Troubleshooting modem problems
The information in this section may be useful if you choose to use a different modem that has
not been certified for use with Wave ISM (see page 5-3) and experience problems.
The following terms are used throughout this section. For a complete description of each term,
see “Connecting to the Wave ISM via a modem” on page 5-8.
•
Wave modem: The answering modem on the ISC1/ISC2.
•
Client modem: The calling modem on the administrator PC.
•
Remote connection: A modem connection made through a trunk port on the Wave
Server.
•
Local connection: A modem connection made through an analog station port on the
Wave Server.
The client modem connects, but cannot authenticate user name and password.
Symptom: This problem has been observed on Creative Labs modems, and on modems that use
the Conexant chipset.
Solution:
1. Connect to the Wave Server from the administrator PC via your network (not via the
modem connection) as described on page 5-5.
2. In the Windows Control Panel on the Wave Server, choose
Administrative Tools >
Routing and Remote Access
.
3. In left panel of the dialog, right-click on the Wave Server, and then click
Properties >
Security > Authentication Methods
.
4. Clear the 2nd checkbox,
Microsoft encrypted authentication version 2 (MC-CHAP v2).
5. Click
OK, Apply, No, and OK to save your change.
Once the client modem is connected to the Wave Server, other IP connections on the
administrator PC run very slowly.
Symptom: On the administrator PC, this problem affects IP applications such as your Internet
browser, e-mail, and so forth. This problem occurs because every DNS request is being routed
through the client modem.
