Understanding Router's Error Log
I'm a Cox customer in Wichita, KS and am using a SB6850 Router. Here's the error log for the about last week: I've read that some of these errors aren't serious but am concerned about the "T-3" errors. Do the "T-3" errors indicate that my internet service is being interrupted?
Connection Issues
I have been having chronic network issues for over 4 months now. At first I thought that my issues were purely due to the fact that I was experiencing issues when running my PC off of a wifi extender, but after setting up a new hard wire connection to my computer, I have been experiencing the same behavior that I had been seeing before. Also, my issues have not been limited to my computer. When connecting to my wifi network on my phone or TV I experience the same behaviors that I do when being connected via ethernet. I now keep my network graph constantly open on one of my monitors so that I can take a screenshot of it whenever I experience issues. Since October 7 of this year I have over 240 screenshots with each showing the same behavior. I will be operating like normal and then I will experience a sudden loss of network quality to the point of not being able to load basic web pages. There are hardly every any noticeable symptoms that can show that I am about to lose connection, most graphs are healthy for whatever operation I happen to be performing at the time whether that be video streaming, downloading, or playing online video games. The constant issues have becoming an increasingly annoying detriment to my daily routine and have even prevented me from being able to play most online games out of fear that I will be kicked from the match to a loss of connection and will face penalties for perceived poor teamwork.
Internet disconnection
Hi, my internet recently started to disconnect many times, especially when I was playing Dota2. The wifi was also unavailable when the router disconnected. So I went to Cox store and exchanged my router and reinstalled the Windows on my desktop. But nothing changed. I got disconnected yesterday while playing Dota2. Please help.SYNC Timing Synchronization failure - Loss of Sync - Slow Speeds, Drops, etc
Hello, I have the "Ultimate" Internet tier and over the last few days, my service has been atrociously bad. There are times when I get close to the speeds I am paying for and other times not even close. I was wondering if my power levels on my modem were in-spec? Also, seeing quite a few of the following log messages in my modem: SYNC Timing Synchronization failure - Loss of Sync Started Unicast Maintenance Ranging - No Response received - T3 time-out MDD message timeout Downstream Bonded Channels Channel Lock Status Modulation Channel ID Frequency Power SNR Corrected Uncorrectables 1 Locked QAM256 22 909000000 Hz 8.7 dBmV 39.0 dB 164583 338195 2 Locked QAM256 1 783000000 Hz 10.2 dBmV 39.9 dB 0 0 3 Locked QAM256 2 789000000 Hz 10.2 dBmV 39.8 dB 0 0 4 Locked QAM256 3 795000000 Hz 10.0 dBmV 39.7 dB 0 0 5 Locked QAM256 4 801000000 Hz 10.1 dBmV 39.8 dB 0 0 6 Locked QAM256 5 807000000 Hz 10.0 dBmV 39.8 dB 0 0 7 Locked QAM256 6 813000000 Hz 9.9 dBmV 39.8 dB 0 0 8 Locked QAM256 7 819000000 Hz 9.9 dBmV 39.8 dB 0 0 9 Locked QAM256 8 825000000 Hz 10.0 dBmV 39.9 dB 0 0 10 Locked QAM256 17 879000000 Hz 9.5 dBmV 39.5 dB 4 0 11 Locked QAM256 18 885000000 Hz 9.4 dBmV 39.4 dB 1 0 12 Locked QAM256 19 891000000 Hz 9.2 dBmV 39.3 dB 3 0 13 Locked QAM256 20 897000000 Hz 9.2 dBmV 39.3 dB 2 0 14 Locked QAM256 21 903000000 Hz 8.4 dBmV 39.0 dB 182726 774664 15 Locked QAM256 23 915000000 Hz 9.0 dBmV 39.0 dB 201227 812336 16 Locked QAM256 24 921000000 Hz 8.9 dBmV 38.8 dB 612277 1054773 Upstream Bonded Channels Channel Lock Status US Channel Type Channel ID Symbol Rate Frequency Power 1 Locked ATDMA 2 5120 Ksym/sec 23300000 Hz 37.7 dBmV 2 Locked TDMA and ATDMA 1 2560 Ksym/sec 18400000 Hz 38.3 dBmV 3 Locked ATDMA 3 5120 Ksym/sec 29800000 Hz 39.8 dBmV 4 Locked ATDMA 4 5120 Ksym/sec 36300000 Hz 41.3 dBmV Current System Time:Sat Oct 14 11:56:41 2017Multiple connection timeouts happening every few minutes
I have been having multiple connection timeouts while using my service, usually happening every 5 minutes. I can't enjoy my online gaming for more than that time without being disconnected from the servers. I have tried everything from unplugging the modem for a few minutes then plugging it back in, having the modem's power go directly into the power outlet, replacing the rental modem that I was using with a newer and faster one, being directly hardwired into the modem and not using the router, changing DNS servers, and flushing the DNS. Cox even sent a "technician", though he was only contracted, to my home to check my wires. He said everything looked fine. Yet the problem persists. This problem has been going on for more than year now and I'm extremely frustrated and just lost on what else to do. Any help or advice would be greatly appreciated. Thank you.RE: Outgoing SMTP Issues Suddenly occurring
The link above is not the correct one. The issue is a false problem that appears on android phones. First, try to send an email to yourself from cox.net. If that does work, ignore the "Can't log in" repeated error message. OK, so how do I attach this to your thread, there is no link?? Forum: Internet Forum Posted: 16 Aug 2016 Post Subject: RE: Outgoing SMTP Issues Suddenly occurring Post author: ChrisL @GrowlerGuy For starters, are you able to send via our webmail? If that works I suggest removing and re-adding your client device SMTP setting as per the following article and see if that works: http://www.cox.com/residential/support/internet/article.cox?articleId=334d7950-31f8-11df-fe42-000000000000
Internet nearly unusable
A few months back, our internet would stop working every now and again. No big deal, just reset the modem. Didn't give it much thought. But then "every now and again" became weekly. Then daily. Now we're lucky if the internet sticks around for a solid hour without requiring the modem to be reset. We tried to watch the new Amy Schumer special on Netflix, and our internet pooped out three times during one 50 minute special. The problem affects all of our devices - PC, smart TV, smart phones. And the modem, which I have come to hate, continues to have all its lights solidly on, as if it has no idea there's a problem. Our phones don't, either. They think they have Internet but they don't, so they don't even switch over to Sprint LTE. All the connections seem fine to me (but what do I know?), nothing seems like it's overheating... The modem's less than a year old, it should still have some vigor left in it. I got on cox.com and reset the modem from there, too. Didn't work. I don't know what's going on... Can anyone help me?Erratic Internet Service with slow speeds
Been experiencing problems with this Cox Premier Internet using a DN4500B. I connect my MBP wirelessly. The speed testresults are 82.76Mbps DL and 17.13Mbps UL. Many times I have to reset either the modem and/or my MBP. My TV is wired and outages are experienced that may last anywhere from a second to a few seconds. Please advise.!!!!---Constant Internet Speed Issues---!!!!
Since I have had Cox I have had constant connectivity issues. Our modem has been upgraded to the Netgear N450 CG3000Dv2 to assist with our previous connectivity issues. We were running at 15 Megs on our previous plan and had constant speed of 8 Megs MAX. I just upgraded our internet to 50 Megs and we are lucky to get 2 Megs of download speed on a good day. We are paying almost 2x the prior cost for a slower speed. I checked our modem compatibility and it states the hardware can process up to 150 Megs of download speed. I have hard RESET the modem and RESET the connection on the online tool multiple times now. I understand Cox to be more reliable than other internet providers. Their customer service is extremely friendly, but unfortunately I have not been able to have any of these issues resolved. I have our most recent speed test provided below. Of which, I see it doesn't show up. Basically, it details we are running at 1.66 Megs on download and 2 Megs on upload. Our upload speed is faster than the download! Any advise or information would be greatly appreciated.
slow internet speed and no access often between 7pm to 9pm
I have a reoccurring problem, slow internet speed and no interne access often between 7pm to 9pm. This also happens at a few other times at random, but almost daily at night. Does happen with devices connected over Wi-Fi and devices connected by LAN cable.
