This is quite common among people that do their own phone wiring and can cause serious connection problems and could eventually kill your modem. You could have your wiring reversed and never know it without testing it. The Radio Shack phone line tester part number is 43-104. We have seen quite often that people have incorrectly plugged in the phone cord to the back of their modem. You may not have the current modem driver installed.
Prolynx Internet updates our USRobotics modem drivers when they are available.
Try running the correct driver. K56flex chipsets DO NOT have enough memory on board to handle both K56flex and V.90 at the same time. This means that if you upgrade your K56flex modem to the V.90, you will only be able to connect using V.90. If you would like more information about this new dialing system, please see the USWest web page . Prolynx, Inc. is not responsible for any long distance charges incurred by the client.
