Under normal circumstances, the V.90 modem script should be selected because it enables the fastest modem connection. Be sure to contact your Internet Service Provider to ensure they are using V.90 compliant modems. If not, you should select the V.34 modem script.
If the modem does not connect, or the connection is dropped after a few minutes, the phone lines may have too much interference to sustain a connection at the higher speeds possible with the V.90 protocol. In this case, use the Apple Internal 56K (V.34) modem script, which directs the modem to connect at 33.6 Kbps or lower. This connection is more reliable in situations where the phone line quality is questionable.
To use the Apple Internal 56k (V.34) modem script, follow these steps:
2. Make sure the "Connect via" pop-up menu is set to Internal Modem.
3. Open the Modem pop-up menu and choose Apple Internal 56k (V.34).
4. If necessary, set the Sound and Dialing options.
5. Close the control panel. A message asks if you want to save the changes to the current configuration.
6. Click Save.
Note: On the Power Mac G4 (PCI Graphics), the modem script names are Power Mac G3 Int 56K (v.34 Only) and Power Mac G3 Internal 56K.
