Reddit reviews ZOOM TELEPHONICS DOCSIS 3.0 5341-00-00J 343Mbps Cable Modem

Docsis 3 modems aren't too expensive. You can buy one yourself for cheap and still get better internet speeds.

If you're in the US

• Buy a cable service package from whichever monopoly controls your region. Just search "cable service provider [city]"
  
• Buy a modem. This turns your cable into internet
  
• Buy a wireless router. This turns your hardline internet into wireless internet.
  
• Hook up all that stuff.
  
  You can rent these things from the major providers but after 10 months buying your own equipment will pay for itself and you can take it with you. The modem and router I listed are the ones I have in my apartment and I highly recommend. Good speeds and connectivity all over the entire place. It'll run you about $130. Definitely worth it. I've had mine for almost two years with no issues.

not sure where this goes, as i'm new to this as stated before..

But the ZOOM 5341J http://www.amazon.com/Zoom-DOCSIS-Cable-Modem-5341J/dp/B0063K4NN6 is the only modem I've used for TWC that provides seemingly uninterrupted service in the last 6 months. Hopefully this works for the other unlucky TWC Guardians out there as well.

Get a zoom, not this, surfboards have been hated for a few years now.

Mediacom internet is just fine for me. Be sure to negotiate down your price. I was able to get a $45/mo for 1 year, $54 for second year with a 2-year contract for 15mbps speed.
Also, buy a modem so you don't have to pay $5/mo to rent theirs.
I've been with Mediacom for about 8 or 9 years...I used to despise them, but to be completely honest, I can actually tell they are trying to make strides with their customer service. I have gotten follow-up phone calls to make sure the issues I had were resolved, which has never happened in the past. It's the best ISP I can get for my needs - I sincerely have no problem with them.

I decided to buy a Zoom 5341J modem. I'm tired of renting the POS that they gave me.

Here is a link for supported modems. Good luck!

Not the slightest difference for me yet. Using this DOCSIS 3.0 modem but not sure what I'm missing: http://www.amazon.com/Zoom-DOCSIS-Cable-Modem-5341J/dp/B0063K4NN6/ref=cm_cd_ql_qh_dp_t

Guess I'll try again tonight/tomorrow. Glad to hear most others are seeing improvements!

I've had good experience with Comcast's pricing, but I have heard of it being pretty silly in some places.

The price doesn't include the cost of the gear rental, which adds at least another $10 to the price. Thankfully you can buy a modem/router for pretty cheap. If there is only one computer, you can use a simple one or four-port modem and they cost about $50. I have this one, but I guess it isn't being made anymore. There are similar ones on Amazon for the price I paid for this one.

Also depending on where you live, there might be a state level aid program for Internet access.

I would highly recommend staying away from them. They are honestly extremely unreliable and notoriously crappy. With that said, you can get separate boxes for around that price point.

$60 router (preloaded with dd-wrt): http://www.newegg.com/Product/Product.aspx?Item=N82E16833162069

Or if you don't need 3.0, you can get:

$40 docsis 2.0 modem: http://smile.amazon.com/ARRIS-Motorola-SURFboard-SB5101U-DOCSIS/dp/B002M3SHXA

For the modems, make sure they are on the compatibility list for your ISP before buying. While ones not on their list will sometimes work... Sometimes they won't and your ISP will respond to any troubleshooting with "you need to buy a supported modem"

you really shouldnt go cheaper than this:

http://www.amazon.com/Zoom-DOCSIS-Cable-Modem-5341J/dp/B0063K4NN6/

you want to get a DOCSIS 3.0 modem, and its going to be tough to find one for $50. you might find some arris or motorola modems for a bit less on amazon, but if you buy an arris/motorola from amazon and its not a white model, it wont have a warranty. this is because arris/motorola does not sell to the public, they have to be purchased from the ISP. except for the white motorola models.

It's always cheaper in the long run to buy your own than to rent a modem.

Speeds, no.

I have a Zoom and it's great. http://www.amazon.com/gp/aw/d/B0063K4NN6/ref=redir_mdp_mobile

Just be sure to get an 8x4 not a 4x4 modem. I linked to an 8x4.

Going to depend on your budget. Personally I am a big fan of the Zoom 5341J cable modem - it gets overlooked often by the Motorola SB6141, but it has a ton of positive reviews and I have had one running with no downtime (except for power outages) for something like 3 years. I bought mine at Office Depot but Amazon has them too for $58.99.

Given that your connection is only 25mbps, you have a ton of reasonable options for the router. You could really spend as much or as little as you want. The TP-Link Archer series (C5, C7, and C9) are popular on here and start at $75 on Amazon. There are a boatload of cheaper routers that may or may not get the job done. If you're not covering a huge area, don't have a ton of devices, and don't need gigabit LAN, you could get by with something like the Asus RT-N12. In short, router suggestion will depend on budget and use case.

Any of the above will be much better than the Comcast-supplied combo.

Had a SB6141 at first, however there have been some really strange issues with that modem (take a look at: http://www.dslreports.com/forum/r29437035-Speed-Speed-Issues-with-SB1641) that affected mine as well. I would only get max about 1Mb/sec down with it.

I swapped it for a Zoom 5341J , and it has been rock solid for me. Native IPv6 works fine through it, and I max out my connection.

Saying DOCSIS 3.0 supports 1Gbps will probably end up being misleading to most people. Practically, it depends largely on other issues; primary among them the number bonded upstream and downstream channels.

DOCSIS 3 modems which support more than 8x4 (down/up) are only just now being released.

If you have something like:

http://www.amazon.com/Zoom-DOCSIS-Cable-Modem-5341J/dp/B0063K4NN6/ref=sr_1_1?ie=UTF8&qid=1418777025&sr=8-1&keywords=zoom+docsis+3.0

you'll be fine on the extreme tier here (quoted 150Mbps/20Mbps)

However, if we are lucky enough to get a ~300Mbps tier, you'll only be good-ish. I say good-ish, because at that point you'll want a 16x4:

http://www.amazon.com/ARRIS-Motorola-SurfBoard-SB6183-DOCSIS/dp/B00MA5U1FW/ref=sr_1_1?ie=UTF8&qid=1418777243&sr=8-1&keywords=SB6183

I would recommend staying away from any of the modem/router combos. Mainly if one of the components goes bad you'll need to replace the whole thing.

I'm going on the assumption that you do not have the Comcast Voice (telephone) service, you can't go wrong with the SURFboard SB6183, SURFboard SB6190, or if you want to go cheap the Zoom 5341J is a good modem.

As for WiFi.. depends on your needs.. how many users, how big your house is, how much coverage is needed.. You can get something relatively low cost such as the TP-LINK TL-WDR3500 or you can spend a ton of cash on something like this monster ASUS RT-AC5300.

Zoom 5341J http://www.amazon.com/Zoom-DOCSIS-Cable-Modem-5341J/dp/B0063K4NN6

Asus RT-N66U http://www.amazon.com/RT-N66U-Dual-Band-Wireless-N900-Gigabit-Router/dp/B006QB1RPY/ref=sr_1_4?s=electronics&ie=UTF8&qid=1412717175&sr=1-4&keywords=rt-ac68u

If you have a use for AC wireless, you can upgrade that Asus to the RT-AC68U or similar. I've had the Zoom modem on an APC for over a year, no reboots, no resets required. A very solid modem.

Don't rent. Buy one. It'll easily pay for itself over a few months. There are different cables modems as well, the more common ones are 8x4 (8 downstream and 4 upstream). The newer ones are 16x4, which work with TWC's 200+ Mbps speeds. There are even crazier modems that just recently came out that can do 24x8, which supports nearly 1 Gbps.

I went with the Zoom 5341J. No problems in the past 7 months (and it paid for itself!) as well as consistently seeing 175+ MB/s even though I'm on the 150MB/s plan.

I prefer this one

I use a Zoom docsis 3.0 modem that was about 60 bucks on Amazon at the time I bought it. I believe it is this one and I can double check when I get home. It's probably not the cheapest out there but I read it had the least problems with Comcast of the ones I looked at. I know the Motorola surfboard modem is also popular and is the same price or cheaper on eBay (I think through newegg).

Others have suggested that you purchase a different modem to use in place of the Xfinity gateway, and then using your own router to handle uPnP since the comcast equipment is rife with problems. This is really the best solution. You can grab a list of Comcast compatible devices from their device info page. To my amazement, that page also includes links to buy the devices on Amazon.

If you do purchase your own device you can return the comcast gateway and save 7 bucks a month. I use the Zoom 5341J and it paid for itself in 9 months.

Put a decent router behind it and you'll have a much better experience than trying to make devices play nicely with the comcast equipment.

There is also another option: If you have a different router now and don't want to purchase your own modem (bearing in mind that your own modem will be cheaper in the long run), you can call comcast and ask them to put the xfinity gateway in bridge modem, which will make it act like a cable modem and stop trying to route packets. At that point you can connect your own router to the modem and configure it however you like.

I'm in Bolingbrook, and have the Blast package.

I use this modem: https://www.amazon.com/gp/product/B0063K4NN6/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

and a separate router.

I've been extremely happy with this setup.

Personally I find the Zoom modem to be about twice as reliable compared to the Comcast provided modem(s) that I've had. It drops it's connection much less often.

Buy your own modem. Check this list for approved devices: http://mydeviceinfo.comcast.net/
I bought this one, works great: http://www.amazon.com/gp/product/B0063K4NN6/ref=wms_ohs_product?ie=UTF8&psc=1
After 8.5 months it's paid for.

I have the Blast package (50mbps) and I regularly pull almost 60mbps.

Shopped modems for a few weeks, and settled on the Zoom 5341J. Read several reviews about stability issues on the surfboard modems, but not with the Zoom modem - so I went with it instead. 8 channel DOCS 3.0 with a gigabit port.

Also, make sure that the power levels of your comcast line are within spec. When the technician first set everything up, I couldn't pull more than 25mbps because the line was at 8 dBmV and a little unstable. The tech said that he has found the most stable connection from -4 dBmV to 4 dBmV, so he cut it down with a splitter and I haven't had a problem pulling over 50mbps since then.

I have a used modem and router available, both in good shape

the modem is on time warners approved modem list or whatever it's called

$80 takes em both

NEVER get an all in one modem/router/wireless combo. They are cheap, shitty pieces of hardware.

Wirecutter just had a good article on wireless routers. They suggested the Archer C7 for a solid fast wireless router at a solid price.

If you go mediacom the Zoom 5341 is a good modem that beats out the Motorola Surfoard 6121 at the same price point. I actually have both because Mediacom tried to tell me it was my modem that was the problem.

I currently have Mediacom and paying less than $50 for 100/10. Just agreed to a 2 year and will got up by $10 in the 2nd year. In my first 2 years I had a total of about 2 weeks worth of problems. The longest being 5 days without internet. They do pro-rate for down time and I actually got about 5 weeks comped because the issues were ongoing. The best way to get fast service is to complain at their twitter account. Getting a good tech is a crapshoot. I've had both good and bad. I have a bit of networking background and when I know more than they do I almost always have to call again. When you do get a good tech shit gets fixed.

Excellent router choice. I love the hell out of my ASUS router. If that Motorola modem starts acting up (like mine did) I'd highly recommend getting the Zoom 5341J instead.

Comcast's piece of shit modem/router that they insist on providing is a joke. I sent it back and bought my own modem while using my existing router.
Works great, and I save like $8/month.

I use this one with comcast, and I love it

The Zoom 5341J offers the same # of bonded channels, has a better chipset and cost $69.

Don't have one for sale, but highly recommend the Zoom 5341J. I had this the past 3 years when I was with Comcast and it was a solid modem. I never had to restart it for any issue. If service went down, it would automatically restart when service was back. If I ever go to back to Comcast again, this will be my modem of choice.

I think there was a thread a month or two back with the same question, you can pbb see more answers there.

I've been using the Zoom 5341J for 3 years and so far it has been able to keep up with Comcast's speed increases in my area. I'm on "Blast" tier and get about 180 down 10 up. They're well reviewed and cheap on Amazon:

http://www.amazon.com/Zoom-DOCSIS-Cable-Modem-5341J/dp/B0063K4NN6

You could also put your Netgear in bridge mode (modem only) and hold off until DOCSIS 3.1 hardware and service starts rolling out.

> What's the conversion rate from MBPS to ZOOM

https://www.amazon.com/Zoom-DOCSIS-Cable-Modem-Model/dp/B0063K4NN6

I use my own modem and never have ever had an issue. The reason why they suggest their modem is so they can charge you $10/month to rent their equipment.

I'm paying for 150Mbps and I'm consistently getting over ~190Mbps

This is the modem I have, in less than a year it'll pay for itself since you won't be paying $10month to rent their shitty ass gear.

https://www.amazon.com/Zoom-DOCSIS-Cable-Modem-Model/dp/B0063K4NN6

Any Docsis 3.0 Zoom modem will be perfect. They are tiny and do their job very well.

If so, the specs look pretty good. Hopefully its not a faulty unit. Didn't even think about it being an outside line. Hopefully its just a bit of corrosion / improper seal on the line coming into the house then.

Motorola modems are overpriced IMO. I cant recommend them. The one listed below is only capable of 4 downstream channels. Thats not good in 2016.

Id get this Zoom modem that is 8x4:

https://www.amazon.com/Zoom-DOCSIS-Certified-Comcast-XFINITY/dp/B0063K4NN6/

There is also a newer model from Zoom that offers 16 downstreams for $80.

I would recommend a Netgear N300 for your router. But if you want a all in one unit Zoom offer that modem I linked you combined with a N300 router:
