If you connect a GSM phone, make sure that the programming of the supplied PC
card is compatible.
Check that the communication software you are using is compatible with the PC
card: make sure that the driver selected in your communication software matches
your PC card programming (refer to your communication software user manual).
My modem connection is slow
Many factors influence modem connection speed, including telephone line noise or
compatibility with telephone equipment (such as fax machines or other modems). If
you think your modem is not connecting properly to other PC-based modems, fax
machines, or your Internet Service Provider, check the following:
Have your phone company check that your phone line is free from any line noise.
If your problem is fax-related, check that there are no problems with the fax
machine you are calling and that it is compatible with fax modems.
If you are having a problem connecting with your Internet Service Provider,
check that the ISP is not experiencing technical problems.
If you have a second phone line available, try connecting the modem to that line.
My Modem is not Responding:
N.B., you are strongly advised to always use the same PC Card slot.
Check that you have not inserted the card in a different PC Card slot to the one you
were using previously: if this is the case, your modem has been reinstalled as a second
modem (COM One Platinium Card Discovery V.90 #2).
