Q. What can I do about Dropouts?
We have a number of suggestions that you might like to try to reduce these problems.- Before you even turn on your computer.Call WaitingEnsure that you have disabled call waiting. When some one calls you and you are already on the internet, the beeps that you would normally hear if you were on a voice call are sufficient to disconnect your modem. To turn call waiting off dial #43#, before you use your modem. You should hear a voice confirming that call waiting has been disabled. To re-enable call waiting dial *43#. You can disable call waiting for the duration of your Internet connection by adjusting the dialup number to :
*44 0198 333 550
It is recommend that your modem be plugged directly into the phone socket. Telephone extension cords and telephone adapters may interfere with the connection, which can result in disconnections. We also recommend that if having dropout problems to remove any other device from the phone line, even if you are not using the device it can interfere. This includes telephones, answering machines, faxes and back to base security alarms. Many of these devices generate noise or draw power from phone lines, which is sufficient to interfere with a modem call.
It is also good to make sure your modem is placed in the best location on your desk. Oviously this can't be done with an internal modem, but try to place your modem in a clear space, where is can be kept cool. Try not to use your modem as a shelf, stacking papers and books on your modem will cause it to overheat, and this can cause damage to your modem and also cause a dropout.
- Now its time to turn on your computer
Hopefully that will have helped but if you continue to have problems, you might like to try a modem initialisation string. This is basically an instruction for your modem in the form of combinations of characters which each tell your modem what to do. For Rockwell Chipset based modems (i.e. most generic modems) we suggest you try this string: AT&FW2&C1&D2&K3%c0
For other modems try modemhelp.net, modemsite.com, or consult your modem's manual.
The next thing to do is try and establish whether there are actually problems with line noise. In some cases you can do this yourself as you can hear the noise when you are on the phone talking to people.
As an aside Ascend are the people that make our fully digital terminal servers that your modems dial in to, when you call Chariot. Between our digital Ascend Maxen and out fully digital fibre optic lines in and out, we can be positive that drop outs are usually (98% of the time) not at our end.
The next step in line testing we would suggest is to ask Telstra to check your lines. Just because they checked out OK to your ears, does not mean they are noise free. Modems are far more sensitive than human ears. To do this dial 132203 and a Telstra operator should be able to test your line. Be aware however that a successful test does not mean the line is noise free. Telstra only test for voice quality and very low data quality. In fact Telstra only guarantees that you can obtain speeds of 2400 bits per second on a normal line (Telstra Quick Tips for Reliable Internet Access). This is between 10 and 25 times slower than the average modem on today's desktop. Telstra has recently standardised procedures and increased operator awareness for modem related problems such as drop outs and similar Internet connectivity problems, so your Telstra operator should hopefuly be more helpful than some people have experienced in the past.
If your line checks out okay, and none of our other suggestions have helped, then you might try lowering your modem speed. Typically the slower the connection speed, the more reliable the connection will be. To lower your modem speed go to the Extra Settings box in your Modem Control Panel (as per the above instructions) and add the following string: The following is for 33.6K or slower modems.
This will prevent your modem connecting at speeds faster than the last number in the string.
You can then reduce or increase the last number of the string until you get a number that works for you. You can only use the following numbers as the last number: 33600 28800 24000 19200.
For K56 Flex
or For V90 modems you should use this string
and try stepping up or down the speed in the following increments (replacing the last number with these):
54000, 50000, 46000, 42000, 38000, 34000, 33600, 28800, 24000, 19200.
Following these instructions will reduce your connection speed, but should increase your reliability.
