Internet Tools

29 Nov 2007

 

Internet Tools is a collection of three utilities that will assist ypu with troubleshooting internet connection issues. In most every instance one of these five tools should help you isolate the problem and provide the evidence to your Internet Service Provider (ISP). When Internet Tools first opens it will check for any updates then take you to the main screen. From there you may select the test to run or find answers to many of the questions you may have. You will also need to enter your Internet Rated Speed, in Kb. If it is unknown, enter 512.

Internet Tools should be run before having problems, allowing you to obtain pings and traces to your favorite sites, especially for gamers, then save this data for comparison when problems arise. One thing providerís do on a regular bases is to look establish new peer agreements with different companies who will be carrying data from their network to others. When they make these changes you will usually know it with changes in pings and possible performance. If prior traces have been established, you can show your providers how the changes have affected you and possibly invoke a change.

 

Ping Tester

The first component of Net Tools is the ping tester. Ping Test is designed to ping up to five separate locations and provide the Low, High, and OverAll Pings along with any detected packet loss. You can change any or all of the five URL sites to those of your choosing. They may also be the IP verses the URL. (Fig 2)

As with all three of the utilities you will be able to save the data to a file or copy the information to the clip board, which may then be pasted in any document or email. Here is an example of the saved/copied information:

Trace Route

Trace Route is designed to show you each hop between your computer and the site you are connecting to. Trace Route will also show you the ping along with any packet loss at each hop. You may enter up to five sites and set the number of test to run to each (Fig 3).

Trace Route Test (Fig 3)

 

When complete you will be able to analyze each hop and determine which one may be causing your problem. It is always good to run one trace route test to common sites you visit, when you are not having a problem, and save the data as a baseline to compare to when problems occur. Here is a sample trace route:

InDepth Internet Analysis

This is the third tool available for you to help isolate internet issues. It is quite unique and will provide a very detail report of each hop between you and the site you are testing to (Fig 4). As it does provide a very detail report, it will also take longer to complete, with the OverAll test lasting 8 to 10 minutes.

When you move your mouse over the options available, you will receive a detailed description in the lower test window. Like the other two, you will be able to copy or save the information collected. Here is a sample test:

 

This provides detailed information on internet latency and loss

This test can take up to 10 minutes or longer depending on total hops and queries

Port Activity

The Port Activity function of internet tools will show you all port activity for TCPIP and UDP. Along with showing you the active port, it may also show you the IP connecting to/from long with the process that is involved with the activity. This can be an excellent tool in identifying spy/ad ware.

Stability Test

The Stability Test will examine each of the hops to your selected destination point. It will run 100 tests to each Hop and graph the results along with providing a list of the test results in the information window. This will allow you to see any hop that may be erratic and report it to the host.

Download Stability Test

The Download Stability test comes in two parts, the first is to measure each packet received and compare each one for those above and below average. This will then be reflected in the overall stability of the connection to the source. The second part is to examine and graph the actual download performance. Files are download in different sizes and from different locations giving you a true reflection of your performance. It is recommended that you do one or two test initially, then only when there is an issue and you desire to verify performance, as this test is intense and can overload and disable the network card. The results are saved in the internet tools folder under Download Stability Test.txt. Also note that faster speeds, for example 10,000 Kbps may yield a lower stability test as they force as many packets as possible as fast as they can.

MTU Tester

 

The MTU is an additional utility added to allow you to set your Maximum Transmission Unit (MTU). Windows XP comes with this value set low and by setting it to its optimal setting, you may get better performance when downloading files. When you download a file, it is broken into many packets of data before it is sent over the World Wide Web to your computer (where it is then reassembled). The size of these packets is called your MTU value. Setting your computer's MTU value too low would make downloading less efficient because a greater percentage of the packet is taken up by the packet header which contains a variety of information about the packet, source, and destination. However, setting the MTU too high can also decrease efficiency. Other computers on the Internet might not be able to handle MTU values of a certain size. If you set your computer's MTU value too high, some computers along the delivery path would be required to break these packets into smaller pieces before accepting them and passing them to the next computer. This "Stop. Break. Go." processing of packets can dramatically slow down data transfers. For Ethernet, the MTU is 1500 bytes, for PPPoE 1492, dial-up connections often use 576. XP often limits this even more.

 

This test comes in three parts. First is to select the test source. For most applications, yahoo.com will be ideal; however, if there is a site you frequent the most, you can select it.

 

mtu1

 

Next a series of 50 ping test will be accomplished to ensure; 1. the ISP is operating well enough to set this value, 2. the source is stable, 3. all hops along the route are stable.

 

mtu2

 

Then will come the test which will examine the route through all of the possible MTU settings, finding the largest one that works without issues, then setting your system to this value.

 

mtu3
