Why does the NIC
install as a generic PCI
Ethernet controller
under Other Devices in
the Windows 95/98
Device Manager?
When Windows 95/98 is installed after the NIC has
already been physically installed in the PC, Windows
95/98 may install the NIC as a generic PCI Ethernet
controller.
To work around this problem, follow these steps:
1In the Device Manager, double-click Other Devices.
2Click PCI Ethernet Controller, and then click Remove.
3Reboot your PC.
What if a red circle
with a line through
it appears over the
3Com icon in my
Windows system tray?
If you enabled the 3Com icon to appear in the Windows
system tray, and a red circle with a line through it appears
over the icon, the network link is lost (that is, the PC is no
longer physically connected to the network).
■Check the cable between the NIC and the hub or
switch. Make sure that it follows the appropriate cable
specifications. See Appendix A.
■Make sure that the hub or switch is powered on.
■Reboot the PC.
