Vince6 join:2013-01-08 2 edits	Vince6 Member 2013-Jan-8 6:31 pm [TWC] Possible problem with new Zoom 5341j First, I'm sorry if this is the wrong forum to post this. There are just too many to choose from! Feel free to move it if needed. Second, I have Road Runner Turbo (Called Turbo Internet now?) I recently bought a Zoom 5341j to replace my rental Toshiba modem. The speeds with the new modem seemed great at first, but after a few days I realized there is a problem. The speeds are inconsistent and the modem will even totally drop out for a minute or so at a time. I'm checking the speeds at the Time Warner speed test page: »speedtest.twrochester.co ··· test.php I always use the Albany server, since that is closest to me. After a few checks today I got download speeds ranging from 69 to 39 to low twenties. Over the last couple of days the upload speeds almost never finish. They just keep decreasing down to near zero. When they do finish they range from 1.89 to low 1's. I used to always get 1.9x. There is one game I play online where I would get steady pings that varied on server location, but were always steady. Now the ping bounces all over the place durning a game and occasionally hits 999ms for a long enough time that I get kicked from the game. So my question is do I have a bad modem? That would be my first guess since this started when I hooked up the new one. I wanted to check with the experts to make sure though! Here is some info from the modem: Startup Procedure Procedure Status Comment Acquire Downstream Channel 561000000 Hz Locked Connectivity State OK Operational Boot State OK Operational Configuration File OK Security Enabled BPI+ Downstream Bonded Channels Channel Lock Status Modulation Channel ID Frequency Power SNR Correctables Uncorrectables 1 Locked QAM256 4 561000000 Hz -3.7 dBmV 42.0 dBmV 0 0 2 Locked QAM256 1 537000000 Hz -3.8 dBmV 41.4 dBmV 0 0 3 Locked QAM256 2 543000000 Hz -3.8 dBmV 41.9 dBmV 0 0 4 Locked QAM256 3 555000000 Hz -3.7 dBmV 42.0 dBmV 0 0 5 Not Locked Unknown 0 0 Hz 0.0 dBmV 0.0 dBmV 0 0 6 Not Locked Unknown 0 0 Hz 0.0 dBmV 0.0 dBmV 0 0 7 Not Locked Unknown 0 0 Hz 0.0 dBmV 0.0 dBmV 0 0 8 Not Locked Unknown 0 0 Hz 0.0 dBmV 0.0 dBmV 0 0 Total Correctables Total Uncorrectables 0 0 Upstream Bonded Channels Channel Lock Status US Channel Type Channel ID Symbol Rate Frequency Power 1 Locked ATDMA 6 5120 Ksym/sec 23800000 Hz 44.5 dBmV 2 Locked TDMA 5 2560 Ksym/sec 19000000 Hz 45.0 dBmV 3 Not Locked Unknown 0 0 Ksym/sec 0 Hz 0.0 dBmV 4 Not Locked Unknown 0 0 Ksym/sec 0 Hz 0.0 dBmV These were taken right after I reset it. Before I did that the correctables/uncorrectables were all in the four digits. edit: I forgot to mention that I have tried bypassing my router by connecting directly to the modem. I have also tried a different Ethernet cable and have also connected the modem directly to eh feed coming from the pole. This eliminates the possibility of a bad splitter or a bad coax cable in the house. I also had the feed from the pole to the house replace a year or two ago because there was a problem with the tap at the pole and when they repaired it they replaced the whole line because the old one was, well, old and a pretty small gauge.

Radisc359 join:2010-10-02 Fremont, NE 2 edits	Radisc359 Member 2013-Jan-9 12:17 am I get errors similar to those, although my internet speed is great, 30.5Mbps/5Mbps and it works fine until it tries to send a dhcp request(2-4days), it disconnects for like 30 seconds and so far as done so twice. They put my modem under monitor and this one so far beats the SB6141 on my line. I've had some weirdness with SB6141's as well, so I doubt my modem is bad, now yours could be, but I'm not sure TWC even has the right codes for the modem to work correctly in the first place, thus shows those BP+ errors. You have some T3's unlike me, although your signal is good, hmm.

j1349705 Premium Member join:2006-04-15 Holly Springs, NC	j1349705 to Vince6 Premium Member 2013-Jan-9 9:08 pm to Vince6 Your upstream power level looks good, but there could be noise or some other issue causing problems which could only be seen at the CMTS (on Time Warner's side). Have you tried calling support? You may have to demand for your case to be escalated if the first level of support can't help, but it makes sense to see if they can see anything on their side before you spend too much of your time on this. One observation... you have upstream channel bonding, which is something you did not have on your old Toshiba modem. That is a factor other than the modem that is different and could be somehow contributing to your issues. This modem has proven to be pretty reliable overall for many service providers in many areas. There's always the chance that you have a bad one, but I think it is unlikely.

Tundra18 join:2013-01-10 Norfolk, VA	Tundra18 to Vince6 Member 2013-Jan-10 5:12 pm to Vince6 I'd get rid of the modem just because it is a Zoom. Might not cause you problems, but I've seen a lot of them emiting 5 spikes anywhere from 5-30 MHz and cause problems for others. What speeds are you supposed to have?

Vince6 join:2013-01-08	Vince6 Member 2013-Jan-10 5:53 pm jimk - I haven't called support yet. I Wanted to get some input from everyone here before I did that. That and I dread having to talk to those people. Tundra - I believe the speeds are marketed as 20/1. It's not really the speed that is the problem it's how unstable it seems to be along wit the large fluctuations in lag when gaming and the occasional drop out.

Radisc359 join:2010-10-02 Fremont, NE	Radisc359 Member 2013-Jan-10 6:15 pm As jimk pointed out you have upstream bonding, with an ATDMA 5120 wide upstream channel even which needs an SNR of 30 or else it could cause random dropouts or other issues. The only way to read that SNR of the upstream channels are at the CMTS and even then its an average. Ever ask to talk to Tier 3? Although they can only do so much they are far better then Roadrunner National Help Desk, which on occasional has made me say ugh.

Vince6 join:2013-01-08	Vince6 Member 2013-Jan-10 8:35 pm I figured I would give the TWC online chat support a try, but of course it was a waste of time. He couldn't access the head end to give me the upstream SNR numbers. He tried the standard "let me send a refresh signal to your modem". That didn't do anything. I kind of lost faith when he told me to keep the chat window open while I rebooted my PC. One thing he did have me try that I hadn't though of was to disable the antivirus and malware software. While this didn't solve teh unstable ping problem, it did seem to increase my DL speeds. It didn't help with the UL speed though. Here are my numbers with them disabled: 51.97 .15 27ms 57.48 .97 24ms 44.59 .96 35ms If I feel like being tortured this weekend I'll give the local number a call and see what they have to say.

You need tier 3 support. Everyone else will just tell you to reboot the modem until you get annoyed and hang up. You might still have to go through the initial troubleshooting before they will transfer you. Some reps refuse to transfer in which case you may have to call back to talk to someone else. There is most likely a signal issue on the upstream that you can't see. The only upstream info you can see is what power level your modem is running at, which is one of many factors that can impact your connection.

Vince6 join:2013-01-08	Vince6 Member 2013-Jan-12 3:34 pm I gave them a call today and after a while I eventually got to a level 3 tech. He said that everything looked good on their end. In fact he said I had some of the best levels and SNR's he had ever seen. He said it is most likely the modem and I should get a new one. I asked what he thought about me trying one of their modems before going through the hassle of exchanging mine and he said it was a good idea and even gave me a $4 credit which covers their rental fee for a month. The office was closed by the time I got there so I will swing by Monday and pick one up.

Vince6	Vince6 Member 2013-Jan-14 6:23 pm I stopped and picked up a modem from TWC today. They gave me a Ubee u10c018.80. I just got it hooked up and even though the DL speeds seem slightly lower(could just be a lot of traffic right now), the UL speed seems much better and more consistent. Now my question is: Is my Zoom modem definitely bad or could it still be an issue with the upstream connections? The Ubee is only DOCSIS 2.0 while the Zoom is 3.0.

It could still be an issue that only impacts DOCSIS 3.0 modems. Therefore you really need to see if they will give you a DOCIS 3.0 modem to test with. Anything else isn't comparing apples to apples.

Radisc359 join:2010-10-02 Fremont, NE	Radisc359 Member 2013-Jan-15 9:22 pm In my case, they need to have an engineer look at the codes for this modem, because something isn't kosher with their system and this modem. A temporary solution would indeed to get a different modem and see if the disconnections go away. Now tier 3 can only do so much, for my issue they are now monitoring it to look for patterns in the drops when it sends a DHCP request then fails disconnecting us for like 10-30seconds every ~2.5days. You can have great signal and have a modem that is not configured correctly, but it takes so long for them realize the error. My recommendation would be to get a $4 dollar credit for a month and try one of their Docsis 3 modems and see if the problem goes away.

How did you get anyone to bother looking at the issue where the connection drops every 2.5 days after the DHCP failure? I have the same issue, and they don't seem to be interested in helping me. This isn't the worst issue I have seen with a cable modem... it is certainly annoying, but at least it doesn't completely hang and require a power cycle to restore service. I have also found an unrelated firmware bug on version 5.5.4.4J (patched in 5.5.4.9J). I'd rather not disclose the nature of the bug on a public forum. Time Warner Cable refuses to push the update, insisting that customers can install it themselves (which is not true), and that Time Warner Cable never updates the firmware of customer owned modems. This makes me wonder why they even bother with an approved device list. Firmware updates on cable modems are rare, but sometimes necessary. I have spoken to tier 3 multiple times.

Radisc359 join:2010-10-02 Fremont, NE 1 edit	Radisc359 Member 2013-Jan-16 2:57 am Actually my I've had three customer owned modems, my first SB6141(unused) acts like its overloaded or overheated randomly while speedtests show fine, my 2nd SB6141(returned) had odd disconnects with large jumps in codeword errors. This Zoom works so much better. Also they aren't monitoring it for the dhcp error thing, I was told the downstream crashes, while it adds it to the upstream. That's what Tier 3 told me the last time I talked to them. So the guy put my modem on a monitor, and that someone would get back to me if they saw a pattern. I know they can't read the correctable/uncorrectable errors on the Zoom, so they may not even be able see the snmp log. I'm just sick of bugs and just want a modem I can leave on and have it stay up without a dhcp failure or any funniness.

I'm just sick of bugs and just want a modem I can leave on and have it stay up without a dhcp failure or any funniness. I think they can see the SNMP log... the most helpful tech that I talked to said he saw the same errors I was talking about. Regarding getting a stable modem, I think that might never happen. Every modem has an occasional firmware bug... usually they don't impact everyone (sometimes they only impact people on one brand and model of CMTS). TWC's outright refusal to even consider updating firmware on customer owned modems means it will always be luck of the draw... if you buy a modem with perfect firmware, you will be OK... unless TWC makes network changes that expose a bug. In that case, be ready for the run-around, with the fix being to buy a different modem and hope for the best. This also shows that the own your own modem program exists purely to get people to stop complaining about the fee, and that they don't take it seriously and don't intend to support modems on the list of approved customer owned devices. I just wish we could apply our own firmware updates. I have never seen a cable modem that intentionally allowed this, most likely due to security reasons (for example, they wouldn't want someone loading custom firmware that ignores parts of the config file that is sent on startup). Going back to a rented modem isn't a solution either. I didn't buy my modem just because of the fee, I bought it because I don't want to be stuck with whatever random beat up used modem they feel like providing on any given day, especially since some of the DOCSIS 3 gateways are a bit of a PITA to deal with in bridge mode (I'm thinking specifically of the Motorola SBG6580). I just want a plain modem, no router, no wireless, just a bridge. My pfSense router beats the hell out of any integrated cable modem gateway product.

Vince6 join:2013-01-08	Vince6 Member 2013-Jan-16 9:40 pm So I'm thinking I should just get a new modem. DO I take a chance with another Zoom or go with a SB6121 or SB6141?

I still think the Zoom 5341J is a good modem overall, but since you have already tried one and have had major issues, it would make sense to try a Motorola SB6141 or SB6121 instead.

Motorola SB6141: DOCSIS 3.0 8x4 Motorola SB6121: DOCSIS 3.0 4x4 I believe both have a MoCA filter built in. These modems are based off a different chipset than the Zoom 5341J.

Vince6 join:2013-01-08	Vince6 Member 2013-Jan-18 6:57 pm Got it. Thanks. I'll probably go with the 41 to be more "future proof". It's only ten bucks more.
