Mike,

Thank you for your reply. I am not sure if the Hub (Netgear DS 108)
supports Full Duplex - it may only support half. I have checked the docs
that came with the hub, but it mentions nothing about full/half duplex.
I guess I will have to wait till after the w/e to contact Tech Support @
Netgear to find out.

If the hub does support Full duplex I will certainly give it a try.

Regards,
Ric
