You can also achieve a similar effect if you limit the upload speed to a value below your allocated upload bandwidth.

There are paid software solutions for this.
To solve this problem, you'll need some kind of priority system to make sure the ACK packets are not throttled.
This delay can happen on any packet including the delay-sensitive ACK packets. Your ISP (or your network device) controls your bandwidth use by delaying packets when your transmission speed exceeds the limit (aka throttling). So it requires frequent ACK messages to be send in the uplink for your download traffic to go through smoothly If the ACK messages are delayed or lost, the sender may slow down transmission and/or retransmit packets that you have already received.īy default, packets are transmitted by the OS in the order they are generated by the applications, so the ACK packets are interleaved with your upload traffic randomly. This means it will only send new contents (slide the window) when it receives the ACK messages indicating that part or whole of the current window has been received completely. The TCP protocol, which most Internet traffic uses, uses a "sliding window" scheme to provide reliability. Having a good internet service will allow you to upload. Perhaps there is something I can do it fix it without spending another hour rebooting my modem while I am talking to an inept support person. The CenturyLink speed test will provide you feature tool and will check the speed of your internet. So my question is if this behavior is typical of CenturyLink DSL or if something is really screwed up. Upload speed impacts how quickly you can send data from your devices through your network to another device or site on the internet.

The test results give you a full picture of your internet connection. Finally they sent me a new (refurbished) modem to get me off the phone. The internet speed test includes both upload and download speeds, so you dont have to test upload speed separately. They had me reboot my computer and modem a few times, which of course didn't help. I called CenturyLink's support and talked to them for an hour and they said everything is fine. For example, pinging Google takes 5 seconds to resolve the DNS and then the requests time out. But as long as one computer is uploading, all the computers might as well be kicked off the internet. The networking between other computers in the house is fine. It is so bad I cannot even connect to to do a speed test. The upload takes forever, which I understand because of the 893 Kbps upload speed, but the entire time it is uploading the download speed grinds to a halt. I've ran speed test and it typically reports speeds close to that.Įxcept whenever I upload something substantial. Truthfully, do you want to know how fast your connection is within your providers network or do you want to know how fast it is to the locations where the websites you visit are being hosted? is not a best case scenario connection test and will test your Internet under real world conditions.I have the 20,127/893 Kbps service through CenturyLink DSL. This can make your connection appear faster than it really is. Other speed tests, especially tests offered by your Internet provider try to eliminate routing factors.

This test is unbiased, it tests and grades all providers on the same criteria. When providers host their own speed tests they eliminate the variables that you're here to test. A third party opinion is necessary and the provider shouldn't be allowed anywhere near the process. We believe that it's a conflict of interest when Internet service providers operate their own speed tests.
