Internet Speed Test - Broadband, DSL Bandwidth Connection Check. This internet speed test can be used to help you determine your true bandwidth on any connection, such as Broadband, Cable, Satellite and DSL Modems. Note: For best results, please make sure you are running the latest version of java. NOTE: IF you can’t run the speed test or the load it too high (connection refused message) try my Facebook Speedtest Application. If you have any questions, please leave a comment at the bottom of this page. We created our Internet Speed Test to be the most accurate broadband Speed Test on the internet! In fact, many sites charge for speed tests similar to this one! Because this speed test is so popular we have to limit the test to 1. Although we have a large amount of bandwidth, this speedtest may take up to 3. Think the test on this page was cool, then check out our new Broadband Speed Test! You can put place the test on your site free of charge, complete with logging options and much more! Before you start the Speed Test, please keep in mind that it uses TCP port 8. What does this mean? The higher QOS percentage, the higher the overall quality of the internet connection. The faster (smaller) the RTT, the better broadband speed you’ll have. For Voice over IP, round trip delays can occur when results exceed 2. Sec or 1. 50 m. Sec one way which is also considered the maximum desired one- way latency to achieve high- quality voice. Max Pause. Max Pause is the longest pause recorded during the Broadband Speed Test data download. This should be a very small number. If not, it could indicate Internet speed congestion or a bad broadband connection. Anything less that 1. Speed Test – How It Works. Existing Internet Speed Tests – bandwidth testing techniques are not suitable because link asymmetry and ATM traffic shaping in x. DSL deployments impact the accuracy of their speed test measurements. Speed Test – Techniques. A number of techniques exist for Speed Test and bandwidth measurement. Most of them can be categorized into two groups. One group is a variant of pathchar based on the one- packet model. The disadvantage of this group is heavy overhead in bandwidth consumption. The other is a variant of packet- pair based on the packet- pair model. This group imposes lower overhead compared to the first group. In theory, one- or two- packet techniques and the tailgating technique in internet speed tests and can get good estimation of x. DSL link bandwidth. However, the existing tools do not regulate the probe packets so that ATM traffic shaper will regulate the probe packets for them by packet delay or packet drop. One possible solution is that to explicitly regulate the probe traffic, but then it is difficult to specify the source rate for speed tests. That is why a stepwise scheme is proposed: in the first step of the bandwidth test, a rough estimate of the bandwidth is obtained and the subsequent probe traffic is regulated according to the estimation. Multi- packet technique is used to avoid explicit packet filtering to help accurately measure internet speed. Broadband Tests – Traffic Shaping. Our broadband speed test take into account that ATM traffic shaping has a goal of regulating the traffic flow as per the parameters describing the negotiated Qo. S to achieve better network efficiency. The basic idea of ATM traffic shaping is buffering the packets/cells and controlling, mostly delaying, their entry into the network, thereby ensuring a more constant flow of traffic in the network. DSL Speed Test – Application to Asymmetric DSL Networks. The DSL Speed Test understands that the asymmetric nature of ADSL networks makes it necessary to have different measurements methodologies for upstream and downstream cases. I worked on a project with a MS SQL server 2008 containing data of NVARCHAR type in multiple languages, including asian characters. It is a known issue, that the PHP. Ping is built into Windows and tests whether you can reach a particular. Error 651 is a well-known bug in Windows 8/7 which happen when you try to connect to the Internet using PPPoE connection. If you are also a victim to the E. After installing Windows Server 2003, Windows Server 2008 and Windows Vista into Microsoft Virtual PC’s virtual machine (VM) (update to Virtual PC 2007 SP1) as. Does your laptop keep dropping or losing its wireless connection for no reason? Or maybe your laptop can see the wireless access point, but won’t connect unless you. Probing traffic with the slightly higher rate (e. A server process on the Bandwidth Measurement Server, echoes back the packets as they arrive at the server end. The time difference, T, is measured between the arrival of the first packet and the last packet at the client end. During the broadband speed test, the upstream bottleneck link bandwidth, b. Nx. Px. 8)/T . A receiving process at the client measures the arrival time of the packets. Because of the nature of ADSL, such that the upstream bandwidth is smaller than the downstream bandwidth, the client does not echo the probe packets back. Instead, the client computes the downstream bandwidth to accurately check internet speed. Bandwidth Speed Test – Stepwise Scheme. The stepwise scheme consists of at least two steps during the speed test. It can be used for both downstream and upstream bandwidth measurements described in the previous section. The generated traffic should be smooth rather than bursty to avoid excessive ATM traffic shaping. The stepwise bandwidth measurement scheme runs several times and reports the maximum measured value as the link bandwidth. During the first bandwidth measurement step, a small number of packets, e. This small number of packets will likely not be affected by ATM traffic shaping, as most ATM networks are capable of handling such small bursts. The computed result is used in the second step of the speed test as the trial bandwidth of the x. DSL link. The subsequent step(s) in our internet speed test assumes that the accurate x. DSL bandwidth is close to the trial result obtained from the first step. A larger number of packets than that in the first step are used in the measurement to ensure that the results are convergent and in the end consistent. Had it not been for the first step that approximately determined the bandwidth, the sustained higher- than- provisioned traffic would result in a considerable loss or queuing delay caused by ATM traffic shaping, and this would end up providing inaccurate internet speed test results. Is it Megabits or Mega. Bytes? Q) Is Mbps in the speed test graphic referring to “mega bits per second” or “mega bytes per second”? A) It’s mega bits per second. A byte is a measurement of size while bps is a measure of speed such as sending something across the internet. An uppercase B always stands for “bytes” while a lowercase “b” always stands for “bits per second”. Kbps is spoken as Kilobits, equals 1,0. Kb or Kbits. Mbps is spoken as Megabits, equals 1 million (1,0. Mb or Mbits. Gbps is spoken as Gigabits, equals 1 billion (1,0. Gb or Gbits. Internet Speed Test – Conclusion. In Summary, we have put a lot of time into designing the most accurate and easy to use speed test on the internet, and for free! I should also mention that these sites have been designed around our free speed tests. Need help with the speedtest? Questions, comments or concerns about our internet speed test? Troubleshoot Windows XP Wireless Network Connection Problems. Does your laptop keep dropping or losing its wireless connection for no reason? Or maybe your laptop can see the wireless access point, but won’t connect unless you restart the entire computer? These are some of the problems that I’ve had myself and so here is a quick and dirty guide to troubleshooting your wireless network in Windows XP without having to go out and buy a new router! I also wrote a more recent post on troubleshooting Wi- Fi problems in Windows 8. Firstly, the more common wireless issue is when the computer will continuously drop from the Wi- Fi network and then suddenly reconnect for no apparent reason. The main culprit behind this type of problem is usually software, not hardware. By software, I don’t mean your Windows operating system, but the device drivers for your wireless network card and your wireless router. You’ll need to visit the web site for the hardware manufacturer for your PC and download the latest drivers. So if you have a Dell, go to support. Same thing applies to your router, go to D- Link, Netgear, or the Linksys web site and install the latest firmware for the router. You can read a previous article I had written about updating drivers for your wireless card if the connection is dropping. That will usually fix any problems with the connection being dropped! If you’re having problems connecting in the first place, you might want to try resetting the current configuration in Windows and then try to connect. You can do this by first going to the Control Panel and clicking on Network Connections. You’ll get a list of all the current connections on your computer, such as bluetooth, wireless, local area connection, etc. Go ahead and right- click on your wireless network connection and choose Properties. Click on the Wireless Networks tab and click on the name of the network in the list of Preferred networks. Now you want to click Remove so that Windows will erase any of the current settings for that network and will start from scratch. A lot of times when you refresh the list of networks again, Windows will automatically connect. Go ahead and click OK and then click on the wireless network icon in your Taskbar and try to connect again. If that does not work, you can also try to Repair the wireless connection. The Repair option tries a few other things, such as disabling and re- enabling the wireless card, clearing out the DNS cache of old records, and then connecting to the wireless network. You can do a repair by going to Network Connections as shown below and right- clicking the wireless connection and choosing Repair. My image is showing Local Area Connection, but you should see Wireless Network Connection if your computer has a wireless card. Finally, it’s a good idea to check the TCP/IP properties of your network connection to make sure they are configured properly. A lot of times people manually change them or are told to change them by computer help desk folks on customer support calls. To check the settings, go to Network Connections like mentioned above and then right- click on the network connection and choose Properties. Now select Internet Protocol (TCP/IP) in the list box and click on Properties. You’ll want to make sure that the Obtain an IP address automatically and Obtain DNS server address automatically radio buttons are selected. There are cases where the IP address and DNS server addresses have to be manually entered, but that is rare and should never be the case in the home environment. So if updating the driver, resetting the configuration, and repairing the network connection don’t work, then try to unplug the wireless router and plug it back in after about a minute. It’s best to turn off the cable modem too, but you should always turn on the modem first, then the router. Unless there is something physically wrong with the router, one of the methods above should work! If you’re still have trouble with a network connection in Windows XP, post a comment and we’ll try to help.
