own modem than the cable company's modem.

u/chronop · 4 pointsr/techsupport

It depends on your ISP, Gigabit is possible with DOCSIS 3.0 by bonding extra channels but not every ISP supports that configuration. You would be much better off with a DOCSIS 3.1 modem, especially if your ISP is telling you that it won't work. More importantly, the SB6190 uses a faulty Intel Puma 6 chipset which will cause issues no matter what service you use. Here is my source for that claim. A good modem to use for Gigabit service would be an SB8200 or a CM1000, they both use a Broadcom chip rather than the faulty Puma 6.

u/nvertedflyer · 3 pointsr/homelab

Hell, PM me your address, you can have mine. I just upgraded to business class and don't need it any longer. Worked great with Xfinity here in Tennessee.

Edit: pretty sure it's this one, but too lazy to go look right this second.

u/DZCreeper · 3 pointsr/HomeNetworking

DOCSIS 3.1 is basically a big revision of 3.0 that improves channel configuration, modulation, and encoding. Bottom line is more throughput for you and flexibility for your ISP.

The downside is pricing. You will be paying at least $160 for the modem, with the recommended unit being the Arris SB8200 for $190.

https://www.amazon.com/Next-Generation-ARRIS-SURFboard-SB8200-DOCSIS/dp/B01N6SKK1G

As for the router, at minimum get an EdgeRouter X. Another popular option for people with gigabit connections is a pfSense box.

For wireless connectivity a Unifi AC Pro access point is the fastest option if you don't want to spend an unreasonable amount of money. If you are fine with 1 less spatial stream then a pair of the AC Lite access points is only about $20 more and gives you a lot more coverage.

u/AceBlade258 · 3 pointsr/homelab

There are a few modems avaliable that are both Comcast compatible, and have gigabit throughput. Alternatively, you need to put that thing in bridge mode: just call their tech support and it will take a couple minutes tops.

u/fredphreak · 3 pointsr/HomeNetworking

If you're looking to upgrade sooner rather than later, look for a DOCSIS 3.1 modem. The SB6183 tops out at 686mbps, according to the manual. I've got 400 down at home, so I haven't had a chance to max it out. Something like the Arris SURFboard SB8200 would work for 1Gb.

u/9sW9SZ189uXySHfzFVFt · 3 pointsr/cordcutters

You can buy your own modem but you'll need to get one that is docsis 3.1 compatible like this.

u/SemperFlux · 2 pointsr/linux

Ha, that's totally fair!

I thought at first I could get away with buying The SB6190 (https://www.amazon.com/gp/product/B016PE1X5K), because it said it was valid for 1.4Gbps downstream, but I could barely get 250 down out of it. I really don't understand where that claim comes from or why it's full of shit, but I really didn't care to figure it out.

I looked at Comcast's site and they actually recommended the SB8200. It was pricey, but it fit the bill and works great. I bought it from Amazon: https://www.amazon.com/Next-Generation-ARRIS-SURFboard-SB8200-DOCSIS/dp/B01N6SKK1G/

I bought mine for $210, but now, it looks like with the $20 coupon on the listing, you could get it for as little as $169, quite the deal.

What was nice for me was because I was moving up from an older Comcast registered modem, all I had to do was plugin the modem, plug my laptop directly into the modem, sign into my Comcast account, and boom, it took care of registering everything for me. I didn't have to manually register the MAC on the modem.

It was surprisingly and suspiciously easy for a standard Comcast service experience, so might not be as smooth for you.

u/z3dster · 2 pointsr/washingtondc

Kable Towns CS is okay if you know how to work the system, they are working on unifying in one large call center in AZ to improve. X1 is pretty good, just avoid any of the non XG2, XG1, or Xi4 boxes if they are still out there (I'm looking at you rng150n)

Only issue with any cable company is if they oversubscribe their lines, which comcast often does. This means as more people use the node you are on you get drop in speeds (5-10pm)

Verizon: Depending on where you live you can do VZ Fios for internet and Layer 3 for TV on top of it, if you don't need live sports Hulu/Netflix/HBO Go are better options then any tv service

DirectTV Agree with above

Note on Modems: The current modem standard is Docsis 3.0 but 3.1 will roll out in the next few years. Right now Docsis 3.1 modems are 2x the price of a 3.0 modem, get the 3.1 as it is more future proof and will save money in the long run

Renting modem? $8 a month

Buying a docsis 3.0 now ~$80 + a 3.1 later ~$80-$100

Buying a docsis 3.1 now $190 https://www.amazon.com/dp/B01N6SKK1G

The surfboards will always be on the approved list and when 3.1 launches in your market you will get the speed bump instantly

Looks like Comcast will launch their 3.1 offering in DC in the near term, hello gigabit over copper

u/lilotimz · 2 pointsr/HomeNetworking

For comcast gigabit you'll be needing a DOCSIS 3.1 capable modem such as the Arris SB8200.

For a router, for all in ones you can look at the typical Netgear R7000 or the Asus AC1900 if you want to keep it simple.

If you want something super reliable then...

Edgerouter X

or

Edgerouter Lite

or

Unifi Security Gateway

u/geekywarrior · 2 pointsr/cordcutters

I'm not sure what your budget for this equipment is as DOCSIS 3.1 equipment seems a bit pricey at the moment.

But I've used the older Docsis 3.0 version of this modem since 2014 with COX. I've had to reboot it all of maybe 4 times over the years. Mine was Motorola Branded but it looks like the exact same modem with a new label and updated hardware.

https://www.amazon.com/dp/B01N6SKK1G/

I recently installed one of the higher Netgear nighthawk routers in a small business that wanted to expand their wi-fi in the building. I can't find the exact model I installed but I'm fairly certain it was this router. This thing was nuts, the 2.4 GHz band punched through 3 floors and went way out to their parking lot. 5GHz band didn't go quite as far (as expected) but was crazy fast when I was in a reasonable distance to it.

https://www.amazon.com/dp/B0192911RA

Self installation of this equipment is super easy.

  1. Unplug the Coax from your existing modem.
  2. Plug in the Coax to your new modem and connect a laptop or desktop pc to the ethernet port with a short cable.
  3. Call Cox support and tell them you want to activate your own modem. Read them the MAC address and any other information off of the new modem, it is located on a sticker on the modem itself as well as may be on some paperwork that comes in the box.
  4. They'll activate it and then ask you to confirm internet works on your attached computer.
  5. Once that is all set you can hang up with them, unplug your laptop and plug that ethernet cable into the yellow port on the router.
  6. Then it looks like Netgear has some handy app to set these things up, I usually do it myself in the web config but the app will work fine even if you've never set up a router before.
  7. Once you are done, confirm your new wifi works and test the range. Remember that 2.4 reaches farther but is slower. 5 is faster but does not reach as far.
  8. If everything works as expected for a few days or so, find the closest COX store and return your equipment in person, making sure to get a receipt claiming you returned your equipment so you have proof to contest if they keep charging you a rental fee.
u/STODracula · 2 pointsr/Comcast

Stay away from SB6190. If you want future proof then go all the way to DOCSIS 3.1 using the SB8200.
https://www.amazon.com/dp/B01N6SKK1G

u/PythonTech · 2 pointsr/pcmasterrace

Make sure you match the modem to what speed plan you have. If your ISP doesn't offer faster speeds, there is no point in getting a more expensive modem.


Less than 343Mbps - https://www.amazon.com/ARRIS-SURFboard-SB6141-Certified-Packaging/dp/B00AJHDZSI/

u/Serial0 · 2 pointsr/jacksonville

From mydeviceinfo.xfinity.com I see these devices are compatible with 1000 Mbps service:

Arris SB8200

Motorola MB8600

Netgear CM1000

u/NeetSnoh · 2 pointsr/wifi
u/rtechie1 · 2 pointsr/HomeNetworking

> I read on several websites that even though the modem says it can handle up to 343Mbps, it usually tops out at 100.

That's correct. You get speed increases on cable modems by "bonding channels" together. Ultimate 200 requires 16X4 bonding and the SB6141 only supports 8X4.

Get the newer SB8200 instead, supports bonding 32x4 for future speed increases.

As others have said, changing the modem won't affect WiFi speeds and you already have a pretty beefy router. I think the problem is with your client.

u/Bah15362 · 1 pointr/Waco
  1. get your own modem. I use This currently. If you look at others make sure they are docsis 3.1. also make sure it's just a modem. not a modem/router hybrid. The hybrids are a true case of "master of none". you will have to call them and tell them the MAC address so they can provision it.
  2. Get a new router. Not a fan of TP-link. I would aim for a netgear or linksys. make sure to update the firmware when you get it. I wouldn't spend more then 100$ on one. a 1gb port should be able to pull the same no matter how much you spend on it. Focus more on how many devices will actually be running at once than total devices. My house just has my husband and I. at most 2 devices heavily using the network at once. no reason to go to expensive for that level of use. i spent 150 on mine because i use all the extra settings do host servers. most people don't need to do what i do. Mine is actually 5+ years old and is just starting to die now. mostly because the cat sits on it causing it to over heat.
  3. Make sure you are wired. Wireless can only really get to 100 - 150 mbps depending on the distance and any physical blocks.

    different speed tests will show different results. when dealing with high speed lines, sometimes the bottleneck of the test is the test site. Some speed tests are just not designed to test for high speed lines. i have had grande for 3-4 years now and the speeds have been pretty spot on.
u/Chippawah · 1 pointr/HomeNetworking

Literally just went through this! I had the cm700 modem and it would drop connections to Comcast frequently. I went through a couple modem/ router configurations starting with the R7800 and at one point had the Netgear AC3200 router. Having gone through $500+ in networking gear I can recommend the R7800. I’ve got the Netgear R7800 sitting behind the Arris SB8200 and it seems to be a great combo. Handles my roommates and I across the apartment streaming and gaming at the same time. Each of us has a few devices over WiFi and then I’ve got some devices over eth. Dynamic QoS seems good and the UI is decent.

TL;DR: Get the Netgear R7800 and the Arris SB8200

u/freakingwilly · 1 pointr/pcmasterrace

Mediacom requires a DOCSIS 3.1 modem for gigabit services. The only DOCSIS 3.1 modem on the market that is worth purchasing is the Arris SurfBoard SB8200. Amazon currently has a $20 off coupon which will bring the price down to $166, making it cheaper than the Netgear CM1000 (which is actually worse than the SB8200). A better modem for a better price.

As for a router, I strongly recommend the Asus TM-AC1900 flashed with Merlin. The TM-Ac1900 is basically the Asus AC68U with a custom firmware. You can upload your own custom firmware like Merlin, DD-WRT, or Tomato. Merlin offers performance, DD-WRT offers functionality, Tomato offers a little bit of both. I strongly recommend Merlin as it is what I use to hit 900Mbps down with my gigabit service through RCN.

The directions to flash Merlin are super easy if you follow these instructions. It takes at most 30 minutes to do it, from start to finish. When you're done, you will have one of the best routers on the market for a fraction of the price. I have three of these routers (one AC68R and two TM-AC1900, all running Merlin) and I absolutely love them. The AC68R is my primary router which I bought when it first came out, one TM-AC1900 is in my garage as a repeater, and the other is my test/backup router.

If you have any questions on how to flash the firmware, let me know and I'll be happy to help. If you're in or near the Chicagoland area, I'll be more than happy to flash it for you.

u/kevin24lg · 1 pointr/Twitch

For the 1GB speeds, if you're on Comcast you'll need a 3.1 docsys modem which run at like $175, I have this one: https://smile.amazon.com/Next-Generation-ARRIS-SURFboard-SB8200-DOCSIS/dp/B01N6SKK1G/ref=sr_1_5?s=pc&ie=UTF8&qid=1521073314&sr=1-5&keywords=arris. Not sure for other ISP's, but I would check with them.

First thing I would actually check though is your ethernet adapter. On my last motherboard the Realtek ethernet adapter had a lot of "green ethernet" and "power savings" options that were basically throttling me. I would all of a sudden get massive frame drops or my upload would just hit 0 out of no where. Once I killed those I haven't had much issue. Oh also, in OBS under the advanced settings there's a checkbox for "New Network Code". Not sure what it does but that helped too.

Another thing that helps your stream in general is to go to Control Panel -> Power Options and make sure you're on Max Performance. My streams were pretty bad quality on occasion because the "Balance" choice which is default to Windows 10 was basically throttling my PC.

I had a lot of issues with throttling.

You can sorta see it to the left of the QNAP box. I ended up with this one because I have 400/10 internet and needed the download channels. I didn’t need docsis 3.1, but I’ve heard from too many sources that the 3.0 version has issues with the processor or something.

It’s amazing and would recommend it to anyone. It hasn’t failed on me yet.

Not as cheap but I'd rather have reliability of my own modem rather than relying on their eq.

u/Frijid · 1 pointr/buildapc

I have an old Motorola Surfboard. It's about 7-8 years old. I'm going to upgrade it because I've been having unstable internet recently.

Docsis 3.1 is the kind I'm going to get because Cox recommended that I get it because my current modem is 'incompatible'.

Anyway, would either of these be a good pick? I'm waiting for Prime Day:

NETGEAR CM1000

ARRIS SURFboard SB8200

u/blank_dota2 · 1 pointr/HomeNetworking

Really depends on the plan you pick. If you go with gig/1000Mbps, I'd go with this: https://www.amazon.com/Next-Generation-ARRIS-Surfboard-SB8200-DOCSIS/dp/B01N6SKK1G

Keep in mind most of the 32x8 channel modems use the same broadcom chip, so you'll have similar issues across them.

Example this has the same chipset, but a buddy of mine claims it's been more reliable than his SB8200 was: https://www.amazon.com/NETGEAR-Gigabit-download-Compatible-Gig-Speed/dp/B01I5TJGSE

I see some used or refurbished for $140.

u/Emerald_Flame · 1 pointr/buildapc

Okay, for cable internet at those speeds, you're looking at these:

Modems:

SB6190: https://www.amazon.com/dp/B016PE1X5K/

or

SB8200: https://www.amazon.com/dp/B01N6SKK1G/

The 6190 technically supports 1.4Gbps, but the ethernet port on it is only 1Gb which caps you there. The 8200 supports 1.4Gbps and can actually do it because it has 2x 1Gb ports, but it requires your provider to give you multiple IPs for that which is almost unheard of in the consumer space. So effectively both are going to be capped at 1Gb down and 343Mb up.

The 6190 is DOCSIS 3.0 and the 8200 is DOCSIS 3.1. This doesn't really matter right now as everyone supports 3.0 and 3.1 support is just starting, but the 3.1 will be supported much longer. So if you're looking for a modem to keep the next 10+ years, go with the 8200, but if you don't mind saving about 50% now and then buying a new modem in 10 years, the 6190 is great.

Both are on XFinity's supported list.

For routers:

Nighthawk AC2300 R7000P: https://www.amazon.com/dp/B01NA80JML/

or

Nighthawk AC1900 R6900P: https://www.amazon.com/dp/B07C65K9H9/

or

Asus AC66U AC1750: https://www.amazon.com/dp/B01N08LPPP/

The R7000P is a pretty high end pick. It's going to support the fastest wireless speeds on the 5GHz AC band. However, you'll likely be limited by the device at the other end, as most end devices don't support speeds that high.

The R6900P is the next step down. It's very similar, but it's 5GHz AC speeds are slightly slower. Even still though, it's faster than what most devices support so you'll likely be limited by the device.

The AC66U is the more budget pick. It supports the same speeds as the 6900P on the 5GHz AC band, but has slightly slower speeds for older N based devices. For most users this likely won't matter as almost everything is AC these days except for like printers and IoT devices that don't need bandwidth. With the AC66U, you also don't have MU-MIMO support, which the more expensive options do. While MU-MIMO isn't required, it can really help in homes that have lots of devices.

u/le_suck · 1 pointr/Queens

you can now buy your own modem for RCN 1Gb service.

just activated this modem on 330Mb service with no issues in forest hills.

u/Vicing90 · 1 pointr/techsupport

Well, I'm in a similar situation. I basically know what's causing problems but my ISP refuses to solve it and ignores the problem since they'd have to replace some hardware that works but barely.... So I'm in the process of changing. I have a lot of options though, open fiberoptics net that any ISP that wants to can deliver on.

​

I bet your neighbours have coax as well though, not friends with anyone of them and might be able to borrow their modem for a few hours in order to rule out the modem as a problem?

​

When it comes to a new modem, try creating a post in the thread I mentioned and you might want to include what ISP, lots of people there with a ton of knowledge on the subject.

Since you already have a router on the way, you could settle for a coax modem without a routing function. Might be cheaper to return the router and get a 2 in 1 but generally, modem and router is better then a modem/router combo.

This might give you some ideas on what to look for when buying a modem btw: https://www.makeuseof.com/tag/4-things-to-seriously-consider-when-purchasing-a-new-cable-modem/

P.S. You might want to aim for a modem with 16 channels or more (you can view it as a road, more lanes = more traffic can pass trough and it will flow more evenly across the lanes). Check what your ISP supports first though.

Or something along these lines with 32 channels https://www.amazon.com/Next-Generation-ARRIS-Surfboard-SB8200-DOCSIS/dp/B01N6SKK1G

P.S. Very much not an expert at cable modems, just have some limited knowledge on them but the arris surfboard SB8200 looked pretty nice.

u/sivartk · 1 pointr/cordcutters

Motorola Arris Surfboards are good hardware. You'd have to look at the specs of each (as that is what they provide). If you don't want to look at that, just get one that says DOCSIS 3.1 and you will be future proofed.

Whatever you do don't get a modem with a built in router. Your router will (most likely) become obsolete before the modem.

I'm on a Spectrum up to 200Mbps package and I'm using this modem and get 230ish down on a regular basis.

u/taintedbloop · 1 pointr/Comcast

Hey, I was talking with a user in another thread and he mentioned something about a puma 6 chipset which some models use which apparently have problems. They may have partially fixed it with a firmware update but I don't think it's fully fixed. There may be lag issues with that model modem you are getting (SB6190).

If they haven't shipped it yet I would cancel the order. It MAY work okay but honestly I would just return it so you don't have any headache.

It seems like the better choices are the model below it, which I actually just bought used for $34, or the new model with DOCSIS 3.1 which is a bit expensive but is very future proof and about $160 after coupon right now on amazon.

I thought I'd alert you before you set up that modem! It's crazy they're still selling it like hotcakes. Maybe the issue isnt that bad but I personally wouldn't use it. It should be an easy return because its amazon.

edit: If you want a model in between the model below it and the very new model, this $99 Netgear is about the same price and is comparable to the one you bought (though a few less channels) and doesn't have any of the puma 6 problems.

u/evarigan1 · 1 pointr/Rochester

Do you have a DOCSIS 3.1 modem? You'll need that, something like the ARRIS SB8200. You'll notice the statement you posted said Spectrum certification specifically, well the ARRIS has passed other providers testing for certification, and will likely be approved by Spectrum in the near future. The ARRIS Surfboard line is pretty much the go-to for cable modems.

u/dobosininja · 1 pointr/HuntsvilleAlabama

We are on the 500 plan and I got the Arris SB8200 Modem and an Asus AC3100 Router and we have no issues with streaming or gaming. The modem might be overkill but I wanted the ability to go up in speed if needed.
