Xircom® PortStation Troubleshooting

Anytime the Xircom® PortStation exhibits erratic operation, use the AC adapter. Many problems seem to be related to lack of sufficient power.

  1. Always check the BIOS configuration.

  2. Set the Plug-and-Play OS setting to "off" or "no."

  3. On Toshiba* computers set Device Configuration to "Setup by OS."

  4. Check your Users guide for instructions to set the BIOS. If a computer does not have one of these configuration choices, verify that the BIOS revision is the latest available for the computer by contacting your computer manufacturer. Upgrade the BIOS if necessary.
Some pertinent Microsoft* Knowledge Base articles can be found on the TechNet* CD or the Microsoft website.

Using STDB92 with an external modem, STE10, STPS22, and STDB25 modules: When copying files from the server and downloading files from the BBS at the same time, both modem and network connections are dropped. If the STPS22 and STDB25 modules are removed the process works.

Gateway* Solo* 9100 with Windows* 95
With PortStation installed this machine intermittently hangs on a warm boot. The STE10 installs properly but on reboot it detects and installs as an unknown device. Rebooting the machine repeatedly has a variety of results:
  • The module operating properly
  • The module being listed as an unknown device
  • The laptop refusing to boot.
  • Occasionally, after a reboot, the display settings change and need to be reset.
