I too am having this issue again, last month they fixed it by splitting up a node I was on and my speed was back to normal. I had a tech come out yesterday and he contacted his supervisor to see if there were any issue regarding slow speed in my area. According to his supervisor they know about it and yet have to find out why its happening. Told me to hang in there till they figure it out and credit my account. This is getting frustrating as the last fix barely last a couple weeks.
Well, I had a tech call scheduled the other day when I discovered that turning off my AVG antivirus (disable for 10 min menu option) allowed me to immediately jump from 70 to 100MB down. Turned it back down and I was at 70MB again. Turned if off and it jumped to 100MB.
If you are running AVG, turn it off and test. If it is a problem for you, replace it with something else. I canceled the call and had high speeds until the evening when it usually drops regularly. Now I am in the same boat and have to call them out. If you have not done a test in safe mode, do that and see what results you get.
i'm having the same thing, rarely get above 35 mbit, have been fighting with them non stop. they seem to think everything originates at my home, even though down a few blocks away probably on the same node, there are slow downs at the same time i have slow downs.
I too have the 100mb service. I consistently get 95 day or night. My signals are in spec Rx -12 to +12 and TX 35-50. I like to keep mine in the middle at 0 and 41. The main thing with speed issues is the upstream SNR. You can find this by loging into your modem and checking your levels.
You can have a SNR issue at your house or down the street at another persons house. If your nodes are combined at the headend then the bad SNR could be from another node nowhere near you. There is a constant battle from the charter techs in the field to fix these problems but all it takes is for a person to hook up their RV and the SNR issues start. Slow speeds for internet and dropped calls and echoing on phone are some tell tale signs an issue is happening. It is a tricky thing to find sometimes. It can be caused by a sump pump next to a loose cable connection or a balast in a floresent light going out. These noise emmiting events can come and go. I have seen it that the problem only occurs when a guy is using power tools in his garage between 5pm-7pm. By the time we track it close enough it goes away.
I had the issue described. My upstream SNR values would drop extremely low starting at 8:00 PM to 11:30 PM on Tuesday and Thursdays. The challenge I had was getting anyone to investigate it during the off hours when it was happening. Any advice on how to get the attention of someone when this is happening?
After lots of discussions with Charter Direct, I finally had the issue resolved and was told that someone in the next neighborhood was causing the issue.
I wrote a script (for Linux), that does a command line test to whichever local speedtest.net site has the least latency and stores the values in a file with a timestamp. I have configured my Splunk system to read that log in so I can create some dashboards and reports. I have a dashboard that shows the highest and lowest download speeds over the last 24 hours. I am going to find me a charter support email address that I can send this to so someone can see what times I am having the worst problems and see if they can help me.
I have the same problem on a 100/5 connection... The phone service drops calls or is garbled to the point that I have not used it for three months, and the internet is bad at all different times of the day but mostly drops to crap around 7pm local time then picks up in the morning but not always. The funny part is that the TV service works well 90% of the time. Sadly I felt like I was finally getting somewhere with direct support. After five truck rolls direct support told me an engineer was headed down to fix a problem they found in the node. Direct support then told me that they would have the systems engineer call me to explain the problem and the time table to repair it.
That was in November and direct support is now dead...
I have only had service for the last four months and this is a house that had never been connected to cable from the tap... It is the same thing every time, I call they send a tech who says hmm something is weird and then I never hear from them again...
I asked them if it looked like an overloaded node and was told no, and that I was one of two people on the node with 100/5 service.
The speed test to their site goes up and down while testing and looks like someone revving and engine. Almost anything real-time fails to work for very long including my separate VoIP line.
Previously (before I move here) I had Comcast extreme 105 service and never had a single problem.
The other thing I find funny is that even when it tests to their internal speed site ok, nothing else outside their site tests higher than 20-35mb down 3-4mb up... What is the point of a premium speed service if the speed in basically fast only inside their own network?? It is like having a 1gb lan connected to 10mb wan or a fast car that loses 70% of it hp when I drive it off the showroom lot, wth is the point? Do I just toss in the towel?
I finally got someone out to my place to check on things. Within 5 minutes, they knew the problem was not at my house. They sent out a line tech last night that found a problem at the headend. He has put in a request for repair/replacement. We will see how long this takes.
