Check the following: v Determine if the IRQ setting assigned to the Ethernet controller is also assigned to another device in the Configuration/Setup Utility program. Although interrupt sharing is allowed for PCI devices, some devices do not function well when they share an interrupt with a dissimilar PCI device. Try changing the IRQ assigned to the Ethernet controller or the other device. For example, for NetWare Versions 3 and 4 it is recommended that disk controllers not share interrupts with LAN controllers. v Make sure that you are using the most recent device driver available from the World Wide Web. v Run the network diagnostic program.

Check the following: v Make sure that you have loaded the network device drivers. v The network might be idle. Try sending data from this workstation. v Run diagnostics on the LEDs. v The function of this LED can be changed by device driver load parameters. If necessary, remove any LED parameter settings when you load the device drivers. Data is incorrect or sporadic. Check the following: v Make sure that you are using Category 5 cabling when operating the system at 100 Mbps. v Make sure that the cables do not run close to noise-inducing sources like fluorescent lights. The Ethernet controller stopped working when another adapter was added to the system. Check the following: v Make sure that the cable is connected to the Ethernet controller. v Make sure that your PCI system BIOS is current. v Reseat the adapter. v Determine if the IRQ setting assigned to the Ethernet adapter is also assigned to another device in the Configuration/Setup Utility program. Although interrupt sharing is allowed for PCI devices, some devices do not function well when they share an interrupt with a dissimilar PCI device. Try changing the IRQ assigned to the Ethernet adapter or the other device. The Ethernet controller stopped working without apparent cause. If the problem remains, call for service. Check the following: v Run diagnostics for the Ethernet controller. v Try a different connector on the hub. v Reinstall the device drivers. Refer to your operating system documentation.
