Dynex m300 modem problems on xp

How do I list them? let me count the ways!! Well, it will simple disconnect, that is easy to fix. Sometimes it will simple stop and never responding till the computer is reboot. Other times it will disconnect and respond with an error message stating that a modem already has the resources. this one is nasty; if you remove the usb cable the cumpter will jump to the blue screen of death. On boot up it may or may not find the modem and I then must perform a xp restore function, other than that it works ok :)

Re: dynex m300 modem problems on xp

Rich, Below is the link for the newset drivers for you modem. Make sure your machine is up to date with microsoft. Have you checked for viruses and spyware? Is the machine running hot? It is sounding flakey(like a bad unit). You should not have to do a system restore because of a modem unless it just really "hosed" your system and if that was the case,then that would be the last time I would use that modem. Let me know what happens Good Luck, Tim

Reset the modem by removing the power cable from the back of the modem for a full 30 seconds and plugging it back in.

This is sometimes referred to as "power cycling" the modem, and is a good way of clearing network timeouts and other problems that can appear on modems that have been running continuously for some time.

Reset the modem by unplugging the power cord from the electrical outlet or surge protector into which it is plugged.

This is a good alternative to removing the power cord from the back of the modem if it is difficult to get to the modem because of its physical location. Count the full 30 seconds and plug the modem back in to complete the reset.

Reset the modem by pressing the reset button the back of the modem.

The button itself is recessed into a hole to prevent accidental resetting, so you will need a pen or some similar thin utensil that can fit inside the hole.

Press the pen into the hole until you feel the button depress and then let go.

This is sometimes called a "hard reset" or "hard reboot," as this will restore the modem to its factory default settings

Hope this helps

I can hear modem dialing out, but it continues to say ''no dial tone''. This is a brand new modem, that was replaced by Dell, after a lightning strike.

Check the modem diagnostics first off.

Do this by going to control panel / phone and modem options / click the modem tab and if there is more than one modem select the one you wish to test. Click properties then when the new window opens click diagnostic. then query modem after a few moments it should show the low level modem information in the box.

Any problems with diagnostics mean there is an issue.

Also check in your hardware list to make sure there is no hardware with exclamation marks. If so fix those first

It may be as simple as going to the dell support page and downloading a new driver from there. if its lists ok and its not a driver then check that it is properly seated in the slot. if its still not working there may be an issue with the modem itself

Mac and Thompson router

I've run into cable modems that don't like to use ethernet sometimes. In cases like this, I have to do a soft reset of the modem and things usually work again.

To do a soft reset, do the following:
  1. pull the power cord from the modem
  2. count to 5
  3. hold down the power button on the modem
  4. plug back in the power
  5. count to 30 while holding the power button (the modem should be blinking a lot)
  6. release the power button and see what happens.
