Things to Try

  1. If working with an i240 USB Controller:
    • Make sure the label on the i300 power adaptor cable says "#iNet-300 v4" (version ≥ 4), and not just "#iNet-300" (which refers to earlier than v4). Click here for a picture of the v4 label.
    • Make sure you are on a 32bit or 64bit Windows Xp Service Pack 2 (Sp2) or newer computer.
    • Open the Device Manager and look for a USB device with a yellow mark next to it's icon. This mark shows that the device is not recognized or not installed correctly (with respect to the operating system). If you see the instruNet icon in the device manager and it is ok (no yellow mark), yet there is ANOTHER usb device attached to the computer with a yellow mark, then that device might be conflicting with the instruNet usb controller. Try physically disconnecting that device from your computer. It is possible for one buggy usb device to effect other usb devices attached to the same computer.
    • If you are attaching the instruNet controller to the computer via a USB hub, try attaching the controller directly to the computer (with no usb hub between computer and instruNet i2x0 controller).
    • Carefully re-read the i240 installation notes. To see these, click here.
  2. If working with an i200 pci or i230 pcmcia controller, make sure you are on a Windows Xp or newer computer.
  3. Power the computer Off and then On, and note that only one instruNet program can run at a time.
  4. Upgrade to the latest iNet32.dll, per the instructions here (this is free).
  5. Remove and then reinstall the driver which connects the i2x0 hardware to Windows, as described here.
  6. Make sure the i2x0 controller is properly seated in its socket.
  7. Try the card in a different slot within the computer, to try to determine if the problem is with the slot.
  8. Try removing non-essential cards in the computer to see if there is a conflict with another card.
  9. Try the i2x0 card in another computer, or try another i2x0 card in this computer, to try to determine if the problem is the computer or the card.
  10. Email to your instruNet supplier an instruNet diagnostic Report, as described here.
