Problem with your speed connection?

Complete the most accurate test by clicking on "Begin Test." Speedtest. will automatically select the server with the lowest ping time. This means you will be connected to the closest server from a computer networking perspective. Speedtest.net provides hundreds of different servers located around the globe, thereby eliminating internet congestion that negatively impacts your speed test.

The "Begin Test" method is the most reliable, but feel free to experiment with manually choosing a server by selecting the white locator dots on the "Begin Test" map. You may also select a "Preferred Server" in your Settings to permanently give a selected server priority in any future tests. Due to Internet congestion and unpredictable ping times, you are usually better off letting Speedtest. select the best server for each test.

Test often and at different times of the day to ensure that your connection is up to speed! Utilize the My Results page to compare your Internet connection with others, and remember to use your test results when searching for solutions or settling disputes with your Internet service provider.

How it works

Start the speed test by clicking on the big button in the center of the page. The check will start by downloading a file and will measure your download speed. Once the download has finished, the broadband speed test will try to upload a file and will measure your upload speed
 If you want to get accurate results then you should not use your internet connection for any other applications once the speed checker is running.
Speed test is performed against the nearest of these servers - Ashburn (VA), Dallas/Fort Worth (TX), Los Angeles (CA), Miami (FL), Newark (NJ), Palo Alto (CA), Seattle (WA), St. Louis (MO)


What must be installed to use Broadband speed checker?

Speed checker should work in any web browser that supports Flash of version 8 and javascript.

Why the download or upload test does not work?

If you have a firewall or antivirus software installed that is not configured properly, then speed checker may not work correctly. Try to disable the firewall / antivirus when you are running the speed checker. After the test has been completed do not forget to turn it back on so you stay protected.

What does kbps mean?

It means kilobits per second. Usually, when you purchase a broadband then ISP explains speed in Mb. 1 Mb has 1024 kilobits.


What might affect my speed test?

Any applications running on your PC can affect the speed, so you should disable temporarily :

  • email checking software
  • instant messenger or other chat software
  • internet radio
  • windows updates
  • any other downloading

How does the speed checker work?

Our speed checker downloads a file from the server and measures how long your connection takes to download it. The size of the file will be different according to your line speed.

How accurate is the speed checker?

We have tried to build the speed checker as accurate as possible but there are several factors that can affect the test. The speed checker measures the speed at the time of the test so if your network is running slow at that time then speed checker will report a slow speed. This does not necessarily mean that your internet connection is slow at the other times.

How long it takes the speed checker to complete?

About 20 seconds.

Upload vs. Download

posted by Hanna

Upload vs. Download, what’s the difference?

For the average user, download throughput is the primary metric used when considering the speed of your broadband package to measure the quality of your online experience. Download throughput represents how quickly you can receive information, such as reading email, browsing web pages, downloading content such as music, photos or applications as well as the quality and buffer rate when streaming video.

Because download is more meaningful for popular activities, residential Internet packages are typically asynchronous, and normally download is much faster than upload. An example: 5.0Mbps/1.5Mbps package means 5 megabits of downstream per second, while only a fraction of the upstream at 1.5 megabits per second. Packages vary widely with some having upload as low as 128Kbp/s or just about twice as fast as a dial-up connection. In a future post we will provide suggested download and upload speeds for a variety of online activities.

Naturally, upload speeds are very important if you are hosting information via a web or email server. This is because the upload throughput will determine how quickly other users can access information from your network. Your upload is another person’s download and vice versa. Most residential users aren’t hosting servers, so in that respect upload is typically not a big issue.

However, where upload throughput really matters is when you want to quickly share outbound content from your connection. Examples of these activities include sending an email and uploading photos or video to a website like Facebook, Flickr or YouTube. As more users have a higher need to send large emails and post higher resolution photos and videos to websites, upload is telling a larger part of the whole story. Another increasingly popular use of upload is peer-to-peer (P2P) file sharing programs, such as BitTorrent, where upload is required to continually send content in order to have the privilege of downloading. VoIP, Video Conferencing and Online Gaming also require upload throughput for the bi-directional interactions.

So, depending on what you are looking to do with your broadband connection, be sure to consider upload speed carefully. Remember that although neither are particularly fast, even 256Kbp/s will allow you to upload twice as fast as 128Kbp/s and you’ll appreciate that the next time you upload pictures or send that big email attachment to a friend.

Improve your Internet speed

posted by Hanna

We believe that everyone should have free access to tools and information that help them get the best possible value from their Internet service. Our company has been working to ensure that the public gets faster, more high-quality Internet for years, and the goal of this post is to share that expertise with you. The power to optimize one’s Internet performance and increase overall satisfaction could be just a few simple steps away.

Remember: the overall quality and speed of an Internet connection is largely determined by the capabilities of your Internet Service Provider (ISP). However, there are questions you can ask – and answer! – to help ensure that you’re getting the most value from your connection.

To learn more about this topic, please read our full article “Improve your Internet speeds” in our Wiki.



What is Pingtest.net?

Use Pingtest.net to determine the quality of your broadband Internet connection. Streaming media, voice, video communications, and online gaming require more than just raw speed. Test your connection now to get your Pingtest.net rating and share the result


About the Line Quality Components:

Packet Loss

Much as it sounds, if you have anything less than complete success in transmitting and receiving "packets" of data then you are experiencing this problem with your Internet connection. It can mean much slower download and upload speeds, poor quality VoIP audio, pauses with streaming media and what seems like time warping in games -- your connection may even come to a total standstill! Packet loss is a metric where anything greater than 0% should cause concern.


This measurement tells how long it takes a "packet" of data to travel from your computer to a server on the Internet and back. Whenever you experience delayed responses in Internet applications - this would be due to a higher than desired ping. Similar to packet loss, lower is better when it comes to ping. A result below 100 ms should be expected from any decent broadband connection.


Once you understand ping, jitter should also make sense. Jitter is merely the variance in measuring successive ping tests. Zero jitter means the results were exactly the same every time, and anything above zero is the amount by which they varied. Like the other quality measurements, a lower jitter value is better. And while some jitter should be expected over the Internet, having it be a small fraction of the ping result is ideal.

How to use MSCONFIG in Windows XP and Vista

If you have ever had a tech support call regarding what programs start, when you boot up Windows XP, you may have heard the term MSCONFIG.  Perhaps you were instructed by a technician where to go and what to do with this tool.  Granted, this is not necessarily something that one would use on a daily basis.  However, there are occasions when MSCONFIG is quite useful, providing there is practical information on how to utilize it.

Before we get into what MSCONFIG is used for, we need to know how to access it.  This is accomplished by left-click on Start, then Run.  While in the Run dialog box, type in MSCONFIG (it is not case-sensitive) in white space, then left-click on Ok.  It is important to note, before proceeding, that any changes made in MSCONFIG require a reboot before they are permanent.



A medium-sized window will pop-up on your screen, with a selection of six tabs.  The first tab, which is selected by default, is the General tab.  Is this view, you will see three selectable radio buttons under the Startup Selection heading.  Normal Startup will be selected if you have never used MSCONFIG.  Diagnostic Startup will start Windows XP up in a “stripped down” functionality mode, akin to a Safe Mode startup.  If you choose this option, remember to change it back when you are done troubleshooting, or Windows will keep starting up in this manner.


If one does not encounter the Normal Startup being selected in MSCONFIG, they will see the Selective Startup having the dot next to it.  This means that something has been altered with Windows, and only the active items will start.  Not to panic though, it may have been as simple as a startup item being removed from its list.  Maybe the BOOT.INI file was modified to allow different boot option with Windows.

While I do not intend to get too deep into the nuts and bolts of the SYSTEM.INI, WIN.INI, and BOOT.INI tabs, I do want to show an example of what a typical BOOT.INI screen looks like.  In this screen shot, we see some standard boot commands with a Windows XP Professional setup on a single hard drive.


One of the reasons is that I would not want a computer user to venture boldly into the WIN and SYSTEM settings, is that any small change may cause Windows to break and sink faster than the Titanic.  I do not believe there is enough room in this post for all the documentation.  I recommend consulting your local computertechnician or the Microsoft Knowledgebase.

Oddly enough, the next tab over, Services, has a feature that I personally believe should be available in the other dangerous areas.  In the Services tab, you see all of your computer’s services relating to Windows, and any other program on your machine that is installed as a service.  The nice item in this screen is the Essential column heading (screen shot annotation #1).  This annotates that a listed service is necessary to run Windows.  Should you deselect it, well, it goes without saying that things, not necessarily good ones, will happen.


While in the Services tab, you can look at any non-Windows service by left-clicking on the Hide All Microsoft Services checkbox (screen shot annotation #2).  Doing this is not damaging to Windows, it is simply a toggle switch.  You can also Disable All (screen shot annotation #3) services if you want to, enough said.

The last tab in MSCONFIG is one of the more frequently visited areas.  The Startup tab controls what programs start with Windows.  If you want a program to not start alongside Windows, simply uncheck the box on the left-hand side of the window, under Startup Items, and it will not start with Windows.  Following the columns to the right, you will notice the program or command that runs with the start item, as well as the actual location in the Windows Registry where a reference is for that item.


There are exceptions to the MSCONFIG rule of stopping startup programs.  Various computer viruses, Trojans, and Spyware programs insert themselves into the Startup list, and are capable of self-repair.  If you uncheck a suspicious program from the Startup list, only to look at MSCONFIG after a reboot, and it is still checked, there is a possibility that you have a malicious program on your computer.

It is also possible that if you update certain programs, like Adobe Acrobat Reader, it will reinsert items into the startup list after updates are run.  However, as shown in the screen shot above, programs like Adobe are easy to spot on the Startup list.

Technical limitations/issues that can impact a customer’s Internet speed test results

Impacting Factors

 Speed Test Sites – there are a number of different sites available for testing the internet speed. Generally http://Speedtest.net is the one most accepted by general users and hosts. The user can choose different server sites on the speed test web site to perform the test although it will normally default to the one closer to the user. Traffic on the site, time of day, etc. can impact the results from test sites.

o Try performing the tests multiple times (waiting a few minutes between tests) from the same speed test site.
o Try another server location on the testing web site.
o Try another speed test web site.

 Customer CPE – the Operating System, make & model of the customer’s PC, software, VPN, spyware, viruses, firewalls, etc. can impact the speed results. For example, Microsoft XP has a known slow browse issue that can be helped by optimizing the registry. This is a common reason for these PC’s not obtaining maximum Internet services performance.

o Try other PC’s and verify if any speed differences (use same connection type – wired or wireless).

o Performing speed tests (customer) while the PC is in “safe mode” could provide improved speed results.

o Optimize devices with XP operating systems using the TUT Tool .

o Have customer confirm latest firmware or patch has been applied.

NOTE: for optimum functionality confirm PC is only connecting via one source, if wired turn wireless OFF and if wireless confirm PC is not connected via Ethernet.

 QoS– the QoS (Quality of Service) management function could impact Internet speed. The priority for QoS managing IP service is:
 #1 – VoIP,(voice over I.P.)
 #2 – Video followed by Internet, of these, video consumes the most bandwidth. The QoS functionality will assure enough bandwidth is available for VoIP no matter what other services are in use. Generally VoIP will have little or no impact to Internet service speeds unless active at the same time as video. The next highest priority is video, after VoIP,

QoS will then allocate bandwidth for video services. If any video is being recorded or any receiver is active the HSIA speeds could be impacted. Multiple PC’s connected to the internet could also impact the speed depending on what function they are performing (surfing vs. downloading for example).

o When performing speed tests verify all receivers are off (best if unplugged) and no recording is active (be sure to discuss with customer).

o Verify no other device is connected such as other PCs or smartphones.

 Wireless Mode – common modes for wireless connectivity are 802.11b, 802.11g, 802.11n and 802.11ac (called b, g, n, ac in future references). Most PC’s sold today have 802.11n or 802.11ac wireless capabilities but currently most homes have at least one device that is only 802.11g (or less) capable.

 Devices with ‘b’ wireless capabilities are limited to approximately 11mbps.
 Devices with ‘g’ capabilities support higher speeds, generally up to low to mid 20mbps and ‘n’ devices support our 45mbps service.
Generally our RG’s are set to b/g/n mode that allows a device with any of those capabilities to connect. The mode can be set to a multiple setting (b/g/n for example) or to a single specific mode.

NOTE: when the mode is on a specific setting (‘n’ only for example) devices that are not capable of that setting will not connect wirelessly. A good example would be Playstation3 which is not WPA2 compatible.

NOTE: speeds are limited not just by the wireless mode but by antenna as discussed later.
Wireless speeds for all connected devices can be impacted by the one device with the lowest wireless mode capability. For example, if the RG wireless mode is on b/g/n and a device that is only ‘b’ capable is wirelessly connected then all wireless devices will be limited to ‘b’ wireless levels even if ‘n’ capable.

NOTE: devices that are Wi-Fi capable such as a smart phone may connect wirelessly as soon as they are in range (if they are configured for that RG). If the mode of that device is the lowest capable mode, then when it comes into range and connects it could impact the wireless ability of higher capable devices.

NOTE: setting the mode to ‘n’ only in most cases will automatically change the security setting to WPA2.
o Verify wireless mode, if device is ‘n’ capable turn mode to ‘n only’ for testing (be sure to move back to b/g/n when finished).

 Security Settings – RG’s generally have several options for security settings, the default is normally set to WPA/WPA2 (both). WEP is used by PC’s with older operating systems and provides the least amount of security and slower speeds. WPA provides better security and speeds. WPA2 provides the best security, is the optimum setting for 802.11n capable devices and is required for ‘n’ capable devices to reach their speed potential. By having the default on WPA/WPA2 it allows any PC with either of those capabilities to connect.

NOTE: Setting the security to ‘WPA2 only’ will only allow devices that are WPA2 capable to connect. Generally 802.11n or 802.11ac are the only devices that are WPA2 compatible, WPA allows non-802.11n devices to connect which could impact wireless speeds for ‘n’ or ‘ac’ devices. If testing in ‘WPA2 only’ make sure to return security setting to WPA/WPA2 if that was original setting.

 Wireless Channels - during the initial boot up the RG will generally perform a wireless auto channel selection based on the number of wireless devices it identifies on each channel. This automatic selection will choose the best option for wireless connectivity. The channel can also be selected manually within the GUI. Channels 1, 6 or 11 normally offer the best choice for wireless connections but would depend on settings of other devices within range.
o If there are several wireless devices within range and the RG has the option to scan for new channels perform a scan for the optimum channel.

 Inside Wiring – the recommended home run (wire from NID to RG) is CAT5. For customers with higher HSIA speeds it is required to have CAT5 home run. All home runs should pass all required testing.
o When running wired speed test, connect PC directly to RG.

 Antenna – along with the wireless standard on the device you may see something like 802.11n 1x1 or 802.11n 2x2 for instance. The 1x1 designation is the antenna configuration and is the number of transmit and receive radio chains built into that device. 2x2 implies it can support 2 “spatial streams” which will assist the device in supporting faster speeds than the 1x1 configuration. Newer devices are now coming with 3x3 and even 4x4 that can support much higher speeds. You will see some designations such as 2x2:2 or 3x3:3, this is a notation showing TxR:S where T=transmit radio chains, R=receive radio chains and S=”spatial streams”. In some cases a 2x2 configuration does not actually support 2 “spatial streams” so it will not support the same speeds as a true 2x2:2. The 2x2:2 signify it supports MIMO (pronounced “My-moh”) which stands for “Multiple Inputs, Multiple outputs” and allows for obtaining optimum wireless speeds. The

antenna configuration can have an impact on how or if the device can obtain the higher HSIA speeds. As with most wireless devices, distance from the AP, obstacles and interference will impact the ability of the device to perform at the optimum level no matter what antenna configuration the device has.

 Bandwidth – most RG’s provide a choice of either 20MHz or 40MHz, the default should be set to 20MHz. In most circumstances this is the best choice for optimum performance particularly if in a location with crowded wireless usage (MDU for example).

 Browser – changing browsers (Chrome to IE for example) could provide varying speed tests results.
o If available try running the speed test on another browser, run test multiple times.

 Location of Devices – ‘n’ capable devices will have better range than ‘b’ or ‘g’ devices but walls, flooring (in multiple floor locations) and other obstacles will impact wireless speeds.

o The RG should be located away from any electrical or motorized interferers (speakers, water pumps, electrical motors, etc. for example).
o Verify the power supply is at least 6” away from the RG.
o RG should not be contained in a closet or cabinet.
o RG should not be within close proximity to a cordless phone base or microwave.
o RG should be standing vertically with nothing on or against it.
o RG should be away from large metal objects such as metal racks or cabinets.

 Wireless Power Level/Setting – power setting should be defaulted to 100% which is the optimum setting for most locations.
o If the customer does not have multiple wireless routers the setting should be 100%.
