Review: Out of the box inspection, installation, and testing. Comcast Houston. Love it. - This review is an "Out of the box installation, and testing" type review. I have had the modem in my possession for less than 24 hours, so I honestly can't say much about stability or long term reliability yet. I do intend on updating my review as I have more exposure to this device. After getting annoyed one too many times for paying a $7.00 / month lease fee to Comcast for the AMBIT U10C035 DOCSIS 3.0 modem that replaced the older Motorola Surfboard modem I had when the cable service in my area used to be Time Warner / Roadrunner. Well I decided to buy my own modem and bypass the middle man. After doing some thorough research of online reviews, I had the choices narrowed down to this modem, the Motorola SB6120, and the Motorola SB6121. Several factors, including the overwhelming positive reviews of this modem here, and on DSLreports.com, not to mention the recommendation of several Comcast cable technicians made me opt in favor of the Zoom modem. Now the last time I had purchased, or even considered Zoom equipment, it was a 33.6 kbps internal PCI modem I had installed in a Pentium 166 MMX box running Windows 95. Not exactly current. My experience with their hardware was positive, and I have never had a reason to doubt the quality of the design, or build of their devices. Just didn't have a need until now. First thing I noted when it came in is how well the item is packaged. Decent cardboard box that protect's its contents. baffling inside the box designed to hold the contents snug. The modem itself well wrapped, and the box as well fully plastic wrapped. Maybe not the best for allowing the plastics to outgas, but I digress... Included in the box was. #1. Zoom 5341j cable modem. #2. Wall wart type transformer. #3. Short, BRIGHT yellow ethernet cable. #4. Funny looking little foot thing a ma jig used as a stand. Mine will be shelf mounted eventually in a relay rack in my home office, the little foot isn't needed, but would be nice if I didn't have my setup planned the way I do. #5. Quick installation guide type pamphlet. Physically there are a couple of noteworthy things about this modem. #1. Matte black finish of the housing fits in very nicely with modern office and particularly home office decor. #2. Multiple, flexible mounting options. The only real mounting option this lacks, and it is one for my application annoys the snot out of me, is it lacks any means of attaching rack mount ears. So if you are doing a structured wiring install, using a relay rack or similar setup, you will have to use a shelf on the rack for your modem. For the most part, almost all current broadband modems and routers are like this. I guess the MFGs don't figure home or SOHO installs will use racks. #3. Much, MUCH brighter status LEDs than the Ambit, or Moto modems I have had in the past. There is no guessing to the status of a particular function of the modem in a bright office. I bet the lights could be annoying in a bedroom at night though. #4. Smaller footprint than the Ambit or Moto modems. Agan, for the most part no big deal, but again, for those doing structured wiring, say you are doing a mount board install in a closet, or basement. Or worse, an actual structured wiring enclosure. The smaller device is priceless in space confined areas. #5. Although I didn't measure scientifically, the Zoom produces significantly less heat than the Ambit did. For the most part, the Zoom seems to be running just a touch over room temp, the Ambit always gave me pause as it ran hot enough ti was concerned it would melt the plastic or worse. #6. Unless you have everything at the same desk area, forget the included ethernet cable. Too short to be useful. #7. The little foot thingy installs and removes fairly easily from the modem allowing you to stand it up like a book on a booshelf. Nice option if you need that. #8. The wall wart transformer. You'd think by now, manufacturers could figure out how to integrate the power supply INTO the housing of the modem. I hate external transformers. This one at least is one of the sideways ones so you can actually use it in a power strip, at least that's something. Setup was quick and relatively painless. #1. Get online, go to Comcast website, log in, then copy / paste my account number to a plain text file. #2. disconnect my existing cable modem. #3. Connect coax, power cable, and an ethernet cable from the wired workstation to the new cable modem. #4. Power the cable modem up and wait for all the lights except the last one on the right to stop blinking. The last one on the right if it blinks means data is getting passed... #5. Set my workstation to DHCP for adddress and DNS configuration. You can bypass this step if you are using DHCP, I am not. #6. Flush old IP, and obtain new ip address. (For Windows XP run ... ipconfig /release, ipconfig /renew). #7. Open web browser nd try to surf to a site. You will get taken to the self activation page. #8. Follow the simple to understand on screen prompts. #9. Once it shows up as activated, and confirms you are done, it will prompt you to close the window. Do so now. #10. Browse to a site or two, pull up desertcart.com, google.com, whatever verify your function. #11. Push the button on the back of the modem and power it off. (How cool is that, an actual way to power cycle the modem without yanking the power cord!) #12. Connect ethernet cable from router to modem. Reconnect worksation cable from router to workstation. #13. Powe roff your router. #14. Power on your modem. Wait for it to fully initialize. #15. Power on your router. Wait for it to fully initialize. #16. Obtain new DHCP address by release / renew mentioned above, or reset your static IP addressing. #17. Log in to your router admin panel, and verify IP configuration is good. #18. From your worksation / browser, start browsing the internet. All told, my setup took all of 15 minutes. The overwhelming majority of that time was spent waiting on the Comcast website to do its thing. Prior to, and just after installing my modem, I ran several broadband speed tests to verify function. First testing was done at [...] My test prior to swapping the modem out came in with 24.86 mbps down 3.28 mbps up. My test after swapping the modem out resulted in 33.18 mbps down, and 3.74 mbps up. The results from testmy.net are similar. Prior to swapping the modem out I got 20 mbps down, and 1.8 mbps up. Post modem swap I am getting 24.9 mbps down, and 3.6 mbps up. I should also mention that I bumped my service tier up after the post modem test (I had intended to do that, and was part of the reason I got this modem). I am now on the Extreme 50/10 tier. My speed scaled right along with the tier inline with what I was seeing before. Download of 67.85mpbs, up of 9.89mbps. At the time of this test, for some reason I was unable succesfully run a speed test from [...] The Flash test app on their site kept hanging my browser something fierce. Overall browsing seems snappier, but it's not like it was a problem before. For the most part, I am limited to the speed of the connection the servers I am talking to, which makes me a happy camper. Youtube can still be choppy, but I have seen that across various networks, and the problem is Youtube. Netflix is smooth as silk, and a joy to watch. I am not much of a gamer, other than Facebook games. And those, well they don't appear to have been impacted at all. At this point, assuming no stability or reliability issues, there are 3 things I would like to see Zoom change about this device to make it more appealing to me. #1. Wrap the lenses for the LEDs around further to the front. This will make viewing the LEDs from just below the modem much easier. #2. Integrate the power supply into the modem housing. #3. Slightly modify the case design to allow for, and include, or offer as an accessory, rack mounting ears for the device. I know I am the odd man out here as it were, but it would be nice.. UPDATE: 3/31/17. I have owned this modem for 4 years and pretty close to 2 months. We are going to call it 50 months. I am saving $8.00 a month plus So effectively this modem has saved me after purchase price close to $440.00, and I can manage my own modem without Comcast sticking their nose into it. It's been wonderfully reliable, and a great performer. I am tempted by the newer 4x16 DOCSIS 3.0 modems, but our service here won't support them anyway. Might as well stick with the 4x8. I should mention my first modem, a dial up 2400 baud modem in the 1980s was a Zoom, my 33.6, and 56K modems were Zoom, I am glad beyond words that Zoom has kept their quality high over the literally decades. I deal with IT all day long and have seen a lot of junk networking gear on the market. This is a good modem.
Review: Excellent cable modem from a great supplier - My DSL supplier recently increased my monthly price, after 12 years of reliable but never upgraded service, by nearly 15%. I took that as an opportunity to check out cable ISP and found I could get an intro price that not only allowed me to purchase a cable modem but save me total $$ outlay for more than three years - AND enjoy 10x increase over the d/l speed I had. I looked at various mfg offering cable modems, but couldn't find anything that I really wanted/had good ratings. Finally, a no-brainer kicked in... "Look to see who manufactured the DSL modem you've been using 24/7 for that past 12 years with complete satisfaction, dummy." Dah! It was a Zoom. The Zoom 5341J has all the features I want & need, is from a reliable mfg, approved by the cable company I was signing up with, and at a reasonable price. It works with my Netgear Router with no issues. Two negatives: The first modem I had was faulty and had to be returned, but crap happens. The other thing is that it (both) runs a little warmer than I'd like to see. However, after three weeks usage I am completely satisfied and would recommend this to anyone wanting to stop paying monthly modem rental to their cable company or looking for a new modem for any reason. Update: I've been using this modem for four months now, it is on 24/7, and I have had zero issues. I had a general question about the light activity on the modem and sent an email to Zoom. This was not a problem -- just curiosity. My question was answered and explained to me quickly and clearly. I am completely happy with my purchase.

### ⭐⭐⭐⭐⭐ Better than Motorola SB6121 & SB6141 *In my experience*
*by D***T on June 29, 2014*

I'm writing this review as the Motorola SB6141 sits on my kitchen counter with the return shipping label, waiting to be dropped off at UPS. I will try and make this a lot shorter since I'm coming back to edit my last review in which I gave the product 4 stars and titled it "The jury is still out..." Well the jury is in with its verdict. Keep in mind, I'm no internet tech, and my experience is based solely on how the Zoom 5341J performed compared to the Motorola SB6121 and SB6141, *with my specific service provider (Comcast), in my area, and in my home*. All of these factors can have a significant effect on your own experience. Here is a rundown on my experience with each of the aforesaid mentioned devices. If you only want my comments on the Zoom 5341J just scroll down to it. All devices were used in conjunction with Comcast Performance Blast service with 50 mbps download, and 10 mbps upload bandwidth speed. I measured the speed using speedtest.net. Each of the test results were reported to me using a server based in my city, so all of the results are best case scenario. Motorola SB6121 To this day, I am still convinced I either bought a defective device, or Comcast did not recognize this device from the jump properly. From the moment I activated this modem, my bandwidth speed would jump from 58 mbps down and spike wildly all the way down to about 2 mbps, the upload speed would never eclipse 3 mbps, and usually hovered around 0.9 mbps. I tried restoring the factory settings online. The only result was the modem updated to a newer firmware, but that did not solve any of the bandwidth speed issues. The pings were very high as well about 70-160 ms, which is way too high for a test using a server in my own city. I also deactivated and reactivated the modem multiple times in hopes that whatever the issue was would resolve itself. I would get the same results over and over. I also tried a slew of fixes that I researched online. Nothing worked and internet was basically unusable. Motorola SB6141 This device worked much much better than its predecessor, it just didn't perform as well as I felt it should have. Hardwired to the modem the SB6141 would get me 58 mbps downstream / 14 mbps upstream, which was beautiful to behold. In my bedroom (where the device was set up) over wifi, I would get a steady 55 mbps downstream and 14 mpbs upstream. I was living the dream for a few days. About 2 or 3 days later the Netflix streaming out in my living room would start buffering, and this is something that never happened with my previous DOCSIS 2.0 modem (Motorola SB5101), so I started doing speedtests again HARDWIRED to the SB6141. This time, although I was still getting relatively good speeds, the mbps would jitter up and down. Sometimes one test would start at 58 mbps and end at 35 mpbs downstream. Others would start at 30 mpbs and go up and down and end at 45 mpbs. Like the internet was struggling to get through at a steady rate. Pings would range between 14-40 ms. Not the vision of consistency I envisioned. Again, I know these results can depend on a lot of things besides the modem, but I've come to the conclusion it was the modem based on how the Zoom has been performing. I did the same things I did to the SB6121 to try and remedy the SB6141. Sometimes the speeds would be great, sometimes they would be ok, and sometimes they would jitter, all within a few minutes of each other. I kept a hold of the SB6141 to see if the Zoom (which I actually purchased before this device) would suffer the same issues. Zoom5341J From the moment I activated, to right this minute as I write this review, this device has worked flawlessly. I actually bought this device after the SB6121 failed me, and because I did not trust the brand name Zoom as much as I did Motorola, and the device seemed to run a little warm, I went and got the SB6141 just to make sure I was getting a quality product. My experience with the SB6121 should have taught me Motorola wasn't going to work for me in my situation, but I wanted the certainty of the name. Through primetime internet using hours, over wifi, hardwired, using multiple internet devices simultaneously, this thing has been an absolute beast for me. It gets me 58 mbps downstream 14 upstream hardwired, over wifi in the same room it gets me 55 mpbs downstream 13 upstream, out in my living room over wifi it gets me 21-30 mbps down/ 11 mpbs up. Although the distance from my bedroom (where I set up my modem/wifi) to my living room is not very far (roughly 75 ft), there are 2 walls, an AC unit, a water heater, and a patio between them. I know a lot depends on the wifi router, but the 5341J has been making sweet sweet love with my Netgear N300 WNR2000v3 (which is very far from a great router nowadays). The most impressive thing thus far is that I haven't had to do any research to get it to act right, my internet speeds have been steady as a tank, and it has not disconnected one time throughout the period I've been using it (roughly 2 weeks). If Zoom keeps this up, I may have to start purchasing more devices from them. Sidenotes: The Zoom 5341J runs warmer than both of the Motorolas I purchased. I wouldn't call it hot, just warmer than other modems I've had. If anything happens with the modem, I will be back here to report it. Also, the LEDs on the 5341J are BRIGHT. They can light up a corner of a dark room. At night it serves as a nightlight to keep monsters away and if I have to get up and use the bathroom haha. Its not "burn your retinas bright," its just "3 x brighter than the SB6141/6121 bright." Its not a problem for me, just something maybe others would want to know about.
