Re: [AZ] Cox Internet speeds.

During the day time my internet speed is great.
»www.speedtest.net/result/385691871.png

As soon as I get home around 6pm I am lucky to get 128KB/sec down.

Any suggestions? Cox so far can't figure it out.

Happens everynight.

Name
WebSTAR DPC2100R2
Modem Serial Number
218131117
Hardware Version
2.1
Software Version
v2.0.2r1256-060303
Receive Power Level
2.5 dBmV
Transmit Power Level
41.0 dBmV
Cable Modem Status
Operational

The above numbers are always the same.

I realize that there will always be some type of congestion, but congestion does not explain a drop from 27Mbits/sec to 1Mbit/sec. Atleast I dont believe so.

Sorry about that, but I registered so reposting.

Here are my speed test results over the past 24hrs.

Re: [AZ] Cox Internet speeds.

AZwidcats, In windows 2000 and XP doesn't have any dynamically tune of congestion window buffer implemented, congestion window buffer size will be always be static and latency times will always be dynamically ups and downs of times and while congestion window buffer size static non-changeable and will lose congestion window stream while latnecy times clinbs up of larger packet delay time unless you are on windows vista, newer an TCP congestion window buffer can do dynamically in automatically tune as latency times are dynamically at same a time rather than old early TCP static of congestion window buffer in the windows 2000 and XP versions. Linux does have congestion window dynamically implantment as optional since 2.4 Linux kernel and now newer 2.6.xx Linux kernel have enabled of congestion window buffer dynamically, window scaling as automatically tune at default setting.

Larger congestion window buffer size with window scaling enabled really can help to keep congestion window from collapsing of data stream of broadband or dedicated high speed bandwidth in the packet delay times and the high latency of environmental.

, i apologize in advance crapping all over your thread (this is in no way directed towards you or Fubar

)...

when i first started reading these boards, i almost used to think he just a joke that someone was playing on us...

the longer and longer i go on, the more i think that he is a real person and actually believes what he spews...
my real 2009 wish (and i say this at the risk of getting modded) - Ikyuao

stops spouting off about "windows xp not have autotuning for congestion avoidance when tcp buffer steams across long fat pipe across internet" and will speak in perfect english.

If that web site is so far away in distant of 200 ms to 300 ms away from your home in long range of distance to japan country or foreign country so your 64K small congestion window buffer size will be much likely get collapsed of data stream that really definitely slow down and finally crawls down and lost completely. It's like if your the spacecraft ship wanted to go warp speed of inbound for Andromeda Galaxy that really 2.5 million years light away then your spacecraft will be definitely runs out of the fuel of dilithium crystalline and matter-antimatter energy then you and your crew will be definitely be killed in starvation and completely lost in space empty of floating. do you understand what I mean what I talking about congestion window buffer size, when having dealing with packet delay times as high latency environmental or maybe internet routers are too busy of buffer of packets as triggering latency increases of delay times.

I can access to sega.jp web site reachable in japan country really fast enough with larger window buffer.

The fact that Ikyuao is still here posting crap two years later or the fact that there are still people who haven't used the ignore feature to remove his garbage from their screens. It's posters like Ikyuao and jsmiddleton that make the snr of this forum too low for me to bother much anymore.

the issue here is that if everyone were to ignore, only those who need help and aren't familiar with his reputation can see his garbage. if no one interjects, then the user may try his solutions and have his setup puke more than it already is.

That's right, there is the way of hidden of the efficient of use broadband bandwidth via TCP expension of high performance. I bet that most colleges and universities will say that I'm correct about the high speed WAN link and latency packet delay times.

Re: [AZ] Cox Internet speeds.

I believe what Ikyuao is referring to is called "Flow Control" which takes place at the transport layer of the OSI model. I've included an article that explains it a bit more indepth and yes, this can have an affect on how fast a server and client communicate.

It took me a few tries to piece together what he was saying, but I believe this is it. Is this correct Ikyuao?

Re: [AZ] Cox Internet speeds.

Yes and having larger window side buffer really can handling better in high latency environmental of WAN networks also I usually testing my speeds over some sites in 25 ms to 100 ms delay times and larger window side buffer can keep track with latency delay times at the same level what I get speed in exactly this the way. However smaller buffer like 64K buffer and at higher latency delay time levels then standard 64K buffer don't be giving you much speeds because latency delay times can reduces speeds so greatly in effect. My Linux PC ---> My cable modem that's it so I can get much faster speeds without using router hardware device since Linux includes flexible iptables and ip6tables firewall functionality. Hope that helps. P.S. if 64K congestion window fills out a buffer at one ms RTT really definitely gives you up to 500 Mbits but unforateunly 64K congestion window can't stand at 100 ms delay and degrades to 5 Mbits speeds down that is explain. Unless if you start with 64M buffer at 100 ms delay that could gives you 5 Gbits speeds that is very simple

And smaller buffer and higher latency delay times will take longer time and higher buffer and higher latency delay times will take much less time to get there. smaller buffer at higher latency delay times really definitely extrmemly inefficient for high speed broadband WAN link.

here's my test speed of bewteen my home in Wichita, KS and test speed site in Denver, CO over 400 miles of distance in about 100 ms delay with greater congestion window side buffer that gives me greater speeds that is very simple

So I can ignore packet delay as same as packet loss since larger window buffer are much sufficient enough.

Someday I will be professional IT either software programmer when I get into university school

Unfortunately, your english is extremely difficult to understand. Your sentence structure is backwards and missing important transitions. Perhaps you should increase your study of english until you improve?

Re: [AZ] Cox Internet speeds.

I'm sorry, You are wrong about TCP optional options of a about flow control as like window scaling, timestamps, MSS and SACK and can be combined with congestion control perfectly. I understand deeply perfect about TCP flow control that I get great speeds, it is not flawed. And Mod, please lock this thread up before this gets winds up a out of control like crazy.

Though I'll probably get blasted for saying it, but everytime I've seen this description on the forum, including in my own experience, it turns out to be just too many people in your neighborhood with probably a few of them doing heavy downloading. In my case, they doubled the node capacity to fix it and it really did work until just recently when they upgraded the speed again. I'm waiting a little bit before I complain again.

Update:

Finally got a technician to come out after hours, and they recorded the extremely slow internet speeds. The technician recorded the numbers from the street, so had nothing to do with inside my house. I am currently waiting for another service call, for someone to come out and figure out where the bandwidth is going. Unfortunately they dont have a time scheduled for when that will take place.

So atm I call in everyday so that my acct continues to show there is still a problem. Atleast that way, they discount my bill.

Almost 2 months to the day, my internet has been fixed. They split the node early this morning. So far it is much much better. Will need about a week of testing to be sure. It only took calling them everyday for it to be fixed. For the first month I had technicians at my house just about every day. When that didn't work I finally got quite a few of neighbors to start calling in every day as well. That seemed to do the trick.

Thanks all for your suggestions.

I have the same problems at night also. I doubt cox techs will come out at night which is when the problems occur. Latency and Bandwidth are absolutely horrible at night. Everything is pretty good during the day but nowhere near as good as it used to be. As I have posted before everything seemed to go to pot when On Demand was introduced to my area. I'm not sure if the bandwidth is shared but it still seems strange. I call and complain at least 5 times a week hoping it will get fixed. Based on what I have read here and elsewhere I'm pretty sure a node split is required to handle the problem.

mryanbrown join:2004-04-13 Glendale, AZ	Ikyuao I think it's very safe and certain to say that any TCP optimization on a client end is generally not required, ever. The amount of bandwidth dealt with doesn't require optimizations, but if you feel you need those few bytes/second on your consumer end NIC, be my guest.
