Troubleshooting Guide 

 

(You may print out the entire section for your easy reference) 

 

Q1:   This modem is set to V.90, but why am I getting slow connections to my 

ISP? 

 
A1:   The majority of telephone lines and ISPs 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. 

 

Q2: 

The modem hangs up when an incoming call is received. Why? 

 
A2: 

Disable the Call Waiting function for the Online Service, Internet Connection 
and/or communications software you are using. 

 

Q3:   When I tried to dial out, the system gave me an error message “No Dial 

Tone”. Why? 

 
A3:   Check your Telephone Cable connection. If necessary, plug out the Telephone 

Cable and reconnect the cable. 

 

To check if it is due to a faulty telephone extension cable that you are using, 
connect the cable to a Telephone set.  Listen to the handset dial tone. If there is 
no dial tone, there is most probably some problem with your telephone 
extension cable. 

 

Q4:   There are incomprehensible characters appearing on the screen. Why? 

 
A4: 

The data, parity and stop bit settings are incorrect. Try using the default values 
or check with your ISP. 

 

Q5:  My system does not detect the modem card when I boot up for the first 

time. Why? 

 
A5:   Make sure that your card is fully inserted into the PCI-Bus slot.  However, if 

you are sure that the card has been properly installed, do the following:
