________________________________________________________

Open up your internet browser and go  https://oxfordtutorials.webex.com/
Use the password which I sent you at the time of registration.
Click on the link to join your scheduled class.
Type in your name (first and last name are required)
Type in your email address
Use the password which I will send you following registration.
Follow the instructions if WebEx prompts you:
1. to click on the Information Bar;
2. for permission to install something (like "Active X");
3. to run an Audio Test, etc.
  Be sure to give the program the correct and current information about your system e.g. whether or not you use a PC or a Mac or a laptop and whether or not you use headphones; WebEx will make adjustments to accommodate your computer) When you enter the classroom decline the prompt to "join the conference: until you first run the Audio Setup.  Go to the menu bar in the top left-hand corner and select "Communicate/Audio Setup Wizard;" Follow the instructions as you are prompted.
_______________________________________

NOT TO WORRY!  IT MAY TAKE A BIT...
You should be able to hear someone speaking within a minute or two of logging on (don't panic if you don't hear anything right away).  It takes a little while for the sound system to engage.  You will only be able to use your microphone when the microphone is "passed" to you by the Host or the Presenter (usually the tutor).  There may be a window that says: "Preparing Internet phone..." and on slower computers it may take up to 20 to 30 minutes to finish down-loading.  However, you should only have to do that periodically (the first time you use WebEx and after new updates).
_____________________________________

YOU MIGHT NEED TO USE THE CONTROL KEY:
If you don't have a headset, or if the sound isn't transmitting, then you may need to hold down the "Control" key (bottom left-hand corner and/or bottom right-hand corner of your keyboard) when you are speaking.

YOU MIGHT NEED TO RECONNECT/START OVER:
If you can't get audio or lose audio then you might have to start the process over (leave the room and return). 

YOU MIGHT NEED TO UPDATE YOUR BROWSER:
WebEx supports most browsers, but make sure that you are using the most recent version of your browser.  Older browsers can cause problems with the audio transmission.

PROBLEM WITH SLOW COMPUTER CONNECTIONS: 
Check to make sure that you have a stable bandwidth during the session. You can check if you have the desired bandwidth by following these steps:

1. Go to the website http://www.pcpitstop.com/internet/default.asp
2. Click Measure Download Speed.
3. Click Run Bandwidth Test. An image will be loaded on the browser to test
the connection speed.
4. Wait for the test results until the image gets fully loaded on the browser.
5. Please ensure that the download speed is more than 256 kilobits per second. If it is below 256 kilobits per second you may have to contact your IT department to test the internet connection.

Don't forget to use the Audio Setup wizard available on the "Communicate" menu to properly set up the VoIP.


YOU CAN CALL TECH SUPPORT 24/7:
If you continue to have trouble there is a WebEx Tech Support center which you can call for help.
The number is: 866-229-3239.   They will want to know the WebEx address for our classroom:

CHECK LIST FOR SOUND TROUBLE:

1. Run the Audio Set-up Wizard (Instructions below)
2. Make sure mic and speakers are plugged in
3. Make sure mic and speakers are not muted
4. If you can't hear anything, check the volume control for your speaker;
    make sure the volume is turned up (move the slider on the bar to the right)
5. If others can't hear you, check the volume control for your microphone;
    make sure the volume is turned up (move the slider on the bar to the right)
6. IF NO ONE HEARS YOU, TRY HOLDING DOWN THE CONTROL
    KEY. IF ONE DOESN'T WORK, TRY THE OTHER. (FOR SOME
    STUDENTS, THE CONTROL KEY ON THE RIGHT SEEMS TO
    WORK THE BEST.  ONE STUDENT GETS HER BEST SOUND BY
    PRESSING DOWN BOTH CONTROL KEYS AT THE SAME TIME.
7. Try exiting and reconnecting
8. Make sure that you are using an updated version of your internet browser
    (Internet Explorer, Firefox, Netscape, Safari, etc.)
9. Test to see if your sound equipment is working by using the Sound Recorder
    which is built into your computer.  In Windows go to: Start/Programs/
    Accessories/Entertainment/Sound Recorder and try recording a short sound
    clip by speaking into your microphone.  Then try playing it back again.  If you
    can't get any sound you may need a new microphone, speakers, or sound card.
10. IF YOU STILL HAVE TROUBLE: Call WebEx TECH SUPPORT at:
      866-229-3239. They will want to know which website you are using.

Steps to improve computer speed and efficiency

1. Reboot (shut-down and re-start) your computer at least once a week.  If you don't your Operating System will have a tendency to get bogged down with clutter and run less efficiently.   

2. Take steps to reduce clutter.  One of the things that can slow down your system is unseen clutter.  If you have one of the new Windows Operating Systems like XP, there are two programs which you should run at least once a month.  The first is called "Disk Cleanup."  The other is "Disk Defragmenter."  You can find them by going to Programs/Accessories/System Tools.   

       (1) Disk Cleanup
       (2) Disk Defragmenter 

The first will delete unnecessary and unused files (mostly "Temp" files).  The other will rearrange the data on your harddrive to run more efficiently.  You can find both programs by going to Start/Programs/Accessories/System Tools/Disk Cleanup & Disk Defragmenter.

In addition to those programs I also regularly use two other free programs to detect and delete hidden clutter.  Both of them can be found at the following website: down which www.download.com   The two programs are: (1) Adaware; and (2) Spybot.  Go to the download.com website and look under "MOST POPULAR."  These links should direct you to the most current, updated versions now available:   

 (1) 
Ad-Aware SE Personal Edition
 (2) 
Spybot - Search & Destroy

These four maintenance programs can make a huge difference in the speed and efficiency of your computer. 

3. Check your connection speed.  Audio problems are worst when your connection speed is not fast enough.  Try to obtain a connection speed of at least 36K.  If you can't get 36-40 K, consider switching ISPs (if you have an option).  You can use one these free links to see how well your connection is working and what your connection speed is right now:

     http://bandwidthplace.com/speedtest/  
     http://www.broadbandreports.com/stest
     http://www.dslreports.com/speedtests/  
     http://toast.net/performance/

   
4. Make sure there are no unnecessary programs running in the background on your computer.  Other programs (like Instant Messenger) can suck up resources and cause interference with the audio in our classroom.   Hold down these three buttons on your keyboard at the same time: "Ctrl," "Alt," and "Delete."  When you do that you should see a screen pop up which says "Windows Task Manager."  If there are programs running there which you aren't using, go ahead and click "End Task."  It will free up more space for Netmeeting. 


Steps to check and improve audio quality

1. If you are using a Dial-up modem go to My Computer|Dial-up networking, right click on your ISP and select Properties|Configure and make your maximum modem connection rate 38400.


2. If you find that you are not able to get your audio to work you might have a problem in your mic or sound card.  The best way to trouble shoot your audio problems is to see if you can record and play back sound using the sound recorder.  You can find the recorder at Start|Programs|Accessories|Multimedia (or Entertainment)|Sound Recorder.  If you can not record and playback sound with the sound recorder, your problems are not with Netmeeting but your mic or soundcard.  Your mic should be in the "Mic in" hole on your sound card.


3. Here is a tip from Mr. Hinrichs if you would like to test the quality of your Internet connection to the ETS reflector which hosts our classroom(s). If you do not have a good connection, it is very likely that you will have trouble connecting to the reflector, will often get knocked off and will have poor audio.

To test your connection, go to start|run and type "ping -t 207.158.2.221".  If you receive the message "request timed out" your connection might produce poor audio quality.  This message occurs when information is lost or dropped.

This test will result in you being given four ping readings. These readings simply tell you how many milliseconds (ms) it takes for your connection to reach the ETS server. Being just a few miles away from the server, it takes Mr. Hinrichs' connection about 35 ms. His 33.6 modem takes about 150 ms. Up here in Seattle my connection speed is around 65 ms.  If you have a connection that gets a ping of under 400ms, your system should work very dependably. Anything under 600ms is acceptable. Over 600ms you will start to run into trouble and should consider changing ISPs. Before you sign up with an ISP, it would be good just to call them and ask them to ping gbt.org. They can run this test very easily and should be able to give you a value over the phone.

If you are having trouble with your ping rate and would like to diagnos where the problem is, you can use the traceroute application in the WS ping pro pack at http://www.ipswitch.com/Products/WS_Ping/index.html.   To run a continuous test on your machine to see when your connection is dropping out, do the following with Ping Pro.  Run WS Ping ProPack.  Select the ping tab.  Insert 20000 in count.  Insert www.gbt.org in ip address and hit start.  If your connection goes bad, you will see time out messages appear.

If you would like to have more information than a ping test gives you, perform a trace route.  Here is how.  Open you Internet connection and then open a DOS window. To do this under Windows go to Start|run and type, "tracert  207.158.2.221."    The trace route will show you the specific hops on the Internet that your connection has to go through.

4. Visit a trouble-shooting website for help in focusing in our your particular problem.  For example, there is a Microsoft website at the following link: http://www.microsoft.com/windows/NetMeeting/Corp/reskit/appendixb/default.asp#setup 

        "Rejoice always, pray constantly, give thanks in all circumstances.   For this is the will of God in Christ Jesus for you."  1 Thess. 5:16-18

**  Because of increasing difficulties the ETS affiliates stopped using CUSeeMe in 2003 and switched from Netmeeting to WebEx in the fall of 2007.  We now use WebEx, a browser-based system which is easier to use and more dependable than the previous programs.
