TOPIC
This article explains why PPP might not be available as an option in the TCP/IP control panel, and offers solutions.
DISCUSSION
PPP is not listed as a choice in the TCP/IP control panel under the following circumstances. PPP Software Is Missing or Disabled Check the Extensions folder of your System Folder, you should have an extension with the words Remote Access or PPP in its name. If you do not, try reinstalling the PPP software. For more information about downloading OT/PPP, search the Apple Software Updates Web site at http://www.apple.com/swupdates . If your computer came with a Software Restore CD, and you are using the original system software that came with your Macintosh, Apple recommends that you use the software restore function of the Software Restore CD, instead of a custom installation of system components. There are also third-party implementations of PPP available, such as MacPPP and FreePPP. If you are using one of these implementations, check the documentation included with them, and try re-installing the software to see whether it remedies the issue. For more information about PPP solutions, refer to article 21073: " MacPPP 2.5: Read Me for Open Transport 1.1 " If you are using the Apple Internet Connection Kit, you should upgrade your PPP software to OT/PPP, Remote Access 3.x, or the latest version of a third-party implementation. The Modem Software Is Not Installed Correctly If you have an iMac, Power Macintosh G3 (Blue and White), or PowerBook G3 (Bronze keyboard), and you have an internal modem, you must have the correct modem extension installed in order for the computer to recognize the modem. You can usually tell whether this is the case by checking the Modem control panel. If the choice for internal modem is not available, it is likely that the modem extension is either not installed or inactive. You can re-install the modem software by custom installing it from the OS installer. If you have a PowerBook and are using a PCMCIA modem, you may need to install additional software in order for the modem to be recognized. Some third party PCMCIA cards come with software, which is required for the modem to be recognized properly. Consult the documentation that came with your PCMCIA modem for installation instructions. If you have a Macintosh using a GeoPort Telecom adapter, you must also install the Geoport/Express Modem software in order for the computer to recognize and use the modem, but this should not keep PPP from being listed as an available choice in the TCP/IP control panel. If your computer came with a Software Restore CD, and you are using the original system software that came with your Macintosh, Apple recommends that you use the software restore function of the Software Restore CD, instead of a custom installation of system components. There Is a System Software Issue An extension or control panel may be preventing the PPP option from being listed in the TCP/IP control panel. You can troubleshoot this issue by using the Extensions Manager. Build a custom set by duplicating the Mac OS extensions set and adding only the extensions needed for your modem software and PPP. For more information about extension conflicts, refer to: article 15926: " System 7.5: Accessing Extensions Manager To Troubleshoot Extension Conflicts " article 30929: " Mac OS 8.x: Extensions Troubleshooting/Extensions Manager Features " A "PPP not installed" message can be caused by some versions of AOL Link. For more information about this issue refer to TIL Online Archive Article 30064: " Internet Dialer: PPP not installed Message " If the choice is still not available for internal modem, or if the PPP choice is still not available, try performing a clean installation of the system software, modem software, and PPP software in combination. Be sure to export or write down your TCP/IP and PPP settings before performing a clean installation. For more information about performing a clean installation, refer to: article 43034: " Troubleshooting Handbook: Performing a Clean Installation " article 30691: " Mac OS: When & Why to Perform a Clean Install " The Modem Is Not Properly Installed or Active For PCMCIA modems used with PowerBooks that have PCMCIA slots, the modem should appear on the desktop when installed properly. If you are having difficulties with your PCMCIA modem, try ejecting and reseating the modem, or try inserting the modem in another slot if available. With internal modems, you may also have an issue where the modem is unseated, causing the Internal Modem choice to be unavailable in the Modem control panel. First, check the Modem control panel to see whether Internal Modem is an available choice. If not, then try the previous troubleshooting steps to check for software issues. If you have already tried re-installing the modem software, try resetting the PRAM. Keep in mind, after resetting PRAM, you may need to change your AppleTalk preferences in the AppleTalk control panel or Chooser if you have a modem or serial printer connected to your printer port. Resetting the PRAM makes AppleTalk active on the printer port. For more information about resetting the PRAM refer to article 2238: " Macintosh: How to Reset PRAM and NVRAM " If the modem is still not recognized or operating properly and it is installed internally, the modem may need to be reseated. Consult the documentation that came with your Macintosh for instructions on modem installation or take your computer to an Apple-authorized service provider for assistance.
