Troubleshooting Guide
This section provides a step-by-step solutions to problems that you may
encounter when using your modem.
This modem is set to V.90. But why am I getting slow connections to my ISP ?
Majority of the telephone lines and ISP are already supporting V.90 connections.
However, like all data connection, the connection is sensitive to the amount of noise
present in the phone line. Hence, only very clean phone line can get high
connection rate or throughput. You may want to check with your telephone provider.
The modem hangs up when an incoming call is received.
Disable the Call Waiting function for the Online Service, Internet Connection and/or
communications software you are using.
When I tried to dial out, the system gave me an error message No Dial Tone.
Check the connection on the telephone extension cable. If necessary, plug out and
plug in the cable. To check if it is due to a spoilt telephone extension cable that you
are using, connect the cable to a Telephone set and check for the Off-Hook Dial
tone. If there is no Dial Tone, most probably there is some problem with your
telephone extension cable.
I have done a diagnostics test of my modem and there is nothing wrong with it.
However, when I use a communications software, there seems to be an error.
Why?
Try to use a different telephony application like Microsoft Fax to fax a document. If
the sending of a fax is successful, then the fax function of your modem is working
fine.
Try to use Hyperterminal to dial up to a BBS. If the connection is successful, then
the data function of your modem is working fine.
Try exiting the communications software and running it again.
