Random Internet Connection Drops
I have been experiencing numerous drops daily for several months.If you check the notes on my account,I have been encountering this issue even prior to everyone working from home. I am in section 1558A (according to last phone contact) and there is no current activity to attribute this behavior. Disconnection events are more numerous in the morning and can last anywhere between 30 seconds to 10 minutes but have been noted to occur unexpectedly throughout the day. The triggering events have not developed into a recognizable pattern from my side not noted from your tech support. I have recently replaced and equipped a new Arris Surfboard SB6190 at the strong suggestion of online tech as the prior model aged out of service. There was NO CHANGE in connection behavior. The frustration of having to callsupport eachtime is overwhelming and is prominent enough to cause issues with my work which is heavily reliant on a stable connection. I have had since to rely on using my cell as a hot spot and while this proves to be a workable alternative,should not have to be used because I subscribe to a service that is supposed to provide this for me.I have lost countless man hours working around and through this issue. I would hope that your tech team would display working as tirelessly towards resolution. If there was an viable alternative, I would be looking into changing. Please fix this. -Kurt

What else could it be? Connectivity Dropouts
So I've been having problems with intermittent internet for some time now. The modem seems to take a hit a few times a day and I get one of a variety of errors. I had a technician come out and evaluate the system, and all seemed fine so he concluded that the modem must be bad. I have purchased a new modem and still get dropouts. I'm trying to come up with answer for what could be driving this.... Here are a sampling of errors on my Netgear CM600 2018-06-09, 02:23:17 Critical (3) Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;CM-MAC=b0:39:56:00:ce:90;CMTS-MAC=00:c1:b1:61:3d:cf;CM-QOS=1.1;CM-VER=3.0; 2018-06-09, 02:22:45 Critical (3) Unicast Ranging Received Abort Response - Re-initializing MAC;CM-MAC=b0:39:56:00:ce:90;CMTS-MAC=00:c1:b1:61:3d:cf;CM-QOS=1.1;CM-VER=3.0; 2018-06-09, 01:23:27 Critical (3) Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;CM-MAC=b0:39:56:00:ce:90;CMTS-MAC=00:c1:b1:61:3d:cf;CM-QOS=1.1;CM-VER=3.0; 2018-06-09, 01:23:15 Warning (5) Unicast DSID PSN startup error Here is my signal outlook at this moment Procedure Status Comment Acquire Downstream Channel 795000000 Hz Locked Connectivity State OK Operational Boot State OK Operational Security Enable BPI+ IP Provisioning Mode Honor MDD IPv4 only <tabindex=-1>Downstream Bonded Channels Channel Lock Status Modulation Channel ID Frequency Power SNR Correctables Uncorrectables 1 Locked QAM256 3 795000000 Hz 6.4 dBmV 40.3 dB 2 0 2 Locked QAM256 1 783000000 Hz 6.6 dBmV 40.3 dB 0 0 3 Locked QAM256 2 789000000 Hz 6.5 dBmV 40.3 dB 0 0 4 Locked QAM256 33 357000000 Hz 1.9 dBmV 39.5 dB 32 1 5 Locked QAM256 4 801000000 Hz 6.3 dBmV 40.1 dB 0 0 6 Locked QAM256 5 807000000 Hz 6.2 dBmV 40.1 dB 1 0 7 Locked QAM256 6 813000000 Hz 6.2 dBmV 40.0 dB 0 0 8 Locked QAM256 7 819000000 Hz 6.1 dBmV 40.1 dB 1 0 9 Locked QAM256 8 825000000 Hz 6.0 dBmV 40.2 dB 1 0 10 Locked QAM256 17 879000000 Hz 5.3 dBmV 40.2 dB 1 0 11 Locked QAM256 18 885000000 Hz 5.0 dBmV 40.1 dB 0 0 12 Locked QAM256 19 891000000 Hz 4.8 dBmV 40.0 dB 0 0 13 Locked QAM256 20 897000000 Hz 4.7 dBmV 40.0 dB 2 0 14 Locked QAM256 21 903000000 Hz 4.7 dBmV 40.0 dB 0 0 15 Locked QAM256 22 909000000 Hz 4.7 dBmV 39.9 dB 0 0 16 Locked QAM256 23 915000000 Hz 4.7 dBmV 39.9 dB 0 0 17 Locked QAM256 24 921000000 Hz 3.8 dBmV 40.3 dB 0 0 18 Locked QAM256 34 363000000 Hz 1.5 dBmV 39.4 dB 0 0 19 Locked QAM256 35 369000000 Hz 1.4 dBmV 39.5 dB 0 0 20 Locked QAM256 36 375000000 Hz 1.6 dBmV 39.6 dB 0 0 21 Locked QAM256 37 381000000 Hz 1.4 dBmV 39.4 dB 0 0 22 Locked QAM256 38 387000000 Hz 1.3 dBmV 39.5 dB 0 0 23 Locked QAM256 39 393000000 Hz 1.1 dBmV 39.3 dB 0 0 24 Locked QAM256 40 399000000 Hz 0.4 dBmV 38.6 dB 0 0 <tabindex=-1>Upstream Bonded Channels Channel Lock Status US Channel Type Channel ID Symbol Rate Frequency Power 1 Locked ATDMA 1 2560 Ksym/sec 17600000 Hz 45.3 dBmV 2 Locked ATDMA 2 5120 Ksym/sec 25800000 Hz 46.3 dBmV 3 Locked ATDMA 3 5120 Ksym/sec 32200000 Hz 45.5 dBmV 4 Locked ATDMA 4 5120 Ksym/sec 38600000 Hz 46.3 dBmV 5 Not Locked Unknown 0 0 Ksym/sec 0 Hz 0.0 dBmV 6 Not Locked Unknown 0 0 Ksym/sec 0 Hz 0.0 dBmV 7 Not Locked Unknown 0 0 Ksym/sec 0 Hz 0.0 dBmV 8 Not Locked Unknown 0 0 Ksym/sec 0 Hz 0.0 dBmV I've gotten to the point where I am just randomly replacing cables... i'm not sure where i'll end up but in any case I work from home so this puts a real hamper on my day.

Awful through-put
Is there a reason why my through-put drops to ZERO three or four times each hour? Is there a way for Cox to monitor and hopefully correct this?

Internet Dropout with Airport Extreme & Motorola SB5101N Modem
So I was attempting to download a large game via Origin, about 8GB in size, and my connection was "interrupted" or "dropped" about 10 times during the whole download. I've noticed that the internet tends to cutout for 1 - 5 minutes, particular when requiring a lot of bandwidth, such as downloading large files. All the devices are affected, not just my laptop and I cannot access anything on the internet. We are using an Airport Extreme (the flat one, not the tower looking one[new]) and a Motorola SB5101N modem and we have the high speed internet package. When I get these "dropouts", the modem shows that it's receiving and sending information, in other words none of the lights go off (as far as I know). The Airport Extreme however sometimes shows a flashing amber-yellow, instead of a solid green light. When I go to my network diagnostics utility software, it goes through a series of checks; WiFi, WiFi Settings, Network Settings, ISP, Internet, Server (in that order). During the "outages" the last two, 'internet' and 'server' turn yellow. Not sure what they mean, but wanted to see if anybody else ran into these issues. I would think it would be either a router or modem issue, but I don't know how to troubleshoot them since I don't have anything to replace them. I've tried looking through the Apple forums, but haven't found a solution. Any help would be gladly appreciated.

T3 and T4 Timeouts from an ex-field technician
Starting in September of 2013, I noticed my connection becoming intermittent at best. Voice conferencing and gaming would literally go from 23 ms to over 10k ms and then obviously I would disconnect from the server. About a week after this first started happening, it started to randomly disconnect while I was simply browsing the internet. I found the modem was cycling itself. At the time I had an extremely old but trusty Motorola Surfboard SB5100. Despite having this modem throughout the DOCSIS 3.0 updates, and despite it having worked fine through it all hither to the point in time, I figured it may be the modem (after a 12 year run, I wasn't complaining...) I accessed the modem diagnostic page at 192.168.100.1 and saw that in the logs there were massive amounts of T3 timeouts. Being an ex-field technician for Cox, I knew this could have gone one of two ways. It was either the modem or it was something in the node (most likely an amplifier in the trunk line) that was to blame. I called Cox for the heck of it just to see if they could see anything on their end, and as usual, no. Everything on their end was fine, but again, having been a field tech for 5 years, I know that phone based customer service is very limited, they're not at the house, they don't have a meter and they're sure as heck not taking level readings. Ok, fair enough. I purchased a Motorola Surfboard SB6141 to replace the 5100 and finally upgrade to DOCSIS 3.0. I called them, had the modem provisioned, went to the diagnostics page, was "wowed" by 8 downstream and 4 upstream channels, wondering why I had not upgraded the modem sooner, but alas, not 2 hours after provisioning, there was a T3 timeout. Now I know it's not the modem, time to get on the phone and make things happen. I called, they said they would send a tech out. The tech (CONTRACTOR) came out and I explained the whole situation to him. I showed him the modem diagnostics, I explained what I knew about everything, and he agreed with me. He did NOT check levels, he did NOT check the tap at the pole (I have a 340 foot drop from the pole to the house, it's RG-11. A new install was done less than a year ago, including the drop and inside lines, and I told him this, so he probably "assumed" things were good up there...). He scheduled a 5C, which is the "internal" code name for "get a maintenance (plant) technician out to the pole to see what's up". I got a call from my old lead technician about a week later. He told me that the maintenance tech found water in the drop and cut it back to where the "stinger" (copper in the connector) wasn't black from water damage, and that another tech would be out in the next day or two in order to run a new drop. Two days later ANOTHER CONTRACTOR comes to the house to run the new drop. I saw his spool of RG-11 and I knew he didn't have enough left to get from the pole to the house. He removed the drop at the sub pole, and due to not wanting to bother him, I came back inside. 20 minutes later I went back out and he was gone. He never replaced the drop. He probably figured he didn't have enough cable to do it after removing the drop at the sub pole, rehung it, and left. This pissed me off. In the meantime I contacted my old lead and asked him what the deal was, explaining that not only were these T3's still happening, but they were getting worse, and they were leading into T4's. He scheduled for the drop to be re-run AGAIN the next week and made sure it would be an in house guy arriving, NOT a contractor. Sure enough, another lead technician and a field tech came to the house and ran a new drop. They didn't have enough RG-11 so they ran half RG-11, then installed a ground block at the sub pole and ran RG-6 the rest of the way. He said he would be back (this was a month ago and it still hasn't happened) to replace the RG-6 half of the drop with RG-11. He gave me his cell number to contact directly if this kept going on. It kept going on. The T3's were getting worse. I asked him on the phone to set up a 5C, he said he would but this was a week and a half after he replaced the drop and hadn't been out to finish the RG-11, so my faith in relying on him was null. I therefore called customer service. I explained that, despite having JUST bought a new modem, FIOS was a phone call away if this wasn't resolved. Per usual, they went RIGHT back to square one and wanted to send out a tech. I told them to stop reading the script from their screen and focus on their keyboard in order to LISTEN AND UNDERSTAND exactly what I had JUST explained to them. For over a month I was implying that this was a plant issue, no one wanted to listen. The phone techs didn't want to listen, the lead techs did not want to listen, the lead techs kept coming back with 50 other excuses as to what could be causing it. I questioned them as to why they would do this when they knew I used to be a tech and I wasn't an idiot. The final call was made to customer service. Again, they said they had to send a tech out, despite two months of this **, in order to get a 5C scheduled. Ok, last time I am playing this game. The tech came out and I caught him on my way home from work. He was an in house guy and I caught him as he was at the pole taking levels. He told me that every port from the tap was bonkers, he replaced the tap and the levels were STILL bonkers, and that he did not understand how two lead techs and four field techs didn't realize this was a plant issue from day one. I concurred. He took down every piece of information I gave him about the new drop, the new modem, signal levels at the modem, etc, etc, and made a detailed log for the maintenance techs who came out. He also told me that there are only SIX HOUSES ON MY NODE, LITERALLY. This means that the trunk line feeding my house only feeds a total of 6 houses. Do you know how easy that is for plant (maintenance) to troubleshoot? There is one amplifier that is literally humping my tap, if here's an inch of trunk line from the amplifier into the tap then it's a lot. I suspected that amplifier from the get go, but even if it wasn't, there would only be at most ONE MORE amplifier in that node, so yeah, one amp checked out good, guess which one's bad? Real easy stuff here people, real easy. So, the tech scheduled the 5C (the second one that had to happen in this whole fiasco), and the maintenance tech came out. I don't know if it was the same or a different one, but this time around (after TWO MONTHS OF THIS **) the problem was resolved. It has been two weeks and I have not seen a single T3 or T4 in my log. I see where it lost connection due to the maintenance guy doing what he had to do and of course the service gets interrupted during this, but honestly, after the modem cycle, there is not ONE added entry to the log, nothing; whereas every other "visit" would result in a T3 less than 10 minutes later. These T3 (and later T4's due to the issue getting progressively worse) were happening every ten to twenty minutes on some days, other days every hour or so. I use VOIP for telephone. Imagine not having 911 access for the whole day because your ISP can't get it's act together. I held out having FIOS reinstalled (it was installed here when it first came out) because I honestly can't stand those hacks. Having said that, had that last tech not been so thorough, had the second maintenance tech not done his job and resolved the issue, Verizon was seriously the next phone call. I didn't go into a whole lot of detail about levels and diagnostics here because I did enough of that with customer service and all the techs that visited. I wanted to make a point here to Cox. Not all customers are complete idiots. Not all customers have zero clue about how information travels from their house to the MTC. Maybe instead of treating everyone equally as morons, you should start treating them all equally as intelligent folk. Imagine how many folks out there were never field techs, imagine how many would have switched back to Verizon within the first week, let alone sticking it out for two months. I was a field tech, I have working knowledge of the system, I was treated like a complete idiot, how do you think that makes me feel? It actually makes me feel pretty damned good right about now knowing I was right the whole damned time about the issue being a plant related occurrence, but I can tell you right now when these people tell you over the phone and face to face that you're "wrong", and that they need to go through steps that, again as an ex-tech, you KNOW they don't need to go through, all the while the internet that we pay for monthly and (in some cases) our phone service (through another provider in my instance) has fallen to complete useless garbage, labeling it as "infuriating" somehow undermines the true nature of it. I know that not every single problem faced is one of a plant issue, this is obvious. Red flags should be raised, however, after every single other step has been taken and fails, instead of attempting to loop the same damned process all over again; that is simply ridiculous. What is also ridiculous is the fact that contractors are being sent in place of in house technicians and basically this leads to repeat trouble calls. This is something that is completely unacceptable, especially when one has to take time out of their day (or out of work) every time a call has to be rescheduled. I know not every contractor is a bad contractor, but out of the entire bunch, I can name 3 that I would have work at my house, that's about it. To make it relative to the in house technicians, I can list about 20 off the top of my head that I would let work at my house from start to finish with a cable job any day of the year. I hope this type of issue, or at least the steps to the resolution of this type of problem does not happen again. I will definitely be more prone to calling Verizon early on if an issue is not resolved in a suitable amount of time, not TWO MONTHS AFTER.

Connection Lost/Service Drops
Ok Cox, I am going to give you one last try. I have had this same problem, for MONTHS now. We have purchased a couple of new modems, and several different and new wireless routers, and still intermittent "drops" if you will orinterruptionsin service. Eachinterruptionlasts for probably about 4 minutes, give or take, and then automatically restarts on it's own after this time. This has happened at least 4+ times to me just today alone, on a Saturday. We have contacted Cox several times on this issue, and you always blame it on our equipment. Well, after replacing our equipment a couple of times now, I am really not believing that it is our equipment, but Cox. My wife has had to stop working from home, because she cannot put up with these interruptions in service while working from home. I need a real and final solution to this problem, or I will have to take my business somewhere else. I contacted one of your reps via chat, but guess what? We were interrupted by a service outage, or dropped connection. Very frustrated with this issue. Tim

Internet Service Keeps dropping
I had an old SB5101 and was having to reboot it every few days to re-establish the internet connection. I searched on these forums and found out about the new DOCSIS 3.0 modems and how they were solving some of the connection drop off issues for some other customers. I bought a cisco DPC3010 modem to replace the old one and at first everything was great after I set it up. I did a speed test and both my download and upload speeds improved significantly over the older modem. Then, after two days my computers were reporting they didn't have any internet connections and the new DPC3010 had a blinking online light. I cycled power on the modem and everything was restored once it came back up. Now, the modem is loosing connection a couple times a day and requires I have checked the connections to the modem and everything looks good. I logged into the modem when it had a connection and the status looked good with all 8 X 4 connections This is so frustrating. I got the new modem because I thought the drop off issues were caused from the outdated technology in that SB5101. I am now thinking there is something wrong with my account or connection. I am hoping someone has some advice as to how I can correct these issues so my internet service doesn't drop several times a day. thanks in advance for you help, John

High downstream and upstream power levels
I have seen post about high downstream and high upstream power levels but not at the same time. It seems to always be that only one of the levels is high and the other is low. I am having both high at the same time. Here are my normal readings. Downstream is normally around 8 to 9 dBmV Upstream is normally around 53 to 54 dBmV What could case both to be high at the same time? I am asking because I am having problems with online gaming. Server kicks, lag, ect. Thanks

Router dropping all the time
I have my own Motorola SBG6580 on Cox Internet service. Our Internet connection drops all the time, 3 times today already. Sometimes it reconnects itself in a minute or two, sometimes I have to reboot the device. I called tech support and they said they didn't see any issues in our area and senta reset signal. This has been going on since we moved into this house a month or so ago. Below are some of the logs I see, which sounds like a lot of people are getting with this modem. Is this a bad modem/router to have purchased? Or do these logs show something wrong with the connection to Cox? By the way, you'll notice inthe last 2 entries, one say Time Stamp Not Established, those last two entries change every time this happens but it never retains the log from the previous error. Any ideas?
