Hi Alan,

Actually I do not really have another PCI network card, but I could 
switch the computer back to the other interface which is on the 
motherboard (does that one function as a PCI device?). As I mentioned in 
my first post, the current card I am using is an attempt to try to work 
around the problem (originally I thought it was the on-board 
controller), so I have my doubts as to whether switching back would help.

Nonetheless, I will give it a try again and let you know the result.

Thanks,
David
