SYMPTOMS
Access to your internal network may become slow when Internet Connection Sharing is enabled. This behavior can occur if the computer contains multiple 3Com PCI 3C905B network adapters all sharing the same IRQ.



RESOLUTION
To resolve this issue, use another type of network adapter.



MORE INFORMATION
IRQ sharing is allowed, but 3Com reports this as a problem in the Readme file that accompanies the network adapter. Please check with 3Com for additional information about this issue.
