I will try to be clear as i can.

Firstable my english is not good so I hope that u guys can understand me.. The thing is, I tested my connection with the ICSI Netayzr and then it shows that I have High Network Buffering (Network buffer measurements: Uplink 490 ms, Downlink 2000 ms) so I started to read all kind of posts and everything, then i discovered this page and it seems to be very helpfull... I downloaded the TCPOptimazer and with the help of threads I tried to change all the values, but it doesnt work.. I became so mad and changed all the values in excessive way, trying to get at least some light with the functionality, Nothing happens... Im very sad because I think that I will never get a good internet performace, the one that i need ( particularly for games as "League of legends", for example ) I hope that u guys can help me...:(

I share my results of Sppedguide TCP and Speed

Hi,

I have a 2 Mb internet ADSL line and when i use it for downloading files by applications such as IDM or other download accelerators which use more than one connection i have the speed of 250 kilobytes per second but when i download the same file through IE or other browsers which use single connection i have speed of 40 to 60 Kilobytes per second, up to this point there isn't an issue as i can use download apps but when i want to use my slingbox in order to watch a video stream which use a single connection my problem begins that i don't have a good and stable speed and i can't use my bandwidth full potential, so i was wondering is there an application or any other free or paid services which could do the IDM scheme in making numerous connections for single connections such as Slingbox?

I should point out that there is a slingbox connected somewhere and i want to watch it and i have downloading speed problem. I have a ADSL line with up to 4 MB downloading speed with more than 200 kilobytes per sec solid downloading speed. in summery i can say that i'm looking for a way to use my full bandwidth potential ( as IDM does in downloading files ) in watching slingbox stream that i'm receiving.

I have used a service called Globax in the past months which use a scheme in getting full bandwidth potential on any single connection as IDM does in downloading files but recently as this service was working on UDP port which my isp and other ISPs based on authorities decision has put limitations therefore it doesn't work anymore and i'm looking for such service.

An important note :

Hi I ran the ICSI Netalyzer test 2 times today and got this message :

Network buffer measurements (?): Uplink 620 ms, Downlink 50 ms –


We estimate your uplink as having 620 ms of buffering. This level can in some situations prove somewhat high, and you may experience degraded performance when performing interactive tasks such as web-surfing while simultaneously conducting large uploads. Real-time applications, such as games or audio chat, may also work poorly when conducting large uploads at the same time.

We were not able to produce enough traffic to load the downlink buffer, or the downlink buffer is particularly small. You probably have excellent behavior when downloading files and attempting to do other tasks.

Second test was at 1000ms and categorized as red color
